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 ...
This is a list of organisations who promote a moderation of the size of the human population. This is a dynamic list and may never be able to satisfy particular standards for completeness. You can help by adding missing items with reliable sources .
Some economists, such as Thomas Sowell [34] and Walter E. Williams, [35] have argued that poverty and famine are caused by bad government and bad economic policies, not by overpopulation. In his book The Ultimate Resource , economist Julian Simon argued that higher population density leads to more specialization and technological innovation ...
Human overpopulation (or human population overshoot) is the idea that human populations may become too large to be sustained by their environment or resources in the long term.
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.
Thomas Robert Malthus, after whom Malthusianism is named. Malthusianism is a theory that population growth is potentially exponential, according to the Malthusian growth model, while the growth of the food supply or other resources is linear, which eventually reduces living standards to the point of triggering a population decline.

NPG works on overpopulation issues and advocates for a gradual reduction in U.S. and world population. The organization believes the optimal population for the United States is between 150 and 200 million, while the optimal world population is estimated to be two to three billion.
