Media commentary interpreted this as suggesting overconsumption represents a greater environmental threat as an overpopulation scenario may never occur. [68] [233] Some human population planning strategies advocated by proponents of overpopulation are controversial for ethical reasons.
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 ...
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 ...
Behavioral sink" is a term invented by ethologist John B. Calhoun to describe a collapse in behavior that can result from overpopulation. The term and concept derive from a series of over-population experiments Calhoun conducted on Norway rats between 1958 and 1962. [ 1 ]
Rosling states that this number is representative worldwide, the reason why the total number of children globally is now at a stable level of 2 billions. According to him, the so-called population explosion has already been overcome. The human population will peak at eleven billions, and stabilize at this level by the end of the century. [1] [2]

The root problem in all but one of Diamond's factors leading to collapse is overpopulation relative to the practicable (as opposed to the ideal theoretical) carrying capacity of the environment. One environmental problem not related to overpopulation is the harmful effect of accidental or intentional introduction of non-native species to a region.
Population Control: Real Costs, Illusory Benefits is a nonfiction book by Steven W. Mosher, president of the Population Research Institute, first published in 2008. Population Control is a detailed exposition on the global effort to combat overpopulation , arguing that not only population control is immoral in many cases, but that ...
