Question

What happens to the environment as a result of decreased biodiversity?

O Pollution increases.
O The earth becomes more exposed to asteroid impact.
O Species can no longer migrate to faraway islands.
O Ecosystems become less stable.

Answer 1

Pollution increases

Step-by-step explanation:

Pollution is a major threat to biodiversity, and one of the most difficult problems to overcome; Pollutants do not recognize international boundaries. For example, agricultural run-off, which contains a variety of fertilizers and pesticides, may seep into ground water and rivers before ending up in the ocean. Atmospheric pollutants drift with prevailing air currents and are deposited far from their original source.

Answer 2

Ecosystems become less stable

pollution leads to decreased biodiversity, but is not caused by it
