The Environmental Impact of Mining (Different Mining Methods Compared)

Soil Erosion, Pit mining, one of the most common techniques, hollows out land to extract raw materials. It blasts away land and strips vegetation, leaving the area vulnerable to soil erosion — the wearing away of the topsoil layer of time. Topsoil is necessary for plants to grow, and without it, mining sites can't truly recover.
