What do you think happens to the trees and plants on top of the bauxite ore?
Photos of soda ash and pitch
All those rocks gotta go somewhere! Also, all the topsoil, trees and plants are stripped from the land.

A Bauxite refinery in India own by a British corporation. Locals are protesting against further mining in their hills, and several hundred villagers have already lost their homes, several have reported sores developing on their bodies after washing in rivers near the refinery, cattle have died from drinking the same water. In 1990, the world’s aluminum smelters used as much electricity as the entire continent of Africa.
Such factories like the one we just saw also produce large amounts of…
