Thomas Robert Malthus(B. 1766 D. 1834) was a British scholar. In the year 1798, he published his much famous theory about population growth. Even great Charles Darwin, as per his own noting, had found it amusing. In his theory, Malthus had stated that for any country, the population would always grow in a Geometrical Ratio. Whereas, the production of food, to sustain this population, would grow in an Arithmetical ratio. In simple words, this means that the rate of growth of population is much higher than the rate of growth of production of food to sustain this population. However, the nature would create automatically, calamities like, floods, famines, pandemics and wars, to keep the population in check and in line with food production. If humans interfere with this natural law, there would be uncontrolled growth of population.
