The Malthusian Theory of Population is a theory of exponential population growth and arithmetic food supply growth. Thomas Robert Malthus, an English cleric, and scholar published this theory in his 1798 writings, An Essay on the Principle of Population. ... These checks would lead to the Malthusian catastrophe.
So Malthus may yet prove to be correct. Population to be controlled only via starvation. Well, who'd have thought it!!!
