<P> Malthusianism is the idea that population growth is potentially exponential while the growth of the food supply is arithmetical at best . It derives from the political / economic thought of the Reverend Thomas Robert Malthus , as laid out in his 1798 writings , An Essay on the Principle of Population , Malthus believed there were two types of `` checks '' that in all times and places kept population growth in line with the growth of the food supply : `` preventive checks '' , such as moral restraints ( abstinence , delayed marriage until finances become balanced ) , and restricting marriage against persons suffering poverty or perceived as defective , and `` positive checks '' , which lead to premature death : disease , starvation , war , resulting in what is called a Malthusian catastrophe . The catastrophe would return population to a lower , more `` sustainable '' , level . Malthusianism has been linked to a variety of political and social movements , but almost always refers to advocates of population control . </P>
