How does coal mining affect the environment?
As previously mentioned, coal mining and processing is responsible for contributing a significant amount of pollution to the environment. In addition, extraction techniques, such as mountaintop removal, change the surrounding landscape. In this extraction process, seams of coal are removed from the mountainside by using explosives to remove the top of the mountain, making the coal below easier to access. The excess land and debris, that was once the top of the mountain, is generally pushed into the valley below, a practice known as valley fill. This permanently alters the topography of the land, leading to obstructed waterways and increased flooding.

What are the chemicals in the air?
These chemicals include: mercury, arsenic, lead, selenium, zinc, nickel, and radium (to name a few). Burning coal for electricity creates a number of greenhouse gases, which are released into the atmosphere. Of these greenhouse gases, nitrogen oxide and sulfur dioxide react with other chemicals in the air, creating fine particles that are transported across long distances. This long-distance movement impedes other communities from maintaining clean air. In addition, the wet cooling towers of coal powered electric plants emit drift, which is made up of tiny particulate matter that humans can breathe into their lungs. Some researchers believe that in China, for example, air pollution caused by burning coal for electricity is responsible for shortening the average lifespan by 5.5 years.
