Strip Mining: A Destructive Way of Coal Extraction

This is because by definition the process of strip mining involves striping away trees, plants and topsoil so that the coal can be accessed underneath. This means that surface mining destroys mountain tops, landscapes, forests and wildlife habitats. On top of that, it leads to soil erosion and destruction of agricultural land.
