Thomas Robert Malthus (1766-1834) was an English economist and demographer who is best known for his work on population theory. Malthus’s theory states that population growth is always geometric, while the food supply can only grow arithmetically. This means that population will eventually outstrip the food supply, leading to famine and disease.
Malthus’s theory was controversial when it was first published, and it remains so today. Some people believe that Malthus was wrong, and that population growth can be controlled through economic development and technological innovation. Others believe that Malthus was right, and that we are facing a serious problem of overpopulation.
