Homework Answer on Energy
Mountain top removal is a method of coal mining that includes removal of the surface of a hill, summit or mountain to access covered coal seams(Juliano).Its benefits are: it is cheaper for coal companies to use this method compared to other methods, reduces energy crises as it is a reliable source of energy and it is more efficient because it is safer and saves on time in comparison with traditional coal mining methods. On the other hand, the drawbacks are that it is an environmental hazard as it destroys the natural terrain, causes air pollution, and destroys land and sea animals’ habitats. The explosives used in mountaintop removal expose human beings to health hazards.
