Is population control a good reason not to have babies?

The world’s population has reached seven billion and is still growing. In her new book, The Baby Matrix, Laura Carroll insists that if our culture keeps encouraging people to have babies we will destroy the planet. People who care will not have children, or if they must, they will have only one biological child. If that’s not enough, they will adopt additional children. The overriding theme of this book is that our “pronatalist” society’s belief that having children is the right and natural thing to do is wrong, wrong, wrong.

For baby boomers like me, Paul R. Ehrlich’s The Population Bomb, published in 1968, was required high school reading. In it, he predicted that if we didn’t do something about our ever-increasing population, the world would become so overpopulated it would self-destruct. This book became the bible for the Zero Population Growth movement. It started about the same time as birth control and abortion became legal for most people in the U.S., so people really did start having fewer kids. The average family produced two children instead of three, six or a dozen.

Still, Carroll says we need to cut back even more. When I talk to people who are childless by choice, many mention overpopulation as one of the reasons not to have kids. It’s rarely their main reason, but it’s one of them.

All of this makes me uncomfortable. Weren’t our bodies designed to make babies?

I was happy to find some articles that report the population has started decreasing, that maybe we’re not headed for disaster. This one from Slate, “About That Overpopulation Problem,” explains that some countries, such as Germany, have already lowered the birthrate so much that the overall population is going down.

With couples waiting until they’re older to have kids, with birth control being available to most people, and more and more choosing not to have children at all, it would seem likely that our population would stop growing. If not, I suppose the natural methods of population control that work with non-humans–predators, natural disasters, lack of food–would eventually balance out the numbers.

What do you think? Do you believe we should limit births to keep the population down? Has anyone in your life suggested this as a good reason not to have kids?
