INTRODUCTION
The in-depth study of migratory birds may well be a subject
you have never even considered teaching or learning before.
Whether you are a teacher of biology, geography, political
science or social studies, the topic of birds is clearly not an
ordinary curriculum component in schools today.
The study of migratory birds can be extraordinary, though,
because in addition to its novelty, it has the potential to:
1) provide an interesting and focused introduction to the
important topic of biodiversity and ecosystem protection; and
2) meaningfully interrelate a variety of school subjects that are
usually packaged separately and taught in isolation.
First, learning about migratory birds provides a focused
introduction to the crucially important planetary matters of
biodiversity and ecosystem protection, and of sustainable
survival for us all.
In addition, a focused examination of 'Neotropical' {meaning
New World tropical) migratory birds can link together the fields
of:
biology: including zoology, in studying the birds
themselves and their classifications, and techniques of
biological observation; and ecology, in learning about
the ecosystems in which the birds survive, and recent
serious problems in ecosystem protection;
geography, in exploring patterns of migration of the
birds throughout the Americas;
social studies, in focusing on how various cultures
impact the sustainability of bird populations and
natural habitats and ecosystems;
land use planning, and law, civics, economics and
political science, in examining how different nations
and' diverse cultures handle the increasingly important
issues of these international birds and of ecosystem
protection and biodiversity.
-------
In the timeless words of Aldo Leopold, "It is an irony of
history that the great powers should have discovered the unity of
nations at Cairo in 1943. The geese of the world have had that
notion for a longer time, and each March they stake their lives
on its essential truth."1
Each of these individual areas, and then the inter-
relationship among them that birds create, provides an out-of-the
ordinary vehicle for students to approach a meaningful topic in a
holistic, in-depth and integrated manner.
For both of these significant reasons, then, the study of
those 'ordinary' birds, waiting for you to discover them just
outside your window, has truly out-of-the ordinary potential, and
offers us all a truly extraordinary opportunity to see and
appreciate a paradise around us.
We all can become partners in helping to assure the survival
of this paradise around us. Understanding, appreciating and
valuing ecosystems and the miracles within them is a key first
step in this partnership.

COURSE GOALS
Next year, then ten years from now . . . twenty years and
fifty years into the future, will the students remember this
course? Will they have gained anything from it? Will they have
an awe, wonder and respect for migratory birds and for the
ecosystems that sustain us all? Will they value them, and
understand that protection of ecosystems is key to human
survival? Will they want to learn more about them?
This is the fundamental goal to think about when organizing
the class time.
Some students may not remember the difference between a
bluejay and a bluebird. Hopefully, all the students will keep
with them their chance to question, to explore and learn more
about, and to treasure birds, biodiversity, the natural world and
its sustaining ecosystems. But most of all, they will remember
you, the teacher. They will remember your interest in migratory
birds, in biodiversity, in the environment and humanity's
relationship to the natural planetary cycles. They will remember
the values you have placed on migratory birds and biodiversity,
and your sincere curiosity about, respect for, and valuing of
natural habitats and ecosystems.
So, most of all, your genuine appreciation for the beauty
and importance of the natural environment, your willingness to
question, wonder at, learn about, and value the natural cycles of
the world around us all, are fundamental to the success of this
course.
Don't shortchange the students and yourself, with dry,
predictable lectures. Instead, embark on a journey of wonder,
exploration and learning about the natural systems of this earth,
that every one of us can, and wants to, continue for the rest of
our lives.

A WORD ABOUT BIRDS
AND BIODIVERSITY
We are losing 'our' Neotropical migratory birds - - many of
which are the colorful and familiar songbirds - - at an alarming
rate2. We are losing intact natural ecosystems and the present
era biodiversity of this planet at a rapid and escalating pace3.
Human activity is now causing this planet to lose its incredible
and fragile ability to sustain human life4.
Studying migratory birds, then, is not a narrow enterprise.
It is a wide opportunity to key into and learn about, and learn
from, the natural world around us, and eventually to help learn
how to sustain our human civilizations on this planet over the
long run.
The hallmark Baltimore oriole, so familiar to us all, but
who has actually seen one lately? One source reports that
numbers of Baltimore orioles have declined about thirty percent
between 1980 and 19905. Or who has recently seen a wood thrush
or a rose-breasted grosbeak? These birds are incredibly
beautiful, glittering in the spring sunlight and offering their
haunting melodies. Their recent steep population declines are
communicating something to us, also, if we listen.
What are they telling us?
According to another source, population densities of
migratory songbirds in the mid-Atlantic United States dropped 50%
from the 1940's to the 1980's, and "many species became locally

extinct."6 The recent disappearance of the migratory birds is
not keyed to a sole discrete culprit, such as pesticide use,
which was the cause of songbird declines several decades ago.
The songbirds are but one relatively easily seen and
understood example of the frightening,recent decline in the
biodiversity of the present era that is threatening, in the end,
the ability of people to survive on this planet. Like the
classic canary in a mine cage, the demise of the birds may be
telling people something we need to know about our own survival.
The birds, then, can be a colorful key to learning broader
concepts of biodiversity - - which can be described as the
present era variety of life and its processes. Studying
migratory birds also leads meaningfully into the broad area of
ecosystem protection and ecological sustainability for the human
population.
The experiences of the students in this class therefore may
be bittersweet. Bitter, because the truth is that some of the
species the students may see or learn about this year could well
be extinct by the time the students become adults. And the
learning may be bitter, as well, because unfortunately the truth
about the rapid decline of species can be harsh and frightening.
But the class experience can be very sweet, too, as the
students begin to see and hear first-hand the beautiful natural
habitats and ecosystems right around them, but which they
probably never really noticed before. And the students will be
learning key concepts about natural ecological systems, and how
humans relate to them, that will be their essential tools in a
fundamental enterprise: helping to sustain their own long-term
survival, and the survival of their own offspring, amid the
magnificent natural systems of this planet.

-------
APPROACH
This curriculum focuses on the students' own
experiences and ideas, and attempts to personalize the topic
of migratory birds in a way that will have long-term meaning
for each student. The in-depth and integrated study of
birds is important, but the overriding goal of the course is
to develop in each student a curiosity for, a delight and
intrigue in, and a respect for, the topics of migratory
birds, biodiversity, and human relationships to natural
systems that will last a life-time of independent pursuit.
As such, this course does not require an instructor who
is even trained in zoology. A teacher who is willing to
explore, listen to and learn along with the students is all
that is fundamental. Lectures on the taxonomy and
scientific classification of birds are simply not necessary
for this course, and frankly would be counter-productive to
the overall goal.
What is important is for the teacher to feel secure
enough in the essential areas of inquiry to be able to
recognize, link and reinforce the main concepts, and to help
the students carry on thoughtful and meaningful discussions.
Typically, an instructor can do this by becoming familiar
with this curriculum package, and by taking the initiative
to help obtain materials on particular areas of interest.
Of course, any specialized expertise of the instructor can
provide an individual enhancement to the course. But since
the basic approach is of personalized discovery, it is
simply not necessary for the leader to feel obliged to feed
a package of facts to the students.
When I led this course with a group of seventh and
eighth graders, I asked them in the beginning who would be
teaching the course. After they pointed at me, then they
suggested every member of the school faculty and still I
shook my head 'no', they had no more ideas. When I called
each one of their own names, and identified them as teachers
of each other, they weren't sure how to react; they looked
at each other in a new and unfamiliar light. But throughout
the course, each student was entitled to respect as a
teacher of the others, and each person's ideas were listened
to and accorded importance. It was a journey of teaching,
learning and respect, for all of us together.
It was the birds themselves, though, that taught us the
most. This is a key part of the educational experience.
Just as 'teachers' can learn from 'students', humans have a
great deal to learn by carefully listening to and valuing
the natural world around us.
-------
Thus, a key to one crucial awakening of the course
itself - - that humanity has an immense journey of learning
in front of us, if people would only open our eyes, ears and
minds to the natural world around us - - can be first
introduced by redefining traditional roles of the 'teacher'
and the 'students'.
Welcome, to a challenging and rewarding journey of
discovery and wonder, for all.

things of lesser worth? The goose who trades his is soon a

"The edifice of civilization has become astonishingly
complex, but as it grows ever more elaborate, we feel
increasingly distant from our roots in the earth. In one
sense, civilization itself has been on a journey from its
foundations in the world of nature to an ever more
contrived, controlled, and manufactured world of our own
imitative and sometimes arrogant design. And in my view,
the price has been high. At some point during this journey
we lost our feeling of connectedness to the rest of nature.
. . . The ecological perspective begins with a view of the
whole, an understanding of how the various parts of nature
interact in patterns that tend toward balance and persist
over time. But this perspective cannot treat the earth as
something separate from human civilization; we are part of
the whole too, and looking at it ultimately means also
looking at ourselves ..."

OVERVIEW
This curriculum is organized into several broad, sequenced
segment areas: A) The Wonder of Birds, Migration and Survival in
Natural Ecosystems; B) Flight to New World Habitats; C)
Discovering Birds First-Hand; and D) Problems and Partnership in
Biodiversity. Classes are provided in sequenced topics within
each of the segment areas.
The curriculum provides numerous focused classes on
migratory birds and our environment. Of course, given the
breadth of this subject, it is not possible for the students to
examine and consider every topic area in depth. Accordingly,
this curriculum provides a compass and a road map of the major
route to follow in getting to the destination. A number of the
rewarding side roads and key landmarks of this journey of
learning are not set out in depth in this curriculum, but are
identified for the students and teacher to explore more fully,
perhaps drawing upon traditional texts and source materials that
are already in use by the class for areas such as political
science and sociology. In those instances, this curriculum
identifies these related topics as a "Link" to the general topic
area, and the teacher is alerted that these classes and subjects
can be integrated with the otherwise available curriculum
materials on that specific topic.
The teacher can go up as many side trails as desired in this
journey of exploration, but keep in mind that it may not be a
complete and rewarding learning experience for the students if a
side trail is explored in such depth and length such that there
isn't enough time to reach the destination at the end of the main
trail, or if you have to hurry quickly up the rest of the trail
and won't get a chance to carefully explore the important
attractions on the latter half of the trail.
Nevertheless, in deciding whether to indulge a class's
interest in learning about a particular aspect in greater depth
than is scheduled for the classes of this curriculum, the teacher
should keep the basic Course Goals in mind. Reaching the end of
this curriculum and superficially "covering" the material and
information may not achieve the "Course Goals" for your group.
Thus, the teacher will need to use the "Course Goals",
specified above, as a guiding light in deciding whether to adjust
the schedule to accommodate the interests of a particular group
of students.
Because of the need to schedule field observations (Segment
C) according to the best time for your area, the course leader
will need to plan around this, and adjust the timing of the other
segments, as necessary. See "Field Trips: Logistics", below.
-------
Segment A) The Wonder of Birds, Migration and Survival in
Natural Ecosystems
(Classes #1 - 3)
Initially, the curriculum challenges the students to focus
on the life and journeys of the birds that are right outside
their window, that the students have likely not even thought much
about before. In this way, the students are awakened to look at
the world around them in a new and unexpected light. These are
things they have taken for granted, and probably have not really
noticed nor appreciated before.
The life of migratory birds is incredible and astonishing,
and all the more so when related to the students' own experiences
in travelling (Class #1). Bringing concepts down to a personal
level can be a way of thinking about how extraordinary the
survival of migratory birds is, that students will find hard to
forget. It can be a key eye-opener to the natural world around
us.
Bring out quarters, one for each student, and flip them to
feel the weight of one migratory bird, the blackpoll warbler,
which migrates thousands of miles, each way, without a suitcase.
Class #2 continues to focus on the students' own personal
view of birds, and begins to develop their individual
appreciation of the diversity and wonder of migratory birds. The
'Personal Survey' that is presented in this class can be repeated
near the end of the course (Class #22). A comparison between the
two surveys can show each student one individual measure of how
much their own general understanding of the topic has expanded
through the course.
Class #3 is designed to help focus students on some of the
mysteries and miracles of migration, and survival of birds
throughout their journeys.
10
-------
Segment B) Flight to New World Habitats
(Classes #4 - 9)
Class #4 is set up to be an immersion into the South
American rainforest. The lush rainforest is looked at as a total
habitat, of which birds are an important piece. The rich and
colorful beauty of the rainforest is a treasure to explore, even
in second-hand pictures. ' It leads into a mystery to which no-one
really knows the complete answer . . . why would birds ever leave
that warm paradise, to come to North America? These and similar
questions are posed and considered in Class #5.
These questions stand on their head conventional teaching
that the birds are really North American residents that just go
south temporarily in the cold winter to 'vacation'. If looked at
from another viewpoint, that the birds are really South American
habitants, we can begin to honor and appreciate the colorful and
melodious gifts the birds bring to North America every spring by
leaving behind their lush rainforest homes and making incredible
journeys to the United States and Canada.
Appreciating the magnitude, length and difference of these
journeys, and locating the islands, continents and political
countries along the way is the focus of Classes #5, 6 and 7.
This segment of the course can be expanded for an in-depth focus
and investigation of these countries, if the instructor desires.
In addition to opportunities to discuss and investigate the
political and social conditions in the various countries, it is
an excellent opportunity to focus on comparative land use and
sociological patterns, examining which types of land use and
culture provide habitat in which the birds, and other wildlife,
can survive and biodiversity can flourish.
The key work of ornithologist Frederick C. Lincoln provides
the important migratory charts which are fundamental to this
portion of the course.
The students' own interests can provide the basis for an in-
depth examination of particular habitats along the migratory
routes. A student who has been to the Gulf Coast or to Florida
can be invited to prepare and share personal observations about
these habitats, and the current challenges and opportunities
these habitats pose to survival of migratory birds. In addition,
students can research a particular geographic area and present
their own conclusions about how a migratory bird would fare
there.
During the spring, the birds' progress to their summer North
11
-------
American habitat and ecosystems can be anticipated and traced by
the students. Students can be introduced to the concept of
isochronal charts (Class #3). Local news and newspaper reports
can be monitored for the sighting of 'the first robin' and for
Neotropical migrants.
Classes #8 and 9 are designed to give students appreciation
and understanding about how scientists have figured out how and
when bird migration happens, and how the students themselves are
capable of doing basic scientific work.
Segment C) Discovering Birds First-Hand
(Classes #10 - 16)
Enhanced observation skills, featured in Classes #10 and 11,
will make the students' eventual field' observations more
meaningful. One classroom period, Class #11, is devoted to the
sheer discovery and exploration of an avian field guide. The
students are encouraged simply to discover for themselves the
astonishing diversity of birds. For the class I 'led', this
otherwise unstructured hour proved to be a fascinating journey of
personal discovery. The students had never before had the
opportunity to explore and examine page after page of pictures
and information about colorful, different and diverse birds. A
few questions can be prompted here, if necessary, but for the
most part the students will remember favorably this experience of
discovery far longer than they would any lecture on the taxonomy
of birds.
At some point, either in this class period, if there is
time, or at a resting spot during a field trip, it is very
helpful to focus the students into the organization of a field
guide for birds . . . the related avian families, the index and
the migratory charts. These are not for purposes of
memorization, but for aid in finding out about the particular
bird, and how it relates to the the'mes of the course.
Another important activity is to play pre-recorded tapes of
bird songs. I have found this best to schedule flexibly, among
the field trips, because with the unpredictable spring weather,
one trip at least, inevitably, will need to be postponed.
Listening to tapes of bird songs is some solace to students who
are disappointed at missing a refreshing spring walk. And
listening to tapes of bird songs is surprisingly uplifting and
12
-------
intriguing . . . bird songs can be charted on the blackboard and
help provide students with a new dimension and expertise in
natural observation. This activity is scheduled for Class #14,
among the field trips.
The 'field trips' to actually observe birds out of doors, in
natural habitats, should be scheduled for the most appropriate
times for your area. Although some birds can be found virtually
anywhere, it may be helpful to select nearby spots where a
variety of birds may be observed, to reward and challenge the
beginning observer. However, the behavior of even one common
pigeon, starling or crow can provide interesting material for the
beginning bird-watcher, and can help students to notice the
natural world around them that they have not looked at closely
before, even though the observations may not be of a migratory
bird.
Field trips are included in this curriculum as Classes #12,
13, 15 and 16. See "Field Trips: Materials and Logistics",
below, for comprehensive information on scheduling field trips.
Segment D) Problems and Partnership in Biodiversity
(Classes #17 - 21)
This segment provokes students to think about broader issues
concerning birds as important populations in the earth's natural
systems, and to realize that migratory birds raise crucial issues
at the local, national and international levels, particularly*
regarding ecosystem protection. The final classes of the course
are designed to be upbeat, focusing students on the existing
tools humans have to protect migratory birds and biodiversity,
and how the students can use these tools effectively.
Class #17 centers on discussion of two eye-opening articles
about the serious declines in migratory bird populations. The
articles will need to be assigned as homework reading previous to
this class.
In Class #18, the focus expands to the general and extensive
problem of loss of natural ecosystems and biodiversity. The
decline in bird populations is an indicator of this problem.
Some of the recommended reading material for this class contains
scientific terms with which the students may be unfamiliar. For
this reason, a number of these terms are assigned as a homework
13
-------
learning assignment during the earlier field trip classes.
Obviously, the ideal situation would be for the students to be
solidly familiar with these biological concepts. But such
instruction is beyond the scope of this course, and it is not
essential for understanding the key covered points from these
articles. Some familiarity with the terms, however, will enable
the students to read through the assigned passages without
becoming bewildered.
Conversely, the realization that learning what these terms
mean can be keys to an in-depth understanding of broader
biodiversity concepts and issues. The experience may reveal to
the students the importance of studying these otherwise remote
and foreign terms, as the students participate in more basic
biology courses as they continue their school careers.
Class #19 can be a continuation of discussion of
biodiversity issues, and it also introduces new reading materials
and concepts. "Land use" is the central theme.
Class #20 centers on an introduction of significant,
existing tools we have to protect birds and biodiversity,
including the Endangered Species Act. Students are encouraged to
actually examine provisions of this laws, and to read an
interpretive article on the Endangered Species Act, which
includes a detailed discussion of the survival of one songbird
species.
In Class #21, the focus shifts from the national and
international, down to the local level. Newspaper articles
dealing with issues in the students' own community are the source
materials here. The crucial message is to have students see how
broad national and international issues are played out at the
community level, and conversely, how community issues on
biodiversity are impacted by the umbrella national laws and
policies studied in Class #19.
Because it can vary so much from state to state, no specific
source materials have been identified in this curriculum for
state policies, laws and initiatives dealing with migratory birds
and biodiversity. However, this is an important area for the
leader or the class to look into, obtain materials on, and weave
into the discussions for either Class #19, #20 or #21. States
are important players in this area. Even the lack of any laws
and policies in your state dealing with protection of migratory
birds, biodiversity or encouraging preservation of natural
habitat areas is important to find out about. The Partners in
Flight newsletters (see Preparation, Section V, below) contain
helpful information identifying migratory bird conservation
contact people for many states. Be sure you write to them well
before the course begins to be placed on their mailing list.
14
-------
Depending on the group of students you have, the topics
covered in this Segment could be discussed and explored in
greater depth, and at greater length than provided in this
curriculum. You might consider this possibility when scheduling
your course.
Course Conclusion and Challenge
Finally, Class #22 is scheduled to be a repeat of the
'Personal Survey' given in Class #2. It can be a good concluding
class to remind students of the path they have taken in learning
about the importance of migratory birds and biodiversity.
Hopefully, students' interest in the subject of birds and
biodiversity, and ecosystem protection will continue beyond this
course. You might consider preparing suggestions for their
further reading, and appropriate periodicals to which they might
want to subscribe, or to look for in the library when they can.
A few are suggested in Resource Information, Section V, above.
Students are embarking on the journey of their lives. Be
sure the students leave the class with their bird-watching 'life
lists', which they may want to continue adding to, on their own,
throughout their life-journeys. Challenge students to notice the
birds, no matter where they may be.
Bring out a quarter, as was done in Class #1, and encourage
students to think about the amazing wonder of migratory bird
journeys and survival, and the survival of us all, because of the
richness of biodiversity and natural ecosystems, with every
quarter they use.

GENERAL PREPARATION,
MATERIALS AND LOGISTICS
Inspired by the prospect of teaching my first class on the
migratory birds of the Americas, one of my first organizing tasks
was to set off on a purposeful outing downtown, to the center of
a major North American city, to a major map makers store. I
wanted to get several copies of a tool I deemed essential for the
class ... a large map of just the Americas - - North, South,
Central and the Caribbean - - depicted in relationship and
connection with each other.
I could not find such a map.
My fascination with the chance to browse leisurely through
the map store and to explore the various maps of the world became
mingled with increasing embarrassment as I, a college major'in
Latin American studies, could not locate anything that even
resembled the Americas map that I wanted for the class. The
salesman then helpfully and carefully searched the store racks
for me. Finally, he said to me authoritatively that, given the
Earth's contours, it was impossible to make such a map of just
the Americas.
Failing in my very first attempt to organize a fundamental
piece of this course on American wildlife, I stared at the
salesman in astonished disbelief.
The lack of a map of the Americas could have been seen as a
serious obstacle to this course. Instead, it opened my eyes as
to the potential importance of a curriculum that focuses on the
natural links and connections between South, Central and North
America that sustain us all. In a world where global
understanding is becoming increasingly essential, the
unsuccessful map search incident starkly showed me that there is
a real need to focus on the basics of the relationships among the
Americas, our peoples, and the mutual ecosystems that help
sustain us. It is a challenge to us all.
Almost fifty years ago writer Aldo Leopold, observed in
Wisconsin that "... on cool August nights you can hear
whistled signals [of the upland plovers] as they set wing for the
pampas [of Argentina], to prove again the age-old unity of the
Americas. Hemisphere solidarity is new among statesmen, but not

-------
Let's not waste the next fifty years in discovering the
connection of these ecosystems.
Let's not waste the next fifty weeks.
This curriculum can help chart the territory of the Americas
and the common natural systems that have been sustaining us all
this time. But in making this journey, the teacher and the
students will need to be resourceful.
Don't be discouraged if you have to help map part of the
territory. The teacher should identify needed classroom
materials early on, ideally well before the course actually
starts, so there will be sufficient time to obtain all the needed
materials, and to improvise if important materials cannot be
located. An ample list of possible source items is presented in
the following sections, that can give a solid start to any course
of this topic. There is plenty to go on, and our perseverance
and creativity can lead us the rest of the way.
I finally did locate a connected map of just the Americas,
with an excellent depiction of migratory routes, published by
National Geographic. The map is still available for purchase
(see Maps, III, below).
I) General Course Scheduling and Logistics
This course is designed for the middle or high
school level.
The curriculum is designed for a spring semester
of once a week class meetings of approximately an
hour in length. It can easily be adapted,
however, for other structures such as more
frequent meetings, or longer class periods, either
covering several classes at once, or covering
material for a particular class in greater depth.
It could even be structured as a one-week
intensive course.
Or, it could be expanded as a once a week course
to meet over an entire school year. In that
event, field trips could be added and scheduled to
observe the interesting fall migrations of geese,
hawks and other birds of prey. Even teenagers are
awed by these impressive large birds.
Other curricula are available dealing with the
migratory bird topic in a different manner, such
as adding isolated topics on birds to already
18
-------
existing standard school subjects. If the
approach or structure set forth in this curriculum
doesn't work for your school, try something else,
but don't give up on this important topic.
When trying out this curriculum, I led a group, of
approximately ten students. This was an excellent
group number. You may not have the choice but to
work with a larger group. The in-school
activities should work fine, but organizing and
supervising the field trips will be more
complicated.
II) Field Trip Materials and Logistics
A) Materials
1) Field guides
Ideally, each student should have their own field
guide to birds. A reputable source, such as North
American Birds. (Peterson, 4th ed.), costs about
$16. Students and their families could be asked
to pay for this directly, or other funding sources
could be considered, such as community sponsors,
an allowance from a parent-teachers association,
or a fund-raiser.
The course will still work fine if students share
the field guides in pairs.
2) Binoculars
Binoculars or field glasses are very expensive,
well beyond modest course fees, fund raising or
stipends. If needed, an acceptable course can be
taught without them at all. So don't give up on
leading a migratory birds course because you or
your students don't have binoculars.
In one of the first classes, you can ask each of
the students if they or their family has
binoculars that they will be able to use for the
19
-------
field trips. Be sure students do not bring
expensive or special binoculars to school, unless
your school has the ability to assure the safety
of this expensive equipment.
With the several old or inexpensive pairs the
students are likely to have, along with your pair
or two, and an old extra that an assistant leader
or field trip guide may have, there will be enough
for everyone to have a chance to see the birds
close-up. The resourcefulness of the students and
other school personnel interested in bird-watching
should not be underestimated. In the class I led,
one of the students arranged to borrow a nice pair
of binoculars from the school janitor, who kindly
unlocked the glasses from his supply closet each
week before the field trips.
3) Life lists
The students will be intrigued by the idea that
they can begin recording a list of all the birds
that they see, a 'life list', their own personal
list of all the birds they see throughout their
life. And when they first start bird-watching is
the best time to start a life list. Call a local
nature center in your area for free copies of a
checklist of the birds students are likely to see
in the area, that can be used as a first life-list
record. Each student will need their own copy.
B) Logistics
1) Trip scheduling
Decide how many trips you want to include in your
course, and find out the time you will have
available for them. In my course, I planned for
four trips, each to take a double class period.
Even though the trip locations were all within a
mile of the school, there just wasn't enough time
in one standard 50-minute class period to get to
the trip destination, get oriented and organized,
to carefully explore the area for wildlife, and
then to return in time for the next class period.
The double-period solution worked well.
Four trips was a good number, because it allowed
flexibility in the event of bad weather, and it
20
-------
provided opportunity for important reinforcement
of identification of birds observed and ideas
learned, from one trip to the next.
2) Trip timing
Discuss with an experienced local bird-watcher the
best time during the spring to observe migratory
birds in your locality. In the Mid-Atlantic area,
for example, trips are best scheduled for after
the weather gets warm, but before the leaves come
out on the trees.
Trips are ideally scheduled for as early in the
morning as feasible, given your school schedule.
That is when the birds are actively feeding and
singing.
3) Trip locations
The destinations of your field trips will of
course be determined by your locality. But be
sure to look beyond the obvious. Birds can be
observed in urban areas, where there are nearby
natural areas that might be inhabited by an
interesting and rewarding array of birds. A small
park close by may offer opportunities to observe
in-depth the behavior of common crows, pigeons or
starlings in a new light. Also, don't overlook
the zoo as a field trip location. But, be sure
you focus on the birds. The zoo may even offer
speakers on birds or bird walk leaders.
In contrast, a rural or suburban area presents
different challenges to successful field trips.
The most well-known areas may have steep entrance
fees or leaders who, although bird experts, don't
relate well to the students. Aim for areas and
leaders that will relate to and interest your
students.
Be sure, if you are going to an area that is not a
public area, that you have made appropriate
arrangements with the property owners to visit
their property.
21
-------
Also, keep in mind that nearby areas may be best
to visit on your trips, because students will be
able to go back to them themselves, well after
your course is over. The field trips can serve as
an important introduction of students to nearby
natural area locations that they will be
interested in returning to, to observe wildlife,
and can easily go back to themselves or with their
families.
4) Trip preparation
Be sure your transportation is confirmed and the
directions to the destination are completely
clear. Know how long it will take to get there.
Signed standard school permission slips are
essential, of course. Confirm with the students
exactly when and where to meet.
Advise the students as to appropriate field
attire. In many areas, protection against ticks
and Lyme disease are very important. Advise
students to wear long pants, long-sleeved shirts
and head coverings, all of a light color. Follow
advisories issued for deer ticks and other local
problems, including staying away from areas that
deer go to, and keeping on established paths.
5) Trip leaders
You may want to ask experienced bird-watchers from
the community to help you lead a trip. Many
people have a wealth of bird-watching knowledge
and experience, gained over a life-time, that they
are very gracious to share. This is an invaluable
human resource, that is important for students to
recognize. The knowledge of experienced birders
is impressive, and it provides inspiration for the
beginning student that it is possible to become
expert in this subject.
It is your job as teacher/coordinator to screen
potential speakers and leaders to find those who
are genuinely interested in working with students,
and who relate well to them. A highly experienced
leader who is not interested in the students or
who does not relate well to them is not a good use
of anyone's time.
22
-------
Ill)
In any event, try to have enough adults to
accompany you so that you have a 1:4 or 1:5
students ratio. The assistants need not be
birding experts. If they are responsible, and
familiar with how to approach using binoculars and
field guides, and if they are enthusiastic, that
is all that is needed.
The best field trip my class had was on a cold,
misty day that indeed did deteriorate into
intermittent drizzle, and the nature center leader
was stuck out in the woods with another group.
Confined to the porch of a small log cabin, this
became our special observation deck, as the
students were encouraged to discover for
themselves, and themselves find in their field
guides about, the colorful variety of birds that
ventured, with songs that warmed us, into the
small natural area clearing.
6) Trip protocol
It should go without saying that in no event
should bird observers harrass or disturb the birds
that are being observed. Intentional malicious
acts are clearly inappropriate. Over and above
that, be aware that even well-meaning activities
are inappropriate, such as disturbing a nest, eggs
or young birds. In some cases, these activities
are even illegal. Demonstrate to the students
that they can learn a great deal by observing, and
by not interfering with the activities of the
birds.
In this course, the purpose of maps is not to tack
impressively on a wall and point at with a
distancing instrument.
Buy a few cheap world maps (they cost about $3
apiece in general bookstores or paper supply
stores) so they can be marked up, breathed over,
explored, and understood. Be sure to bring one or
more to each class. The world maps can be used to
show all the Americas in relationship to one
another.
23
-------
Additionally, a large map of the Americas, with
the reverse side featuring a superb depiction of
dozens of migratory routes, is still available
from National Geographic. The map can be ordered
for $2.65 by calling 1-800-638-4077. The purchase
includes the National Geographic volume associated
with the map. Ask for Vol. 156, No. 2, August
1979.
See Classes #5 - 9 for how the maps can be used.
Maps are indispensable. Use them as much as
possible.
IV) Recorded Tapes of Bird Songs
For Class #14 (Listening to, and Hearing,
Biodiversity), you will need a pre-recorded tape
of bird songs. These are generally available at
nature center stores and museum stores, or you may
find them or be able to order them from a local
bookstore. What you are looking for is a cassette
tape containing about twenty segments of recorded
songs and calls of individual, identified birds.
Look for a tape that features birds found in your
area. These tapes generally come in a package
that contains a booklet identifying the birds
featured on the tape. The booklet will be useful
for the teacher in preparing the class, and it is
not necessary to distribute to the students.
These tapes typically run in the $10 to $20 range.
If you are unable to find a source in your area,
the Cornell Laboratory of Ornithology (address in
(V)(D), below) is one possible source from which
you could order a tape.
24
-------
V) Resource Information on Migratory Birds
There is ample information currently available on
migratory birds and their current plight for an
introductory course. Below is a list of helpful
possible sources, and sources of further
information. If you are considering obtaining any
of these, it is a good idea to try to get them
before the course begins. Or, if they are to be
used as specialized student research materials,
allow enough time for the students to obtain them.
This curriculum does not recommend or require use
or reading of any of the identified possible
sources. Rather, it is left up to the course
instructor to choose and decide on appropriate
source material. The sources identified below are
provided as possibilities solely for the
convenience of the instructor.
There are an increasing amount of publications on
ecosystem protection, biodiversity issues, and
about migratory birds, and it is simply not
possible to include them all in an introductory
course. The teacher is cautioned against trying
to include too much, and overwhelm the students.
This course curriculum schedule is designed to
focus on particular aspects of this large topic,
so that the issues are presented in an interesting
and integrated progression.
The teacher can always recommend other materials
for the supplementary reading of interested
students.

SEGMENT A
THE WONDER OF BIRDS, MIGRATION
AND SURVIVAL IN NATURAL ECOSYSTEMS Class #1
The Miracle of Migration
and Survival in Natural
Ecosystems
******************
OBJECTIVE: Awaken curiosity about, and wonder at, the amazing
miracle of bird migration.
THEME: Long distance journeys pose difficult challenges
to meeting basic needs such as food, water,
clothing and shelter, and finding your way, for
people and the birds.
CLASS
ACTIVITIES:
I. Identify how people obtain basic necessities while
travelling:
A. On a map, locate long-distance locations to which each
of the students in the class have travelled.
B. Ask the class members to identify what they took with
them on their trip in order to stay warm, protect
themselves from the weather, have a place to sleep,
have enough to eat and to drink. Record this list on
the blackboard, overhead projector, or a large flip-
chart pad (a permanent list may be advantageous for
future reference).
In addition to obvious items, encourage the students to
think about less obvious articles, such as:
- maps (to know where they were going)
- compass (to know direction they were going in)
1-1
-------
- water (they probably took this for granted)
- food (if they didn't carry it all, they needed
to bring money to buy it)
If a class member went hiking or on a camping trip,
this experience may warrant detailed discussion of how
difficult it was to obtain basic necessities for
survival and comforts that they may take for granted
around their home.
Encourage class members to identify other unique
complications or problems that they faced in travelling
away from their home.
C. Open up a pre-packed suitcase or backpack (see
"Preparation", below) and identify each item that you
have packed for a long trip, and the purpose of the
item. You can run quickly through items that the class
has already identified in (B), above, and dwell on
those they hadn't thought of.
Another approach, quite a bit more dramatic, is to
begin the class by making an entrance with the suitcase
or backpack, and go through the contents before doing
the exercise in (B), above.
D. Illustrate how heavy the suitcase it, and how it holds
only a small portion of the travel items the class
identified, and how it holds only enough food and
shelter materials for a very short journey.
II. Identify basic facts about migratory bird journeys:
A. Ask students to take out a quarter; hand out quarters
to each student who doesn't have one. (Expect the
students to toss and flip their quarters.)
B. Hand out a copy of the Blackpoll warbler page (see
"Handouts", below) to each student.
C. Focus attention on the over 2,000 mile journey of this
quarter-weight bird, which doesn't carry any suitcase
or backpack, but which finds ways to survive.
D. Ask the class to think about how the bird survives and
how the bird gets basic necessities such as water,
food, shelter and warmth, without bringing anything
with it, or carrying a suitcase. Explain that these
are the kind of questions we will try to explore in
this course.
1-2
-------
E. Suggest that, each time they handle a quarter, the
students think about the amazing journey of the
blackpoll warbler and other migratory birds.
III. Course introduction:
Explain to the students that this will be a course on
migratory birds, and they will learn about birds and
the environment. Explain other general course
information, including that this subject area can link
together a number of topics, including science,
sociology, geography and political science.
PREPARATION:
A. Pack suitcase;
B. Obtain quarters for each student;
C. Copy blackpoll warbler page for each student.
RESOURCES NEEDED:
A. Suitcase or backpack, packed with various items
representative of survival necessities while on travel,
such as the following:
LIST OF SUITCASE ITEMS
- sweater
- warm jacket
- hat
- gloves
- change of clothes
- shirts (warm, and warm-weather)
- shorts
- pants
- dress clothes (for dinner!)
- alarm clock
- toothbrush
- wash cloth
- pillow (if room for it)
- shoes
- boots
- sandals (for warm weather)
- sunscreen
- sunglasses
- pajamas
- socks
1-3
-------
- raincoat
- food
- water
- money
- maps (South America, North America, and local)
- compass
- alarm clock
- band-aids (for injuries)
- umbrella
- flashlight (to see at night)
- phone book and address book (to find your
friends)
Use your experiences to include additional useful
items from your own journeys.
B. A quarter for each student;
C. Copies of blackpoll warbler illustration (see
"Handouts", below);
D. Blackboard, or overhead projector and sheets, or large
flip-chart pad.
HANDOUTS:
Blackpoll warbler illustration, from "Birds Over
Troubled Forests", p. 16.
HOMEWORK TO ASSIGN:
Have students write about:
1. What is a migratory bird? ( no research
needed, just identify the current state of
their understanding); and
2. If migratory birds don't carry suitcases, how
do they keep warm, stay cool, get enough to
eat and drink, and find places to rest and to
sleep? (Again, no research needed, just have
students write down their own thoughts).
FOLLOW-UP:
Put away suitcase items, or repack for another class.

THE WONDER OF BIRDS, MIGRATION
AND SURVIVAL IN NATURAL ECOSYSTEMS Class #3
Starting the Migratory
Journey
OBJECTIVE: Organize and prepare the students for beginning to
learn specifics of migratory journeys.
THEME: There are many challenging questions about
migratory birds, that still remain to be explored.
CLASS
ACTIVITIES:
I. Review of Homework from Class #1:
Redistribute Homework papers from Class #1. Ask
students to share their ideas and thoughts from
this Homework assignment. Remember, every thought
and idea is a useful one! Reassure students that,
although they may not have all the answers, this
course will give them the chance to help find the
answers to these questions.
Discuss the answers.
II. Review of Homework from Class #2:
Ask students to take out the Homework assigned
from Class #2. Ask students to share their
thoughts from the Homework assignment from Class
#2. Discuss them.
III. Discuss Course Logistics:
Provide the students with a clear overview of the
course, and an individual printed calendar
3-1
-------
schedule of the classes, and discuss with them the
dates for which the field trips are scheduled.
Identify and discuss logistical concerns related
to field trips.
IV. Introduce that Spring Bird Migration is Beginning:
Hand out copies of the isochronal map provided in
"Handouts", below, and lead the class in
discovering that it depicts the general times that
particular species of birds are found in certain
areas on their spring migratory journeys. Be sure
to identify where the birds are at this particular
time.
V. Introduce Research into Habitat Areas:
A. Introduce the students' Homework assignment.
Students will be choosing to focus on specific
habitat areas along the migratory paths for their
individual research:
- Tropical rainforest
- Gulf Coast
- Caribbean
- Your local area (ask the students to
explain, if they can, what kind of a
habitat they live in)
- Northern United States
- Canada (including Canadian forests)
- Other geographic areas the students may be
interested-in examining along the migratory
routes
B. Make assignments. Students working on the
rainforest will need to prepare their research for
next week.
C. The students will need to research several key
questions for each area, set out below in the
"Handouts" section.
You may want to copy the page identified in
"Handouts" and provide it to each student.
3-2
-------
PREPARATION: 1. Bring Homework papers from Class #1.
2. Organize a calendar schedule of the course,
and bring a copy for each student.
3. Make copies of the isochronal map identified
in "Handouts", below.
4. Make copies of the research questions for
each student.
5. Collect and bring information on the tropical
rainforest, for the students who will need to
make their presentation in the next class.
RESOURCES NEEDED:
Any available information about the rainforest.
See possible sources in "Resource Information on
Migratory Birds" in General Preparation, Materials
and Logistics, above.
With the increased attention on the rainforest in
recent years, there is a wealth of information
available, right in your local and school
libraries. Consult natural history periodicals,
including National Geographic, other environmental
journals, and importantly, current world atlases.
Rainforest interest groups may have members in
your area who could serve as an information
resource; also community members may have
travelled to the rainforest, and could offer their
personal observations. Don't overlook the science
section of local video stores and libraries.
Local science museums in your area will also have
information on this topic.
One particular topic recommended to cover is the
rubber tappers who live in the rainforest. A
source for this information is identified in
"Resource Information on Migratory Birds", above,
in General Preparation. Another source is Wilson,
Edward 0., The Diversity of Life, pp. 322-329.
Along with other information presented, be sure to
provide a large map on which American rainforest
areas can be identified.

HOMEWORK TO ASSIGN:
Students assigned the rainforest area will need to
complete their research and make their
presentations in the next class. Students with
other topic areas will have more time to prepare
their presentations, scheduled for Class #7, but
can be encouraged to get started.
FOLLOW-UP: Be available, ideally at identified times, to
assist the students who will be preparing their
rainforest presentations during this week.

Habitat
******************
OBJECTIVE:
Gain an appreciation of the habitat in which
Neotropical migratory birds spend the winter
months.
THEME:
All about the American tropical rainforest, where
many Neotropical migrants spend our winter months.
CLASS
ACTIVITIES:
I.
'Travel' to the American tropical rainforest:
L. Present information about the rainforest and its
inhabitants, including native peoples, focusing on
the topic areas and issues identified for research
in Class #3.
I. Be sure to locate rainforest areas on a map.
PREPARATION:
The teacher will need to collect and organize
materials, unless the students fully take on this
responsibility. Keep in mind that the focus is not
necessarily the birds in the rainforest, but rather an
integrated view of the beauty and uniqueness of the
tropical rainforest environment and habitat.

RESOURCES NEEDED:
See discussion in "Resources" section for Class #3.
HOMEWORK TO ASSIGN:
Have each student write their own thoughts about: Why
would birds want to leave the rainforest and migrate to
North America? Why do birds leave the rainforest?
FOLLOW-UP:
Make note of good resources to use for next year's
class on this topic; return videos and other borrowed

Migration Routes
******************
OBJECTIVE: Gain an appreciation of the long journeys made by
Neotropical migratory birds, and the vast ranges
throughout the Americas that they travel and live
in, when they leave the rainforest.
THEME: Examine migratory routes of a number of birds,
mostly Neotropical.
CLASS
ACTIVITIES:
I. Ask students to share their thoughts from the Homework
assignment from Class #4. Discuss the important
questions raised in the Homework assignment.
II. Learn about migration routes through migration charts:
Examine a sequence of migration charts. For each of
them, discuss:
a. the countries and places each bird spends the
winter;
b. the time when the bird starts migrating
north;
c. how the birds of each species know when to
migrate north?
d. have birds started migrating north yet, this
spring? Which ones?
e. how far north have they reached yet?
5-1
-------
f. what are particular problems the birds face
in flying over specific land areas, or large
expanses of water? (ie. hunters, high
mountain ranges, exhaustion, lack of food,
predators)
g. relate the number of miles the birds are
shown to have travelled on the map to how far
each student has travelled, as discussed in
Class #1.
h. do the students have any ideas as to why
different birds would choose different
migration routes?
i. how do birds know how to find the same route,
year after year?
2. Ask the students to make observations about each
chart, and from comparing the charts (ie. some
routes are shorter than other, some go over land,
while other routes are over water), and take down
all the observations on the blackboard, flip-chart
or overhead projector. Remind the students that
all observations are important, and that is how
field biologists get new ideas and theories.
3. Introduce and explain fully the concept of "Neo-
tropical" migrant, ie. that the bird lives in the
American tropics for at least part of the year.
Contrast this with the Canada Goose (copy of
isochronal chart provided in."Handouts"), which
does migrate in the Americas, but not to the
tropics.
4. Ask the students where the information on the
migration charts comes from. (You may not want to
definitively answer this question, but it is a
useful question to raise, that will be dealt with
in detail in class #9).
PREPARATION:
Copy enough of each of the migratory charts to
allow one per student.
5-2
-------
RESOURCES NEEDED:
Copies of migratory charts are essential. Copies
of several charts, are provided in the "Handouts"
section.
Additionally, the National Geographic map
identified in General Preparation, above (Section
III, Maps) would be an excellent tool for this
class.
HOMEWORK TO ASSIGN:
No specific Homework for this class; students
should continue their research into individual
habitat areas for presentation in Class #7.
FOLLOW-UP:
At some point around this time, the students may break
for spring vacation. Challenge the students to find
and observe birds wherever they may go in their
travels, or even if the students remain right in the
area. Suggest that the vacationing students look to
observe migrating birds. Find out where students may
be going in their travels, and ask them, if they
possibly can, to bring back easily obtainable
information on habitat conditions, particularly those
that may be important to bird survival. Remind them
that this does not need to involve any real expense:
they can make their own observations, take their own
pictures, buy cheap postcards or get free travel
pamphlets. These can fit into the areas of research
for class #7, or students can report on their
observations when they return from vacation.
Remind the students of the first class, and the
difficulties in travel, as they set about on their
individual vacations. Encourage them to think about
the birds beginning to migrate north now, and the
travel challenges they face.

North American Habitats
******************
OBJECTIVE:
Gain appreciation of the diversity of habitats
occupied by the migratory birds (other than the
tropical rainforest habitat) including your local
habitat area, and the particular survival
challenges of each area.
THEME:
Each habitat and ecosystem poses its own different
opportunities and challenges for survival and
success. Habitat areas and ecosystems cross
political boundaries.
CLASS
ACTIVITIES:
I.
Habitat investigations:
A. Present information on the various habitat areas
investigated by the students as the homework
assigned for Class #3. Have the students make
their own presentations, either individually or as
teams. Be sure, during each presentation, to
locate on a map where the area is on one or more
of the migratory bird charts introduced in Class
#5. Focus on the topic areas and issues
identified for research in Class #3.
B. Organize the presentations so they follow a
general northward migratory pattern: Caribbean,
Gulf Coast, Mississippi Basin, Northern United
States, Canada.
C. Discuss differences in the habitats for the birds,
and discuss advantages and disadvantages of each,
7-1
-------
for the birds, and for people. Discuss how birds
and people can accommodate their mutual interests.
Ask students for each habitat area: which of
people's activities there adversely affects the
birds ability to survive there?
D. Identify and discuss the various countries and
states in each habitat and ecosystem area. Focus
on that observation that, in many instances, the
habitat area (also could be called an "ecoregion")
is not confined to political boundaries. What are
the consequences of this to a migratory bird?
PREPARATION:
The teacher will need to collect and organize research
materials for each habitat area, unless the students
fully take on this responsibility.
RESOURCES NEEDED:
See discussion in "Resources" section for Class #3.
HOMEWORK TO ASSIGN:
Ask students to choose, of all the habitat and
ecosystem areas they have learned about, which they
would prefer to live in. They should explain why.
Advise them that, as some birds do, they can choose to
move among areas. They should explain what their
choices are, and why.
Ask students to keep a continuing watch for in-depth
information about local habitat conditions, ecosystems
and land use patterns, such as that occasionally
printed in local newspapers.
FOLLOW-UP:
Monitor local newspapers for interesting articles about
local habitat conditions and land use. These will be
needed for Classes #19 and 21.

class. You could adjust the schedule to allow another
class for this purpose, and make scheduling adjustments
to later classes.

Why and How do Birds
Migrate?
******************
OBJECTIVE: Help students appreciate the importance and depth
of basic scientific questioning and research.
THEME: There is an immense amount that we don't know
about bird migration and the mysteries of natural
systems. First-hand observations by people form
the basis of what we do know.
CLASS
ACTIVITIES:
I. Discuss students' preferences for habitat in the
Homework assigned for Class #7.
II. Conduct Group Survey #1:
Ask the class to think about what they have
learned in the class so far, and as a group to
think of answers to the following:
1. Why do birds migrate?
2. Why do birds leave the rainforest to come to
North America?
3. Given all the problems with the habitat areas
in North America that we have identified in
recent classes, why do migratory birds
continue to come here?
8-1
-------
4. Then, why do birds then leave North America
to go back to South America?
5. What do birds do during the time they spend
the summer in North America?
6. How do birds know when it is time to migrate?
7. How do birds find their way when they are
migrating?
8. What problems do birds have when they are
migrating?
9. How do you, personally, know that birds
migrate?
10. Have you ever seen a bird migrating and
ending up in South or Central America?
11. Where does the information on the migratory
charts examined in previous classes come
from?
12. How and when did bird migration begin?
13. What is the home of migratory birds?
14. What do these birds need to survive?
15. Describe your home.
16. Describe what you need to survive.
Record the various ideas of the students below the
questions. Remember, all sincere ideas are good ones.
When discussing some of these questions, you can
mention that people used to think that when birds
disappeared in the winter the birds had gone to the
moon! The philosopher Aristotle thought that the
birds hid in the local bushes all winter, and
reappeared in the spring. These historic items, as
well as much other interesting information about
migration, are set forth in Migration of Birds.

Migratory Mapping
Purpose
Through this Activity,
students will learn the migra-
tion route of a common
migratory bird, the Canada
goose. This will be done by
compiling and mapping data
from actual band reports,
Learning Outcomes
After completing this Activ-
ity, students will be able to:
A. Map the migration route of
the Canada goose based on
band reports.
B. Define the terms wintering
and breeding grounds.
C. List tw.o uses of band
reports.
D. List the four major flyways
in North America.
Organization
Who: Groups of four
Where: Inside
When: Any time of year
Time: One to two hours
Materials: For the Class

Directions
1. Data Sheet—Page 1 con-
tains 50 banding results. Make
five copies of these band
reports. Cut Data Sheets into
250 strips and put these into a
hat or paper bag. Note: These
band reports are simplified ver-
sions of rea1 data that have
been turned in to the U.S. Fish
and Wildlife Service.
2. Lead students in a discu:
sion of bird banding. Bandir
is done to provide informatn
regarding migratory birds'
routes. Through recovery of
bird bands, data on directio
and duration of migration i?
tained. Introduce students t
the idea of flyways, which i
generalized migratory cornc
Although species' actual mi
tions do not strictly conforr
with these flyways, they are
useful way of generalizing
migration routes. Band
recoveries help to indicate
along which flyways birds
migrate. (For instance, the
Canada goose migrates alo
all four flyways.) Use the
Poster-Side 2 and the pock
map to illustrate the idea a

sent to them regarding the
locations of banded Canada
geese. Their job is to map
Canada goose migration-
spring and fall—based on the
reports. Tell students they will
each receive data from seven
or eight bands. While bands
are recovered year round, the
information students receive
will be mainly from summer
and from fall migration periods.
(Have the students suggest
why more bands might be re-
covered at these times of the
year.) Students can tell the dif-
ference by the dates: spring
migrations generally occur be-
tween February and April and
fall migrations between
September and December.
Reports from January, May,
June. July, and August indicate
non-migrating times of the
year. During the summer
months geese are at their
breeding grounds; during
January they are wintering in
more southern areas. Tell
students they will plot reports
on the maps they have been
given. They should use dif-
ferent colors for migration
dates, and for dates indicating
presence on wintering and
breeding grounds.
Completed student map
5. Pass the hat around the
classroom. Each student should
take one strip (band result) and
mark the date on the map in the
correct location. Pass the band-
ing reports around again, and
continue this until each student
has received at least seven
reports. If students receive two
of the same result, they should
plot both.
6. Have students form groups
of four to compare data. Stu-
dents should map the banding
reports of the other group
members. Based on the addi-
tional information, have stu-
dents plot spring and fall
migration routes based on the
U.S. flyways and indicate
generalized wintering and
breeding grounds. Their data
will indicate that the Canada
geese used in this Activity
breed mostly in Canada. They
migrate along either the Missis-
sippi Flyway or the Atlantic
Flyway. Therefore, the routes
mapped can cover most of the
States north of South Carolina
and east of Wyoming.
-------
7. If possible, make an enlarge-
ment of the Data Sheet map
and plot all the band reports.
Ask students where band
report #1 was from and if the
bird was recovered during the
spring or fall migration. Plot
each migration period in a dif-
ferent color. Continue collect-
ing information from the class
and plotting it until all reports
have been shown.
8. Have students pick one of
the flyways and research its
geography. Generate a class
list of possible problem areas
and favorable habitats (refuges.
rivers) which Canada geese
might encounter on that route.
Followup
Through research and
observations made throughout
the school year, students can
note the varying numbers,
types, and varieties of birds in
the area and determine which
species migrate and which do
not. They can then study one
migratory species they have
identified in the neighborhood
and use a map and bird guides
to examine where the species
migrates. Research should in-
clude the route and timing of
migration, obstacles en-
countered, and traditional
habitats used during migration.
If possible, have a local
conservation officer or Fish
and Wildlife Service employee
bring in samples of actual bird
bands and mounted birds with
bands to discuss banding in
greater detail. Have the
speaker tell students what they
should do if they see a band on
a bird (either live or dead).
Some wildlife refuges allow
students to observe banding
operations and on occasion
will allow upper-level students
to participate.

D
Canada geese migrate in a V-formation at
about 50 mph. Their movement is steady and
unhurried and closely follows the movement of
the seasons.
Canada geese are often banded by scientists to
obtain information about their migrations.
Canada geese make their spring migrations
(south to north) from about February to April.
Fall migrations (north to south) occur from
about September to December.

How Do You Know
Migration Occurs?
OBJECTIVE: Help students appreciate the importance and depth
of basic scientific questioning and research.
THEME: There is an immense amount that we don't know
about bird migration, and first-hand observations
by people form the basis of what we do know.
CLASS
ACTIVITIES:
I. Mapping Migration Patterns:
Use the referenced group exercise in "Resources
Needed", below, to have students learn 'first hand' how
we find out about bird migration, and about the
problems birds face along the way.
More than one class period will be needed for this
complete exercise. It can be started during this class
period, and completed during the next class. It works
well to get it organized and started during one class,
and then students will be ready to begin right in on it
and complete it in the next class.
PREPARATION:
For the mapping exercise, a large map of North America
is needed. The migration information (provided in
"Resources Needed", below) should be cut into strips
ahead of time, and the teacher should bring a hat or
8-4
-------
another container to the class into which the slips can
be placed.
RESOURCES NEEDED:
The needed excerpts from Migratory Birds Issue Pac.
Activity #2, Migratory Mapping (U.S. Fish and Wildlife
Service, 1992) are included with the Course Handouts.
This packet contains an interesting exercise of mapping
of the migration of Canada Geese. This exercise is
only part of a larger comprehensive packet, that could
be ordered in its entirety. See "Course Logistics",
above, for ordering information.
The teacher will need to bring a large map (preferably
mounted, for ease of working), marking pens, and a hat
or other container.
HOMEWORK TO ASSIGN:
One creative assignment could be for students to
brainstorm and identify other possible ways that people
could find out specific facts about bird migrations.
For example, the New York Times reports in "New
Technique May Clear Up Mystery of Vanishing Songbird"
that chemicals in feathers may help trace birds to
winter grounds (New York Times, May 31, 1994, p. C4) .
Students could come up with a variety of other ideas,
too.
FOLLOW-UP:
No specific follow-up is needed.

Class #10
How to Identify Birds
******************
OBJECTIVE: Learn the basics of how to recognize birds, in
preparation for interesting and rewarding trips of
field observation.
THEME: Identify basics of bird observation.
CLASS
ACTIVITIES:
I. Depict the basic features of birds that will be helpful
for students to know in the field:
1. Ask the students to draw an outline of a bird on a
clean sheet of paper, and to mark on it the
identification features that they already could
recognize (ie. beak, tail, etc.) Spend only about
five minutes on this.
2. Using the blackboard, overhead projector or large
drawing pad, sketch out the outline of a bird, and
mark the key features of the bird, particularly
those that are helpful to field observation.
For reference, use a standard chart depicted in
the front of a bird identification book. See
"Field Guides", in General Preparation, above).
Have the students copy the chart and the
identification names and markings as you go along.
3. Collect the students papers, hand them a blank
paper, and challenge them to write from memory a
bird outline and as many of the markings as they
10-1
-------
can remember.
4. After #3 is attempted, hand the students back
their original notes, and ask them to complete
those things on their second sheet that they could
not remember.
Note: this is not meant to be a graded exercise,
but rather a little short-term memory reinforcing
trick for trying to remember as much as possible.
Explain this to the students. They won't remember
all the markings anyway, but they will remember
some of them when you get out into the field, and
at least they will be familiar with the standard
marking names, such as 'crown' or 'wing-bar', that
otherwise they have never heard before.
II. Finalize field trip logistics:
The bird identification activity should be
completed in enough time to discuss the final
plans for the field trips: exact logistics of
where and when to meet, contingency plans related
to the weather or other individual student
activities (such as school orchestra, play
rehearsals, tests, etc.), appropriate field gear,
including pants, boots and hats, and arranging for
bird identification books and binoculars.
If enough time is available, the students can be
asked to find the location of the field trips on a
local map.
PREPARATION:
Obtain a diagram of bird identification features
from the introductory sections of your bird
identification field guide. Review the diagram
so that you will be familiar with it.
RESOURCES NEEDED:
1. Reference for bird identification marks, for
the teacher to copy from;
2. Paper for each student, pencils, blackboard,
overhead projector or large marker board;
10-2
-------
3. Printed information sheets concerning the
logistics and details of the field trips;
4. Local area map for pinpointing field trip
locations.
HOMEWORK TO ASSIGN:
No specific Homework for this class.
FOLLOW-UP:
Make adjustments and final preparations for the
field trips.

Class #11
Discovering Diversity
******************
OBJECTIVE: Have students begin to discover for themselves the
incredible diversity of life, as reflected in the
many different types of birds.
THEME: The rich variety of bird life is fascinating for
those who explore it .
CLASS
ACTIVITY:
This class period is designed to consist primarily of
unstructured individual exploration of a major bird
field guide. The students, either individually or in
teams of two, should be handed a bird field guide, and
told they will have the class period to explore it.
This can be a very successful and fascinating exercise,
because the diverse depictions of birds, and
comparisons among them, are probably something that the
students have never taken the time to explore before.
The variety of bird life is itself amazing and
extraordinary.
At first, the students may be a little sheepish about
exploring the guides, but allow them enough time to
really get started.
If necessary, the class can be prompted by challenges
to find their favorite bird, or to try to locate birds
that they have seen before, and read about them.
Additionally, they can be challenged to find different
types of features about birds, particularly their
bills, and obviously their plumage. As the class to
start thinking about why do birds have so many
11-1
-------
different color feathers and types of bills?
Challenge the students also to find important features
about the books, such as: how the index works; how the
guide is organized; and the migratory mapping feature,
and how to find the right map.
Be careful not to overwhelm the students with too much
lecture at this time. They should be given enough time
to explore the book productively themselves, without
rushing. Features of the book that aren't covered
during this class can be discussed during a field trip.
Discovering the diversity of bird life can be a good
introduction to prompt the class the think about the
importance and beauty of diversity in all forms of
life.
Note: be sure to confirm the final details of a field
trip, if it is planned for the next class. Remind the
students to bring their field guides, if they have
their own individual copies.
PREPARATION:
Obtain bird field guides.
RESOURCES NEEDED:
Obtain as many field guides as possible. (See
discussion in Course Logistics, above, concerning
selection of field guides). Ideally, there will be one
identical field guide per student. However, this is
not necessary, and students can be asked to share. If
field guides are not identical, be sure to observe this
and be prepared to help students in the field to locate
birds in their particular guide.
HOMEWORK TO ASSIGN:
Ask the students to think and write about:
1. Why do birds have so many different color
feathers?
2. Why do birds have different shapes and types of
11-2
-------
bills?
3. What would the world be like if all the birds
looked the same?
If the students have individual copies of the books,
they can be asked to look through the books again, as
much as possible, at their leisure.
FOLLOW-UP:
Collect field guides, unless they belong to the
students, and bring them to next weeks' field trip.

Field Trip
******************
OBJECTIVE:
Have students observe and begin to appreciate
natural ecosystems and biodiversity first-
hand, through direct observations of birds in
their natural surroundings.
THEME:
Explore a local area to discover the
diversity of birds there, and find out about
the types of ecosystems in which birds live.
CLASS
ACTIVITY:
I.
Field trip to local area to observe birds and our
habitat. See in-depth discussion in Course Logistics,
above.
In the field, help students learn field identification
and observation techniques, including focusing on where
particular birds are found (forest, field, wetland,
suburban yard); behavior of the birds, and field
markings (using identification techniques introduced in
Class #10). Lead students to appreciate the wonderful
variety of colors in the different birds they are
seeing.
Also, it is important to focus on other components of
the particular ecosystem visited. This can be done,
for example, by finding out about the type of food
eaten by the various birds, by observing their type of
bill. Field identification of different types of bills
is introduced in standard field guides, such as Birds.
(Peterson, 4th ed), at p. 34. Focusing on the bills
and the type of food eaten by each bird in the wild is
12-1
-------
a key concept in helping to understand the importance
of each bird in the natural cycles, and in observing
other life forms of the particular ecosystem. Lead
students to appreciate the rich variety of life and
color throughout the ecosystem, using the birds as a
focal point.
II. Record any birds observed on the students' individual
life list.
III. Find out and discuss other areas in the Americas where
the birds you have observed live. For example, for
each bird observed, find out where it spends the winter
months, and find out whether the bird is migrating
through your area to a certain more northern territory,
or is establishing itself in your locality for the
summer. The bird field guides can be a start to this.
The National Geographic map referenced in General
Preparation. Maps (III), can be a very valuable tool
for referencing migratory routes of birds observed.
Students may have to do more research on this, which
can be their homework for each field trip class. For
each field trip class, locate on a map of the Americas
the winter home of each type of bird observed, and its
summer location. You can do this as each bird is
observed, if you have the information available, or as
a focused segment of each field trip class, using the
homework research that the students have done.
When identifying the various areas, be sure to remember
and discuss highlights of the individual habitat
explorations from Classes #4 and #7.
PREPARATION:
See in-depth discussion under "Course Logistics",
above.
RESOURCES NEEDED:
Field guides and binoculars. See in-depth discussion
under "Course Logistics", above.
Map(s) to mark on.

-------
HOMEWORK TO ASSIGN:
1. For each field trip, ask students to record their
key first-hand observations about birds and
habitat areas in a note-book. Encourage them to
write about the things that they personally find
interesting on the field trip. Explain that
scientists need to record observations directly in
the field as they are occurring, but that a daily
journal can be useful as well.
2. As necessary, research the locations of the winter
and summer territories of the birds observed in
that class. Each student can be assigned to find
out about one bird that was observed, and the
findings can be shared with the class and plotted
on a map during the next class.
3. Read and become familiar with a Glossary of Words
the students will need to at least recognize in
order to read the Homework to be assigned in Class
#14.
FOLLOW-UP:
Write thank-you notes to any guest field leaders, or
owners of the natural areas you have visited.

biodiversity The variety of organisms considered at all levels,
from genetic variants belonging to the same species through
arrays of species to arrays of genera, families, and still higher
taxonomic levels; includes the variety of ecosystems, which
comprise both the communities of organisms within particular
habitats and the physical conditions under which they live.
biological diversity See biodiversity
biomass The total weight (usually, dry weight) of a designated
group of organisms in a particular area, as of all the birds
living in a woodlot or all the algae in a pond or all the
organisms in the world.
bioxne A major category of habitat in a particular region of the
world, such as the tundra of northern Canada or the rain forest
of the Amazon basin.
bioregion A continuous natural area, such as a river system or
mountain range, large enough to extend beyond political
boundaries.
biota The combined flora, fauna, and microorganisms of a given
region.
diversity See Modi varsity
DNA Deoxyribonucleic acid. The fundamental hereditary material
of all living organisms; the polymer composing the genes.
ecosystem The organisms living in a particular environment, such
as a lake or a forest (or, in increasing scale, an ocean or the
whole planet), and the physical part of the environment that
impinges on them. The organisms alone are called the community.
endangered Near extinction. Referring to a species or ecosystem
-------
so reduced or fragile that it is doomed or at least fatally
vulnerable.
endemic A species or race native to a particular place and found
only there.
environment The surroundings of an organism or a species: the
ecosystem in which it lives, including both the physical
environment and the other organisms with which it comes in
contact.
equilibrium See species equilibrium.
extinction The termination of a ny lineage of organisms, from
subspecies to species and higher taxonomic categories from genera
to phyla. Extinction can be local, in which one or more
populations of a species or other unit vanish but others survive
elsewhere, or total (global), in which all the populations
vanish. When biologists speak of the extinction of a particular
species without further qualification, they mean total
extinction.
extractive reserve A wild habitat from which timber, latex, and
other natural products are taken on a sustained yield basis with
minimal environmental damage and, ideally, without the extinction
of native species.
fauna All the animals found in a particular place.
flora All the plants found in a particular place.
habitat An environment of a particular kind, such as lake shores
or tall-grass prairie; also a particular environment in one
place, such as the mountain forest of Tahiti.
keystone species A species, such as the sea otter, that affects
the survival and abundance of many other species in the community
in which it lives. Its removal or addition results in a
relatively significant shift in the composition of the community
and sometimes even in the physical structure of the environment.
species The basic unit of classification, consisting of a
population or series of populations of closely related and
similar organisms. In sexually reproducing organisms, the
species is more narrowly defined by the biological-species
concept: a population or series of populations of organisms that
freely interbreed with one another in natural conditions but not
with members of other species.
species equilibrium The steady-state number of species, or
biodiversity, found on an island or isolated patch of habitat due
to a balance between the immigration of new species and the
extinction of old residents.
-------
symbiosis The living together of two or more species in a
prolonged and intimate ecological relationship, such as the
incorporation of algae and cyanobacteria within fungi to create
lichens.
systematics The scientific study of the diversity of life.
Sometimes used synonymously with taxonomy to mean the procedures
of pure classification and reconstruction of phylogeny
(relationship among species); on other occasions it is used more
broadly to cover all aspects of the origins and content of
biodiversity.
taxonomy The science (and art) of the classification of
organisms. See also systematics.

CHAPTER FOURTEEN
Resolution
EVERY COUNTRY has three forms of wealth: material, cul-
tural, and biological. The first two we understand well
because they are the substance of our everyday lives. The es-
sence of the biodiversity problem is that biological wealth is
taken much less seriously. This is a major strategic error, one
that will be increasingly regretted as time passes. Diversity is a
potential source for immense untapped material wealth in the
form of food, medicine, and amenities. The fauna and flora are
also parf of a country's heritage, the product of millions of years
of evolution centered on that rime and place and hence as much
a reason for national concern as the particularities of language
and culture.
The biological wealth of the world is passing through a bot-
tleneck destined to last another fifty yean or more. The human
population has moved past 5.4 billion, is projected to reach 8.5
billion by 2025, and may level off at 10 to 15 billion by midcen-
tury. With such a phenomenal increase in human biomass, with
material and energy demands of the developing countries ac-
celerating at an even faster pace, far less room will be left for
most of the species of plants and animals in a short period of
time.
The human juggernaut creates a problem of epic dimensions:
how to pass through the bottleneck and reach midcenrury with
the least possible loss of biodiversity and the least possible cost
to humanity. In theory at least, the minimization of extinction
rates and the minimization of economic costs are compatible:
3JI
-------
the more that other forms of life are used and saved, the more
productive and secure will our own species be. Future generations
will reap the benefit of wise decisions taken on behalf of biological
diversity by our generation.
What is urgently needed is knowledge and a practical ethic based
on a time scale longer than we are accustomed to apply. An ideal
ethic is a set of rules invented to address problems so complex or
stretching so far into the future as to place their solution beyond
ordinary discourse. Environmental problems are innately ethical.
They require vision reaching simultaneously into the short and long
reaches of time. What is good for individuals and societies at this
moment might easily sour ten years hence, and what seems ideal
over the next several decades could ruin future generations. To
choose what is best for both the near and distant futures is a hard
task, often seemingly contradictory and requiring knowledge and
ethical codes which for the most part are still unwritten.
If it is granted that biodiversity is at high risk, what is to be done?
Even now, with the problem only beginning to come into focus, there
is little doubt about what needs to be done. The solution will require
cooperation among professions long separated by academic and prac-
tical tradition. Biology, anthropology, economics, agriculture, gov-
ernment, and law will have to find a common voice. Their conjunc-
tion has already given rise to a new discipline, biodiversity studies,
defined as the systematic study of the full array of organic diversity
and the origin of that diversity, together with the methods by which
it can be maintained and used for the benefit of humanity. The
enterprise of biodiversity studies is thus both scientific, a branch of
pure biology, and applied, a branch of biotechnology and the social
sciences. It draws from biology at the level of whole organisms and
populations in the same way that biomedical studies draw from
biology at the level of the cell and molecule. Where biomedical stud-
ies are concerned with the health of the individual person, biodiver-
sity studies are concerned with the health of the living part of the
planet and its suitability for the human species. What follows, then,
is an agenda on which I believe most of those who have focused on
biodiversity might agree. All the enterprises I will list are directed at
the same goal: to save and use in perpetuity as much of earth's
diversity as possible.
1. Survey the world's fauna and flora. In approaching diversity, biol-
ogists are close to traveling blind. They have only the faintest idea
332 The Human Impact
-------
of how many species there are on earth or where most occur; the
biology of more than 99 percent remain unknown. Systematists are
aware of the urgency of the problem but far from agreed on the best
way to solve it. Some have recommended the initiation of a global
survey, aimed at the discovery and classification of all species. Oth-
ers, sensibly noting the shortage of personnel, funds, and time, think
the only realistic hope lies in the rapid recognition of the threatened
habitats that contain the largest number of endangered endemic
species (the hot spots).
In order to move systematics into the larger role demanded by the
extinction crisis, its practitioners have to agree on an explicit mission
with a timetable and cost estimates. The strategy most likely to work
is mixed, aiming at a complete inventory of the world's species, but
across fifty years and at several levels, or scales in time and space,
from hot-spot identification to global survey, audited and readjusted
at ten-year intervals. As each decade comes to a close, progress to
that point could be assessed and new directions identified. Emphasis
from the outset would be placed on the hottest spots known or
suspected.
Three levels can be envisioned. The first is the RAP approach, from
the prototypic Rapid Assessment Program created by Conservation
International, a Washington-based group devoted to the preservation
of global biodiversity. The purpose is to investigate quickly, within
several years, poorly known ecosystems that might be local hot spots,
in order to make emergency recommendations for further study and
action. The area targeted is limited in extent, such as a single valley
or isolated mountain. Because so little is known of classification of
the vast majority of organisms and so few specialists are available to
conduct further studies, it is nearly impossible to catalog the entire
fauna and flora of even a small endangered habitat. Instead a RAP
team is formed of experts on what can be called the elite focal
groups—organisms, such as flowering plants, reptiles, mammals,
birds, fishes, and butterflies, that are well enough known to be
inventoried immediately and can thereby serve as proxies for the
whole biota around them.
The next level of inventory is the BIOTROP approach, from the
Neotropical Biological Diversity Program of the University of Kansas
and a consortium of other North American universities formed in
the late 1980s. Instead of pinpointing brushfires of extinction at se-
lected localities in the RAP manner, BIOTROP explores more system-
atically across broad areas believed to be major hot spots or at least
Resolution 313
-------
to contain multiple hot spots. Examples of such regions include the
eastern slopes of the Andes and the scattered forests of Guatemala
and southern Mexico. Beyond identifying critical localities, the larger
goal is to set up research stations across the area that embrace dif-
ferent latitudes and elevations. The work begins with a few focal
organisms. It expands to less familiar groups, such as ants, beetles,
and fungi, as enough specimens are collected and experts in the
groups are recruited to study them. In time, close studies of rainfall,
temperature, and other properties of the environment are added to
the species inventory. The most important and best equipped of the
stations are likely then to evolve into centers of long-term biological
research, with leadership roles taken by scientists from the host
countries. They can also be used to train scientists from different
parts of the world.
We now come to the third and highest stage of the biodiversity
survey. From inventories at the RAP and BIOTROP levels in different
parts of the world, accompanied by monographic studies of one
group of organisms after another, the description of the living world
will gradually coalesce to create a fine-grained image of global bio-
diversity. The growth of knowledge will inevitably accelerate, even
given a constant level of effort, by producing its own economies of
scale. Costs per species logged into the inventory fall as new methods
of collecting and distributing specimens are devised and procedures
for accessing information are improved. Costs are not simply additive
when nonelite groups of organisms are included, but instead decline
on a per-species basis. Botanists, for example, can collect insects
living on the plants they study, while identifying these hosts for the
entomologists, and entomologists can run the procedure in reverse,
gathering plant specimens in company with the insects they collect.
Groups such as reptiles, beetles, and spiders can be sampled across
entire habitats, then distributed to specialists on each group in turn.
As biodiversity surveys proceed at the several levels, the knowl-
edge gathered becomes an ever more powerful magnet for other
kinds of science. Field guides and illustrated treatises open doors to
the imagination, and networks of technical information draw geolo-
gists, geneticists, biochemists, and others into the enterprise. It will
be logical to gather much of the activity into biodiversity centers,
where data are gathered and new inquiries planned. The prototype
is Costa Rica's National Institute of Biodiversity (Instituto Nacional
de Biodiversidad), INBio for short, established on the outskirts of the
capital city of San JosŁ in 1989 The aim of INBio is nothing less than
314 The Human Impact
-------
to account for all the plants and animals of this small Central Amer-
ican country, over half a million species in number, and to use the
information to improve Costa Rica's environment and economy. It is
perhaps odd that a developing nation should lead the way in such
a concerted scientific enterprise, but others will follow. Detailed dis-
tribution maps of plants and many kinds of animals have been drawn
up in Great Britain, Sweden, Germany, and other European countries
under governmental and private auspices. As I write, plans for a
national biodiversity center in the United States have been advanced
by the Smithsonian Institution and are under wide discussion. En-
abling legislation has been placed before Congress but is not yet
passed.
The national center of the United States will not have to start from
scratch. Many kinds of organisms have been already carefully studied
and mapped. Several of the states, including Massachusetts and
Minnesota, have undertaken programs to locate endangered species
of plants and vertebrate animals within their borders. For fifteen
years the Nature Conservancy, one of the premier private American
foundations, has conducted a similar effort across all the states. The
operation, setting up Natural Heritage Data Centers, has recently
been extended to fourteen Latin American and Caribbean countries.
Another key element of biodiversity studies at all levels will be
microgeography, the mapping of the structure of the ecosystem in
sufficiently fine detail to estimate the populations of individual spe-
cies and the conditions under which they grow and reproduce. A
working technology already exists in the form of Geographic Infor-
mation Systems, a collection of layers of data on topography, vege-
tation, soils, hydrology, and species distributions that are registered
electronically to a common coordinate system. When applied to bio-
diversity and endangered species, the cartography is called gap anal-
ysis. Even though incomplete, gap analysis can reveal the effective-
ness of existing parks and reserves. It can be used to help answer
the larger questions of conservation practice. Do protected areas in
fact embrace the largest possible number of endemic species? Are
the surviving habitat fragments large enough to sustain the popula-
tions indefinitely? And what is the most cost-effective plan for further
land acquisition?
The same information can be used to zone large regions. Parcels
of land will have to be set aside as inviolate preserves. Others will
be identified as the best sites for extractive reserves, for buffer zones
used in part-time agriculture and restricted hunting, and for land

316 The Human Impact
-------
convertible totally to human use. In the expanded enterprise, land-
scape design will play a decisive role. Where environments have
been mostly humanized, biological diversity can still be sustained at
high levels by the ingenious placement of woodlots, hedgerows,
watersheds, reservoirs, and artificial ponds and lakes. Master plans
will meld not just economic efficiency and beauty but also the pres-
ervation of species and races.
The layered data can further aid in defining "bioregions," areas
such as watersheds and forest tracts that unite common ecosystems
but often extend across the borders of municipalities, states, or even
countries. A river may make economic or military sense in dividing
two political units, but it makes no sense at all in organizing land-
use management. Bioregionalism has had a long but inconclusive
history within the United States. It dates back at least as far as John
Muir's successful championing of national parks and the establish-
ment of the national forest system in 1891. Since the 1930s it has
received increasing governmental sanctions with variable specific
agendas, from the Tennessee Valley Authority, which managed land
and created hydroelectric power through a large part of the south-
east, to the establishment of the Appalachian National Scenic Trail,
federal and state management of the south Florida water system and
the Everglades, and the multiple regulatory and promotional activi-
ties of the New England River Basins Commission during its tenure
from 1967 to 1981.
Other examples of bioregionalism abound in the United Sates, but
it cannot be said that the movement has coalesced around any single
philosophy of land management. Nor has the preservation of biodi-
versity ranked as more than an auxiliary goal. In fact the great dams
built by the Tennessee Valley Authority, while providing cheap elec-
tric power to an impoverished part of the nation, inadvertently wiped
out a substantial part of the native river fauna. The lower priority
given diversity has not been by deliberation but from incomplete
knowledge of the faunas and floras of the affected regions.
Systematics, having emerged as a prerequisite for effective long-
term zoning and bioregionalism, is a labor-intensive enterprise. Sci-
entists who study the classification of particular organisms, such as
centipedes and ferns, are often by default the only authorities on the
general biology of those organisms. About 4,000 such specialists in
the United States and Canada attempt to manage the classification
of the many thousand species of animals, plants, and microorganisms
living on the continent. To varying degree they are also responsible
Resolution 317
-------
for the millions of species occurring elsewhere in the world, since
even fewer systematists are active in other countries. Probably a
maximum of 1,500 trained professional systematists are competent
to deal with tropical organisms, or more than half of the world's
biodiversity. A typical case is the shortage of experts on termites,
which are premier decomposers of wood, rivals of earthworms as
turners of the soil, owners of 10 percent of the animal biomass in the
tropics, and among the most destructive of all insect pests. There are
exactly three people qualified to deal with termite classification on a
worldwide basis. A second revealing case: the oribatid mites, tiny
creatures resembling a cross between a spider and a tortoise, are
among the most abundant animals of the soil. They are major con-
sumers of humus and fungus spores, and therefore key elements of
land ecosystems almost everywhere. In North America only one
expert attends to their classification on a full-time basis.
With so few people prepared to launch it, a complete survey of
earth's vast reserves of biological diversity may seem beyond reach.
But compared with what has been dared and achieved in high-energy
physics, molecular genetics, and other branches of big science, the
magnitude of its challenge is not all that great. The processing of 10
million species is achievable within fifty years, even with the least
efficient, old-fashioned methods. If one systematist proceeded at the
cautious pace of ten species per year, including field trips for col-
lecting, analysis of specimens in the laboratory, and publication,
taking time out for vacations and family, about one million person-
years of work would be required. Given forty years of productive
life per scientist, the effort would consume 25,000 professional life-
times. The number of systematists would still represent less than 10
percent of the current population of scientists active in the United
States alone, and it falls well short of the number of enlisted men in
the standing armed forces of Mongolia, not to mention the trade and
retail personnel of Hinds County, Mississippi. The volumes of pub-
lished work, one page per species, would fill 12 percent of the shelves
of the library of Harvard's Museum of Comparative Zoology, one of
the larger institutions devoted to systernatics.
I have based these estimates on what is the least efficient procedure
imaginable, in order to establish the plausibility of a total inventory
of global biodiversity. Systematic work can be speeded up many
times over by new techniques now coming into general use. The
Statistical Analysis System (SAS), a set of computer programs already
running in several thousand institutions worldwide, records taxo-
318 The Human Impact
-------
nomic identifications and localities of individual specimens and au-
tomatically integrates data in catalogs and maps Other computer-
aided techniques compare species automatically across large numbers
of traits, applying unbiased measures of similarity, the procedure
called phenetics. Still others assist in deducing the most likely family
trees of species, the method called cladistics. Scanning-electron micros-
copy has accelerated the illustration of insects and other small or-
ganisms. Computer technology will in time include image scanning
that can identity species instantly while flagging specimens that be-
long to new species. Biologists are also close to electronic publication,
which will allow retrieval of descriptions and analyses of particular
groups of organisms by desktop personal computers.
Every other form of biological information on species—ecology,
physiology, economic uses, status as vectors, parasites, agricultural
pests—can be layered in the databases. DNA and RNA sequences and
gene maps can be added. GenBank, the genetic-sequence bank, has
been chartered to provide a computer database for all known DNA
and RNA sequences and related biological information. By 1990 it
had accumulated 35 million sequences distributed through 1,200 spe-
cies of plants, animals, and microorganisms. The rate of data acces-
sion is ascending swiftly with the advent of improved sequencing
methods.
2. Create biological wealth. As species inventories expand, they open
the way n> bioeconomic analysis, the broad assessment of the eco-
nomic potential of entire ecosystems. Every community of organisms
contains species with potential commodity value—timber and wild-
plant products to be harvested on a sustained basis, seeds and
cuttings that can be transplanted to grow crops and ornamentals
elsewhere, fungi and microorganisms to be cultured as sources of
medicinals, organisms of all kinds offering new scientific knowledge
that points to still more practical applications. And the wild habitats
have recreational value, which will grow as a larger sector of the
public travels and learns to enjoy natural history.
The decision to make bioeconomic analysis a routine part of land-
management policy will protect ecosystems by assigning them future
value. It can buy time against the removal of entire communities of
organisms ignorantly assumed to lack such value. When local faunas
and floras are better known, the decision can be taken on how to
use them optimally—whether to protect them, to extract products
from them on a sustainable yield basis, or to destroy their habitat for
Resolution 319
-------
full human occupation. Destruction is anathema to conservationists,
but the fact remains that most people, lacking knowledge, regard it
as perfectly acceptable. Somehow knowledge and reason must be
made to intrude. 1 am willing to gamble that familiarity will save
ecosystems, because bioeconomic and aesthetic values grow as each
constituent species is examined in turn—and so will sentiment in
favor of preservation. The wise procedure is for law to delay, science
to evaluate, and familiarity to preserve. There is an implicit principle
of human behavior important to conservation: the better an ecosystem
is known, the less likely it will be destroyed. As the Senegalese conser-
vationist Baba Dioum has said, "In the end, we will conserve only
what we love, we will love only what we understand, we will un-
derstand only what we are taught."
A key enterprise in bioeconomic analysis is what Thomas Eisner
has called chemical prospecting, the search among wild species for new
medicines and other useful chemical products. The logic of pros-
pecting is supported by everything we have learned about organic
evolution. Each species has evolved to become a unique chemical
factory, producing substances that allow it to survive in an unforgiv-
ing world. A newly discovered species of roundworm might produce
an antibiotic of extraordinary power, an unnamed moth a substance
that blocks viruses in a manner never guessed by molecular biolo-
gists. A symbiotic fungus cultured from the rootlets of a nearly extinct
tree might yield a novel class of growth promoters for plants. An
obscure herb could be the source of a sure-fire blackfly repellent—at
last. Millions of years of testing by natural selection have made
organisms chemists of superhuman skill, champions at defeating
most of the kinds of biological problems that undermine human
health.
Because chemical prospecting depends so heavily on classification,
it is best conducted in tandem with biodiversity surveys. In order to
succeed, investigators must also work in laboratories equipped with
advanced facilities, which are usually available only in industrialized
countries. In 1991 Merck and Company, the world's largest phar-
maceutical firm, agreed to pay Costa Rica's National Institute of
Biodiversity $1 million to assist in such a screening effort. The insti-
tute will collect and identify the organisms, sending chemical samples
from the most promising species to the Merck laboratories for me-
dicinal assay. If natural substances are marketed, the company is
committed to pay the Costa Rican government a share of the royal-
ties, which will then be earmarked for conservation programs. Merck
has previously marketed four drugs from soil organisms originating
320 The Human Impact
-------
from other countries. One, derived from a fungus, is Mevacor, an
effective agent for lowering cholesterol levels. In 1990 Merck sold
$735 million worth of this substance alone. It follows that a single
success in Costa Rica—a commercial product from, say, any one
species among the 12,000 plants and 300,000 insects estimated to live
in the country—could handsomely repay Merck's entire investment.
There are historical reasons why Merck and other research and
commercial organizations are increasingly inclined to take on chem-
ical prospecting. The search for naturally occurring drugs and other
chemical products has been cyclical through the years. In the 1960s
and 1970s pharmaceutical companies phased out the screening of
plants on the grounds that it was too complicated and expensive.
With only one in 10,000 species yielding a promising substance (by
procedures then in use) and millions of dollars needed to bring a
product fully on line, the eventual payoff seemed marginal. The
companies turned to new technologies in microbiology and synthetic
chemistry, hoping to design the magic bullets of the new medical
age with chemicals taken from the shelf. To rely on human ingenuity
rather than evolved natural chemistry in distant jungles seemed
much more "scientific" and direct, and perhaps less expensive. Yet
natural products remained a potential shortcut, a Columbus-like jour-
ney west, for those willing to acquire the essential skills. Now the
pendulum has begun to swing back, again from advances in tech-
nology, because high-volume, robot-controlled biological assays al-
low larger companies to screen up to 50,000 samples a year using
only bits of fresh tissue or extract flown to them from any part of
the world.
The path from wild organism to commercial production can some-
times be shortened further by taking clues from the lore and tradi-
tional medicine of indigenous peoples. It is a remarkable fact that of
the 119 known pure pharmaceutical compounds used somewhere in
the world, 88 were discovered through leads from traditional medi-
cine. The knowledge of all the world's indigenous cultures, if gath-
ered and catalogued, would constitute a library of Alexandrian pro-
portions. The Chinese, for example, employ materials from about
6,000 of the 30,000 plant species in their country for medicinal pur-
poses. Among them is artemisinin, a terpene derived from the annual
wormwood (Artemisia annua), which shows promise as an alternative
to quinine in the treatment of malaria. Because the molecular struc-
tures of the two substances are entirely different, artemisinin would
have been discovered much less quickly if not for its folkloric repu-
tation.
Resolution 321
-------
Because the lives of people and the reputations of shamans have
depended on it for generations, much of the traditional pharmaco-
poeia is reliable. Extraction procedures and dosage have been tested
by trial and error countless times. But this preliterate knowledge,
like so many of the plant and animal species to which it pertains, is
disappearing rapidly as tribes move from their homelands onto farms
and into cities and villages. When they take up new trades, their
languages fall into disuse and the old ways are forgotten. During the
1980s, all but 500 of the 10,000 Penans of Borneo abandoned their
centuries-old seminomadic life in the forests and settled in villages.
Today their memories are fading quickly. Eugene Linden notes, "Vil-
lagers know that their elders used to watch for the appearance of a
certain butterfly, which always seemed to herald the arrival of a
herd of boar and the promise of good hunting. These days, most of
the Penans cannot remember which butterfly to look for." On the
other side of the world, 90 of Brazil's 270 Indian tribes have vanished
since 1900, and two thirds of those remaining contain populations of
less than a thousand. Many have lost their lands and are forgetting
their cultures.
Small farms around the world are giving way to the monocultures
of agrotechnology. The raised garden squares of the Incas have all
but vanished; the densely variegated gardens of Mesoamerica and
West Africa are threatened. The revitalization of local farming is
another aim of biodiversity studies. The goal is to make the practice
more economically practical, while conserving the genetic reserves
that will contribute to crops of the future. Species and strains of high
economic efficiency, from perennial com to amaranth and iguanas,
can be fed through research centers into the local regions best suited
to use them. A successful prototype of such enterprises is the Tropical
Agricultural Research and Training Center (CAT1E) at Turrialba, Costa
Rica. Created by the Organization of American States in 1942, CATIE
maintains large samples of plant species, including disease-resistant
strains of cacao and other tropical crops Its staff members experiment
with propagation methods for crops and timber, design wildland
preservation programs, search for new crop species and varieties,
and train students in the new methods of agriculture and conserva-
tion. Institutions of the future can be profitably built to include not
only these activities but also chemical prospecting and molecular
techniques of gene transfer from wild to domestic species.
3. Promote sustainable development. The rural poor of the Third World
are locked onto a downward spiral of poverty and the destruction of
322 The Human Impact
-------
diversity. To break free they need work that provides the basic food,
housing, and health care taken for granted by a great majority of
people in the industrialized countries. Without it, lacking access to
markets, hammered by exploding populations, they turn increasingly
to the last of the wild biological resources. They hunt out the animals
within walking distance, cut forests that cannot be regrown, put their
herds on any land from which they cannot be driven by force. They
use domestic crops ill suited to their environment, for too many
years, because they know no alternative. Their governments, lacking
an adequate tax base and saddled with huge foreign debts, collabo-
rate in the devastation of the environment. Using an accountant's
trick, they record the sale of forests and other irreplaceable natural
resources as national income without computing the permanent en-
vironmental losses as expense.
The poor are denied an adequate education. They cannot all move
into the cities; in most countries, and especially those in the tropics,
industrialization will be too slow to absorb more than a small fraction
into the labor force. Their striving billions will, for the next century
at least, have to be accommodated in rural areas. So the issue comes
down to this: how can people in developing countries achieve a
decent living from the land without destroying it?
The proving ground of sustainable development will be the tropical
rain forests. If the forests can be saved in a manner that improves
local economies, the biodiversity crisis will be dramatically eased.
Within that "if" are folded technical and social difficulties of the most
vexing kind. But many paths to the goal have been suggested, and
some have successfully tested.
One of the most encouraging advances to date is the demonstra-
tion, cited in the last chapter, that the extraction of nonrimber prod-
ucts from Peruvian rain forests can yield similar levels of income as
logging and farming, even with the limited outlets available in exist-
ing local markets. The practice has been regularized by the rubber
tappers of Brazil without a bit of theory or cost-benefit analysis. The
tappers, or seringueiros as they are locally called, are the descendants
of immigrants from northeastern Brazil who colonized portions of
the Amazon during the late nineteenth century and found a steady
living in latex harvesting. Half a million strong, they draw their
principal income today not only from rubber but also from Brazil
nuts, palm hearts, tonka beans, and other wild products. Each family
owns a house in the midst of harvesting pathways shaped like clover
leaves. In addition to harvesting natural products, rubber tappers
also hunt, fish, and practice small-scale agriculture in forest clearings.
Resolution 323
-------
Because they depend on biological diversity, the tappers are devoted
to the preservation of the forests as stable and productive ecosystems.
They are in fact full members of the ecosystems. In 1987 the Brazilian
government authorized the establishment of sermgueiro extractive
reserves on state land, with thirty-year renewable leases and a pro-
hibition on the clear-cutting of timber.
Extractive reserves represent a major conceptual advance, but they _
are not enough to save more than a small portion of the rain forests.
In 1980 rubber-tapper households occupied 2.7 percent of the area
of the North Region of Brazilian Amazonia, including the states of
Amazonas and Acre, while farms and ranches occupied 24 percent.
Only a small fraction of the flood of new immigrants now pouring
into the region can become extractivists. The rest will seek income
wherever they find it, primarily by advancing the agricultural fron-
tier. The key to the future of Amazonia and other forested tropical
regions is whether employment made available to them saves or
destroys the environment. "The real challenge," John Browder
writes, "is not where to designate extractive reserves, but rather,
how to integrate sustainable extraction and other natural forest man-
agement practices into the production strategies of those existing
rural properties, small farms and large ranches alike, that are re-
sponsible for most of the devastation being visited upon Amazonian
rainforests. Fundamentally, the problem is not where to sequester
forests, but how to turn people into better forest managers."
It is possible to harvest timber from the Amazonian wilderness
and other great remaining rain forests extensively and profitably with
little loss of biodiversity. The method of choice, first suggested by
Gary Hartshorn in 1979 and extended by other foresters, is strip
logging. While lowland forested basins are not rugged in terrain,
most are moderately rolling with well-defined slopes and dense sys-
tems of drainage streams. Strip logging imitates the natural fall of
trees that create linear gaps through the forest, with the artificial
gaps being aligned along the contours. The technique is described
by Carl Jordan:
In this scheme, a strip is harvested on the contour of a slope, parallel
to the stream. Along the upper edge of the stnp is a road used for
hauling out the logs. After harvesting, the area is left for a few years
until saplings begin to grow in the cut areas. Then the loggers clear-cut
another strip, this time above the road. The advantages of this system
are that the nutrients from the freshly cut second strip wash downslope
324 The Human Impact
-------
into the rapidly regenerating first strip, where the trees can quickly use
the nutrients, and that seeds from the mature forest above the cut area
will roll down into the recently cut strip. In contrast, in dear-cutting
there are no saplings with well-developed roots capable of retaining
nutrients in the system, nor is there a source of seed for regeneration
of the forest.
So far so good, but how can governments and local peoples be
persuaded to adopt such innovations as extractive reserves and strip
logging? The shift to sustainable development will depend as much
on education and social change as on science. Around the world
modest projects are being advanced with one common result: if
procedures tailored to the special case are used, economic develop-
ment and conservation can both be served. People can be persuaded;
they understand their own long-term interest and they can adapt.
Here are three successful programs from Latin America.
• By Panama law, the Kuna Indians hold sovereign rights over the
San Bias Islands and 300,000 hectares of adjacent mainland forest.
The Kuna maintain "spirit sanctuaries," areas of primary forest in
which only certain kinds of trees may be cut and no fanning is
allowed. Local communities depend on the sea for most of their
protein, on the forests for wood, game, and medicine, and on limited
patches of cleared land for domestic crops. When a spur of the Pan-
American Highway was brought to the edge of their land, the Kuna
established a forest reserve and guarded it with their own people.
Well aware of the outside world, welcoming to visitors, the tribes
have nevertheless chosen to discourage immigration and to preserve
their own culture within the bountiful natural environment that has
sustained them for centuries.
• Most of Central America, unlike the land of the Kuna, is plagued
by soil erosion and nutrient loss owing to the excessive cultivation
of maize and other crops, leading to the cutting of forests on ever
steeper slopes, all driven in turn by overpopulation. As production
declines, fanners invade the remaining natural areas in search of
more arable land. The process is especially acute in the Guinope
region of Honduras. In 1981 two private foundations, one interna-
tional and one Honduran, commenced a pilot program in some of
the Guinope villages under government auspices to raise productivity
and restore the land. They introduced drainage ditches, contour
furrows, grassy barriers, and intercropping with nitrogen-restoring
legumes. The field labor and implementation costs were provided
entirely by the farmers. Within several years, yields tripled and em-
Rtsolution 325
-------
igration nearly ceased. The new agricultural methods began to spread
to surrounding areas.
• When a highway, the Carretera Marginal de la Selva, was cut into
Peru's Palcazu Valley, 85 percent of the land was still clothed by rain
forest. Like most of the eastern tropical slopes of the Andes, the
valley is biologically rich, containing for example more than a thou-
sand species of trees. The region also supported about 3,000
Amuesha Indians and an equal number of settlers who had estab-
lished small landholdings over the previous fifty years. Once opened
to outside commerce, the typical fate of a western Amazonian valley
is to be clear-cut by new immigrants and logging companies, then
used for cattle ranches and small farms. The thin, acidic soil soon
loses most of its free phosphates and other nutrients, launching the
next phase: erosion, poverty, partial abandonment. For this valley,
however, an alternative plan was proposed by the U.S. Agency for
International Development and approved by the Peruvian govern-
ment. It is to extract timber by strip cutting, regulated to allow
perpetual regeneration of the forest through thirty- to forty-year
rotations. The plan permits limited permanent conversion of the most
arable land to agriculture and livestock production. But it also calls
for the establishment of a watershed reserve in the adjacent San
Marias mountain range and the designation of the neighboring Yana-
chaga range as the Yanachaga-Chemillen National Park. With luck,
the Palcazu will support a healthy human population and a slice of
Peru's biodiversity into the next century.
Wildlands and biological diversity are legally the properties of
nations, but they are ethically part of the global commons. The loss
of species anywhere d'>"iinishes wealth everywhere. Today the poor-
est countries are rapidly decapitahzing their natural resources and
unintentionally wiping out much of their biodiversity in a scramble
to meet foreign debts and raise the standard of living. By perceived
necessity they follow environmentally destructive policies that yield
the largest short-term profits. The rich debt-holding nations aggra-
vate the practice by encouraging a free market in poor countries
while providing subsidies to farmers at home.
Consider the infamous "hamburger connection" between the
United States and Central America. By 1983, in response to the
excellent U.S. market for beef, Costa Rican landowners had acceler-
ated the creation of new pastures until only 17 percent of the coun-
try's original forest cover was left. For a time it was the world's
leading exporter of beef to the United States. When northern tastes

Strip logging allow* a sustainable timber yield from forests, including the
relatively fragile rain forests. A corridor is cleared along the contours of the
land, narrow enough to allow natural regeneration within a few years. Another
corridor is then cut above the first, and so on, through a cycle lasting many
decades.
changed somewhat and the market fell, Costa Rica was left with a
denuded landscape and widespread soil erosion. It had also lost part
of its biological diversity.
Developing countries competing in an international free market
have a strong incentive to transfer capital into single-money crops
such as bananas, sugar cane, and cotton. To that end governments
often subsidize the clearing of wildlands and the overuse of pesticides
and fertilizers. The rush to maximize export income also concentrates
ever more acreage in the hands of a relatively few, politically favored
landowners. Small farmers are then forced to seek new land of mar-
ginal productivity, including natural habitats. Faced with ruin, they
have no choice but to press into nutrient-poor tropical forests, steep
hillside watersheds, coastal wetlands, and other final refuges of ter-
restrial diversity.
This journey to the precipice is hastened by the agricultural support
Resolution 327
-------
systems of the richest nations. At the present time subsidies to de-
veloped-world farmers total $300 billion a year, six times the official
foreign aid to Third World countries. When European Community
countries recently underwrote a large program of feedlot cattle rais-
ing, they created a huge artificial market for cassava. Landowners in
Thailand responded by clearing more tropical forest to grow cassava,
and in the process displaced large numbers of subsistence farmers
into the deep forest and up the eroding hillsides. When the United
States tightened import quotas of cane sugar to aid domestic growers,
U.S. imports from the Caribbean countries dropped 73 percent in ten
years, forcing many of the rural poor out of jobs in the plantations
and into marginal habitats for subsistence farming. Japan's extrava-
gant subsidy to its own rice farmers, intended to continue an ancient
agricultural tradition (the Japanese written character for rice means
"root of life"), has a depressing effect on the rice-growing populations
of tropical Asia. Once again, the impact on natural environments is
increased.
The richest countries set the rules for international trade. They
provide the bulk of loans and direct aid and control technology
transfer to the poor nations. It is their responsibility to use this power
wisely, in a manner that both strengthens these trading partners and
protects the global environment. They themselves will suffer if the
wildlands and biological diversity are not entered into the calculus
of trade agreements and international aid.
The raging monster upon the land is population growth. In its
presence, sustainability is but a fragile theoretical construct. To say,
as many do, that the difficulties of nations are not due to people but
to poor ideology or land-use management is sophistic. If Bangladesh
had 10 million inhabitants instead of 115 million, its impoverished
people could live on prosperous farms away from the dangerous
floodplains midst a natural and stable upland environment. It is also
sophistic to point to the Netherlands and Japan, as many commen-
tators incredibly still do, as models of densely populated but pros-
perous societies. Both are highly specialized industrial nations de-
pendent on massive imports of natural resources from the rest of the
world. If all nations held the same number of people per square
kilometer, they would converge in quality of life to Bangladesh rather
than to the Netherlands and Japan, and their irreplaceable natural
resources would soon join the seven wonders of the world as scat-
tered vestiges of an ancient history.
Every nation has an economic policy and a foreign policy. The time
328 The Human impact
-------
has come to speak more openly of a population policy. By this 1 mean
not just the capping of growth when the population hits the wall, as
in China and India, but a policy based on a rational solution of this
problem: what, in the judgment of its informed citizenry, is the
optimal population, taken for each country in turn, placed against the
backdrop of global demography? The answer will follow from an
assessment of the society's self-image, its natural resources, its ge-
ography, and the specialized long-term role it can most effectively
play in the international community. It can be implemented by en-
couragement or relaxation of birth control and the regulation of im-
migration, aimed at a target density and age distribution of the
national population. The goal of an optimal population will require
addressing, for the first time, the full range of processes that lock
together the economy and the environment, the national interest and
the global commons, the welfare of the present generation with that
of future generations. The matter should be aired not only in think
tanks but in public debate. If humanity then chooses to breed itself
and the rest of life into impoverishment, at least it will have done so
with open eyes.
4. Save what remains. Biodiversity can be saved by a mixture of
programs, but not all the programs proposed can work. Consider
one often raised in discussions by futurists. Suppose that we lost the
race to save the environment, that all natural ecosystems were al-
lowed to vanish. Could new species be created in the laboratory,
after generic engineers have learned how to assemble life from raw
organic compounds? It is doubtful. There is no assurance that organ-
isms can be generated artificially, at least not any as complex as
flowers or butterflies—or amoebae for that matter. Even this godlike
power would solve only half the problem, and the easy one at that.
The technicians would be working in ignorance of the history of the
extinct life they presumed to simulate. No knowledge exists of the
endless mutations and episodes of natural selection that inserted
billions of nucleotides into the now-vanished genomes, nor can it be
deduced in more than tiny fragments. The neospecies would be
creations of the human mind—plastic, neither historical nor adaptive,
and unfit for existence apart from man. Ecosystems built from them,
like zoos and botanical gardens, would require intensive care. But
this is not the time for science-fiction dreams.
On then to the next technical remedy that springs up in scientific
conferences and corridor arguments. Can extinct speaes be resur-
Resolutum 329
-------
rected from the DNA still preserved in museum specimens and fos-
sils? Again the answer is no. Fractions of genetic codes have been
sequenced from a 2400-year-old Egyptian mummy and magnolia
leaves preserved as rock fossils 18 million years ago, but they con-
stitute only the smallest portion of the genetic codes. Even that part
is hopelessly scrambled. To clone these organisms or a mammoth or
a dodo or any other extinct organism would be, as the molecular
biologist Russell Higuchi recently said, like taking a large encyclo-
pedia in an unknown language previously ripped into shreds and
trying to reassemble it without the use of your hands.
Consider the next possibility raised with regularity: why not just
forget the problem and let natural evolution replace the species that
are disappearing? It can be done if our descendants are willing to
wait several million years. Following the five great extinction epi-
sodes of geological history, full recovery of biodiversity required
between 10 and 100 million years. Even if Homo sapiens lasts that
long, the recovery would require returning a large part of the land
to its natural state. By appropriating or otherwise disturbing 90 per-
cent of the land surface, humanity has already closed most of the
theaters of natural evolution. And even if we did that much and
waited that long, the new biota would be very different from the one
we destroyed.
Then why not scoop up tissue samples of all living species and
freeze them in liquid nitrogen? They could be cloned later to produce
whole organisms. The method works for some microorganisms, in-
cluding viruses, bacteria, and yeasts, as well as the spores of fungi.
The American Type Culture Collection, located at Rockville, Mary-
land, contains over 50,000 species suspended in the deep sleep of
absolute biochemical inactivity, ready for warming and reactivation
as needed. The cultures are used in research, primarily in molecular
biology and medicine. It is possible that many larger organisms could
be similarly preserved in nitrogen sleep, at least as fertilized eggs, to
be reared later into mature individuals. Even scraps of undifferen-
tiated tissue might be stimulated into normal growth and develop-
ment. It has been done for organisms as complex as carrots and
frogs.
So let us suppose for argument that all kinds of plants and animals
are salvageable by such means, that biologists will perfect the tech-
niques of total inactivation and total recovery. The cryotorium in
which they would rest, the new Noah's ark, must house tens of
millions of species. The preservation of the content of even one
330 The Human Impact
-------
endangered habitat (say a mountain-ridge forest in Ecuador) would
be an immense operation enveloping thousands of species, most of
which are still unknown to science. Even if completed at the species
level, only a small fraction of the genetic variability of each species
could be practicably included. Unless the samples numbered into the
millions, great arrays of naturally occurring genetic strains would be
lost. And when the time comes to return the species to the wild, the
physical base of the ecosystem, including its soil, its unique nutrient
mix, and its patterns of precipitation, will have been altered so as to
make restoration doubtful. Cryopreservation is at best a last-ditch
operation that might rescue a few select species and strains certain
to die otherwise. It is far from the best way to save ecosystems and
could easily fail. The need to put an entire community of organisms
in liquid nitrogen would be tragic. Its enactment would be, in a
particularly piercing sense of the word, obscene.
I have spoken so far of the maintenance of species and genetic
stocks away from their natural habitats. Not all such methods are
fantastic or repugnant. One that works for many plants is the main-
tenance of seed banks: seeds are dried and kept in repositories over
long periods. The banks are kept in cool temperatures (about -20°C
is typical) but not in the suspended animation of liquid nitrogen.
Botanists have proved the technique effective for preserving most
strains of crop species. About a hundred countries maintain seed
banks and are adding to them steadily by exchanges and new col-
lecting expeditions. Their efforts are aided by the "Green Board," the
International Board for Plant Genetic Resources (IBPGR), an autono-
mous scientific organization located in Rome that composes part of
the network of the International Agricultural Research Centers. In
1990 over 2 million sets of seeds were on deposit, representing more
than 90 percent of the known local geographic varieties—landraces,
as they are called—of many of the basic food crops. Especially well
represented are wheat, maize, oats, potatoes, rice, and millet. An
effort has begun to include the wild relatives of existing crop species,
such as the richly promising perennial maize of Mexico. The method
can be extended to wild, noncrop floras of the world.
But there are serious problems with seed banks. Up to 20 percent
of plant species, some 50,000 in all, possess "recalcitrant" seeds that
cannot be stored by conventional means. Even if seed storage were
perfected for all kinds of plants, an unlikely prospect for the imme-
diate future, the task of collecting and maintaining many thousands
of endangered species and races would be stupendous All the efforts
Resolution 333
-------
of the existing seed banks to date have been barely enough to cover
a hundii'J species, and even those are in many cases poorly recorded
and of uncertain survival ability. Another difficulty: if reliance were
placed entirely on seed banks, and the species then disappeared in
the wild, the bank survivors would be stripped of their insect polli-
nators, root fungi, and other symbiotic partners, which cannot be
put in cold storage. Most of the symbionts would go extinct, pre-
venting the salvaged plant species from being replanted in the wild.
Other ex situ methods rely more realistically on captive populations
that grow and reproduce. There are about 1,300 botanical gardens
and arborerums in the world, many harboring plant species that are
endangered or extinct in the wild. As of June 1991, twenty such
institutions in the United States that subscribe to the registry of the
National Collection of Endangered Plants contained seeds, plants,
and cuttings of 372 species native to the United States. Some of the
gardens in North America and Europe are more global in their reach.
Harvard's Arnold Arboretum, for one, is famous for its collection of
Asiatic trees and shrubs. England's magnificent Kew Gardens is
engaged in a bold attempt to preserve and cultivate the last remnants
of the nearly vanished tree flora of St. Helena.
Animals are vastly more difficult than plants and microorganisms
to maintain ex situ. Zoos and other animal facilities have attempted
the task in heroic fashion. By the late 1980s, those around the world
whose stocks are known had gathered breeding populations of
540,000 individuals belonging to more than 3,000 species of mam-
mals, birds, reptiles, and amphibians. The collections include roughly
13 percent of the known land-dwelling species of vertebrate animals.
The better-financed zoos, including those in London, Frankfurt, Chi-
cago, New York, San Diego, and Washington, D.C., conduct basic
and veterinarian research with results that are applied to both captive
and wild populations. The rosters of 223 zoos in Europe and North
America are tracked by the International Species Inventory System
(ISIS), which uses the data to coordinate preservation and cross-
breeding. The ISIS zoos and research institutions aim not only to save
endangered animals but to reintroduce species into their native hab-
itats when land is made available. They have been successful with
three species, the Arabian oryx, the black-footed ferret, and the
golden lion tamarin. Attempts are underway or planned for at least
four other species, the California condor, the Bali starling, the Guam
rail, and the Przewalski horse, the ancestor of all domestic horses.
The ISIS facilities are trying to get ready if the giant panda, the
332 The Human Impact
-------
Sumatran rhinoceros, and the Siberian tiger, now on the brink,
should go extinct in the wild.
The best efforts by zoos, zooparks, aquariums, and research facil-
ities, however, slow the tide of extinction by a barely perceptible
amount. Even the groups of animals most favored by the public
cannot be completely served. Conservation biologists estimate that
as many as 2,000 species of mammals, birds, and reptiles can only
be salvaged if they are bred in captivity, a task beyond reach with
the means at hand. William Conway, director of the comprehensive
zoo maintained by the New York Zoological Society, believes that
existing facilities worldwide can sustain viable populations of no
more than 900 species. At best these survivors would contain only a
small fraction of their species' original genes. And far worse: no
provision at all has been made for the many thousands of species of
insects and other invertebrates that are equally at risk.
The dreams of scientists come to this: ex situ conservation is not
enough and will never be enough. Some of the methods are inval-
uable as safety nets for the fraction of endangered species that biology
best understands and the lay public is willing to support. But even
if countries everywhere chose to finance greatly enlarged cryobio-
logical vaults, seed banks, botanical gardens, and zoos, the facilities
could not be assembled quickly enough to save a majority of species
close to extinction from habitat destruction alone. Biologists are ham-
pered by lack of knowledge of more than 90 percent of the species
of fungi, insects, and smaller organisms on earth. They have no way
to ensure a reasonable sampling of genetic variation even in the
species rescued. They have only the faintest idea of how to reassem-
ble ecosystems from salvaged species, if indeed such a feat is possi-
ble. Not least, the entire process would be enormously expensive.
All these considerations converge to the same conclusion: ex situ
methods will save a few species otherwise beyond hope, but the
light and the way for the world's biodiversity is the preservation of
natural ecosystems. If that is accepted, we must face two realities
squarely. The first is that the habitats are disappearing at an accel-
erating rate and with them a quarter of the world's biodiversity. The
second is that the habitats cannot be saved unless the effort is of

immediate economic advantage to the poor people who live in and
around them. Eventually idealism and high purpose may prevail
around the world. Eventually an economically secure populace will
treasure their native biodiversity for its own sake. But at this moment
they are not secure and they, and we, have run out of time.
The rescue of biological diversity can only be achieved by a skillful
blend of science, capital investment, and government: science to
blaze the path by research and development; capital investment to
create sustainable markets; and government to promote the marriage
of economic growth and conservation.
The primary tactic in conservation must be to locate the world's
hot spots and to protect the entire environment they contain. Whole
ecosystems are the targets of choice because even the most charis-
matic species are but the representatives of thousands of lesser-
known species that live with them and are also threatened. The most
inclusive federal legislation in the United States is the Endangered
Species Act of 1973, which throws a protective shield around species
of "fish, wildlife, and plants" that are "endangered and threatened"
by human activities; as amended in 1978, the act also includes sub-
species. A bold and creative advance, the legislation is nevertheless
destined to be an arena of rising litigation. As any natural environ-
ment is reduced in area, the number of species that can live in it
indefinitely is also reduced. In other words, some species are doomed
to extinction even if all of the remaining habitat were to be preserved
from that time on. One of the principles of ecology, as I have stressed,
is that the number of species eventually declines by an amount
roughly equal to the sixth to third root of the area already lost.
Because the great majority of species of microorganisms, fungi, and
insects are not well known, it follows that they have been slipping
unnoticed through the cracks in the Endangered Species Act. Con-
flicts between developers and conservationists over birds, mammals,
and fishes are already commonplace. As ecosystems are better ex-
plored, less-conspicuous endangered species will come to light and
the number of clashes will grow.
There is a way out of the dilemma, other than abandoning legal
protection of America's fauna and flora altogether. As biodiversity
surveys are improved, the hot spots will come more sharply into
focus. Well-documented examples already include the embattled
coral reef of the Florida Keys and the rain forests of Hawaii and
Puerto Rico. As other local habitats are pinpointed, they can be
assigned the highest priority for conservation. This means, in most
336 The Human Impact
-------
cases, that they will be set aside as inviolate reserves. Warm spots,
areas less threatened or containing fewer species not found else-
where, can be zoned for partial development, with core preserves
centered on endemic species and races and buffer strips around the
preserves kept partly wild. Agricultural landscapes and harvested
forest tracts can be better designed to harbor rare species and races.
All these actions together, wisely administered, will be effective.
But the Endangered Species Act or an equivalent is also needed to
serve as a safety net for threatened forms of life in all environments,
whether harbored in reserves or not. Finally, in those rare cases
where the costs are perceived as intolerable by the electorate, a
compromise can be sought by means of population management.
This means transplantation of the species to suitable habitats nearby,
or restoring its environment in places where it was previously extin-
guished outside the zone of conflict, or—when all else fails—exile to
botanical gardens, zoos, or other ex situ preserves.
The area-species relation governing biodiversity shows that main-
tenance of existing parks and reserves will not be enough to save all
the species living within them. Only 4.3 percent of the earth's land
surface is currently under legal protection, divided among national
parks, scientific stations, and other classes of reserves. These frag-
ments represent recently shrunken habitat islands, whose faunas and
floras will continue to dwindle until a new, often lower equilibrium
is reached. Over 90 percent of the remaining land surface, including
most of the surviving high-diversity habitats, has been altered. If the
disturbance continues until most of the natural outside reserves are
swept away, a majority of the world's terrestrial species will be either
extinguished or put at extreme risk. And more: even the existing
reserves are in harm's way. Poachers and illegal miners invade them,
timber thieves work their margins, developers find ways to convert
them in part. During recent civil wars in Ethiopia, Sudan, Angola,
Uganda, and other African countries, many of the national parks
were left to ruin.
So we should try to expand reserves from 4.3 percent to 10 percent
of the land surface, to include as many of the undisturbed habitats
as possible with priority given to the world's hot spots. One of the
more promising means to attain this goal is by debt-for-nature swaps.
As currently practiced, conservation organizations such as Conser-
vation International, the Nature Conservancy, and the World Wildlife
Fund (U.S.) raise funds to purchase a portion of a country's com-
mercial debt at a discount, or else they persuade creditor banks to
Resolution 337
-------
donate some of it. This first step is easier than it sounds because so
many developing countries are close to default. The debts are then
exchanged in local currency or bonds set at favorable rates. The
enlarged equity is used to promote conservation, especially by the
purchase of land, environmental education, and the improvement of
land management. By early 1992 a total of twenty such agreements
totaling $110 million had been arranged in nine countries, including
Bolivia, Costa Rica, Dominican Republic, Ecuador, Mexico, Mada-
gascar, Zambia, the Philippines, and Poland.
In February 1991, to take one example, Conservation International
was authorized to buy $4 million in debt from Mexico's creditors
After discounting on secondary markets, the actual cost is expected
to be as little as $1.8 million. The conservation organization -has
agreed to forgive the full amount in return for the expenditure of
$2.6 million by the Mexican government on a broad range of conser-
vation projects. The most important initiative will be to preserve the
Lacandan tract in the extreme south of Mexico, the largest rain forest
in North America.
The debt of Third World countries has been reduced so far by only
one part in 10,000 through debt-for-nature swaps. Nor are the ar-
rangements without risk for the receiving country, notably in the
crowding out of domestic expenditures and a sparking of local infla-
tion. But these temporary effects are offset by the immense gain,
dollar for dollar, in the stabilization of the environment.
More potent still are unencumbered contributions from wealthier
nations channeled and carefully targeted through international assis-
tance organizations. The most important enterprise of this kind is
the Global Environment Facility (GEF), established in 1990 by the
World Bank, the United Nations Environmental Program, and the
United Nations Development Program At this writing, $450 million
has been committed to set up national parks, promote sustainable
forestry, and establish conservation trust funds in developing coun-
tries. Under consideration or already approved are proposals from
Bhutan, Indonesia, Papua New Guinea, the Philippines, Vietnam,
and the Central African Republic Two principal difficulties have
appeared within the GEF agenda. One is the limited absorptive power
of the recipient nations. With limited trained personnel and expert
knowledge, national leaders find it difficult to select the best projects
and initiate them effectively. Of much greater significance, the brief
terms of funding leave little prospect for the proper management
and protection of reserves when the money runs out. Fearing loss of
338 The Human Impact
-------
employment, the brightest professionals are likely to look to other
activities to ensure their futures. The solution to both problems may
he in the establishment of national trust funds, producing income
that can be fed into the conservation programs gradually and over a
period of many years. One such fund has recently been established
for Bhutan with the help of the World Wildlife Fund.
We come then to the design of the reserves themselves. As land
is set aside, the primary goal is to place the reserves in the regions
of highest diversity and to make them as large as possible. Another •
goal is to design their shape and spacing for retaining efficiency. In
approaching that secondary end, d debate has arisen in conservation
circles on the so-called SLOSS problem: whether to invest allotted
land into a Single Large reserve Or into Several Small reserves. A single
large reserve, to put the matter as simply as possible, possesses larger
populations of each species, but they all fit into one basket. A single
catastrophic fire or flood could extinguish a large part of the diversity
of the region. Breaking the reserve into several pieces reduces that
problem, but it also diminishes the size of the constituent populations
and hence threatens each with extinction. All might easily decline in
the face of widespread stress, such as drought or unseasonable cold.
Some biologists have suggested a compromise solution to the
SLOSS problem, which is to create small reserves connected by cor-
ridors of natural habitat. For example, several forest patches (say 10
kilometers square each) might be joined by strips of forest 100 meters
across. Then if a species vanishes from one of the patches, it can be
replaced by colonists immigrating along the forest corridor from an-
other patch. The disadvantage that critics of the compromise have
been quick to identify is that disease, predators, arid exotic compet-
itors can also use corridors to move through the network. Since
populations in the patches are small and vulnerable, all might fall
like a row of dominoes. I doubt that any general principle of popu-
lation dynamics exists that can resolve the SLOSS controversy, at least
not in the clean manner suggested by its simple geometric imagery.
Instead each ecosystem must be studied in turn to decide the best
design, which will depend on the species the system contains and
the year-by-year fluctuation of its physical environment. For the time
being, conservation biologists will agree on the cardinal rule: to save
the most biodiversity, make the reserves as large as possible.
5. Restore the wildlands. The grim signature of our time has been
the reduction of natural habitats until a substantial portion of the
Resolution 339
-------
kinds of plants and animals, certainly more than 10 percent, have
already vanished or else are consigned to early extinction. The toll
of genetic races has never been estimated, but it is almost certainly
much higher than that of species. Yet there is still time to save many
of the "living dead"—those so close to the brink that they will dis-
appear soon even if merely left alone. The rescue can be accom-
plished if natural habitats are not only preserved but enlarged, sliding
the numbers of survivable species back up the logarithmic curve that
connects quantity of biodiversity to amount of area. Here is the
means to end the great extinction spasm The" next century will, 1
believe, be the era of restoration in ecology.
In haphazard manner, largely through the abandonment of small
farms, the area of coniferous and hardwood forests in the eastern
United States has increased during the past hundred years. Delib-
erate efforts to enlarge wild areas are also underway. In 1935 a
pioneering effort resulted in the planting of 24 hectares of tall-grass
prairie at the University of Wisconsin Arboretum. The arboretum has
also served as the headquarters of the Center for Restoration Ecology,
devoted to research and the collation of information from projects in
other parts of the country. Elsewhere in the United States, small
restoration projects by the hundreds have been initiated, all devoted
to the increase in area of natural habitats and the return of degraded
ecosystems to full health. They range broadly in ecosystem types,
from the ironwood groves of Santa Catalina Island to the Tobosa
grassland of Arizona, the Oakland understory of California's Santa
Monica Mountains, the magnificent open mountain woodlands of
Colorado, and last savanna remnants of Illinois. They include frag-
ments of salt and freshwater wetlands from California to Florida and
Massachusetts.
In Costa Rica an audacious effort by the American ecologist Daniel
Janzen and local conservation leaders has led to the establishment of
Guanacaste National Park, a 50,000-hectare reserve in the north-
western corner of the country. The park will be created—literally
created—by the regrowth of dry tropical forest planted on cattle
ranches. The Guanacaste dream was bom of recognition that in
Central America dry forest is even more threatened than rain forest,
down to only 2 percent of its original cover The plan is to use existing
patches of the original forest to seed a steadily growing area of
ranchland. The conversion will be made easier by the low density of
the human population in the area The regenerating woodland will
provide a protected watershed, an income from tourism expected to
340 The Human Impact
-------
reach $1 million or more annually, and a net increase in employment
of the area's residents. Most important in the long run, it will save
a significant part of Costa Rica's natural heritage.
I have spoken of the salvage and regeneration of existing ecosys-
tems. There will come a time when even more is possible with the
aid of scientific knowledge. The return to biology's Eden might also
include the creation of synthetic faunas and floras, assemblages of
species carefully selected from different parts of the world and intro-
duced into impoverished habitats. The idea struck home for me one
late afternoon as I sat at the edge of the artificial lake near the center
of the University of Miami campus, surrounded by the densely ur-
banized community of Coral Gables. At least six species of fishes
swarmed in the clear brackish water within 2 meters of shore, some
as solitary foragers, others in schools. Most were exotics Their un-
usual diversity and beauty reminded me of a newly created coral
reef. As the sun set and the water darkened, a large predator fish,
probably a gar, broke the surface in the middle of the lake. A small
alligator glided out from reeds across the way and cruised into open
water. Well beyond the far shore, a flock of parrots returned noisily
to their palm-top evening roost. They belonged to one of more than
twenty exotic species that breed or occur in the Miami area, all
originating from individuals that escaped or were deliberately re-
leased from captivity. Thus has the parrot family, the Psittacidae,
returned to Florida with a vengeance, only decades after the exter-
mination of the Carolina parakeet, last of the endemic North Amer-
ican species. With flashing wings they salute the vanished native.
It is dangerous, I must quickly add, to think too freely of intro-
' ducing exotics anywhere. They might or might not take to the new
environment—between 10 and 50 percent of bird species have suc-
ceeded, depending on the part of the world and the number of
attempts made to introduce them. Exotics might become economic
pests or force out native species. A few, like rabbits, goats, pigs, and
the notorious Nile perch are capable not only of extinguishing indi-
vidual species but of degrading entire habitats Ecology is still too
primitive a science to predict the outcome of the synthesis of prede-
signed biotas. No responsible person will risk dumping destroyers
into the midst of already diminished communities. Nor should we
delude ourselves into thinking that synthetic biotas increase global
diversity. They only increase local diversity by expanding the ranges
and population sizes of selected species.
Yet the search for the safe rules of biohc synthesis is an enterprise
Resolution 341
-------
of high intellectual danng. If the effort is successful, regions already
stripped of their native biotas can be restored to places of diversity
and environmental stability. A wilderness of sorts can be reborn in
the wasteland. Species already extinct in the wild, those now main-
tained in zoos and gardens, deserve high priority. Transplanted into
impoverished or synthetic biotas, they can endure as orphan species
in foster ecosystems. Even though their original home has been
closed to them, they will regain security and independence. They
will repay us by attaining one criterion of wilderness—that we are
allowed to lay down the burden of their care and visit them as equal
partners, on our own time. A few species will be prosthetic. As
keystone elements, such as a tree able to grow rapidly and shelter
many other plant and animal species, they will play a disproportion-
ate role in holding the new communities together.
Finally, the question of central interest is how much of the world's
biodiversity we can expect to carry with us out of the bottleneck fifty
or a hundred years hence. Let me venture a guess. If the biodiversity
crisis remains largely ignored and natural habitats continue to de-
cline, we will lose at least one quarter of the earth's species. If we
respond with the knowledge and technology already possessed, we
may hold the loss to 10 percent. At first glance the difference may
seem bearable. It is not; it amounts to millions of species.
I feel no hesitance in urging the strong hand of protective law and
international protocols in the preservation of biological wealth, as
opposed to tax incentives and marketable pollution permits. In dem-
ocratic societies people may think that their government is bound by
an ecological version of the Hippocratic oath, to take no action that
knowingly endangers biodiversity. But that is not enough. The com-
mitment must be much deeper—to let no species knowingly die, to
take all reasonable action to protect every species and race in per-
petuity. The government's moral responsibility in the conservation
of biodiversity is similar to that in public health and military defense.
The preservation of species across generations is beyond the capacity
of individuals or even powerful private institutions. Insofar as bio-
diversity is deemed an irreplaceable public resource, its protection
should be bound into the legal canon

CHAPTER FIFTEEN
The Environmental Ethic
THE SIXTH GREAT extinction spasm of geological time is
upon us, grace of mankind. Earth has at last acquired a
force that can break the crucible of biodiversity. 1 sensed it with
special poignancy that stormy night at Fazenda Dimona, when
lightning flashes revealed the rain forest cut open like a cat's
eye for laboratory investigation. An undisturbed forest rarely
discloses its internal anatomy with such clarity. Its edge is
shielded by thick secondary growth or else, along the river
bank, the canopy spills down to ground level The nighttime
vision was a dying artifact, a last glimpse of savage beauty.
A few days later I got ready to leave Fazenda Dimona: gath-
ered my muddied clothes in a bundle, gave my imitation Swiss
army knife to the cook as a farewell gift, watched an overflight
of Amazonian green parrots one more time, labeled and stored
my specimen vials in reinforced boxes, and packed my field
notebook next to a dog-eared copy of Ed McBam's police novel
Ice, which, because I had neglected to bring any other reading
matter, was now burned into my memory
Grinding gears announced the approach of the truck sent to
take me and two of the forest workers back to Manaus. In bright
sunlight we watched it cross the pastureland, a terrain strewn
with fire-blackened stumps and logs, the battlefield my forest
had finally lost. On the ride back I tried not to look at the bare
fields. Then, abandoning my tourist Portuguese, I turned in-
ward and daydreamed. Four splendid lines of Virgil came to
mind, the only ones I ever memorized, where the Sibyl warns
343
-------
Aeneas of the Underworld:
The way downward is easy from Avemus.
Black Dis's door stands open night and day.
But to retrace your steps to heaven's air,
There is the trouble, there is the toil . .
For the green prehuman earth is the mystery we were chosen to
solve, a guide to the birthplace of our spirit, but it is slipping away.
The way back seems harder every year. If there is danger in the
human trajectory, it is not so much in the survival of our own species
as in the fulfillment of the ultimate irony of organic evolution: that
in the instant of achieving self-understanding through the mind of
man, life has doomed its most beautiful creations. And thus human-
ity closes the door to its past.
The creation of that diversity came slow and hard: 3 billion years
of evolution to start the profusion of animals that occupy the seas,
another 350 million years to assemble the rain forests in which half
or more of the species on earth now live. There was a succession of
dynasties. Some species split into two or several daughter species,
and their daughters split yet again to create swarms of descendants
that deployed as plant feeders, carnivores, free swimmers, gliders,
sprinters, and burrowers, in countless motley combinations. These
ensembles then gave way by partial or total extinction to newer
dynasties, and so on to form a gentle upward swell that carried
biodiversity to a peak—just before the arrival of humans. Life had
stalled on plateaus along the way, and on five occasions it suffered
extinction spasms that took 10 million years to repair. But the thrust
was upward. Today the diversity of life is greater than it was a 100
million years ago—and far greater than 500 million years before that.
Most dynasties contained a few species that expanded dispropor-
tionately to create satrapies of lesser rank. Each species and its de-
scendants, a sliver of the whole, lived an average of hundreds of
thousands to millions of years. Longevity varied according to taxo-
nomic group. Echinoderm lineages, for example, persisted longer
than those of flowering plants, and both endured longer than those
of mammals.
Ninety-nine percent of all the species that ever lived are now
extinct. The modern fauna and flora are composed of survivors that
somehow managed to dodge and weave through all the radiations
and extinctions of geological history. Many contemporary world-
344 The Human Impact
-------
dominant groups, such as rats, ranid frogs, nymphalid butterflies,
and plants of the aster family Compositae, attained their status not
long before the Age of Man. Young or old, all living species are direct
descendants of the organisms that lived 3.8 billion years ago. They
are living genetic libraries, composed of nucleotide sequences, the
equivalent of words and sentences, which record evolutionary events
all across that immense span of time. Organisms more complex than
bacteria—protists, fungi, plants, animals—contain between 1 and 10
billion nucleotide letters, more than enough in pure information to
compose an equivalent of the Encyclopaedia Britannia. Each species
is the product of mutations and recombinations too complex to be
grasped by unaided intuition. It was sculpted and burnished by an
astronomical number of events in natural selection, which killed off
or otherwise blocked from reproduction the vast majority of its mem-
ber organisms before they completed their lifespans. Viewed from
the perspective of evolutionary time, all other species are our distant
kin because we share a remote ancestry. We still use a common
vocabulary, the nucleic-acid code, even though it has been sorted
into radically different hereditary languages.
Such is the ultimate and cryptic truth of every kind of organism,
large and small, every bug and weed. The flower in the crannied
wall—it is a miracle. If not in the way Tennyson, the Victorian ro-
mantic, bespoke the portent of full knowledge (by which "I should
know what,God and man is"), then certainly a consequence of all
we understand from modern biology. Every kind of organism has
reached this moment in time by threading one needle after another,
throwing up brilliant artifices to survive and reproduce against nearly
impossible odds.
Organisms are all the more remarkable in combination. Pull out
the flower from its crannied retreat, shake the soil from the roots
into the cupped hand, magnify it for close examination. The black
earth is alive with a riot of algae, fungi, nematodes, mites, springtails,
enchytraeid worms, thousands of species of bacteria. The handful
may be only a tiny fragment of one ecosystem, but because of the
genetic codes of its residents it holds more order than can be found
on the surfaces of all the planets combined. It is a sample of the
living force that runs the earth—and will continue to do so with or
without us.
We may think that the world has been completely explored. Almost
all the mountains and rivers, it is true, have been named, the coast
and geodetic surveys completed, the ocean floor mapped to the
The Environmental Ethic 345
-------
deepest trenches, the atmosphere transected and chemically ana-
lyzed. The planet is now continuously monitored from space by
satellites; and, not least, Antarctica, the last virgin continent, has
become a research station and expensive tourist stop. The biosphere,
however, remains obscure. Even though some 1.4 million species of
organisms have been discovered (in the minimal sense of having
specimens collected and formal scientific names attached), the total
number alive on earth is somewhere between 10 and 100 million. No
one can say with confidence which of these figures is the closer. Of
the species given scientific names, fewer than 10 percent have been
studied at a level deeper than gross anatomy The revolution in
molecular biology and medicine was achieved with a still smaller
fraction, including colon bacteria, corn, fruit flies, Norway rats, rhe-
sus monkeys, and human beings, altogether comprising no more
than a hundred species.
Enchanted by the continuous emergence of new technologies and
supported by generous funding for medical research, biologists have
probed deeply along a narrow sector of the front. Now it is time to
expand laterally, to get on with the great Linnean enterprise and
finish mapping the biosphere. The most compelling reason for the
broadening of goals is that, unlike the rest of science, the study of
biodiversity has a time limit. Species are disappearing at an acceler-
ating rate through human action, primarily habitat destruction but
also pollution and the introduction of exotic species into residual
natural environments. I have said that a fifth or more of the species
of plants and animals could vanish or be doomed to early extinction
by the year 2020 unless better efforts are made to save them. This
estimate comes from the known quantitative relation between the
area of habitats and the diversity that habitats can sustain. These
area-biodiversity curves are supported by the general but not uni-
versal principle that when certain groups of organisms are studied
closely, such as snails and fishes and flowering plants, extinction is
determined to be widespread. And the corollary: among plant and
animal remains in archaeological deposits, we usually find extinct
species and races. As the last forests are felled in forest strongholds
like the Philippines and Ecuador, the decline of species will accelerate
even more. In the world as a whole, extinction rates are already
hundreds or thousands of times higher than before the coming of
man. They cannot be balanced by new evolution in any period of
time that has meaning for the human race.
Why should we care? What difference does it make if some species
346 The Human Impact
-------
are extinguished, if even half of all the species on earth disappear?
Let me count the ways. New sources of scientific information will be
lost. Vast potential biological wealth will be destroyed. Still unde-
veloped medicines, crops, pharmaceuticals, timber, fibers, pulp, soil-
restonng vegetation, petroleum substitutes, and other products and
amenities will never come to light. It is fashionable in some quarters
to wave aside the small and obscure, the bugs and weeds, forgetting
that an obscure moth from Latin America saved Australia's pasture-
land from overgrowth by cactus, that the rosy periwinkle provided
the cure for Hodgkin's disease and childhood lymphocytic leukemia,
that the bark of the Pacific yew offers hope for victims of ovarian
and breast cancer, that a chemical from the saliva of leeches dissolves
blood clots during surgery, and so on down a roster already grown
long and illustrious despite the limited research addressed to it.
In amnesiac revery it is also easy to overlook the services that
ecosystems provide humanity. They enrich the soil and create the
very air we breathe. Without these amenities, the remaining tenure
of the human race would be nasty and brief. The life-sustaining
matrix is built of green plants with legions of microorganisms and
mostly small, obscure animals—in other words, weeds and bugs.
Such organisms support the world with efficiency because they are
so diverse, allowing them to divide labor and swarm over every
square meter of the earth's surface. They run the world precisely as
we would wish it to be run, because humanity evolved within living
communities and our bodily functions are finely adjusted to the
idiosyncratic environment already created. Mother Earth, lately
called Gaia, is no more than the commonality of organisms and the
physical environment they maintain with each passing moment, an
environment that will destabilize and turn lethal if the organisms are
disturbed too much. A near infinity of other mother planets can be
envisioned, each with its own fauna and flora, all producing physical
environments uncongenial to human life. To disregard the diversity
of life is to risk catapulting ourselves into an alien environment. We
will have become like the pilot whales that inexplicably beach them-
selves on New England shores.
Humanity coevolved with the rest of life on this particular planet;
other worlds are not in our genes. Because scientists have yet to put
names on most kinds of organisms, and because they entertain only
a vague idea of how ecosystems work, it is reckless to suppose that
biodiversity can be diminished indefinitely without threatening hu-
manity itself. Field studies show that as biodiversity is reduced, so
The Environmental Ethic 347
-------
is the quality of the services provided by ecosystems. Records of
stressed ecosystems also demonstrate that the descent can be unpre-
dictably abrupt. As extinction spreads, some of the lost forms prove
to be keystone species, whose disappearance brings down other
species and triggers a ripple effect through the demographies of the
survivors. The loss of a keystone species is like a drill accidentally
striking a powerline. It causes lights to go out all over.
These services are important to human welfare. But they cannot
form the whole foundation of an enduring environmental ethic. If a
price can be put on something, that something can be devalued,
sold, and discarded. It is also possible for some to dream that people
will go on living comfortably in a biologically impoverished world.
They suppose that a prosthetic environment is within the power of
technology, that human life can still flourish in a completely human-
ized world, where medicines would all be synthesized from chemi-
cals off the shelf, food grown from a few dozen domestic crop spe-
cies, the atmosphere and climate regulated by computer-driven
fusion energy, and the earth made over until it becomes a literal
spaceship rather than a metaphorical one, with people reading dis-
plays and touching buttons on the bridge. Such is the terminus of
the philosophy of exemptionalism: do not weep for the past, hu-
manity is a new order of life, let species die if they block progress,
scientific and technological genius will find another way. Look up
and see the stars awaiting us.
But consider: human advance is determined not by reason alone
but by emotions peculiar to our species, aided and tempered by
reason. What makes us people and not computers is emotion. We
have little grasp of our true nature, of what it is to be human and
therefore where our descendants might someday wish we had di-
rected Spaceship Earth. Our troubles, as Vercors said in You Shall
Know Them, arise from the fact that we do not know what we are
and cannot agree on what we want to be. The primary cause of this
intellectual failure is ignorance of our origins. We did not arrive on
this planet as aliens. Humanity is part of nature, a species that
evolved among other species The more closely we identify ourselves
with the rest of life, the more quickly we will be able to discover the
sources of human sensibility and acquire the knowledge on which
an enduring ethic, a sense of preferred direction, can be built.
The human heritage does not go back only for the conventionally
recognized 8,000 years or so of recorded history, but for at least 2
million years, to the appearance of the first "true" human beings.
348 The Human Impact
-------
the earliest species composing the genus Homo. Across thousands of
generations, the emergence of culture must have been profoundly
influenced by simultaneous events in generic evolution, especially
those occurring in the anatomy and physiology of the brain. Con-
versely, genetic evolution must have been guided forcefully by the
kinds of selection rising within culture.
Only in the last moment of human history has the delusion arisen
that people can flourish apart from the rest of the living world.
Preliterate societies were in intimate contact with a bewildering array
of life forms. Their minds could only partly adapt to that challenge.
But they struggled to understand the most relevant parts, aware that
the right responses gave life and fulfillment, the wrong ones sickness,
hunger, and death. The imprint of that effort cannot have been erased
in a few generations of urban existence. I suggest that it is to be
found among the particularities of human nature, among which are
these:
• People acquire phobias, abrupt and intractable aversions, to the
objects and circumstances that threaten humanity in natural environ-
ments: heights, closed spaces, open spaces, running water, wolves,
spiders, snakes. They rarely form phobias to the recently invented
contrivances that are far more dangerous, such as guns, knives,
automobiles, and electric sockets.
• People are both repelled and fascinated by snakes, even when
they have never seen one in nature. In most cultures the serpent is
the dominant wild animal of mythical and religious symbolism. Man-
hattanites dream of them with the same frequency as Zulus. This
response appears to be Darwinian in origin. Poisonous snakes have
been an important cause of mortality almost everywhere, from Fin-
land to Tasmania, Canada to Patagonia; an untutored alertness in
their presence saves lives. We note a kindred response in many
primates, including Old World monkeys and chimpanzees: the ani-
mals pull back, alert others, watch closely, and follow each potentially
dangerous snake until it moves away. For human beings, in a larger
metaphorical sense, the mythic, transformed serpent has come to
possess both constructive and destructive powers: Ashtoreth of the
Canaanites, the demons Fu-Hsi and Nu-kua of the Han Chinese,
Mudamma and Manasa of Hindu India, the triple-headed giant Ne-
hebkau of the ancient Egyptians, the serpent of Genesis conferring
knowledge and death, and, among the Aztecs, Cihuacoatl, goddess
of childbirth and mother of the human race, the rain god Tlaloc, and
Quetzalcoatl, the plumed serpent with a human head who reigned
The Environmental Ethic 349
-------
as lord of the morning and evening star. Ophidian power spills over
into modern life: two serpents entwine the caduceus, first the winged
staff of Mercury as messenger of the gods, then the safe-conduct
pass of ambassadors and heralds, and today the universal emblem
of the medical profession.
• The favored living place of most peoples is a prominence near
water from which parkland can be viewed. On such heights are
found the abodes of the powerful and rich, tombs of the great,
temples, parliaments, and monuments commemorating tribal glory.
The location is today an aesthetic choice and, by the implied freedom
to settle there, a symbol of status. In ancient, more practical rimes
the topography provided a place to retreat and a sweeping prospect
from which to spot the distant approach of storms and enemy forces.
Every animal species selects a habitat in which its members gain a
favorable mix of security and food. For most of deep history, human
beings lived in tropical and subtropical savanna in East Africa, open
country sprinkled with streams and lakes, trees and copses. In similar
topography modern peoples choose their residences and design their
parks and gardens, if given a free choice. They simulate neither dense
jungles, toward which gibbons are drawn, nor dry grasslands, pre-
ferred by hamadryas baboons In their gardens they plant trees that
resemble the acacias, sterculias, and other native trees of the African
savannas. The ideal tree crown sought is consistently wider than tall,
with spreading lowermost branches close enough to the ground to
touch and climb, clothed with compound or needle-shaped leaves.
• Given the means and sufficient leisure, a large portion of the
populace backpacks, hunts, fishes, birdwatches, and gardens. In the
United States and Canada more people visit zoos and aquariums
than attend all professional athletic events combined. They crowd
the national parks to view natural landscapes, looking from the tops
of prominences out across rugged terrain for a glimpse of tumbling
water and animals living free. They travel long distances to stroll
along the seashore, for reasons they can't put into words.
These are examples of what I have called biophilia, the connections
that human beings subconsciously seek with the rest of life. To
biophilia can be added the idea of wilderness, all the land and com-
munities of plants and animals still unsullied by human occupation.
Into wilderness people travel in search of new life and wonder, and
from wilderness they return to the parts of the earth that have been
humanized and made physically secure. Wilderness settles peace on
the soul because it needs no help; it is beyond human contrivance.
350 The Human Impact
-------
Wilderness is a metaphor of unlimited opportunity, rising from the
tribal memory of a rime when humanity spread across the world,
valley to valley, island to island, godstruck, firm in the belief that
virgin land went on forever past the horizon.
I cite these common preferences of mind not as proof of an innate
human nature but rather to suggest that we think more carefully and
rum philosophy to the central questions of human origins in the wild
environment. We do not understand ourselves yet and descend far-
ther from heaven's air if we forget how much the natural world
means to us. Signals abound that the loss of life's diversity endangers
not just the body but the spirit. If that much is true, the changes
occurring now will visit harm on all generations to come.
The ethical imperative should therefore be, first of all, prudence.
We should judge every scrap of biodiversity as priceless while we
learn to use it and come to understand what it means to humanity.
We should not knowingly allow any species or race to go extinct.
And let us go beyond mere salvage to begin the restoration of natural
environments, in order to enlarge wild populations and stanch the
hemorrhaging of biological wealth. There can be no purpose more
enspiriting than to begin the age of restoration, reweaving the won-
drous diversity of life that still surrounds us.
The evidence of swift environmental change calls for an ethic un-
coupled from other systems of belief. Those committed by religion
to believe that life was put on earth in one divine stroke will recognize
that we are destroying the Creation, and those who perceive biodi-
versity to be the product of blind evolution will agree. Across the
other great philosophical divide, it does not matter whether species
have independent rights or, conversely, that moral reasoning is
uniquely a human concern. Defenders of both premises seem des-
tined to gravitate toward the same position on conservation.
The stewardship of environment is a domain on the near side of
metaphysics where all reflective persons can surely find common
ground. For what, in the final analysis, is morality but the command
of conscience seasoned by a rational examination of consequences?
And what is a fundamental precept but one that serves all genera-
tions? An enduring environmental ethic will aim to preserve not only
the health and freedom of our species, but access to the world in
which the human spirit was born.

II.
Focus on the key concept of forest fragmentation.
Illustrate this by drawing two areas, classified as 50%
forest, but with different patterns of use, as follows:
Q = home
m = forest
"Checkerboard" pattern
Discuss the advantages and disadvantages of each
pattern, for survival of birds, biodiversity and forest
ecosystems. Discuss common patterns of human land use,
such as that depicted in "Birds Over Troubled Forests",
p. 28, and 'Silence of the Songbirds", pp. 70, 82-90.
Discuss which pattern has more forest edge, which poses
threats to survival of forest birds, and which area
contains more deep forest. Explain key research into
biodiversity, such as Edward 0. Wilson, who reports in
The Diversity of Life, that "[a]s a rule of thumb, a
tenfold increase in area results in a doubling of the
number of species" (p. 205).

woodlands. "Nice cuddly
chipmunks can be aggres
sive raiders," notes
ornithologist Richard
Holmes, who has placed
decoy nests in New
Hampshire forests to
study predators such as
the mink-like fisher
(above). His work shows
that nesting losses for
one migratory songbird,
the American redstart,
can reach 70 percent.
Resident birds lifee
woodpecfeers or chicka-
dees fare better against
nest piracy — they fight
off attackers more often,
and they lodge in safer
tree holes.

The trail beyond is submerged
and we retreat to a corridor cut
warblers whose courtship songs are
rarely heard in winter. Jamaicans call
them, collectively, "chip-chips " Or
simply "Christmas birds," to distin-
guish the winter visitors from their
familiar resident species
Tom Sherry, whom I last saw at
Hubbard Brook in New Hampshire,
sloshes from the swamp with a male
redstart in hand Using a stuffed red-
start and taped songs of the species, it
had taken him only minutes to lure
the bird— outraged at the idea of a
competitor for its turf— into a "mist"
net virtually invisible to birds. As in
previous years, Sherry and colleague
Richard Holmes aim to capture and
band every redstart and mark its ter-
ritory on this 13-acre study plot at the
edge of one of the few large stands of
mangroves left on the island
"Many Neotropical migrants are
aggressive in defending their winter
living space," Sherry explains, "and
individuals will occupy the same ter-

Bfdman's warbler. A species is endangered if it occur* over awide
area but is scarce throughout its range. Such is the case of Badunan'i
warbier (Vermroon bachmanii), whkh is the rarest bird in Nor* Affle**
fca in numbers of individuals per square kilometer of its geographic*
range. Small, yellow-breasted, olive-green^ on the back, and btadr
throated in the male, the warbler once bred in thicfcet-grow* tw«!
swamps from Arkansas to South Carolina. Its present breeding rangffi
and population size are unknown, and it appears to be dose. M|
extinction if not already lost.
Kirtlmd's warbler. A species is rare if it is densely concentrated bat
limited to a few small populations restricted to tiny range*. Kirtland s.
warbler (Dendroica kirtlandii), with lemon-yellow breast, bluish-gray
back streaked with black, and dark mask in the male, is such a case.
It is loosely colonial, with a breeding range restricted to jack-pine
country in the north-central part of the lower peninsula of Michigan.
Between 1961 and 1971 the known population plunged from 1,000
to 400 birds. The decline was apparently due to increased nest par-
asitism by brown-headed cowbirds (Molothrus ater), which place their
eggs in the warbler's nest. Kirtland's warblers are as dense as ever
in the localities where they occur, but the progressive restriction of
their range has brought them close to extinction.
Red-cockaded woodpecker. A species can be rare even if it has a broad
range and is locally numerous, but is specialized to occupy a scarce
niche. The red-cockaded woodpecker (Picoides borealis), with zebra
back, white breast speckled with black, and each white cheek touched
by a carmine speck, is the outstanding example. It ranges across most
of the southeastern United States but requires pine forests at least
eighty years old. The birds live in small societies composed of a
breeding pair and up to several offspring, with the latter helping
their parents to protect and rear the younger siblings. Each group
requires an average of 86 hectares of woodland to produce an ade-
quate harvest of insect prey. To nest, red-cockaded woodpeckers
hollow out cavities in living, mature longleaf pines eighty to one
hundred and twenty years old, in which the heartwood has already
been destroyed by fungus. These exacting conditions are no longer
easy to find in the piney woods of the south. The total size of the
woodpecker breeding population was estimated in 1986 to be only
6,000. It was falling steadily, by as much as 10 percent a year in Texas
and probably just as fast elsewhere. The species appears doomed
unless the cutting of the oldest pine forests is stopped immediately.
Species trapped by specialization and pressed by shrinking habitat
form the largest endangered class. The scarcity of Bachman's warbler
across the southern United States is no mystery, despite the abun-
dance of riverine swampland in which it can breed. It winters (or
wintered) exclusively in the forests of western Cuba and the nearby
Isle of Pines, where virtually all the forests have been cleared to grow
sugar cane. The bottleneck is the loss of wintering ground and star.
vation for even the remnant of warblers produced in the lusher
summer environment of the United States.
John Terborgh has given a poignant account of his own experience
with one of the last Bachman's warblers. In May 1954, asan eighteen-
year-old birder (now a foremost onuttologBt),

sighting of a male Bachman's on Pohick Creek in Virginia not far
from his home. The song of the Bachman's had been described to
him as resembling that of a black-throated green warbler with a
downward sweep at the end: zee-zee-zee-zee-tsew.
To my astonishment I walked up to the place that had been described
to me and heard it! I had no trouble seeing the bird. A full-plumaged
male, it sat on an open branch about 20 feet up and gave me a perfect
view while it sang. It hardly stopped singing during the two hours I
spent there. Reluctantly, I pulled myself away, wondering whether this
was an experience 1 would ever repeat. It was not.
As other birders were to testify, the male returned to the same spot
the next two springs. No female ever joined him. The extraordinary
exertions of the Bachman's male were a sign that he was in prime
breeding condition, but he was destined to go undiscovered by any
female of the same speaes.
I imagine that each spnng a tiny remnant of birds crossed the Gulf of
Mexico and fanned out into a huge area in the Southeast, where they
became, so to speak, needles in a haystack. Toward the end, it is likely
that most of the males in the population, like the one at Pohick Creek,
were never discovered by females. Once this situation developed, there
could have been no possible salvation for the species in the wild.
In parallel manner, Kirtland's warbler winters in the pine wood-
land of two islands in the northern Bahamas, Grand Bahama and
Abaco. Terborgh has written that, however zealously the Kirtland's
warbler and its habitat may be protected in Michigan, its fate prob-
ably lies at the mercy of commercial interests in the Bahamas. Mi-
gratory birds as a whole are declining across the United States from
the same environmental malady that afflicts the warblers: wintering
grounds are being demolished by logging and burning. The prospects
are. especially gnm for species that depend on the rapidly shrinking
forests of Mexico, Central America and the West Indies.
The rarest songbird: Bachouu?* warbler of the southeastern United
States is on the brink of extinction, if not already gone. This drawing of
a singing male is based on on* of the last photographs taken.

Interview with John G. Robinson
WITH EACH NEW HUMAN IMPACT on wilderness,
survival prospects for Earth's other species de-
cline. In recent years scientists, conservation-
ists, ethicists and others have wrestled with a
lew set of ideas—a kind of big-picture strate-
gy—for deciding how to respond. One of the most
promising is called sustainable use: using today's re-
sources in ways that assure they will be around to
benefit future generations. How to protect plants and
wildlife while exploiting them for human needs is a
particularly thorny aspect of this idea, especially since
the "rules" of biology are different for each kind of
ecosystem.
For a fresh perspective on what's involved, Inter-
national Wildlife turned to conservation strategist
John G. Robinson, who oversees 160 conservation
projects in 44 countries for a newly named entity call-
ed NYZS The Wildlife Conservation Society (formerly
the New York Zoological Society and its conservation
division, Wildlife Conservation International). Here
are some of his views; as presented in a conversation
with International Wildlife Editor Jonathan Fisher:
International Wildlife: Our planet is losing species
faster than at any time since the extinction of the di-
nosaurs. As you look ahead—say, to the year 2020—
For conservation strategist Robinson, our world is
a mosaic of four vastly different land uses (left and
right). Not all four preserve natural systems, but
together they may form a sustainable whole, saving
wild species while meeting human needs. How much
land we set aside for wildlife depends on our resolve.

MEETING PEOPLES' NEEDS
"We're trying to raise the quality of life of all people. Simple
mathematics will tell you that there is not enough biological potential
to support that kind of aspiration."
what kind of world do you
think we will be living in?
John Robinson: The world
I would like to see out there is
what might be called a sustain-
able landscape. It has wilder-
ness. It has areas where people
extract natural resources. It
has areas with intensive agri-
culture. And it has urban and
industrial areas. Overall, it is a
mosaic of different land uses,
but taken as a whole, it would
protect natural systems and it
would allow people to live sus-
tainably.
IW: Can our world really be
sustainable? Will it be here to-
morrow in the same form—for
use by our children and our
children's children?
Robinson: Every day peo-
ple take a larger chunk of re-
sources at the expense of other
species. Some of Earth's land-
scapes will have to be used ex-
clusively to meet peoples'
needs. Some can be used to
perpetuate other species.
Some can do both. How we allocate
those uses is our biggest challenge. Will
the world look the same? No. But we can
fashion a sustainable planet.
IW: Some parts of your landscape
don't seem very sustainable.
Robinson: Think of a jigsaw puzzle.
Each piece has different activities with
differing levels of sustainability. But all
the pieces relate together to work as one
sustainable whole. If those pieces don't
fit together, the whole thing doesn't
work.
IW: How do the pieces fit together?
Robinson: Wilderness areas would be
sanctuaries for wildlife. Agricultural and
industrial areas would be productive for
people, driving the engines of national
economies. Extractive areas would allow
natural resources—timber, wildlife, non-
timber products—to be harvested.
Wilderness and extractive areas would
not be as productive as agricultural or in-
, dustrial areas, but they would subsidize
those areas with raw materials and genet-

ic resources. They would provide the es-
sential ecosystem functions—cleaning
the air and water, buffering local cli-
mates—that would keep the whole sys-
tem working. So even if the agricultural
and urban centers, by themselves, would
not be sustainable, the landscape as a
whole would be.
IW: Does this mean our future world
will have room for only swatches of wild
land?
Robinson: That's right. To save
species, we need to preserve reservoirs of
wild land, from cloud forests in the
Andes to coral reefs off Australia. To
feed growing numbers of pec
pie, we will need areas of in
tense agriculture—which wi
never be sustainable per se
What we've got to think abou
is how to integrate the differ
ent swatches.
IW: What about those ex
tractive areas you mentioned'
Robinson: These parts o
the sustainable landscapi
would still be recognizable a
natural systems. They, too
would help preserve specie?
and they would maintain eco
logical integrity and serve eco
logical functions like protect
ing watersheds. But extractivi
areas—which might includi
sections of rain forest when
indigenous people gather nut
and other forest products, fo
instance—might be degradec
and they wouldn't be as pro
ductive for humans as areas o
intensive agriculture.
IW: If we don't come t<
terms with your carved-u
world, what will that mean fo
wildlife? What are we going to lose b;
the year 2020?
Robinson: We are losing species at j
very fast rate at the present time, but th(
average person probably couldn't nami
many of them. Most of those species ten<
to be relatively small with limited geo
graphic ranges and restricted to very spe
cific types of habitat. Within the next 2(
or 30 years, many species which peoph
are more familiar with will be gone o;
very close to extinction. My guess is tha
many of the big charismatic animals-
elephants and grizzly bears—will still b<
around, but their role in their ecosysten
will have long since gone.
IW: And tigers? Would they be anoth
er example?
Robinson: Exactly. With large carni
vores—tigers, jaguars—you are dealing
with species which naturally tend to live
at relatively low densities. To survive
they need big areas. They also compete
with human beings, and probably the;
will be restricted to only a few preserves

USING WILD RESOURCES
"Sustainable use doesn 't work for all species
or in all habitats.... We need to focus our activity on those systems
which people can best harness for their needs."
IW: What about pandas?
Robinson: Pandas are habitat
specialists. They require forest
habitats with a lot of bamboo,
and it is very very difficult to
maintain such forests in China,
where they live.
IW: And rhinos? The same sit-
uation?
Robinson: Every species has
different pressures on it. In the
case of rhinos, you're dealing
with hunting for their horns.
Probably within 20 to 30 years,
the only rhinos left will be in
highly protected sanctuaries. For
all intents and purposes, their role
in natural habitats will no longer
exist.
IW: How about people by the
year 2020? There are likely to be
eight and a half billion of us, or
more. Shouldn't our species be
the beneficiary of whatever we
decide about the wilderness?
Robinson: We do have an
obligation to our fellow human
beings. We also have an obliga-
tion to our fellow species. What
we are striving for is to reach a
balance between human resource
consumption and the need to pre-
serve our world's biodiversity. We're not
just concerned with supporting the great-
est number of human beings at the great-
est quality of life; we're seeking to pre-
serve the rest of the biota for its own
sake and for the sake of future genera-
tions of people.
IW: When we're making trade-offs
and balancing off different uses, are we
limited in our choices by what natural
systems are capable of producing?
Robinson: Areas of high biological di-
versity—tropical forests, for instance—
are generally not very productive for peo-
ple. If you look at savannas, you're
talking about habitats which are much
more productive and can be more easily
exploited. But there are also global lim-
its. At the minute, we are already seques-
tering 40 percent of the world's net pri-
mary productivity—the total production
of all forests, all cropland, all pasture, all

simple ecosystems than complex ones.

plants—to support human beings. At the
same time, we're trying to raise, not just
maintain, the quality of life of all people.
Simple mathematics will tell you that
there is not enough biological potential to
support that kind of aspiration. There are
not enough resources to go around.
IW: What happens when people in-
crease their use of a biological system?
Robinson: You lose some of the diver-
sity of plants and animals. Look at tropi-
cal forests. People tend to cut down the
trees in them to create pasture or
cropland. The forest then be-
comes a system which is much
less biologically diverse but much
more productive for human be
ings. But many ecosystems, even
if altered by people, still have lim-
ited productivity. Tropical forests,
for example, exist on very thin
soils, and most of the biomass is
tied up in the forest itself. Yes,
you can convert a tropical forest
to pasture, but it is a pretty poor
pasture.
IW: If systems like tropical
forests are biologically diverse
and also less productive for peo-
ple, doesn't that suggest that we
ought to protect them rather than
exploit them?
Robinson: First, let me sa>
that we should aim to protect rep-
resentative pieces of all ecosys-
tems. But then I would also argue
that highly diverse systems with
many species—like tropical
forests and coral reefs—should
get the greatest protection. Pro-
tection will tend to be the be
use of those systems.
IW: So some systems—gras
lands, for example—can be ex-
ploited more economically and are there-
fore better suited for human use?
Robinson: Yes. We need to focus our
developmental activity on those systems
which people can best harness for thei;
needs.
IW: Are you arguing that the popular
idea of sustainable use of wildlife—using
excess animals to benefit people—doesn''.
always work?
Robinson: It doesn't work for "all
species or in all habitats. Sustainable use
is more likely where you have a high bio-
logical potential. Many marine system<
for instance, support highly productive
fisheries. Ocean currents form great cer,
ters of nutrients, which support great
concentrations of fish. Those can be ex-
ploited by people.
IW: Can you provide other examples /

southern Africa, people
have developed a system to
crop wildlife. They're ex-
ploiting those wildlife sys-
tems, and they're doing it
in a way which has the po-
tential to be sustainable.
IW: You're talking
about harvesting meat for
local people?
Robinson: I'm talking
about harvesting meat for
local people, about safari
hunting, about commercial
harvesting of certain spe-
cies. In theory, elephant
populations could be har-
vested sustainably for,
meat, hides and ivory.
IW: What about outside
Africa?
Robinson: The Russian
steppes are highly produc-
tive. The saiga antelope has
been sustainably harvested
there for a thousand years,
all the way back to Genghis
Khan. Here is a system
where much of the bio-
mass, or total living matter, is tied up in a
high-density species. If properly managed
and regulated, this is a species that can
be managed sustainably.
IW: What about capybara, the big ro-
dents of Venezuela?
Robinson: A number of species can
be harvested sustainably in the llanos of
Colombia and Venezuela. Small croco-
diles called caiman, which exist in very
high density there, have been exploited
for hundreds of years. In addition, the
productivity of these systems is sufficient
to maintain both subsistence and com-
mercial harvests of anaconda, tegu
lizards and the capybara you mentioned.
IW: So using wildlife may work in
some areas but not in others?
Robinson: Right. Developing sustain-
able-use systems in Asia, for example,
has proven to be extremely difficult.
Wildlife densities in many Asian tropical
forest areas are very, very low, and sus-
, tainable-use systems have not tended to
work well in that part of the world.
Mirrors of their vibrant backdrops,
a longnose hawkfish (above) flits past
a gorgonian coral on a reef in Fiji,
and a poison-dart frog rests in a Costa
Rican rain forest (right). Coral reefs
and rain forests warrant protection
because both are biologically diverse
and of limited economic use to people.
IW: And certain kinds of species lend
themselves more to human use?
Robinson: If you are interested in har-
vesting animals, you are more likely to
succeed if you are working with grass-
eaters, which occur at much higher den-
sities than do meat-eating animals and in
less diverse systems. Harvesting an-
telopes on an African savanna may be
very sustainable. But exploitation of spot-
ted cat skins from tropical forests is
going to be very difficult.
IW: If you're right that our future will
include a fragmented landscape that pro-
vides a balance between resource protec-
tion and resource use, the
aren't we really definir
that balance right now?
Robinson: That's righ
We would all like to i
crease the standard of li
ing and quality of life of i
the peoples in the wor
while at the same tirr
maintaining our natural r
sources for future gener,
tions. The question is:'
what extent will we have
sacrifice some of our eci
nomic aspirations to su
port some of our ecologic
aspirations? What we nee
to strive for is neither con
plete utilization nor prese
vation. What we need

IW: And how do we d

Arizona Democrat Bruce Babbitt is
Secretary of the Interior. He has served as
Attorney'General and Governor of his
native state, and President of the League
of Conservation Voters.
How can we best protect this nation's treasure of
biodiversity—forested mountains, mineral-rich
lands of the West, tumbling rivers and the crea-
tures that inhabit these varied landscapes? Perhaps the
answer is best revealed in our mistakes.
Remember the conflict over the endangered snail
darter in the 1970s? In 1973, opponents of the Tellico
Dam on the Little Tennessee River saw this 3-inch fish
as a cudgel to bring down the dam. After snail darters
were discovered near the dam site, opponents persuad-
ed the United States Supreme Court in 1978 that finish-
ing the project would spell doom for the fish. The court
ordered work stopped on the nearly complete, $137-
million project—angering supporters of the dam and
providing ammunition to opponents of the Endangered
Species Act.
Two years later, determined Tennessee legislators con-
vinced Congress to exempt the dam from the Endangered
Species Act, and thousands of acres were flooded. In an
ironic twist to this bitter drama, the snail darter was not
obliterated, and was taken off die endangered-species list
in 1984.
The snail darter battle left a bitter taste in everyone's
mouth and a lingering impression in the public con-
sciousness that protecting endangered species means con-
flict and disruption. What we learned from this experi-
ence is that, ultimately, nobody wins in "us-versus-them,

all-or-nothing" environmental confrontations.
If we truly want to protect biological diversity, we need
to avoid crisis and confrontation. We can't afford to drag
our feet until a species is at the brink of extinction and
then argue about protecting its last small corner of habi-
tat. We need a new approach: one that encourages us to
think ahead and plan for the future; one that encourages
us to look at whole ecosystems and not just tiny parcels of
land; one that stresses compromise and balance between
people and nature.
We don't need new laws to do this. Congress has
passed impressive environmental legislation. We've got to
start using these laws to resolve conflicts.
The protracted slugfest in the Pacific Northwest over
timber production and the northern spotted owl is anoth-
er example of futile confrontation and lack of foresight.
Many believe that this fight is about one creature in trou-
ble. But it is really about a crisis in forest management
that foreshadowed a much broader breakdown in the
region's ecological balance and economy. It took a federal
judge's injunction to get everyone to sit down together
and talk about the issue.
That's what the Clinton administration's forest confer-
ence last spring was all about. During three days of hear-
ings in April, timber industry representatives testified that
restrictions on logging in the Pacific Northwest forest
would cost tens of thousands of jobs. Environmentalists
stated that the 3 million acres of old-growth trees not yet
cut should be preserved as one of the last remnants of this
country's ancient forests.
In an effort to reach a balance, the administration
issued a plan last summer to permit timber harvesting in
old-growth forests while protecting the ecosystem. This
plan should have been hammered out 20 years ago.
Instead, the players waited until the crisis was white-hot.
The Endangered Species Act often has been at the cen-
ter of these maelstroms. Critics charge the act is an eco-
weapon out of control, but 1 consider this legislation an
extraordinary achievement, probably the most revolution-
ary environmental law of this century. It explicitly says
that when a species begins the downward slide toward
extinction, the response will be a habitat protection plan
that will make it a criminal offense to take that species or
its habitat.
Eco-showdowns get most of the publicity, but we've
had some great successes with this law: the bald eagle, the
peregrine falcon, the American alligator and more. My
take on the Endangered Species Act is that we haven't
even come close to working with the authority, the con-
cepts and the flexibility contained in the Act to avoid
environmental cnses.
One place where we're trying to do better is southern
California. There, a small blue-gray songbird, the gnat-
catcher, is struggling to keep a foothold. Developers view
the 250,000 acres of coastal sage scrub where the bird
lives as some of the best unbuilt real estate left in south-
ern California. But the gnatcatcher prizes it, too. The bird
rarely ventures more than a few acres away from its nest-
ing site, and when it's threatened, it hides deep in the
brush. It will stay in its habitat even if it means getting
bulldozed.
To avoid a "people-versus-songbird" conflict, the state
of California is working with developers and conserva-
tionists in a novel approach called the Natural
Communities Conservation Planning Program. Since
1991, government officials have been meeting with all
sides to identify and preserve enough of the coastal sage
habitat to support the gnatcatcher and other rare species.
While the planning effort is under way, the state pro-
gram allows developers to build on a small part of the
land as long as they agree to set aside preserves or restore
portions of habitat when they're identified. An added ben-
efit to this approach is that it can help species such as the
cactus wren that share gnatcatcher habitat—before they,
too, start sliding towards extinction.
To assist California's effort, the federal government last
March listed the gnatcatcher as threatened, rather than
endangered. In that way, strict federal regulations for
endangered species do not overwhelm the planning
process. If the California groups fail to reach scientifically
sound agreements or lag behind timetables to complete
their work, the federal government will take over the
process.
This is the first time in the history of the Endangerec
Species Act that we have listed a species and then steppec
back to defer to the state's planning process. The outcome
is by no means clear, but we want to make it work.
There is another example where cooperation can pro
mote both biodiversity and jobs. The federal governmen
and Georgia-Pacific Corporation—the nation's bigges
forest products company—have reached a precedent-set
ting agreement to help the endangered red-cockade(
woodpecker. Georgia-Pacific has devised plans to protec
the 300 to 400 woodpeckers that reside and forage 01
about 56,000 of the 4.2 million acres of company-owne<
pine forests in the South.
The company will halt logging on land that contain
colonies of woodpeckers, which live in cavities hammere
into old living pine trees. In addition, Georgia-Pacific wi
establish buffer zones around each colony where timbe
will be selectively harvested, and will prevent road-buik
ing near the birds' colonies.
l« HATUfl CONSfftVANCr • J.A,\ L'ARl /FEBRl'AR > 1 9 9 •»
-------
In return for taking steps to protect the woodpecker,
the company can continue logging without restrictions
imposed by the Endangered Species Act. The agreement is
a demonstration that it's possible to find a balance
between the imperative to create jobs in forest production
and the imperative to protect the environment.
If we're going to protect whole ecosystems, rather than
just single species or pieces of habitat, we need a base of
rigorous, comprehensive science. Strong research will
help us see more clearly what the problems are and give
us flexibility to act before a cusis. To help accomplish
this, we are establishing a new bureau at the Interior
Department: The National Biological Survey.
Modeled after the century-old U.S. Geological Survey,
the biological survey will draw scientists from the depart-
ment's different bureaus to coordinate ongoing studies
and to avoid duplicate or fragmented research projects.
The survey's emphasis will be basic research and will
focus on areas already found in existing Department of
Interior programs.
For example, the survey will oversee studies on the
loss of wetlands in coastal Louisiana, how to manage
streams and riparian habitats in the Pacific Northwest and
the impact of offshore oil drilling. In addition, the survey
will examine how to save declining species from extinc-
tion, and how to curtail the destructive impacts of non-
native organisms that have invaded an ecosystem.
A new mission for the survey and one of its most
important tasks will be to examine the status and trends
for all U.S. wildlife habitats. The survey then could report
regularly on the abundance, distribution and health of the
nation's ecosystems.
Besides bolstering our scientific base, we need to
reform our specific missions in resource management at
the Department of Interior. For instance, the Bureau of
Reclamation, responsible for much of the dam construc-
tion in the West, should look at how to allocate water
without turning to big new construction projects.
We also need to institute more realistic market pric-
ing of our resources. Those who graze cattle on grass-
lands, or extract hard rock minerals, or use water from
a federal reservoir, or cut timber in a national forest
should pay their fair share to use those resources and
restore the land. Market pricing encourages conserva-
tion and wise use of limited resources.
The American conservation movement has been
through two important eras. The first was in the time of
Teddy Roosevelt, who helped create the land management
ethic. Roosevelt summed up this ethic by saying, "The
nation behaves well if it treats the natural resources as
assets which it must turn over to the next generation
increased and not impaired in value."
The second era was in the 1960s and 1970s—a penod
of heightened concern about the unchecked use of toxic
chemicals and industrial pollution. Stimulated in part by
Rachel Carson's book Silent Spring, a clarion call about
the dangers of pesticides such as DDT, the government
assumed a greater role in regulating and limiting pollu-
tants in our soil and water.
Now, on the eve of the millennium, we are entering a
third era that is infinitely more complex because it
demands that we strike a balance, that we make peace
with the natural environment.
As the one species dial dominates the world, we must
make space for the rest of creation to play its assigned role
on this planet. It can't be "us versus them." Ultimately,
we'll all lose. But if we learn to live more lightly on the
land, we'll all win. Q

Dear Mr. Reilly:
Over a year and a half ago, you asked the Science Advisory Board to review
1987 report. Unfinished Business: A Comparative Assessment of fnvironmenta
/ems, and then assess and compare different environmental risks m light of th
recent scientific data. You also asked us to examine strategies for reducing maj<
and to recommend improved methodologies for assessing and comparing n
risk reduction options in the future. This report and its three appendices hav
prepared in response to your request.
To undertake this project, the Science Advisory Board created a special R
Risk Reduction Strategies Committee composed of 39 distinguished scientn
other experts from academia, state government, industry, and pubfic interest i
The Committee carefully considered the reports written by each of its thre
committees, and the findings and recommendations contained in Reducing Ri
from the work of the Subcommittees and reflect study, discussion, and synthesi;
Committee as a whole. This report has been reviewed by the SAB Executivi
mittee and has been formally approved as an SAB document.
As you are aware, the Science Advisory Board normally reviews scientific rep
the Agency and evaluates them on the basis of scientific and engineenn
However, in this case our review of Unfinished Business and our analysis
reduction options have led us to make findings and recommendations that ar
policy-oriented than is usually the case. We have done this at your request
This report, together with its three appendices, suggests steps that the Environ
Protection Agency should take to improve its own efforts'— and to involve C
and the rest of the country in a collective effort — to reduce environmental r
strongly believe that the Agency should take steps to ensure that this nation use
tools at its disposal in an integrated, targeted approach to protecting human
welfare, and the ecosystem.
This report is only a step along.a long road. We encourage you to lead the \
taking the necessary further steps as soon as possible.

The Concept of Risk
Over tilt past 20 years this countrv has put in place
extensive and detailed government policies to control
a number of environmental problems Smog in
heavily populated areas, the eutropmcanon of lakes,
elevated levels of lead in the blooc ot millions of
children, the threat of cancer from exposure to
pesticide residues in food, and abanaonec drums of
hazardous wastes are a few of the prooiems that
have driven the enactment of more f.an a dozen
major Federal laws and the current pursue and
private expenditure of about S100 billion a vear to
protect the environment.
Those efforts have led to very real nanonal
benefits. The staggering human heairr and ecological
problems apparent throughout eastern Europe
suggest the pnce this country wouu rn- pa vine now
had it not invested heavily m polluter ..ontrots.
Yet despite the demonstrable succe^- or past
nanonal efforts to protect the environment many
national environmental goals sni! have not been
attained. Factors like the growth in automobile use
and common agricultural practices nave caused
nanonal efforts to protect the environment to be less
effective than intended.
Furthermore, with hindsight it is clear that in
many cases those efforts have been inconsistent,
uncoordinated, and thus less effective than they
could have been. The fragmentary nature of U.S.
environmental policy has been evident in three ways:
• In laws. As different environmental problems were
identified, usually because the adverse ettects —
smog in major aties, lack of aquatic life in stream
segments, declining numbers of bald eagles — were
readily apparent, new laws were passed to address
each new problem. However, the tactics and goals of
the different laws were neither consistent nor
coordinated, even if the pollutants to be controlled
were the same. Many laws not passed primarily for
environmental purposes also had ma|or effects on
the environment.
• In Programs. The Environmental Protection Agency
(EPA) was established as the primary Federal agency
responsible for implementing the nation's
environmental Laws. EPA then evolved an
administrative structure wherein each program was
primarily responsible for implementing specific laws.
Consequently, the efforts of the different programs
rarely were coordinated, even if they were "-"*
attempting to control different aspects of the
environmental problem. This problem is
compounded by the fact that EPA is not the'c
agency whose activities affect the environmer
• In Tools. The primary tools used to protect
environment have been controls designed to <
pollutants before they escape from smokestac
tailpipes, or sewer outfalls, and technologies
designed to clean up or destroy pollutants af
have been discharged into the environment. -
so-called "end-of-pipe" controls and remedia
technologies almost always have been apphei
because of Federal, State, or local legal requii
For a number of reasons, this kind of fragr
approach to protecting the environment will
as successful in the future as it has been in t
In this country the most obvious controls aln
have been applied to the most obvious probl
complex and less obvious environmental pro
remain, and the aggregate cost of controlling
problems one-by-one is nsing.
Moreover, this country — and the rest of
world — are facing emerging environmental
problems of unprecedented scope. Populatio
growth and industrial expansion worldwide
straining global ecosystems. Never before in
have human activities threatened to change
atmospheric chemistry to such an extent tha
climate patterns were altered.
Given the diversity, complexity, and scop*
environmental problems of concern today, it
critically important that U.S. environmental
evolves in several fundamental ways. Essen

Pofccyis the concept of environmental nsk Each
environmental problem poses some possibility of
nanrVto human health, the ecology, the economic
system, or the quality of human Sfe. That*.each
problem poses some environmental nsk Risk
assessment is the process by which the form,
dimension, and characteristics of that nsk are
estimated, and risk management is the process by
which the risk is reduced. .... t. ..
The concept of environmental nsk, together with
its related terminology and analytical methodologies,
helps people discuss disparate environmental
problems with a common language. It allows many
environmental problems to be measured and
compared in common terms, and it allows different
risk reduction options to be evaluated from a
common basis. Thus the concept of environmental
risk can help the nation develop environmental
policies in a consistent and systematic way.
Scientists have made some progress in developing
quantitative measures for use in comparing different
nsks to human health. Given sufficient data, such
comparisons are now possible within limits.
Although current ability to assess and quantify
ecological risks is not as well developed, an increased
capacity for comparing different kinds of risks more
systematically would help determine which problems
are most serious and deserving of the most urgent
attention. That capacity would be even more valuable
as the number and senousness of environmental
problems competing for attention and resources
increase.
An improved ability to compare nsks in common
terms would have another value as well: it would
help society choose more wisely among the range of
policy options available for reducing nsks. There are
a number of ways to reduce the automobile
emissions that contnbute to urban smog; there are a
number of ways to decrease human exposure to lead.
The evaluation of relative nsks can help identify the
relative efficiency and effectiveness of different nsk
reduction options.
There are heavy costs involved if society fails to set
environmental prionties based on nsk. If finite
resources are expended on lower-pnonty problems at
the expense of higher-priority nsks, then societv will
face needlessly high risks. If prionties are established
based on the greatest opportunities to reduce nsk,
total risk will be reduced in a more efficient wav,
lessening threats to both public health and local and
global ecosystems.

TheTeii
Recommen
1. EPA should target its environmental protection
efforts on the basis of opportunities for the greatest
risk reduction. Since this country already has taken
the most obvious actions to address the most obvious
environmental problems, EPA needs to set priorities
for future actions so the Agency takes advantage of
the best opportunities for reducing the most serious
remaining risks.
2. EPA should attach as much importance to
reducing ecological risk as it does to reducing
human health risk. Because productive natural
ecosystems are essential to human health and to
sustainable, long-term economic growth, and because
they are intrinsically valuable in their own right, EPA
should be as concerned about protecting ecosystems
as it is about protecting human health.
3. EPA should improve the data and analytical
methodologies that support the assessment,
comparison, and reduction of different
environmental risks. Although setting priorities for
national environmental protection efforts always will
involve subjective judgments and uncertainty, EPA
should work continually to improve the saennfc data
and analytical methodologies mat underpin those
judgments and heip reduce their uncertainty.
4. EPA should reflect risk-baaed priorities in its
strategic planning processes, The Agency's
long-range plans should be driven not so much by
past risk reduction efforts or by existing
programmatic structures, but by ongoing
assessments of remaining environmental risks, the
explicit comparison of mow risks, and the analysis of
opportunities available for reducing risks.

Chapter Two—Findings
1. The Importance of
Unfinished Business
With the publication of Unfinished Business early in
H-34; H-6d 1987, EPA took a bold and much-needed step: it
E-3.Q; E-&0 compared the relative residual risks posed by a range
S-4J of different environmental problems, and thus
suggested an important shirt in national
environmental policy. With that report EPA took the
first step toward relative risk reduction; that is, a
policy that attempts to match Agency and societal
resources to risk.
To produce Unfinished Business EPA brought
together staff from all its program offices for the
explicit purpose of comparing the relative risks of
different environmental problems, regardless of
individual programmatic priorities or responsibilities.
To do that, the EPA staff had to assess
environmental risk in a context broader than
programmatic structure or legislated activities. In
short, they had to put aside considerations of
bureaucratic "turf" in order to rank the problems
they believed most needed society's attention. EPA
should be applauded for the courage and foresight to
undertake a project like Unfinished Business.
Unfinished Business presents useful, preliminary
information for comparing environmental problems,
although in some cases its rankings are a matter of
judgment and cannot be supported fully by existing
data. The Ecology and Welfare Subcommittee
questioned the welfare rankings, because it disagreed
with some of the economic assumptions underlying
those rankings and because of a general lack of
relevant economic data. The Human Health
Subcommittee questioned the accuracy of any
ranking of human health risks at this tune, given the
limited human exposure and chronic toxicity data
currently available. Both Subcommittees observed . ''
that the 31 problems assessed were not derived from
a systematic classification of all environmental
problems, and both suggested alternative and more
comprehensive approaches to classification that
would facilitate a more coherent ranking.
Most of the 31 environmental problems assessed in
Unfinished Business are so broad, and include so mam
toxic and non-toxic agents, that its ranking of
problems cannot be evaluated with rigor or
confidence. Additionally, the authors of Unfinished
Business intentionally defined environmental
problems to correspond to legislation and
programmatic organization. As a result, they
attempted to compare heterogenous mixtures of
pollutants (like air pollutants and drinking water
pollutants) to pollutant sources (like oil spills and
mining waste) to receptors (like consumers and
workers). Yet without a consistent basis for
comparison, such comparisons are tenuous at best
Moreover, because the authors chose to limit the
environmental problems they compared. Unfnn^h\i
Business does not address problems like the loss or
habitat and the decline in genetic diversity, even
though such problems pose very senous risks, and
EPA and other agencies may be able to take actions
to mitigate them. A meaningful ranking of relutitf
environmental risks must include all such nskb,
whether or not laws have been passed or program*.
set up to control them.
A final shortcoming for the authors of Untnu^n-tt
Business was the availability of data. Good data u>
evaluate risks simply did not — and in manv ui-v-
still do not — exist. The EPA staff understanJahK
used their professional judgment to fill the djt.i
gaps. The Subcommittee reports appended u> tm-
overview report document in more detail thv
members' judgments as to the relative strength .mJ
weakness of the data used to support the nsk
rankings in Unfinished Business.
The findings and recommendations described in this overview report have been derived mainly from the reports prepared
by the three Subcommittees of the Relative Risk Reduction Strategies Committee. Those reports, which are included as
appendices to mis report contain detailed information that support and more fully explain the findings and
recommendations. Such information can be found by referring to the sections of the different appendices that arc luted at

2. Problems in
Ranking Risks
As long as there are large gaps in key data sets,
E-3&, E-i2 efforts to evaluate nsk on a consistent, ngorous basis
H-3.0; H-&0 or to define optimum risk reduction strategies
necessarily wUl be incomplete, and the results will be
uncertain. For example, data on human exposure
and on the toxitity of many pollutants are seriously
deficient. In particular, the lack of pertinent exposure
data makes it extremely difficult to assess human
health risks.
Moreover, great uncertainty often is associated
with the data that do exist. Exposure and toxic
response models, the numbers used to quantify
nsks, and variations in individual susceptibility to
risks are often highly uncertain. Without more and
better data, conclusions about relative nsk will be
tenuous and will depend in large measure on
professional judgment.
In addition to the lack of data, methodological
inadequacies also impede the assessment and
comparison of nsk. At this time EPA does not have
an effective, consistent way of identifying
environmental problems in a manner that neither
fragments nor aggregates sources of risk to an extent
that renders comparisons untenable. EPA's current
framework of statutory mandates and program
structure helps to maintain artificial distinctions
among environmental problems, and those
distinctions are conducive neither to sound
evaluation of relative risk nor to selection of the most
effective actions to reduce risk.
In particular, the methodologies currently used to
estimate the benefits of risk reduction activities are
inadequate and inappropriate. For example, a
methodology that presumes the future value of an
ecological resource necessarily must be less than its
present value will not be a useful analytical t
sustaining economic development over the Ic
term. The standard practice of discounting ft
resource values is inappropriate, and it resul
policies that lead to the depletion of irreplace
natural resources.
Reliance on "willingness to pay" and simil.
techniques commonly used in economic anal;
distorted current understanding of the value
natural resources. While some people may n<
about wetlands and assign no value to their
existence, such areas still provide valuable ec
services to this and future generations. Whilt
people are likely to care about and be willing
for plankton and fungi, such organisms play
role in sustaining economically valuable ecos
An additional difficulty entailed in any att<
compare and rank environmental nsks is the
inevitable value judgments that must be mac
example, are health nsks posed to the aged r
less serious than health nsks posed to infant;
risks of cancer more or less serious than thre
reproductive processes? Comparing the nsks
to human populations with the risks posed t
ecosystems may be even more difficult. It se<
that subjective values always will — and sho
influence the ranking of relative environmen
no matter how sophisticated the technical an
analytical tools become.
-------
3. The Extraordinary
Value of Natural
Ecosystems
Natural ecosystems like forests, wetlands, and
E-SJt oceans are extraordinarily valuable. Those
ecosystems contain economically valuable natural
resources that feed, clothe, and house the human
race. They act as sinks that, to a certain extent,
absorb and neutralize the pollutants generated by
human activity. Although natural ecosystems — and
the linkages among them — are not completely
understood, there is no doubt that over time the
quality of human life declines as the quality of
natural ecosystems declines.
The value of natural ecosystems is not limited to
their immediate utility to humans. They have an
intrinsic, moral value that must be measured in its
own terms and protected for its own sake.
However, over the past 20 years and especially
over the past decade, EPA has paid too little
attention to natural ecosystems. The Agency has
considered the protection of public health to be its
primary mission, and it has been less concerned
about risks posed to ecosystems. The Agency's
relative lack of concern reflects society's views as
expressed in environmental legislation; ecological
degradation probably is seen as a less senous
problem because it is often subtle, long-term, and
cumulative. But for whatever reason, this imbalance
is a manifest, if inadvertent, part of current national
environmental policy.
EPA's response to human health risks as comt
to ecological risks is inappropriate, because, in th
real world, there is little distinction between the u
Over the long term, ecological degradation either
directly or indirectly degrades human health and
economy. For example, as the extent and quality ^,
saltwater estuanes decline, both human health and
local economies can suffer. As soils erode, forests.
farmlands, and waterways can become less
productive. And while the loss of species may not tx
noticed immediately, over time the decline in genetu
diversity has implications for the future health of th«
human race.
In short, human health and welfare ultimately reis
upon the life support systems and natural resources
provided by healthy ecosystems. Moreover, human
beings are part of an interconnected and
interdependent global ecosystem, and past
expenence has shown that change in one part of the
system often affects other parts in unexpected wavs
National efforts to evaluate relative environmental
risks should recognize the vital links between huma
life and natural ecosystems. Up to this point, thev
have not.

4. Time, Space,
and Risk
E-13; E-7JO
S-12
While the data needed to support firm rankings of
nsk were found to be limited, the RRRSC identified a
number of important factors that must be considered
in any assessment or ranking of the hsk associated
with a particular environmental problem. Those
factors include the number of people and other
organisms exposed to the risk, the likelihood of the
environmental problem actually occurring among
those exposed, and the severity of the effects,
including the economic losses and other damages
involved, if it does occur.
In addition, two other aspects of potential
environmental problems — i.e., their temporal and
spatial dimensions — also must be given
considerable weight in any analysis of relative
environmental risk. Consideration of time and space
can help guide judgments about relative risks in the
absence of complete data.
The temporal dimension of an environmental
problem is the length of time over which the
problem is caused, recognized, and mitigated. For
some environmental problems the temporal
dimension can be very long. For example, the
chronic human health effects of air or water pollution
may become apparent only after many yean of
exposure. It may take decades of human activity to
begin to change the global climate, and more decades
may pass before the effects of human activity on the
global climate are dearly understood. Some
pollutants can persist in the environment — and thus
pose environmental risks — indefinitely. And it may
take decades or even centuries before depleted
species of wildlife recover from the loss of habitat, if
recovery is possible at all.
The spatial dimension of an environmental
problem is the extent of the geographical area that is
affected by it. Some environmental problems, like
elevated levels of radon, may be limited to the
basements of some homes, while problems like
stratospheric ozone depletion can affect the entire
globe. And some global problems, like the loss of
genetic diversity, can be caused by human activities
in reiattvrijr limited geographical areas.
The time and space dimensions of environirx
problems should weigh heavily in any compari
relative environmental risks. For example, if
long-lived pollutants like DDT and PCBs can h
concentrated in the food chain and pose a thre
future as well as present human and ecological
health, those future risks should be taken into
account when relative risks are compared. Simi
if global climate change or stratospheric ozone
depletion has the potential to affect the health .
economic well-being of virtually everyone on ft
now and in the future, the extent and duration
risk should suggest a relatively high-risk rankir

However, some changes are either permanent (

5. The Links Between
Risk and Choice
It is sometimes tempting to think simplistically about
S-12 the sources of environmental risk as being a
particular industry, a particular product, or a
particular pollutant. Conceptually, smokestacks can
be controlled, products modified', and pollutants
banned with relative ease.
But the sources of environmental risk are much
more diverse and complicated than that. In fact, the
sources of risk often are to be found in the
day-to-day choices made by individuals,
communities, and businesses. And many kinds of
environmental risk will not be reduced substantially,
especially over the long term, if past patterns of
individual, community, and business choices do not
change in light of the relative risks posed by those
choices.
In a sense, the very existence of the human race
inevitably poses some level of environmental nsk.
People necessarily generate wastes, both as
individuals and through aggregate economic
activities. People necessarily destroy or infringe upon
some natural Habitats when they construct their own.
Individuals either increase or lessen environmental
risk depending on which consumer products they
buy, how they design their homes, and whether they
walk or drive to work. Society affects environmental
risk at the local level through building codes and
zoning laws and at the national level through tax,
energy, and agricultural policies.
But all these activities involve choice, and the
environmental risks posed by many human activities
can be reduced sharply if different choices are made.
So one of the most important questions facing society
is how to influence and shape individual,
community, and business choices so that
environmental risks are reduced.
Choice is influenced by a number of factory,
including education and ethics. Some people may
choose to purchase certain consumer products
because of a genuine concern about the
environmental effects of their personal buying
patterns. Similarly, some businesses may redesign
production processes to eliminate pollution because
of a desire to be perceived as corporate "good
citizens."
Economic incentives are also important tools for
inducing particular kinds of choices. When the price
of energy rises, consumers are likely to buy more
fuel-efficient vehicles and weatherize their'homes,
while plant managers have an added incentive to
purchase more energy-efficient equipment. Full
pricing of municipal services can give people an
incentive to recycle their household wastes and
conserve water.
Laws and regulations, of course, are very effective
at shaping individual and social choices. Local
zoning laws can change the pattern of economic
development in a community and limit where homes
can be built. Local, State, and Federal procurement
regulations can have a substantial effect on the
development of markets for recycled products.
Projected future growth in population and
economic activity could add enormously to the
environmental risks faced in this country and around
the world. But growth and reductions in
environmental risk are not necessarily incompatible,
if past patterns of individual, community, and
business choice can change. In national efforts to
assess, compare, and control relative risks, the
importance of those choices — and the policy options
available to influence those choices — should not be
overlooked.

6. Public Perceptions
of Risk
S-B.4
Public opinion polls taken over the past several years
confirm that people are more worried about
environmental problems now than they were 20
years ago when the first wave of environmental
concern led to major changes in national policy. But
the areas of greatest concern to the public today are
not necessarily those problems identified in
Unfinished Business. In other words, the remaining
and emerging environmental risks considered most
serious by the general public today are different from
those considered most serious by the technical
professionals charged with reducing environmental
risk.
This dichotomy between public perceptions and
professional understanding of environmental risk
presents an enormous challenge to a pluralistic,
democratic country. A Federal agency like EPA must
be sensitive to public concerns about environmental
problems. In fact, since public concerns tend to drive
national legislation. Federal environmental laws are
more reflective of public perceptions of risk than of
scientific understanding of risk. Consequently, EPA's
budget and staff resources tend to be directed at
those environmental problems perceived to be most
serious by the general public.
Yet if national resources are to be used most
effectively to promote environmental quality, then
such resources must be aimed at those
environmental problems that pose the greatest risks.
The ability to match resources to risks will mi
the success of national policies to protect the
environment.
One obvious way to bridge this dichotomy
be to improve the public's understanding of t
scientific and technical aspects of environmer
while improving scientists' understanding of
basis of public concern. Public perceptions of
environmental risk tend to incorporate deeph
subjective values, like justice and equity, that
although difficult to quantify, reflect importa
elements of the quality of life that govemmer
bound to protect. Moreover, since the saenh
understanding of any environmental problem
likely to evolve as the science improves, and
environmental policy necessarily embodies SL
values, scientific understanding should not fcx
sole determinant of environmental policy.
Therefore, EPA must be prepared to listen
carefully to the public's perceptions of nsk.
Moreover, EPA should balance those percept
with current scientific understanding as the f
develops long-term risk reduction strategies.

7. Relatively High-Risk
Environmental Problems
E4&, E-6A-
H-5&, H-7.0
The RRRSC not only reviewed the risk rankings
contained in Unfinished Business, but it also identified
several environmental problems as relatively
high-risk, based on available scientific data and
technical understanding. This effort was challenging
for a number of reasons. Ecological, health, and
welfare risks can be manifested in a number of
different endpoints; it is difficult to compare risks
with widely different time scales and spatial
dimensions; because of data gaps and methodological
inadequacies, it is rarely feasible to quantify total
risk. In other words, the RRRSC faced mariv of the
same hurdles that faced the authors of i
Business when they developed their risk ranking
Consequently, the RRRSC did not rank risks i
same manner a's Unfinished Business did. The Eci
and Welfare Subcommittee grouped environment
problems into high-, medium-, and low-risk areas;,
the Human Health Subcommittee identified
environmental problem areas where existing data
indicated that risks could be relatively high.
Additional data might identify additional high-risk
problems. Both Subcommittees developed their
assessments in light of the latest scientific and
technical knowledge and using their best profession
judgment, and both caution that their assessments
are Based on incomplete and often inadequate
knowledge about 1) the extent of human and
ecological exposures to pollutants and 2)
exposure-response relationships.
Risks To The Natural Ecology And Human Welfare
The Ecology and Welfare Subcommittee identified areas
of relatively high, medium, and low risk, despite gaps
in the relevant data. The four environmental problems
that it considered to be relatively high-risk are likeJy to
be considered nigh-risk even after data and analytical
methodologies are improved, because the geographic
scale of all four is very large (regional to global), and
because the time that could be required to mitigate all
four is very long, and some effects are irreversible.
The Ecology and Welfare Subcommittee did not limit
their assessment to the environmental problems listed
in Unfinished Business. The order of problems listed
within each of the three different risk groups shown
below is not meant to imply a ranking.
Relatively High-Ruk Problem*
• Habitat Alteration and Destruction
Humans are altering and destroying natural
habitats in many puces worldwide, e.g., by the
draining and degradation of wetlands, soft
erosion, and the deforestation of tropical and
tempciaic rain forests.

ozone-depleting gases are thinning the earth's
stratospheric ozone layer, more ultraviolet
radiation is reaching the earth's surface, thus
stressing many kinds of organisms.

Chapter Three—Recommendations
1. EPA Should Taiwt Its Environmental Protection
Efforts On The Iwis Of Opportunities For The
Greatest Risk Reduction
Seen in its historical context, the ad hoc development
of U.S. national environmental policy is
understandable. Yet 20 years of experience in
developing and implementing environmental policy
has demonstrated that not all environmental
problems are equally serious, and not all remediation
efforts are equally urgent. The nation cannot do
everything at once. In national efforts to protect the
environment, the most obvious steps have been
taken to reduce the most obvious risks. Now
environmental priorities must be set.
In order to set priorities for reducing
environmental risks, EPA must weigh the relative
risks posed by different environmental problems,
determine if there are cost-effective opportunities for
reducing those risks, and then identify the most
cost-effective risk reduction options. This effort
should build on the analytical process begun in
Unfinished Business and in this report and its
appendices.
However, the SAB recognizes that risk analyses
always will be imperfect tools. No matter how much
the data and methodologies are improved. EPA's
decisions to direct specific actions at specific risks
will entail a large measure of subjective judgment.
Yet the SAB believes that relative risk data and risk
assessment techniques should inform that judgment
as much as possible. In short, EPA programs should
be shaped and guided by the principle of relative risk
reduction, and all available risk data and the most
advanced risk assessment and comparison
methodologies should be incorporated explici
the Agency's decisionmaking process.
In order to implement a risk-based action a
EPA must take several essential steps. It mus
articulate to its own employees and to the gei
public the fact that it intends to set priorities
action based on opportunities for relative nsk
reduction. Next the Agency must establish an
process for incorporating those consideration:
long-term planning and budget processes. Fir
the Agency must act on those priorities.
In practice, of course, EPA's activities are d
by the laws that it is required to administer. I
also has a responsibility to respond to public
concerns about an environmental problem, nc
how limited the risk may seem to be. Howevi
should not limit its risk comparison efforts to
environmental problems it is required bv law
mitigate. The risks posed by other problems a
potential problems — like the loss of biologic
diversity — must be compared and ranked as
Simply stated, EPA is responsible for prote<
the environment, not just for implementing
environmental law. Thus the Agency should
and compare the universe of environmental r
then take the initiative to address the most s<
risks, whether or not Agency action is requiri
specifically by law.
16
-------
2. EPA Should Attach As Much Importance To
Reducing Ecological Risk As It Does To Reducing
Human Health Risk
E-LO
Largely because of the requirements of the laws it
administers, EPA has tended to pay far more
attention to protecting human health and welfare
than to protecting the ecology. Indeed, during the
1980s EPA's agenda was dominated by concerns
about the effects of toxic chemicals on human health.
Yet from the perspective of risk there are strong
linkages between human health and the health of
wetlands, forests, oceans, and estuaries. Most
human activities that pose significant ecological risks
— for example, the effects of agricultural activities on
wetlands — pose direct or indirect human health
risks as well. Likewise, actions taken to reduce
pollution and thus improve human health usually
improve various aspects of ecological quality.
These very close linkages between human health
and ecological health should be reflected in national
environmental policy. When EPA compares the risks
posed by different environmental problems in order
to set priorities for Agency action, the risks posed to
ecological systems must be an important part of the
equation.
This recommendation is not meant to imply the
relative value of human life vis a vis plant or animal
life. Rather, it is meant to reflect in national
environmental policy the very strong ties between alt -
forms of life on this planet. Ecological systems like
the atmosphere, oceans, and wetlands have a limite.
capacity for absorbing the environmental degradation
caused'by human activities. After that capacity is
exceeded", it is only a matter of time before those 3
ecosystems begin to deteriorate and human health
and welfare begin to suffer.
In short, beyond their importance for protecting
plant and animal life and preserving biodiversity,
healthy ecosystems are a prerequisite to healthy
humans and prosperous economies. Although
ecological damage may not become apparent for
years, society should not be blind to the fact that
damage is occurring and the losses will be felt, sooner
or later, by humans. Moreover, when species and
habitat are depleted, ecological health may recover
only with great difficulty, if recovery is possible at
all.
Thus EPA's risk-based priorities for action should
reflect an appropriate balance between ecological.
human health, and welfare concerns. Furthermore.
the Agency should communicate to the general
public a clear message that it considers ecological
risks to be just as serious as human health and
welfare risks, because of the inherent value of
ecological systems and their strong links to human
healt"
17
-------
10. EPA Should Develop Improved Methods To
Value Natural Resources And To Account For
Long-Term Environmental Effects In Its
Economic Analyses
Traditional forms of economic analysis, as applied to
the costs and benefits of economic development and
environmental protection, have systematically
undervalued natural resources. This practice
threatens the world's natural resources — like
estuaries and rainforests — without which the lives
of future generations will be impoverished. The
failure of current analytic techniques to estimate
properly either the full benefits of natural ecosystems
or tne full costs of activities that degrade them too
often has allowed the justification of long-term
ecological degradation for the sake of present gam.
A private company invests its profits to maintain
and increase its capital value. When a company
invests to maintain facilities, expand production, buy
new equipment, and improve tne quality of services'
provided, it protects its long-term health.
In a similar manner, this planet requires certain
investments in order to maintain itself as a healthy
ecosystem and to ensure sustainable, long-term
economic growth. Future generations depend on
those investments, and if they are not made, then
civilization will put itself out of business.
It is necessary and appropriate to conduct
economic analyses of human activities that affect the
environment. But it is essential that such analyses
properly value the long-term, sustained productivity
of natural ecosystems, for that reason, EPA should
undertake a broad national effort to develop
analytical techniques that more adequately assess the
real long-term value of ecosystems, and that support
the identification of the most cost-effective wavs to
reduce risks that threaten long-term, sustained
productivity.
There are a variety of problems with pn.
methods. Many of the problems stem fron
that public goods, such as dean air, are ur
markets and thus are easily — and often—
undervalued in economic analyses. Nation
accounting schemes typically characterize n
generated by activities that deplete or degn
environmental resources as "income" while
consider the resulting depletion of society's
environmental capital assets.
When economists do try to value ecosysti

Key Tools We Have to
Protect Migratory Birds
and Biodiversity
OBJECTIVE:
Introduce students to key tools we have to
protect Neotropical migratory birds and
biodiversity: the Endangered Species Act and
the 1993 Biodiversity Convention.
THEME:
II.
Ill
We have important legal tools that can be
used to help protect migratory birds,
biodiversity, and ensure our own long-term
survival.
CLASS
ACTIVITY:
I.
Introduce the Endangered Species Act, pointing out the
specified purpose, and the framework of the law. This
law involves some complicated provisions. It is not
necessary to delve into the details of the law. It may
be one of the first times, however, that students have
examined the actual text of a law, and so it is a
useful activity to even see what is there, and how it
is organized. Similarly, the 1993 Biodiversity
Convention can be examined and considered by the class.
Discuss the article assigned as Homework reading from
Class #19, "Protecting Biodiversity", which can be used
as an illustration of current issues under the
Endangered Species Act.
Hand out copies of the "Pan American Day and Pan
American Week, 1993", proclamation by the President
(copy in "Handouts", below). Discuss this type of
20-1

Homework for Class #19.
Review the excerpts provided in "Handouts" on the
Endangered Species Act and the Biodiversity Convention,
and select points you wish to bring up during the class
discussion.

§ 1531. Congressional findings and declaration of pur-
poses and policy
(a) Findings
The Congress finds and declares that—
(1) various species of fish, wildlife, and
plants in the United States have been ren-
dered extinct as a consequence of economic
growth and development untempered by ade-
quate concern and conservation;
(2) other species of fish, wildlife, and plants
have been so depleted in numbers that they
are in danger of or threatened with extinc-
tion;
(3) these species of fish, wildlife, and plants
are of esthetic, ecological, educational, his-
torical, recreational, and scientific value to
the Nation and its people;
(4) the United States has pledged itself as a
sovereign state in the international communi-
ty to conserve to the extent practicable the
various species of fish or wildlife and plants
facing extinction, pursuant to—
(A) migratory bird treaties with Canada
and Mexico;
(B) the Migratory and Endangered Bird
Treaty with Japan;
(C) the Convention on Nature Protection
and Wildlife Preservation in the Western
Hemisphere;
(D) the International Convention for the
Northwest Atlantic Fisheries;
(E) the International Convention for the
High Seas Fisheries of the North Pacific
Ocean;
(F) the Convention on International
Trade in Endangered Species of Wild Fauna
and Flora; and
(G) other international agreements.
(5) encouraging the States and other inter-
ested parties, through Federal financial as-
sistance and a system of incentives, to develop
and maintain conservation programs which
meet national and international standards is
a key to meeting the Nation's international
commitments and to better safeguarding, for
the benefit of all citizens, the Nation's herit-
age in fish, wildlife, and plants.
(b) Purposes
The purposes of this chapter are to provide a
means whereby the ecosystems upon which en-
dangered species and threatened species depend
may be conserved, to provide a program for the
conservation of such endangered species and
threatened species, and to take such steps as
may be appropriate to achieve the purposes of
the treaties and conventions set forth in subsec-
tion (a) of this section.
(c) Policy
(1) It is further declared to be the policy of
Congress that all Federal departments and
agencies shall seek to conserve endangered spe-
cies and threatened species and shall utilize
their authorities in furtherance of the purposes
of this chapter.
(2) It is further declared to be the policy of
Congress that Federal agencies shall cooperate
with State and local agencies to resolve water
resource issues in concert with conservation of
endangered species.

"Why Save Neotropical Migratory Birds?"

(This co/u/raMxptores some of the reasons behind all the activities described in the rest of toe Partners
in Flight nem&etter. The reasons for saving neotropical migratory birds are, of course, multifarious-
biological, ecological, aesthetic, economic, philosophical, and even spiritual. As the Partners in Flight
Program broadens its base and begins to have real effects, the question will inevitably be asked: why
save the birds? You don't have to be an avid birder or ornithologist to appreciate the answers.)
With all the irony and

also frustratingly elusive.
Nature provides the basic
materials and energy neces-
sary for all life to survive and
reproduce. Birds play an
important role in the so-
called life-support systems by
keeping in balance the growth
of insects and other prey, by
spreading seeds and in some
cases causing them to germi-
nate, and by providing food
to their predators.

that birds are indicators of

ecosystem health and
the health of our

which, in view of society's

So we can't with certainty
assert that loss of birds or any

and endangers our existence.
Many of us remain convinced,
however, that major ecologi-

not consciously consider the
welfare of other species,
except perhaps as it might
affect our own survival. But
we are endowed with the
potential of a moral con-
science—both a curse
and a blessing, but
most of all an
underused faculty. The
development of a
moral conscience is
directly correlated
with the extent to
which one is truly concerned
for the welfare of "others"—
outside the self (the first
step), outside the family,
outside the nation... and
ultimately outside our own
species. The vanguard of
humanity has just reached this
final moral frontier; the vast
majority scarcely realizes it
exists, or is more likely to
belittle the notion of caring
intrinsically for other species,
especially if it compromises
its own immediate desires or
needs.
This is why it is essential for
us as human beings
to care
about the
welfare of
the rest of
nature. Yes,
there are many
unmet needs in

Neotropical migratory
landbirds probably fit
in both categories.
Many are colorful and aes-
thetically appealing, stars of
the nature-appreciation
sweepstakes. But as a group
they suffer from being out of
sight for over half the year, as
well as from having an
uncatchy name. Even birders
are not apt to think about
what happens to them outside
breeding season. It takes a
moral leap to appreciate their
special existence and the
vicissitudes involved.
As ecologists, then,
we seek to save birds
because we have
reason to believe they
are important to the
ecosystems
upon which
we and all

depend. As human beings, we
strive to save birds, including
neotropical migratory birds,
because we have learned to

The President Pan American Day and Pan American Week, 1993
r
By the President of the United States of America
A Proclamation
Five hundred years after the first Europeans began exploring tho Americas.
it is appropriate to reflect on our hemisphere's unique role in this rapidly
changing world and to rediscover the peoples of the Americas. On Pan
American Day, the people of the Americas pledge to renew the ties that
make our relationship unique. We cherish our hemisphere's proud history
as we look forward to a new era of cooperation between our countries
and cultures.
We have seen remarkable changes around the globe. The defeat of totalitarian-
ism and the sweep of democratic and free market reforms have brought
new opportunities and new challenges to the world. Progress toward political.
economic, and social change has been dramatic in our own hemisphere.
From North to South, more and more citizens of the Americas are enjoying
the benefits of liberty. Fundamental principles of democracy, including re-
spect for human rights, continue to be embraced. It is our hope that all
nations of the Americas will join in this democratic revolution and at
last realize the dream of a hemisphere of democratic nations.
The need for international cooperation is greater than ever, because we
face many difficult issues in this era: drug trafficking, weapons proliferation,
and environmental degradation. Through a renewed partnership between
nations of this hemisphere, we can develop innovative means to combat
such problems, thus ensuring lasting security for future generations.
A century ago, representatives of the nations of this hemisphere met in
Washington to establish the International Union of the American Republics.
Accepting the principles of democracy, peace, security, and prosperity, these
member nations made a firm commitment to mutual cooperation throughout
the hemisphere. Its successor, the Organization of American States, has
furthered this commitment. In the words of the Charter of the Organization
of American States, "[the] historic mission of America is to offer to man
a land of liberty." I applaud and encourage the activity of the Organization
of American States in this pursuit to ensure that worldwide changes create
a hemisphere of peace and prosperity.
We can take great pnde in what the Americas have already achieved. But
there is much work to be done. Ail Americans from North to South should
renew their commitment to fulfilling our forefathers' vision of an inter-
America system. The hemisphere of George Washington and Thomas Jeffer-
son, of Simon Bolivar and Jos6 da San Martin, establishes an example
of freedom for the rest of the world. With democracy as the cornerstone
of a new working partnership, we can achieve a revolutionary level of
cooperation among the countries of America.

laws of the United States, do hereby proclaim Wednesday, April 14, 1993.

BACKGROUND
*
The United Nations Environment Programme (UNEP) first called on Governments to consider
international legal instrument for the conservation and rational use of biological diversity in 19
The following year UNEP established an Ad Hoc Working Group of Experts on Biologi
Diversity, which held three sessions between November 1988 and July 1990. On the basis of
group's final report, UNEP established a Working Group of Legal and Technical Experts
negotiate a convention. This group held two sessions and was then renamed the Intergovemmer
Negotiating Committee for a Convention on Biological Diversity (INC). The INC comple
negotiations for the Convention in five sessions between June 1991 and May 1992.
ISSUES
During the negotiations, contentious issues included: financial aid to enable developing countri
to implement the terms of the Convention; the terms under which industrialized countries woi
have access to genetic materials found mostly in tropical forests in developing countries; the ten
under which developing countries would have access to environmentally sound technology
to new biotechnologies developed from materials found in their tropical forests: and the questi
of ownership and use of patent rights of the biotechnology produced from such materials.
After negotiations were complete, a number of countries expressed reservations on vario
aspects of the Convention but later agreed to sign. The United States did not sign on the grounc
that provisions in the Convention would unduly restrict the biotechnology industry in that countr
