Scholar Heather Alberro rejects the overpopulation argument, stating that the human population growth is rapidly slowing down, the underlying problem is not the number of people, but how resources are distributed and that the idea of overpopulation could fuel a racist backlash against the population of poor countries.

The Global Footprint Network purports to be able to measure how much the human economy demands against what the Earth can renew. [13] [14] The Optimum Population Trust (now called Population Matters) has listed what they believe is the overshoot (overpopulation) of a number of countries, based on the above. [15]
Logan's Run (Book) - State-mandated euthanasia at 21 for all people (30 in the film) to conserve resources. Make Room! Make Room! (Book) - Novel, explores the consequence of overpopulation. Ishmael (Quinn novel) - Explores the biological and ecological causes of overpopulation which is a result of increased carrying capacity for humans.
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.
This increased level of poverty eventually causes depopulation by decreasing birth rates. If asset prices keep increasing, social unrest would occur, which would likely cause a major war, revolution, or a famine. Societal collapse is an extreme but possible outcome from this process. The theory posits that such a catastrophe would force the ...
Research shows that people who eat the most fiber cut their risk of dying from any cause by 23% compared to those who eat the least fiber. And fiber is especially important for heart health.
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.
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).
