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.
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 ...
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.
Researchers from Oxford Population Health used data from nearly 500,000 participants in the U.K. to assess the influence of 164 environmental factors and genetic risk scores for 22 age-related ...
In 2007, Jeffrey Sachs gave a number of lectures (2007 Reith Lectures) about population planning and overpopulation. In his lectures, called "Bursting at the Seams", he featured an integrated approach that would deal with a number of problems associated with overpopulation and poverty reduction. For example, when criticized for advocating ...
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 ...
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).
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 ]
