Indeed, some analysts claim that overpopulation's most serious impact is its effect on the environment. [142] Some scientists suggest that the overall human impact on the environment during the Great Acceleration , particularly due to human population size and growth, economic growth , overconsumption, pollution , and proliferation of ...
Overpopulation or overabundance is a state in which the population of a species is larger than the carrying capacity of its environment.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.
In environmental science, a population "overshoots" its local carrying capacity — the capacity of the biome to feed and sustain that population — when that population has not only begun to outstrip its food supply in excess of regeneration, but actually shot past that point, setting up a potentially catastrophic crash of that feeder population once its food populations have been consumed ...
The practice, traditionally referred to as population control, had historically been implemented mainly with the goal of increasing population growth, though from the 1950s to the 1980s, concerns about overpopulation and its effects on poverty, the environment and political stability led to efforts to reduce population growth rates in many ...
However, attributing overpopulation as a cause of environmental issues is controversial. Demographic projections indicate that population growth is slowing and world population will peak in the 21st century, [34] and many experts believe that global resources can meet this increased demand, suggesting a global overpopulation scenario is unlikely.
Overpopulation — Burial • Overpopulation in companion animals • Tragedy of the commons • Gender Imbalance in Developing Countries • Sub-replacement fertility levels in developed countries; Mutation breeding — Genetic pollution; Synthetic biology — Synthetic DNA • Artificially Expanded Genetic Information System • Hachimoji DNA
Population pressure, a term summarizing the stress brought about by an excessive population density and its consequences, is used both in conjunction with human overpopulation and with other animal populations that suffer from too many individuals per area (or volume in the case of aquatic organisms).
This has the side effects of ensuring a strong stock among the survivors and controlling the population. In the absence of predators, animal species are bound by the resources they can find in their environment, but this does not necessarily control overpopulation.
