Answer:

Overhunting

Explanation:

  • if any environmental or human activity leads to a drastic decline in the population of individuals then such an event is known as a population bottleneck.
  • In the case of bison, overhunting (human activity) led to a bottleneck event.
  • Overhunting decreased the population of bison to such an extent that it faced the threat of extinction, however, due to regulations its population has recovered.
  • However, since the new population recovers from a small group of individuals left due to the bottleneck effect, the genetic variability is greatly reduced.

explain how the size of the of the global human population can increase while the rate of growth decreases
Makovka662 [10]
Since the rate of growth is still positive, there are still people being born and added to the population which is why the global human population is increasing. The speed at which it is increasing decreases though, but the population is still technically growing.
