Thomas Malthus: Theory of population
Malthus stated that, the populations’, of the world would increase in geometric proportions while the food resources available for them would increase only in arithmetic proportions. In simple words, if human population was allowed to increase in an uncontrolled way, then the number of people would increase at a faster rate than the food supply. A point would come when human populations of the world reach the limit up to which food sources could support it. Any further increase would lead to population crash caused by natural phenomena like famine or disease. According to him, human society could never be perfected. He believed that man is a lazy animal, who would lead a satisfied life and procreate as long as his family was well fed. However, as soon as human population would feel constraints in food supply due to increase in population, he would again work hard to provide enough for his family. This might lead to an increase in agricultural production to provide for all , but at the same time man would be back to his complacent stage , where all his needs would be fulfilled .this would start the cycle of overpopulation and food shortage , all over again .having been a clergy ,Malthus validated his theory on moral grounds that suffering was a way of making human beings realize the virtues of hard work and moral behavior .such kind of suffering due to overpopulation and limited food supply was inevitable. Malthus theory was based on the assumption that the power of population to multiply is much greater than the power of the earth to provide subsistence for man .in his own words passion between the sexes is an inevitable phenomenon , hence , when unchecked, population would grow at such a high rate that it would outstrip food supply. According to him, disease, food shortage and death due to starvation, were nature’s way to control population. He proposed that human being adopt measure
