Oil Spills
Oil Pollution and Its Effect on Wildlife"OIL POLLUTION AND ITS EFFECT ON WILDLIFE" Contamination of the oceans by oil spillage is not a rare occurrence. It is happening all over the world every day, fouling coastlines, killing animals and destroying fisheries. In 1987, more than 3.5 million tons of oil were released into the oceans around the world. Out of that only 28 percent of the spillage was accidental; the remaining 72 percent was deliberate, illegal The sources of oil spillage were: A lot of the illegal pollution is caused by cleaning of oil tanks at sea. After they are cleaned the tankers then dump the polluted water, mixed with all the oil residue, Blowouts occurring at oil well heads release huge amounts of oil and gas into the ocean. The drilling vessel IXTOTI released more than 400,000 tons of oil into the Gulf of mexico over a period of 9 months after its well exploded The most publicized of the oil spills are those caused by tanker
Yetthe residue will eventually end up on the beaches. EFFECT ON WILDLIFE: All the migrating seabirds like guillemots, puffins, and razorbills areat risk from oil pollution. In calm waters, floating booms can contain the oil so that itcan be pumped off the surface of the sea into holding tanks. An area that is rich inwildlife is Alaska's Prince William Sound. During migration, they look for calm waterwhere they rest and fish. They removewhat they can and the remaining oil is sprayed with chemicals. Wecan help and reduce oil pollution by returning used motor oil for recyclingrather than pouring it down the drain or burying it in the yard. In these conditions the oil mustbe burned. When a marine animaldies it is usually eaten by other species and then those species getpoisoned too. Whenthe oil coats their fur, otters can't swim or maintain there bodytemperature, they either freeze to death, or drown. The oil that washes to shore on thebeaches where seals and sea lion breed harm these animals as well, anyanimals that get caught in the oil usually die. A lot of oil is released by sewers and rivers. If they had stricter policies dealing with thisactivity this may be avoided.
