Who was Thomas Robert Malthus?
An English economist and preacher.
How did Malthus link population and food supply?
He believed that population increased faster than food supply, population increases geometrically, and food supply only increases arithmetically.
What are the possible consequences if population growth would outstrip food supply?
Tensions in society, death from famine, war and disease, a sudden fall in population, and there would be a series of collapses - the population rising rapidly again until it hits the ‘barrier’ of slowly increasing food.
Why did Malthus write the Malthusian Theory?
Deep religious belief that people had a moral duty to keep the population low and restraint from marriage and sexual relations would achieve this, rich owned most of the resources and were comfortable, poor had very little access to resources, and finally it was wrong to give assistance to the poor because they were less able to understand the risks and therefore limit population growth.
