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. The topic is usually discussed in the context of world population , though it may concern individual nations, regions, and cities.
The term and concept derive from a series of over-population experiments Calhoun conducted on Norway rats between 1958 and 1962. [1] In the experiments, Calhoun and his researchers created a series of "rat utopias" [ 2 ] – enclosed spaces where rats were given unlimited access to food and water, enabling unfettered population growth.
Malthus overpopulation would lead to war, famine, and diseases and in the future, society won't be able to feed every person and eventually die. Malthus theory was incorrect, however, because by the early 1900s and mid 1900s, the rise of conventional foods brought a decline to food production and efficiency increased exponentially.
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.
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 is a myth.

[15] With the onset of the Thirty Years' War (1618–48), characterized by widespread devastation and deaths brought on by hunger and disease in Europe, concerns about depopulation ...
The goal of Malthusian theory is to explain how population and food production expand, with the latter experiencing arithmetic growth and the former experiencing exponential growth. [28] The controversy, however, concerns the relevance of Malthusian theory in the present world. This hypothesis is inapplicable in a number of ways.
