In 2010 4.9 million barrels (210 million US gal; 780,000 m3) of oil was dumped into the Gulf of Mexico when BP's Deepwater Horizon oil rig exploded. The effects of the BP oil spill will continue to be felt by future generations, as contamination has been found throughout the entire food chain.[15] More than 8,000 marine birds, sea turtles and marine mammals were found dead or injured within months of the clean up effort.
