Local Harbors and Bays are impacted!

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 of on land.

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.

•Pathogens are found in raw sewage, its a disease-causing 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.

Sewage- The waste matter that passes through sewers.

Effluent- Flowing out or forth; refers to liquid wastewhich 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 IngestionIngestion

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.

EntanglementEntanglement 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 fast-food 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?
