What is Biodiversity?

This excerpt from the KET Kentucky Life Biodiversity series, offers a brief overview of what we mean when we refer to the biodiversity of a particular area or region.

Environmental Impact of Acid Mine Drainage

This video shows how acid mine drainage from an abandoned coal mine has affected Wildcat Branch in Kentucky's Daniel Boone National Forest. Because the creek has a very acidic pH of 2.9, most organisms cannot survive there, and Wildcat Branch is essentially dead.
