Suggest that war, natural disasters, disease, and famine hold the world's population in check, ensuring that humans do not outstrip their food supply.

Thomas Malthus

Explanation:

Malthus suggested that the population growth is potentially exponential and the growth of the food supplies is linear and he asserted that these checks like the wars, famines and the diseases try to keep the growth of population in line with that of the food supply. As it would return the population to more sustainable and lower levels. As food resources would be pressurized by the large growth of population and thus ensuring that humans don't outstrip the supply and are regarded as necessary checks.
