Battle raging in US mining country

For years, a battle has been raging in the Appalachian Mountains over a coal-mining practice known as "mountaintop removal mining". In the last three decades this kind of mining has flattened some 2,500 square miles, and buried more than 1,200 miles of mountain streams. With a new administration in Washington, the battle over mountaintop removal mining is heating up, most notably in southern West Virginia - and grassroots activists are at the forefront.
