Dark clouds of smoke and fire emerge as oil burns during a controlled fire of the Deepwater Horizon gulf oil spill in the Gulf of Mexico in this May 6, 2010 handout file photo. When BP's Deepwater Horizon oil rig exploded and sank in the Gulf of Mexico last April, killing 11 workers, authorities first reported that no crude was leaking into the ocean. They were wrong. One year on, oil from the largest spill in U.S. history clogs wetlands, pollutes the ocean and endangers wildlife, not to mention the toll it has inflicted on the coastal economies of Florida, Mississippi, Alabama and especially Louisiana.
