Population Control and the Environment

Birthrates continue to drop in the West. In many countries, the birthrate among citizens in well below the replacement rate. This means that, without immigration, the population of a nation will begin to shrink rather than grow. Some believe a reduction in the overall population of humans on earth would be a good thing.

There are many reasons that people are having fewer children. Some cite economic concerns, career interests, and avoidance of the responsibilities of parenting. Others cite the prevalence of entertainment that distracts and seems to replace the need for human relationships. But some people are not having children because of concerns about the environment.

In a 2019 article in the online magazine, Outside, one author celebrated his recent vasectomy. He claims that his choice of voluntary sterilization was necessary, “because there are simply too many humans on this planet.” He argues that reducing the population is absolutely necessary, “and getting there voluntarily will be an awful lot less painful than doing it with war, famine, and natural disaster.”

Throughout much of its history, the environmental movement has tended toward negative attitudes about human reproduction. The embrace of population control as a goal by many environmental activists has served to make agreement between many Christians and non-Christian environmentalists difficult.

Christians should be concerned about efforts to reduce or control human population because they often lead to violence against the most vulnerable.

The Environment and Population Control

Historically there has been a strong connection between environmental movements and population control. At the tail end of the eighteenth century, Thomas Malthus, an English clergyman, proposed delaying marriage and other means of reducing birthrates as a way to slow population growth. One of his major concerns was that a growing population would expand beyond the capacity of the agriculture of the day. This, he feared, would increase suffering as many people would starve because there was simply too little food.

In 1967, Paul Ehrlich published his famous book, The Population Bomb, where he predicted impending environmental catastrophe if the number of humans on earth continued to rise. Tillich’s thinking was used by a congressionally appointed team, the Rockefeller Commission, to argue for government funding of abortion, sterilization, and other forms of birth control. The measures recommended were voluntary, but they were to be state sponsored.

Are Kids Bad for the Environment?

For the sake of argument, let’s assume for the moment that climate change is strongly influenced by human activity. For many environmental activists, this assumption leads to the logical conclusion that fewer humans would be proportionately better for the world.

However, that conclusion does not necessarily follow without additional assumptions. In making this argument, proponents of voluntary population control are assuming that consumption patterns would continue exactly as they are now.

This is an example of an over-simplified argument leading to a seemingly inarguable conclusion. In fact, it is theoretically possible that, if consumption patterns of humans were sufficiently changed, the earth could support population growth at an even greater rate. Even accepting a strong correlation between human activity and climate change, it is unnecessary to embrace an unbiblical, negative view of humans for the sake of the environment.

The Goodness of Humanity

As Christians, we should actively oppose worldviews that denigrate the value of humans. Genesis 1:26–27 affirms that humans were made in the image of God.

The first command God gave to humanity was to be fruitful and multiple. Humanity was called to “fill the earth and subdue it, and have dominion over the fish of the sea and over the birds of the heavens and over every living thing that moves on the earth.” (Gen 1:28, ESV)

Part of God’s original design for the created order was for it to be filled with humans, made in his image.

Humans and the Environment

Genesis 1:28 which affirms the dignity and authority of humans, is also interpreted by some environmentalists as the verse that has enabled the abuse of the environment in the West. Such an interpretation is based on the belief that filling the earth and subduing it entails misusing the earth.

Given the track record of humans in Western nations influenced by Christianity, there seems to be some merit to the connection between a biblical worldview and the abuse of creation. However, consistent message of Scripture is that humans are to be responsible stewards of the earth. Even in Gen 1:28, the assumption is that by filling and subduing the earth, the created order will flourish in a way that supports the growing number of people made in the image of God.

The Danger of Population Control

Population control is dangerous because it tends to most significantly impact the most vulnerable. The near total abortion rate of babies diagnosed with Down’s Syndrome is Iceland is one example of voluntary population control that has led to humans, made in the image of God, largely eradicated because they were considered defective.

China’s radical one-child policy, which has since been somewhat relaxed, created a significant demographic problem for the nation. Culturally boys were valued more than girls, in part because they were perceived to have more potential to earn more and support parents in old age. Therefore, couples practiced sex-selective abortions, often choosing to abort baby girls. The result is a gender imbalance, with approximately 118 boys born for every 100 girls.

Population control tends to lead to the elimination of those considered less valuable by society, whether that is due to perceived defects, sex, race, or some other characteristic. A culture that values humans as made in the image of God should resist movements that promote population control as a legitimate goal. That goal has proved costly to those who can least defend themselves.

Conclusion

As citizens of the Kingdom of God, Christians must learn to think rightly about the good of humanity and the image of God. Despite the effects of the fall, Scripture consistently affirms the dignity and value of every human being. Population control movements tend to impact the most vulnerable more significantly. Therefore, Christians should be careful not to celebrate movements that make reducing the population of humans a central goal, even when those controls are implemented voluntarily.
