Mountaintop removal is a form of surface mining used primarily for extracting coal. This process involves blasting the tops off mountains to access the coal seams beneath. The removed rock and soil, known as overburden, is often dumped into nearby valleys, which can lead to environmental degradation. This mining technique can significantly alter landscapes and ecosystems. It can destroy habitats, contaminate water sources, and contribute to soil erosion. While it provides a source of energy, the long-term environmental impacts raise concerns among environmentalists and local communities.
