Kurt Vonnegut once wrote of a discussion with friend and fellow author William Styron, in which they tried to determine what portion of the people on Earth have lives worth living.

The figure they arrived at was 17%—about one in six people.

On a good day I can tell myself that number must have gone up since then—that we've made progress in battling poverty and disease on a global scale. Maybe it's up to 20% or even 25% by now. On a bad day I'm certain that they were being far too optimistic and that things are bound to get worse.

In the coming decades humanity is guaranteed to face mounting ecological crises as a result of the pollutants we've already pumped into the atmosphere. This is likely to feed into current political trends toward nationalism, as tens and hundreds of millions of climate refugees are forced to seek safe haven around the world.

Countries will seal up their borders and churn out propaganda about the inhuman hordes pounding at the gates—the crime, the diseases, the vermin. If we aren't careful, full-blown eco-fascism will take hold. The climate crisis will become a powerful excuse for state-sanctioned violence, oppression, and racism, and the coming generations will relive horrors that were supposed to be behind us. Those are the threats we face even if we defy current political trends and pass sweeping climate legislation—finally beginning the hard work of avoiding total ecological collapse.

Given the scale of the problem, the choices we can make at the individual level are inadequate, but still valuable. I cut out red meat, I avoid driving as much as possible, and I try not to buy a lot of stuff that I don't need. If millions of people made the same changes…it would probably be better than nothing. Of course the reality is that I still produce far more ecological damage than the average person on Earth. Some of that is unavoidable—a product of living in the US —but I can't deny that a lot of it is because of the way I live. There are certain things I don't want to give up. I travel. I eat dairy. And my wife and I are planning to have kids.

Whatever other decisions you make with your life, none are likely to have as much impact as deciding to create another life—another human to eat and travel and make imperfect decisions. Another human to wrestle with difficult questions and fear for the future. How can we justify the decision to force life on another person in a dark world? Another person whose life we can only try our best to make worth living. Another person who will, in many ways, add to the collective problems of humanity. I'm not going to claim that it's an easy decision to justify, and I don't fully expect to convince anyone who disagrees with our decision. As much as anything, this is an attempt to articulate a hazy justification for myself—and possibly to bolster my rationalization.

The aspect of being a parent that most excites me is the opportunity to reinvest in the future. After multiple decades of passionate concern for the planet—all while people with the power to effect positive change have done nothing—it's hard not to become a little jaded and complacent. Now that prominent political figures are finally pushing for the kind of societal transformation we need, I want to have a stake in fighting for a world that can sustain life beyond my death.

If I'm going to invest in that hope, I have to believe that—despite the ecological impact—it's still possible for a person to make the world a better place. And I want to believe that the people raised with care and love and positive intention are exactly what the future needs. Having a child—and caring for them, teaching them about our complicated and frightening and beautiful world—is a manifestation of that belief. I want the surprises and challenges that will come with parenting, and I want the pressure to contribute to something greater than myself—both in my personal life and my engagement with political change. I want a connection to the future of humanity that this fight is all about.

Of course, I can get all of that through adoption, and get it without forcing existence and the challenges of life on a brand new human. My wife and I do intend to adopt—or at least to be foster parents—down the line. But right now the window to have children of our own is closing. The financial burden of raising a child is so daunting that we would probably put it off for another decade if we could, but we can't. There are biological pressures that can't be ignored. Our bodies are getting older. The safest time to have kids will soon be behind us. If we could satisfy ourselves to raise adopted children, then we could wait until we reach some hypothetical state of readiness—prepared for the endless crises of raising a child. That state probably doesn't exist, but why is adoption not enough for us?

To suggest that the answer is anything but selfishness would be a lie; but, love is in some ways a selfish emotion. Being selfish for each other and selfish as a unit is part of what makes love worth all the pain and the effort we put into chasing it. We love what we are together, and we want good things for that union. We love us.

The bond and belonging between us is a strong comfort in a world that's dominated by so much loneliness. And as much as we believe that we could extend that bond to any child who needed to belong, there is something beautiful and exciting (and selfish) in the thought of using that bond to bring a new life into the world—a new person, autonomous and unique, but a person who embodies aspects of us both and of what we love about each other.

It's the idea of transforming what we are to welcome that new person into our bond. Life at its best is transformative and a little bit frightening. What could be more transformative and frightening than the process of pregnancy, birth, and parenthood? I can only be supporting staff in much of that process, but I'm still excited by the prospect.

Maybe this is all just a muddled translation of my evolutionary function. That excitement might be a purely biological impulse. But there are limits to denying biology. At the base, biology drives everything we do. Regardless, at this point we are committed to having children of our own—or committed at least to trying. If it weren't such a common choice—if friends weren't choosing the same; if our families weren't also excited for us to pursue that selfish impulse—we would probably be shamed out of it. Instead, we just worry about being good parents while people with experience try to reassure us that the worry gets us halfway there.
