THIS GUY DOESN'T EVEN KNOW WHAT HE IS TALKING ABOUT!!!!!!!!

This is a couple of paragraphs from an essay i wrote on coal power:

An average of 170 pounds of mercury is made by one coal plant every year. When 1/70 of a teaspoon of mercury is put in to a 50-acre lake it can make the fish unsafe to eat. Coal power puts the lives of the people who dig the coal in danger, and it gives them poor lung quality. Also, it ruins the natural habitats of animals.

A coal plant generates about 3,700,000 tons of carbon dioxide every year; this is one of the main causes of global warming. A single coal plant creates 10,000 tons of sulfur dioxide, which causes acid rain that damages forests, lakes, and buildings. When people dig for coal, they cut down many trees. A coal plant also creates 720 tons of carbon monoxide; which causes headaches and place additional stress on people with heart disease. (http://www.ucsusa.org/clean_energy/coalvswind/c02c.html)

A 500-megawatt coal- fired plant draws about 2.2 billion gallons of water from near by bodies of water. This is enough water to support approximately 250,000 people. Some people have said that coal power is good, because coal power is reliable and affordable. It may be reliable and affordable, but in the future the damage that coal power would cause, would be much more expressive. (http://www.ucsusa.org/clean_energy/coalvswind/c02b.html)
