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.

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.
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.
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.

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).
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.
Environment destruction caused by humans is a global, ongoing problem. [4] Water pollution also cause problems to marine life. [5] Some scholars believe that the projected peak global population of roughly 9-10 billion people could live sustainably within the earth's ecosystems if humans worked to live sustainably within planetary boundaries.
