Overpopulation or a chronic victim is a statistical state whereby the number of an organism exceeds the resistance of its habitat. In ordinary parlance, the term usually refers to the relationship between the number of people and the environment, the Earth. [1]
Population overload depends not only on population size or density, but on the proportion of the population with the resources that can be maintained, on resource use measures and the distribution due to the number of people. That used. If for an environment of 10 people, but only enough water and food for 9, then in a closed system where there is no commercial relationship, that environment is overpopulated; if the population is 100 but there is enough food, shelter and water for 200 people for an unlimited future, then it is not an overpopulation. Population overcrowding can result from increased fertility, a decline in mortality due to health development, an increase in immigration, or an unmanageable biome and depletion. resources. Very sparsely populated areas may also meet chronic victims, where they may or may not be capable of sustaining human life (for example, the central Sahara or Antarctic regions). .
Resources considered when evaluating whether an ecosystem is overpopulated include clean water, air, food, shelter, warmth, and other resources needed to maintain it. life. If the quality of human life is considered, other resources such as health care, education, appropriate waste water and waste treatment can be considered. Overpopulation places put pressure on life-sustaining resources, leading to a decline in quality of life. [2]
Steve Jones, head of the department of biology at the University of London, said, "Humans are 10,000 times more numerous than they should be, according to the laws of the animal kingdom, and fortunately we are Without agriculture. Without agriculture, the world's population is probably less than half a million now. " [3]
Some countries have sought to increase their resilience using techniques such as modern agriculture, desalination, and nuclear.
