YOu hear about the environmental cost of using coal, but it is very upsetting to read about specific people and how their lives have changed, for the worse, because of coal mining.  Further upsetting is to hear about the animals effected.  Elephants invading villages, being electrocuted, hurting humans, all because their land is being taken for coal.  Sad! People are dying from lack of fresh air and water, and it is wrong.
