Why it is important to have few or no children.

-- Richard Stallman

September 2012

French Translation

The most important thing you can do, avoid global heating disaster and make a positive contribution to the world, is avoid (as much as you can) having children. The numbers, which were calculated for modern America, say that having a child is roughly equivalent to 36 round-trip transatlantic flights per year.

Here is another article which presents the same data in a different way.

In what sense "per year"? The greenhouse gas burden of having a child is incurred all at once, by having the child, not gradually over time. The authors of the study divided that total by the parent's average life expectancy, which they took to be 80 years. It would be clearer to think of the burden as 2880 round-trip transatlantic flights total.

I decided not to have children for personal reasons. When I was young, my family was full of tension and anger, and then I noticed that many others were too. Such a family life was in no way attractive. When older, often I saw parents rebuke their children for playing with me, or even in my vicinity, assuming it would bother me — without waiting to see whether I did complain. (Often it did not.) Rebuking those children had become an ingrained, automatic habit. To see this made me sad for them, but I knew I would be the same as a parent. I would not be able to cope with a frequently crying baby without learning habits of reacting with irritation, too quickly and too harshly.

Many people tell themselves, "That happens to others, but I am better than they; I will get it right." Obviously, most of them are mistaken. I've learned not to fall into that kind of mistake; I did not suppose that I would succeed in human relationships in an area where most people fail.

Most fathers in the US have to work very hard to get money for their children. I did not want a life of running on a treadmill, doing whatever people with money would tell me to do.

A large fraction of US fathers eventually get divorced, and subsequently rarely see the children for whom they are spending most of their time scrabbling for money. What a futile life! But even those who are not yet divorced see their children little, since they are so busy at work. Meanwhile, single women with children do not have it easy; they usually confront poverty while carrying so much responsibility that one person can hardly cope — but that was not the risk that I personally faced.

I am convinced I made a wise personal decision in avoiding this. But I was not the only one that benefited from it — everyone did. Not having children is an important contribution to humanity. My decision probably reduced the 2050 population by 5 to 10 people.

Overpopulation is a tremendous danger to civilization and the ecosphere. It makes every human-caused ecological problem bigger. Population growth has slowed but not stopped. The human population is expected to grow by 2 or 3 billion by 2050, and it is not clear how we could provide water and food for all those people. Population growth also increases the difficulty of curbing global heating and thus the risk of the fall of civilization.

I conclude that the decision about having children is, for most people, the most important decision in their lives about affecting humanity's resource footprint in the future. (Nina Paley said this brilliantly in graphical form.)

My decision was a contribution in itself, but more than that, it enabled me to make a further contribution: to launch GNU and the free software movement. Having no dependents, I could dedicate myself to what seemed right rather than to whatever someone with money told me to do. I could decide to live on a minimal income, potentially for years, so I could achieve a triumph for freedom and cooperation. If you are reading this page, it is because that decision enabled me to make contributions to humanity that people appreciate.

I therefore urge you to do as I have done, and have no children.

I don't wish that nobody had any children; I don't want humanity to disappear. But there is no risk of that; no chance that my influence could be so great as to reduce the birth rate to near zero. Given the numbers I am likely to influence, the influence is all to the good.

Some argue that population decline is the real danger. In 50 years, they claim, everyone will have a comfortable life, so they may have few children (as tends to happen in developed societies today), and the human population could decline. If this went on for millenia, humanity might disappear — but is that a real possibility?

First of all, it disregards the tremendous disaster that global heating and destruction of the natural world are leading towards. 30 years from now, large parts of humanity will probably find it hard to get water and food, let alone contraception. It is unlikely we will provide most of humanity with a decent European-style life with the Earth's current population. There will be little chance, in that world, of population decrease due to many people's being comfortable. Rather, there will be rapid and gruesome population decrease caused by hunger and violence, along with illness exacerbated by pollution and by what we today call "tropical" pathogens, in the absense of today's advanced medicine and medical research capability.

I expect that reducing population growth now will make the disaster less drastic and actually increase the number of people who will survive it — and thus increase also the extent to which civilization and technology survive.

Supposing we avoid the disaster and eliminate poverty, 50 years later we might reach a stage where everyone prefers a small family. However, 50 years after that we will probably have greatly extended the human life span. That means a much smaller number of births per adult per year would be enough to maintain a stable population. The danger of overpopulation might even return.

The first hurdle is to avoid the disaster. Personally having no children will help, and it will free you to dedicate yourself to something else that will help.

Rebecca Solnit's essay, "The Mother of All Questions", presents an overlapping set of reasons for not having children in the way I wish I could have written them.


Many women lose all sexual desire after they have a child.


People who have one child face social pressure to have another. But you can resist the pressure.
