Biodiversity at Risk  Earth has experienced several mass extinctions, each probably caused by a global change in climate.  It takes millions of years.

Overpopulation occurs when a population of a species exceeds the carrying capacity of its ecological niche. It is a function of the number of individuals.

Extinction… is a natural process by which some branches (lineages) of the tree of life are pruned away.
