Explanation:

Thomas Robert Malthus, an English cleric and scholar, published this theory in his 1798 writings, An Essay on the Principle of Population. Malthus believed that through preventative checks and positive checks, the population would be controlled to balance the food supply with the population level

The increase in numbers is necessarily limited by the means of subsistence Population invariably increases when the means of subsistence increase, unless prevented by powerful and obvious checks." Malthus based his reasoning on the biological fact that every living organism tends to multiply to an unimaginable extent.

The Malthusian Theory of Population is a theory of exponential population growth and arithmetic food supply growth ... He believed that through preventative checks and positive checks, the population would be controlled to balance the food supply with the population level.
