How can humans reduce the amount of endangered and extinct species?

A.Minimize
B.Introduce new predators to an environment
C.Pollute other environments
D.Hunt more animals for food

A)

Explanation:

The question seems to be incomplete but the answer should still be A) regardless of what it says:

Option choice B) Introduce new predators to an environment would not help reduce the amount of endangered and extinct species. Invasive species are harmful for native species and can increase the amount of endangered/extinct species because the native species may not be able to compete.

Option choice C) Pollute other environments would not help reduce the amount of endangered and extinct species. Polluting environments is harmful to native species and can increase the amount of endangered/extinct species.

Option choice D) Hunt more animals for food would not help reduce the amount of endangered and extinct species. Over hunting reduces the population of a species and damages the ecosystem, which could increase the amount of endangered/ extinct species.

Therefore using process of elimination, option choice A) should be the correct one.
