Campbell County, Tennessee, U.S. - A group of citizens associated with Katuah Earth First! and the Mountain Justice Summer campaign to halt mountain top removal have set up a roadblock on Zeb Mountain in Tennessee. At least three people have been arrested while shutting down National Coal's operation on the mountain. Coal companies in Appalachia, mine by blowing up the entire mountain tops and then bulldozing them into the valleys with massive machines. The practice causes extensive environmental damage, not only destroying mountain and valley ecosystems, but impacting entire watersheds.
