I think this misses what the question should be. It's not whether to have children. It's HOW MANY children.
FWIW I have two. My wife and I wanted kids. We also did not want to contribute to the population explosion. YMMV.

The point is to slow down the population growth, by not having kids, and improve a bit the predicted future for those who do end up having kids.
