Ocean Pollution. What is pollution? Pollution occurs when an environment is contaminated, or dirtied, by waste, chemicals, trash, and other harmful substances.

Eutrophication What is it?. Eutrophication begins when nutrients such as nitrates and phosphates run off into a body of water.

Ocean Pollution Affects… Ecosystem Public health Recreational water quality Economic viability

The causes of ocean pollution Types Sources Debris Ships; fishing nets; containers; shoreline litter Toxic Fertilizers and pesticides; wastewaters; sewage systems; fuel combustion Oil Shipping; off-shore oil and gas drilling; accidental spills; land activities Metal Metal mining; manufacturing and processing industries

The Impact of Debris Pollution Degrades beaches Entangles marine life causing Drowning Starvation Attack by Predators Destroys Habitats

Debris Pollution Affects Turtles Sea turtles have to surface at regular intervals to breathe. When they get entangled in nets, they fail to make it to the surface and eventually die by drowning. Also, leatherbacks think plastic is a jellyfish.

The Impact of Toxic Pollution Reduces water clarity Alters food chains Creates poison and disease risks Marine life Human health

Nutrient and Pesticide Pollution Toxic algae grows Algae decays Bacteria feed on the dead algae Oxygen level depleted

AND THEN… DEAD ZONE

The Impact of Oil Pollution Organisms and larvae Near-shore marine life Birds Mammals Oil pollution is just not sea-based

The Impact of Metal Pollution Changes reproduction of marine life Suppresses growth in marine life Appears in global food chain

Make Waves to Fight Ocean Pollution Properly dispose of chemicals Use less toxic household items Recycle plastic, glass, paper and electronics Share and make others aware Organize neighborhood/community cleanup Oceanservice.noaa.gov Preventing Ocean Pollution 5/14/2019
