Overpopulation and Living Forever – Part 2

Many worry that radical life extension or the elimination of death will lead to overpopulation and ecological destruction. In other words, while it may be best for individuals to live forever, it might be collectively disastrous. Readers may recognize this situation as an instance of the “tragedy of the commons.” Acting in their apparent self-interest, individuals destroy a common good. It may be convenient for individuals to pollute the air, earth, and water, but eventually, this is catastrophic for all. However, I don’t believe that overpopulation and its attendant problems should give researchers in this area pause. Here are some reasons why.

Let’s begin with a few simple things. First of all, fertility rates are currently plummeting around the world. In addition, the carrying capacity of our planet in terms of population depends on our technology, which is constantly progressing. Technology itself may allow us to comfortably feed more people with less environmental impact in the near future. Next consider that if the choice is between using technology to prolong healthy lives or have more children, most of us would choose the latter. Wouldn’t you prefer to have fewer children than having your parents get Alzheimer’s?

But there’s more. If we have conquered death, then we may already be transhumans or post-humans living after a technological singularity. Such beings may not want to propagate, since achieving a kind of immortality is a major motivation for having children. Posthumans would be relatively independent of the physical environment too—their bodies may be impervious to environmental stressors, or they may not have bodies at all. In such cases, concerns about overpopulation would be irrelevant. I’m not saying that they will be irrelevant, but that the tragedy of 150,000 people dying every single day—100,000 of them from age-related causes—is a huge price to pay for speculative hypotheses about the future. We shouldn’t assume that our concerns as biological beings today will be relevant in the future.

Of course, I don’t know how the future will unfold. But preserving the minds that now exist may be a better survival strategy than educating new ones. In the future, we will probably need educated and mature minds—their invaluable knowledge and wisdom. So I argue that we should try to eliminate death, dealing with overpopulation—assuming we even have to—when the time comes. My suggestions may be considered reckless, but remember there is no risk-free way to proceed into the future. Whatever we do, or don’t do, has risks. If we cease developing technology we will not be able to prevent the inevitable asteroid strike that will decimate our planet; if we continue to die young we may not develop the intelligence necessary to design better technology. Given these considerations, we shouldn’t let hypotheticals about the future deter our research into defeating death.

Note too that this objection to life-extending research could have been leveled at work on the germ theory of disease, or other life-extending research and technology in the past. Don’t cure diseases because that will lead to overpopulation! Don’t treat sick children because they might survive and have more children! I think most of us are glad we have a germ theory of disease and treat sick children. Our responsibility is to help people live long, healthy lives, not worry that by doing so other negative consequence might ensue. We are glad that some of our ancestors decided that a twenty-five-year life span was insufficient, instead of worrying that curing diseases and extending life might have negative consequences.

Most importantly, I believe it is immoral for us to reject anti-aging research and the technologies it will produce, thereby forcing future generations to die involuntarily. After anti-aging technologies are developed, the living should be free to choose to live longer, live forever, or even die young if they want to. But it would be immoral for us not to try to make death optional for them. If we made decisions for them, we would be imposing our values on them. At the moment we tolerate a high death rate to compensate for a high birth rate, but our descendants may not share this value.

Moreover, as I have argued previously, death is like a bomb strapped to our chest. The bomb is with us from birth and can detonate at any time. If it is in our power to remove that bomb for future generations, then we should. We should not let hypothetical concerns about negative consequences deter our removing those explosives. I’d bet future generations will thank us for removing such bombs, and even if our descendants do decide that a hundred years of consciousness is enough, they will probably be thankful that we gave them the option to live longer. I’d guess that higher forms of being and consciousness will want to preserve their being. They would want us to disarm the bomb.

The lovers of death don’t want to disarm the bomb because its detonation transports you to a better address—from a slum to a mansion. Even better, in the mansion, your mind and body are eternally bathed in a salve of peace, love, and joy. That is the justification for opposing the bomb’s removal. The problem is this story is fictional. And we know that most people agree because when humans conquer death, when they learn to remove the bomb—they will. Those in the future who have the option to live forever will be eternally grateful that they have the real thing, instead of the empty promises we now pay for each Sunday in church. Consciousness has come a long way from its beginnings in a primordial soup, but there is so much farther to go. Let’s put our childhood behind us, and make something of ourselves.

  1. Hey John,

    Sorry about my english, its not my main language.

    I’ve been following you for a while, and i almost always enjoy your interesting works and thoughs, but sometimes i can’t deny that you sound excessively scared by the concept of death to me. Couldn’t be this due to a excessive restrictive concept of personal identity?

    Do you know Derek Parfit’s works about identity? (Reasons and Persons mainly) As i suposse that you do, What do you think about them? His ideas about personal identity where really helpful to me in my aim of confronting my own mortality in a secular and analytic way..

    When i finally understanded his arguments, i couldn’t but share the feeling he express in the book:

    “My life seemed like a glass tunnel, through which I was moving faster every year, and at the end of which there was darkness… [However] When I changed my view, the walls of my glass tunnel disappeared. I now live in the open air. There is still a difference between my life and the lives of other people. But the difference is less. Other people are closer. I am less concerned about the rest of my own life, and more concerned about the lives of others.”

  2. This is a great insight and similar to the one Bertrand Russell had which I talk about in this blog.

  3. Most people want to have children more than they care about their parents staying free from Alzheimer or any other deadly disease. After keeping themselves with a good life quality almost all people have a need to have children and the vast majority want at least the first child to be their own. If they wanted their parents to not have alzheimers they would prioritize their parents health over having children. The only people I see prioritizing their parents health are those with no children and I’m sure not all of those prioritize their parents but prioritize themselves their spouse, pets and/or various indulgences. Many without children I’ve known of are poor and often also with mental or intellectual problems. Maybe due to their problems procreation never gets off the ground. Bottom line? Most people care far more about having children than the lives of their parents. The number of people in assisted living moreso even than in home care and care homes highly indicates this, as most of these in supported senior living have children who are not in poverty.
