Mining Methods. Some resources can be mined using more than one method, as in the case of coal, gold and uranium, and can then have many environmental impacts which include deforestation, destruction of habitats, soil erosion, disruption of watershed, and pollution.
Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat.
