![]() ![]() Typically, an overpopulation causes the entire population of the species in question to become weaker, as no single individual is able to find enough food or shelter. In ecology, overpopulation is a concept used primarily in wildlife management. Societies may be judged overpopulated when their human numbers cause impacts that degrade ecosystem services, decrease human health and well-being, or crowd other species out of existence. Animals often are judged overpopulated when their numbers cause impacts that people find dangerous, damaging, expensive, or otherwise harmful. Judgements regarding overpopulation always involve both facts and values. The animals in an overpopulated area may then be forced to migrate to areas not typically inhabited, or die off without access to necessary resources. This may be caused by increased birth rates, lowered mortality rates, reduced predation or large scale migration, leading to an overabundant species and other animals in the ecosystem competing for food, space, and resources. Overpopulation or overabundance is a phenomenon in which a species' population becomes larger than the carrying capacity of its environment.
