The enormous scale which these projects are run on completely overwhelms the environment in which they take place. The practice of clear-cutting when done by loggers is strictly regulated, prompt replanted is enforced, and the result is a renewal of the decimated forest land. This is not the case with MRM, however; few sites are replants and even then far from successfully. MRM succeeds in turning a beautiful mountain forests, home to fragile ecosystem and major tourist attraction, into a waste of dirt.
Another element to all this is the people who live near these mining sites. As the mining projects move into an area, the coal company will buy up all the existing houses and demolish them. Traditionally coal miners themselves, these people often lose not only their homes to MRM, but also their jobs. Because of the increased use of massive machines, the actual number of mining jobs have gone down; a small group of workers can clear an entire mountaintop. The coal companies are brutally oblivious to the residents near their mining projects who are exposed to extreme pollution and very undesirable living conditions due to their irresponsible industry practices.
