Effects of Gold Mining on the Environment | Sciencing
Most forms of gold mining involve moving massive amounts of soil and rock, which can be detrimental to the surrounding wildlife habitat. The U.S. Environmental Protection Agency estimates that the development of a proposed gold and copper mine in Alaska's Bristol Bay would destroy at least 24 miles of streams that support the world's largest sockeye salmon fishery.
