The Trump Administration is proposing to ease regulations that were adopted to make offshore oil and gas drilling operations safer after the 2010 Deepwater Horizon disaster. This event was the worst oil spill in U.S. history. Eleven workers died in the explosion and sinking of the oil rig, and more than 4 million barrels of oil were released into the Gulf of Mexico. Scientists have estimated that the spill caused more than US$17 billion in damages to natural resources.
