oal is energy stored in dead plant matter from prehistoric times. Large
mines built to extract coal erode the soil, leach toxic chemicals into
nearby streams and aquifers, and destroy essential habitats. Burning coal
generates 55% of the electricity in the U.S., while it produces about
2/3rds of the sulfur dioxide, 1/4th of the nitrogen oxide, and 1/3rd of
the carbon dioxide emissions in our air. Concerns about the effects of
this pollution on global climate and the acid damage it causes to the
environment is leading to seriously restricting its use.
