The Trump administration has told the National Academy of Sciences to stop working on a study about the potential health risks for people living near mountaintop coal-removing sites in Central Appalachia.

“Everyone knows there are major health risks living near mountaintop removal coal mining sites,” Bill Price, the senior Appalachia organizer at the Sierra Club, said in a statement. “It’s infuriating that Trump would halt this study on the health effects of mountaintop removal coal mining, research that people in Appalachia have been demanding for years.”
