Answer:
Surface and underground mining both have the potential to pollute water.
Surface mining devastates terrestrial ecosystems more than subterranean mining
Explanation:
- Surface mining (also known as open-cast mining) wreaks havoc on ecosystems by removing the top layers of soil in order to gain access to minerals that are on or near the surface.
- The vegetation, microbes, and their habitats are all destroyed as a result of this. This also exposes the bare surface to precipitation runoff, which can carry dangerous compounds into water bodies and pollute them.
- While subterranean mining may not have as severe an impact on the ecosystem, it does risk polluting underground aquifers.
The surface mining have a greater impact on land ecosystems than underground mining?
Large amounts of land are cleared of plants and soils during surface mining.
Acid and heavy metals can enter local water from both methods of mining.
