The new Malthusians worry that ''exponential growth'' of the population will lead to a scarcity of food.
Malthusianism is the belief that population growth might be exponential while other resource growth, such as that of the food supply, is linear. This would eventually result in a decline in living conditions that would lead to a mass extinction of the population. Known as a Malthusian disaster.
Neo-Malthusianism promotes population control in order to protect the environment and provide resources for present and future human populations as well as other species. Organizations like the Malthusian League and others use the term "Malthusian" in Britain to describe arguments in favor of preventive birth control.
