Answer 2

The answer to this question is option d: Developing a vegetation cover.

• Ecological equilibrium refers to a state of equilibrium between all living and non-living organisms in the environment.
• Mining sites are constantly subjected to mining activities, and as a result, the natural balance of the area is disrupted.
• The development of a plant cover in such an area will aid in the recovery or restoration of the soil.
• Option a is incorrect in this case because the land is not intended for farming.
• Option b is similarly unsuitable because there is no grazing in this location.
• It is possible to avoid soil erosion, but this does not guarantee that the soil will be totally restored.
• For the time being, vegetation cover and regular revegetation work will rebalance the ecology of the mined region.
• Hence d option is correct.
