Overpopulation is an undesirable condition where the number of the existing human population exceeds the carrying capacity of earth. Every nook and corner of India is a clear display of the increasing population. According to the Indian census, carried out in 2011, the population of India was exactly 1,210,193,422, which means India has crossed the 1-billion mark. Thomas Robert Malthus, an English cleric and scholar, published this theory in his 1798 writings, An Essay on the Principle of Population. According to his theory, human populations grow exponentially whereas the food production grows at an arithmetic rate.
