Strip Mining Huge bulldozers and other machines are used to clear away large strips of the Earth’s surface. http://media.treehugger.com/assets/images/2011/10/strip-mine.jpg

Effects of Mining Disruption of the land’s surface. Waste materials left behind. Land erosion. Landslides. Pollution. Uses large amounts of energy.

How to reduce destructive effects Reclamation: A restoration of the land to its previous condition. Re-using or recycling. Reduction of the use of mined minerals. Stiff fines or fees.
