Question

Humans extract metals and minerals from the Earth by mining. Clearing large areas for mining can cause plants and animals to lose their habitat. The mining process also creates a huge amount of waste, which can negatively impact a region's biodiversity.

Which option best reduces the impact of mining waste on the biodiversity of a nearby ecosystem?
A.
disposing of mining waste by pumping it under the surrounding land
B.
gathering water that has been contaminated and moving it away to be treated
C.
treating mining waste at the mining site before it is released into the environment
D.
disposing of mining waste by pouring it into local rivers

Answer 1

The most effective way to mitigate the effects of mining waste on biodiversity is by treating the waste at the mining site before it is released into the environment.

Step-by-step explanation:

The best option to reduce the impact of mining waste on the biodiversity of a nearby ecosystem is C. treating mining waste at the mining site before it is released into the environment. This process helps to minimize the dispersion of pollutants and can prevent significant harm to local ecosystems. Treating the waste on-site ensures that harmful by-products are dealt with prior to being exposed to the environment, thereby reducing the potential for contamination of soil, water and ultimately protecting local biodiversity.
