What is Marine
Debris?
Marine debris is the
solid human made
rubbish that is
discarded at sea or
ends up in the sea
after being disposed

There are many ways
that rubbish can enter
the sea, including:
•dumping of garbage
at sea by ships,
fishing boats and
pleasure craft.
•deliberate
discarding and
accidental loss of
fishing nets at sea.

Also:
 Litter left on beaches
by picnickers.
Escape of litter from
coastal rubbish dumps.
Drains and sewage
systems that empty
into the sea.

Sewage- The waste matter that
passes through sewers.
•Pathogens are found in raw sewage, its a diseasecausing viruses and bacteria. It can cause serious
health threats to people and animals, that’s why its
unsafe to go swimming, boating, and shell fishing.

EffluentFlowing out or
forth; refers to
liquid waste
which comes
from sewage
treatment plants.

Eutrophication - Caused by the
increase in an ecosystem of chemical
nutrients, typically compounds
containing nitrogen or phosphorus.
Algae Bloom- A relatively rapid increase in
the population of (usually) phytoplankton
algae in an aquatic system.

Red Tide - caused by a population
explosion of dinoflagellates.

Some dinoflagellates give off a
poison as a waste product.

Bycatch- Unwanted marine
creatures that are caught in the
nets while fishing for another
species.

•Ghost fishing is the term used for lost or abandoned
fishing gear that continues to catch fish or anything else
that goes into the net. It is environmentally deleterious
and the fish caught is wasted.

Entanglement and Ingestion
Ingestion
Marine species confuse plastic bags, rubber,
balloons and confectionery wrappers with prey
and ingest them. The debris usually causes a
physical blockage in the digestive system, leading
to painful internal injuries.
http://www.environment.gov.au/biodiversity/threatened/ktp/marine-debris.html
Entanglement
Entanglement in marine debris can cause
restricted mobility, starvation, infection,
amputation, drowning and smothering.

Entanglement and Ingestion
X-ray of turtles being treated at a clinic in
Florida yielded contents in just one turtle
that were found to be balloons and a fastfood latex glove.

Invasive Species- A species is regarded as invasive if it
has been introduced by human action to a location, area,
or region where it did not previously occur naturally.

Sustainability refers to the potential longevity
of vital human ecological support systems.
http://www.wairc.govt.nz/enviroinfo/indicators/community/sustainability/images/sustainability.gif
Sustainable means that something can
continue indefinitely without running out of
materials or energy.

Why do we care about having sustainable
ecosystems?
