The True Cost of Coal - Ground Truth Trekking

Most coal mining in the U.S. is surface mining, which includes strip mining and mountaintop removal. In surface mines, the original ecosystem at the mine site is destroyed in the process of removing the coal. Coal companies are required to plant vegetation to reclaim the site after mining, restoring the original ecosystem may be difficult, particularly in wetlands areas.
