Numbers show that the prediction of Thomas Malthus should be treated with more respect. Even without saying it, he inspired the worldwide initiative for scientific studies and search for discoveries to improve crop farming methods.
In the 18th century, he published his famous treatise Essay on the Principles of Population. This paper survived and has become the basis of the Malthusian Theory.
An English clergyman, economist and demographer, Thomas Malthus had come to the conclusion that the rate of growth of the world’s population was outstripping the capacity of the land to provide the food necessary to subsistence and that only recurring famine, pestilence, or wars would tend to keep down the number of inhabitants (Rook, A. (ed.). 1958. The Origins and Growth of Biology. Harmondsworth, Middlesex: Penguin Books, Ltd. p. 268).
