Threats to the Environment


In his concern about "a continual diminution of happiness" from population growth, Condorcet was a pioneer in considering the possibility that natural raw materials might be used up, thereby making living conditions worse. In his characteristically rationalist solution, which relied partly on voluntary and reasoned measures to reduce the birth rate, Condorcet also envisaged the development of less improvident technology: "The manufacture of articles will be achieved with less wastage in raw materials and will make better use of them."(26)

The effects of a growing population on the environment could be a good deal more serious than the food problems that have received so much attention in the literature inspired by Malthus. If the environment is damaged by population pressures this obviously affects the kind of life we lead, and the possibilities of a "diminution in happiness" can be quite considerable. In dealing with this problem, we have to distinguish once again between the long and the short run. The short-run picture tends to be dominated by the fact that the per-capita consumption of food, fuel, and other goods by people in third world countries is often relatively low; consequently the impact of population growth in these countries is not, in relative terms, so damaging to the global environment. But the problems of the local environment can, of course, be serious in many developing economies. They vary from the "neighborhood pollution" created by unregulated industries to the pressure of denser populations on rural resources such as fields and woods.(27) (The Indian authorities had to close down several factories in and around Agra, since the facade of the Taj Mahal was turning pale as a result of chemical pollution from local factories.) But it remains true that one additional American typically has a larger negative impact on the ozone layer, global warmth, and other elements of the earth's environment than dozens of Indians and Zimbabweans put together. Those who argue for the immediate need for forceful population control in the third world to preserve the global environment must first recognize this elementary fact. This does not imply, as is sometimes suggested, that as far as the global environment is concerned, population growth in the third world is nothing to worry about. The long-run impact on the global environment of population growth in the developing countries can be expected to be large. As the Indians and the Zimbabweans develop economically, they too will consume a great deal more, and they will pose, in the future, a threat to the earth's environment similar to that of people in the rich countries today. The long-run threat of population to the environment is a real one.


Women's Deprivation and Power


Since reducing the birth rate can be slow, this and other long-run problems should be addressed right now. Solutions will no doubt have to be found in the two directions to which, as it happens, Condorcet pointed: (1) developing new technology and new behavior patterns that would waste little and pollute less, and (2) fostering social and economic changes that would gradually bring down the growth rate of population.

On reducing birth rates, Condorcet's own solution not only included enhancing economic opportunity and security, but also stressed the importance of education, particularly female education. A better-educated population could have a more informed discussion of the kind of life we have reason to value; in particular it would reject the drudgery of a life of continuous child bearing and rearing that is routinely forced on many third world women. That drudgery, in some ways, is the most immediately adverse consequence of high fertility rates.

Central to reducing birth rates,then, is a close connection between women's well-being and their power to make their own decisions and bring about changes in the fertility pattern. Women in many third world countries are deprived by high birth frequency of the freedom to do other things in life, not to mention the medical dangers of repeated pregnancy and high maternal mortality, which are both characteristic of many developing countries. It is thus not surprising that reductions in birth rates have been typically associated with improvement of women's status and their ability to make their voices heard—often the result of expanded opportunities for schooling and political activity.(28)

There is nothing particularly exotic about declines in the birth rate occurring through a process of voluntary rational assessment, of which Condorcet spoke. It is what people do when they have some basic education, know about family planning methods and have access to them, do not readily accept a life of persistent drudgery, and are not deeply anxious about their economic security. It is also what they do when they are not forced by high infant and child mortality rates to be so worried that no child will survive to support them in their old age that they try to have many children. In country after country the birth rate has come down with more female education, the reduction of mortality rates, the expansion of economic means and security, and greater public discussion of ways of living.


Development versus Coercion


There is little doubt that this process of social and economic change will over time cut down the birth rate. Indeed the growth rate of world population is already firmly declining—it came down from 2.2 percent in the 1970s to 1.7 percent between 1980 and 1992. Had imminent cataclysm been threatening, we might have had good reason to reject such gradual progress and consider more drastic means of population control, as some have advocated. But that apocalyptic view is empirically baseless. There is no imminent emergency that calls for a breathless response. What is called for is systematic support for people's own decisions to reduce family size through expanding education and health care, and through economic and social development.

It is often asked where the money needed for expanding education, health care, etc., would be found. Education, health services, and many other means of improving the quality of life are typically highly labor-intensive and are thus relatively inexpensive in poor countries (because of low wages).(29) While poor countries have less money to spend, they also need less money to provide these services. For this reason many poor countries have indeed been able to expand educational and health services widely without waiting to become prosperous through the process of economic growth. Sri Lanka, Costa Rica, Indonesia, and Thailand are good examples, and there are many others. While the impact of these social services on the quality and length of life have been much studied, they are also major means of reducing the birth rate.

By contrast with such open and voluntary developments, coercive methods, such as the "one child policy" in some regions, have been tried in China, particularly since the reforms of 1979. Many commentators have pointed out that by 1992 the Chinese birth rate has fallen to 19 per 1,000, compared with 29 per 1,000 in India, and 37 per 1,000 for the average of poor countries other than China and India. China's total fertility rate (reflecting the number of children born per woman) is now at "the replacement level" of 2.0, compared with India's 3.6 and the weighted average of 4.9 for low-income countries other than China and India.(30) Hasn't China shown the way to "solve" the population problem in other developing countries as well?
