What Is the Environmental Impact of Mining and Burning Coal?

Coal starts as peat, or sections of partially decomposed organic matter that accumulate on the earth's surface. Over millions of years, the peat is buried and heat and pressure transform it into increasingly pure forms of coal called lignite, sub-bituminous, bituminous, and anthracite coal.. These fossil fuels are limited or nonrenewable resources; after they serve their fuel purpose, they
