As we mark the fifth anniversary of the explosion that rocked the Deepwater Horizon rig, claiming 11 lives and sparking a 87 day-long, 200-million-gallon oil spill in the Gulf of Mexico, studies continue to reveal the devastating impact of the oil—and dispersants used in clean up—on marine life. Recent reports show that the dispersants were more damaging to corals than the oil itself, and continue to diminish shellfish and sea turtle populations, while large questions loom over the ongoing unexplained deaths of dolphins along the Gulf Coast.
