"Using satellite images, researchers tracked the scars spreading across Appalachia. They found 3 times more land being stripped per ton of coal than in the 1980s."
"Strip mining across the mountaintops of Appalachia is scarring as much as three times more land to get a ton of coal than just three decades ago, new research shows.
The data and a series of new maps that track the spread of surface mining across the region suggest that even as the industry has declined, what continues likely has an oversized impact on people and the environment.
If mining companies have to do more blasting and digging for the same amount of coal, that means more dust in the air and more pollution in streams, said Appalachian Voices Programs Director Matt Wasson, who worked on the study with researchers from Duke University, West Virginia University, Google and SkyTruth."
