Indeed, some analysts claim that overpopulation's most serious impact is its effect on the environment. [142] Some scientists suggest that the overall human impact on the environment during the Great Acceleration , particularly due to human population size and growth, economic growth , overconsumption, pollution , and proliferation of ...
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.
The practice, traditionally referred to as population control, had historically been implemented mainly with the goal of increasing population growth, though from the 1950s to the 1980s, concerns about overpopulation and its effects on poverty, the environment and political stability led to efforts to reduce population growth rates in many ...
The effect stress has on expecting women may not only affect them, but their child as well. Studies have shown a link between child mental health and behavioral problems to maternal stress during pregnancy. Stress in the body leads to an increase in the cortisol levels. Maternal stress, therefore, exposes the foetus to high cortisol levels.
Population, health, and the environment [citation needed] (PHE) is an approach to human development that integrates family planning and health with conservation efforts to seek synergistic successes for greater conservation and human welfare outcomes than single sector approaches. There is a deep relationship between population, health and ...
Education is a major social determinant of health, with educational attainment related to improved health outcomes, due to its effect on income, employment, and living conditions. [ 56 ] [ 57 ] [ 58 ] [ 1 ] Social resources, such as education, determine life expectancy and infant mortality, which measures health. [ 59 ]
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.
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).
