The rapid growth of population was mainly attributed to the availability of food in abundance. People ate well, became productive and started multiplying at fast rate. However, the amount of food does not increase simultaneously with the number of people.
Malthus theorem argues that while population grows geometrically from 2 to 4 to 8 and so on, the supply of food increases arithmetically from 1 to 2 to 3 and so on; implying that population grows at a faster rate than increase in food supply. Malthus, an economist, then suggested that without checking births, country’s population or the world will run out of food supply (Henslin, 2009). This is indeed correct. With a rapid growth of population, space is likely to be occupied by residential houses. Places that could be used for farming will be turned into peoples’ home to house the growing population. This implies that less food will be available and therefore insufficient to sustain the population. Malthus theorem can therefore be regarded as true.
