Environmental groups Defenders of Wildlife, the Gulf Restoration Network, Save the Manatee Club, and the Southern Environmental Law Center filed suit against BP under the Endangered Species Act (ESA) for the ongoing harm to endangered and threatened wildlife caused by the Deepwater Horizon blowout and oil spill in the Gulf of Mexico. The groups are asking the court to order BP to mitigate the ongoing harm from the disaster to dozens of endangered or threatened animal species inhabiting the Gulf region, including sea turtles, whales, birds, and manatees.
