Malthus expressed a pessimistic view over the dangers of over population and claimed that food supply was the main limit to population growth. He believed that the human population increases exponentially (2, 4, 8, 16, 32 etc), whereas food supplies can only grow arithmetically (2, 4, 6, 8 etc). Malthus said that there are therefore ‘checks’ on the population. He identified two different types of checks on the population which would limit further population growth. These are; preventative or negative checks and positive checks. With these checks he saw them as a natural way of keeping the population at a sustainable level. As if the population went over the crisis point there would be misery; were positive checks on mortality would kick in. As if a government wanted to stop or reduce population growth it would use moral restraint were negative checks on fertility would be enforced.

In 1965 Ester Boserup, a Danish economist asserted that an increase in population would stimulate technologists to increase food production. As boserup said any rise in population would increase demand for food and this would act as an incentive to change agrarian technology and produce more food. Her theory can be summed up by the sentence ‘necessity is the mother of invention’. Therefore population growth will spark innovators who will sovle the problem s the increasing population has caused therefore making it sustainable for a growing population.
