Oil spills are devastating to the environment. Oil once spilled onto the ocean forms a thick layer called the slick, which depending on the weather can split or get thinned out further to become the sheen. An oil spill far off the coast can be carried to the coastline due to wave action and can therefore affect coastal marine life. Coastal spills, unless cleaned up will stay around until it is broken down by weather or decomposed by bacteria - this takes a very long time. The gooey black tar-like substance coats everything it comes to contact with. On the surface of water, it is not only toxic but also cuts of oxygen supply to the waters below.
Coastlines and estuaries act as important nesting grounds, marine nurseries and oil spills in these areas prove devastating to birds, animals, juvenile fish, larvae and reefs. Microscopic diatoms and plankton are most severely affected and so are organisms like mussels, clams, crabs, other arthropods and burrowing animals. Birds and marine mammals when coated with oil can die by ingesting the oil trying to clean themselves or due to the toxic chemicals present in the oil. The effects of a spill this size might damage the ecosystem for years to come according to some biologists.
Burning the oil to clear it from the water faster which is what might be done will release more pollutants and GHGs into the atmosphere. Oil spills, volcanoes, earthquakes, tornadoes, forest fires - all man-made and natural disasters are no more localized events of catastrophe. Harm to a part is harm to the whole.
BP PLC the company responsible for the spill has stated that it will "take help from anyone". What happens to the people who depend on the Gulf for their livelihood, the ecosystem and the fishing industry is anybody's guess...
