More evidence has emerged indicating the size of the oil spill is far larger than BP and the government has publicly acknowledged. Marine scientists say they have found enormous plumes of oil in the Gulf of Mexico. The New York Times reports one of the oil plumes is ten miles long, three miles wide, and 300 feet thick in spots. Scientists worry the plumes could cause oxygen levels in the Gulf to eventually fall so low as to kill off much of the sea life near the plumes.
