Want to slow climate change? Stop having babies

Q: So. What seems to be the problem?

A: There are 19 million adoptable orphans, and there’s catastrophic climate change on the horizon. Contributing a child to the world both makes climate change worse and, if we don’t get our act together, it might actually not be all that great for the child either.

You have two tracks. You could say climate change is a big structural problem, so it requires a structural solution; that’s a policy question. Or you could say a problem like climate change requires that we change our culture of individual obligation, and everybody needs to think about having small families.
