May 27, 2020 Mining remains an essential and growing part of the modern industry. By some estimates, it makes up nearly 45% of the total global economy, and mineral production continues to increase as demand for raw materials grows around the world.. However, many mining techniques still in use can have serious impacts on both the mining site itself and the surrounding environment.

Environmental Risks of Mining

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.
