Surface mining is more ecologically damaging than subsurface mining.

Please select the best answer from the choices provided:

A. True
B. False

Answer :

Final answer:

Surface mining, notably through mountaintop mining, causes more ecological damage than subsurface mining due to habitat destruction and significant biodiversity loss. While subsurface mining impacts the landscape less directly, both methods can lead to soil and water contamination. Overall, surface mining's extensive alterations to land make it more detrimental to ecology.


Explanation:

Is Surface Mining More Ecologically Damaging Than Subsurface Mining?

Surface mining, particularly through practices like mountaintop mining (MTM), is generally regarded as more ecologically damaging than subsurface mining. Surface mining involves the removal of large areas of soil and rock to access coal and other minerals, which leads to significant destruction of local habitats. The practice of MTM specifically removes entire mountain tops and disposes of the debris in adjacent valleys, causing extensive habitat loss and impacting local biodiversity.

In contrast, subsurface mining, while it can have environmental impacts, does not typically disturb as much surface land. Although it poses risks such as potential methane gas release, surface subsidence, and water pollution from leached materials, it usually leaves the surface landscape intact compared to surface mining.

Environmental Impacts

  1. Habitat Destruction: Surface mining removes the habitat directly by flattening landscapes.
  2. Biodiversity Loss: Habitats destroyed by surface mining do not support life, leading to species extinction.
  3. Water Quality Issues: Both mining types can lead to water pollution, but surface mining often creates more immediate and widespread contamination.

In summary, while both mining methods have ecological consequences, surface mining tends to have more profound and visible ecological damage due to its extensive land alteration.
