Over-population is one of the strongest factors responsible for a nation’s poverty and unemployment. It disturbs the earth’s principal biological systems leading to degradation of environment. The author highlights the problem of over-population by pointing out the mental set-up of the poor who feel more children means more workers to earn money. They do not realize that more children only mean more unemployed people. He argues that development is the best contraceptive, which includes spread of education, improvement of health and rise in income.
Spread of education leads to awareness among people, which in turn results in a fall in the ‘fertility’ rate. The author makes a comment which emphasizes the never ending circle of population and poverty by asserting that “The choice is really between control of population and the perpetuation of poverty.”
