What Is the Environmental Impact of Mining and Burning

Burning coal emits large amounts of carbon dioxide into the atmosphere Coal is composed almost entirely of carbon so burning coal unleashes large amounts of carbon dioxide (CO 2) into the atmosphere These emissions have been shown to increase the greenhouse effect in the atmosphere and lead to global warming Subsurface coal mining is dangerous Get price Get Price
