The author believes that the world’s population growth is one of the most powerful factors distorting future human society because a growing population not only increases food demand but also depletes current resources at an unrecoverable rate. Fertility rates are declining as incomes rise, education spreads, and health improves. As a result, development is the most effective contraceptive. However, if the current rate of population growth continues, development may be impossible. The rich get richer, while the poor have children who keep them poor. Having more children does not imply more workers, but rather more unemployed people. It is not advocated that humans be treated like cattle and forced to be sterilized. However, there is no alternative to voluntary family planning that does not involve some form of coercion. The choice is really between population control and poverty perpetuation.
