Question

how does mining impact the environment?
it has a positive impact on the environment by permanently altering the ecosystem.
it has a positive impact on the environment by releasing chemicals into the environment.
it has a negative impact on the environment by allowing toxic chemicals to harm wildlife.
it has a negative impact on the environment by providing new niches for wildlife to inhabit.

Explanation:

To determine the correct answer, we analyze each option:

• Option 1: Permanently altering the ecosystem is typically negative, not positive for the environment, so this is incorrect.
• Option 2: Releasing chemicals into the environment is generally harmful, not a positive impact, so this is incorrect.
• Option 3: Mining often involves the release of toxic chemicals that can harm wildlife, which is a negative environmental impact. This makes sense.
• Option 4: Providing new niches for wildlife is not a typical negative impact of mining, and mining usually disrupts habitats rather than creating beneficial niches for wildlife. So this is incorrect.

Answer:

C. It has a negative impact on the environment by allowing toxic chemicals to harm wildlife.
