The Malthusian theory was concerned about the relationship between population growth rate and natural resources. The theory, proposed by Thomas Malthus, stated that population grows at a geometric rate (i.e. faster) while food production grows at an arithmetic rate (i.e. slower). This means that eventually, the population would outstrip the food supply and lead to famine, war, and other problems. Malthus believed that population control was necessary to avoid such problems, and he recommended practices such as late marriage and birth control to limit population growth.
