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.
