MARINE DEBRIS
Reducing marine debris
means reducing the
amount of waste generated
on land and at sea, and
disposing of it properly.
Volunteer coastal cleanups
and public education efforts
can help reduce the
amount of debris in our
waterways and coastlines.
In 2008, over 183,000
people across the U.S.
participated in beach
cleanups. These cleanup
efforts removed almost four
million pounds of debris
from more than 9,000
miles of coasts, shorelines,
and underwater sites.
Recycling and proper
disposal can significantly
reduce the amounts of
marine debris reaching
oceans and coastal waters.
A great deal more can be
done. You can be part of
the solution.
Marine debris is a problem along shorelines, and in
coastal waters, estuaries, and oceans throughout the world.
Marine debris is any man-made, solid material that enters
our waterways either directly or indirectly. Marine debris
enters our oceans and coasts from a number of land- and
ocean-based sources. More people move near our Nation's
coasts each year, and the production of trash and the
potential for marine debris continues to increase. We need
to better control the disposal of trash and other wastes, or
we will continue to find marine debris in our rivers,
streams, and oceans.
WHAT IS MARINE DEBRIS?
• Marine debris is trash and other
solid material that enters oceans
and coastal waters and often ends
up on our beaches. It is also known
as litter.
• Common types of marine debris
include plastic bags, bottles and
cans, cigarette filters, bottle caps,
and lids.
WHERE DOES MARINE DEBRIS
COME FROM?
• When trash is not recycled or
properly thrown away on land, it can
become marine debris. For
example, trash in the streets can
wash into sewers, storm drains, or
inland rivers and streams when it
rains and can be carried to oceans
and coastal waters.
• People who go to the beach
sometimes leave behind trash.
• Recreational and commercial
fishermen sometimes lose or
discard large fishing nets and lines
in the ocean.
• Ships and recreational boats at sea
sometimes intentionally or
accidentally dump trash directly into
the ocean. Trash from boats may
be thrown, dropped, or blown
overboard.
WHAT DOES MARINE DEBRIS DO
TO THE ENVIRONMENT?
• Trash on the beach can be harmful
to the health and safety of beach
users. It also makes the beach look
ugly and dirty. Dirty beaches
discourage visitors and cause local
beach communities to lose money
from tourism or to spend money on
cleanup efforts.
• Many types of animals, like seals,
sea turtles, birds, fish, and crabs,
can be wounded, strangled, or
unable to swim if they consume or
become entangled in marine debris.
• Marine animals can swallow marine
debris causing suffocation or
starvation. Sea birds have been
known to swallow small plastic
pieces (which look like fish eggs);
and sea turtles have been known to
swallow clear plastic bags (which
look like jellyfish).

WHAT IS EPA DOING TO
PREVENT MARINE DEBRIS?
• EPA and other stakeholders
support the annual International
Coastal Cleanup (ICC),
implemented by Ocean
Conservancy. The ICC currently
involves 50 U.S. states and
territories and 104 countries from
around the world. The ICC is the
largest volunteer environmental
data-gathering effort and cleanup
of coastal and underwater areas in
the world. Thousands of
participants learn the value of
preventing and controlling marine
debris. The ICC takes place on
the third Saturday in September
every year.
• Ocean Conservancy with support
from EPA recently completed the
National Marine Debris Monitoring
Program (NMDMP). The NMDMP
was developed to standardize
marine debris data collection and
assess marine debris sources and
trends in the U.S. NMDMP used
trained volunteers to conduct
monthly marine debris surveys on
designated beaches over a five-
year period. The NMDMP Report
indicates that approximately 49
percent of the marine debris items
collected nationally during the
study originated from land-based
sources, 18 percent from ocean-
based sources, and 33 percent
from general-sources (i.e., items
that originate on land or at sea).
• EPA scientists have conducted
numerous studies to identify types
and sources of marine debris.
EPA also focuses control efforts
on specific sources such as street
litter, storm water runoff, and
industrial wastewater, and
supports recycling programs.
