We hear that Third World poverty is due to overpopulation, too many people having too many children to feed. Actually, over the last several centuries, many Third World lands have been less densely populated than certain parts of Europe. India has fewer people per acre-but more poverty-than Holland, Wales, England, Japan, Italy, and a few other industrial countries.
Furthermore, it is the industrialized nations of the First World, not the poor ones of the Third, that devour some 80% of the world's resources and pose the greatest threat to the planet's ecology.
This is not to deny that overpopulation is a real problem for the planet's ecosphere. Limiting population growth in all nations would help the global environment but it would not solve the problems of the poor-because overpopulation in itself is not the cause of poverty but one of its effects. The poor tend to have large families because children are a source of family labor and income and a support during old age.
Frances Moore Lappe and Rachel Schurman found that of seventy Third World countries, there were six-China, Sri Lanka, Colombia, Chile, Burma, and Cuba-and the state of Kerala in India that had managed to lower their birth rates by one third. They enjoyed neither dramatic industrial expansion nor high per capita incomes nor extensive family planning programs. The factors they had in common were public education and health care, a reduction of economic inequality, improvements in women's rights, food subsidies, and in some cases land reform. In other words, fertility rates were lowered not by capitalist investments and economic growth as such but by socio-economic betterment, even of a modest scale, accompanied by the emergence of women's rights.
