Coal Pollution, Emissions, Climate Change: Coal is abundant and inexpensive. Assuming that current rates of usage and production do not change, estimates of reserves indicate that enough coal remains to last more than 200 years. There are, however, a variety of problems associated with the use of coal. Mining operations are hazardous. Each year hundreds of coal miners lose their lives or are ...
