Safeopedia explains Population Crash
The causes of a population crash are somewhat varied, but include scarcity of environmental resources that are needed for survival, growth and reproduction, predation, and waste accumulation. It can also be caused by an initially overpopulated group and competition between members of the same species. A population crash often follows a peak and can lead to eventual extinction, as an environment is unable to support a species any longer.
