Mountain Top Removal Coal Mining

Coal, essentially super compressed plant matter, exists in one form or another around much of the world and has historically served as a fuel for many purposes. Coal in the ground is part of the larger water system of the planet, acting as a filter as water percolates down to the aquifer below. When the soil, trees, and other flora are stripped off, rainwater, instead of soaking into the living soil, reacts with the exposed coal producing acid mine drainage.
