Are More Babies Better?

Two authors write about the same topic but about completely different subjects: Population.

Phil Cafaro writes an advanced review on Population and Climate Change for the WIREs Climate Change journal. The whole article is exclusively about how population size affects climate change.

But there’s also an effect the other way round: climate change affects population size. In John Broome’s new book on climate change there is a chapter entitled “Population” and pretty much the only topic is how climate change might decrease the human population (or increase it or eliminate it).

Funny how the two authors diverge so much in their focus. While Cafaro’s piece talks about population purely because climate change is bad, Broome’s chapter talks about climate change because a smaller population is bad.

I think Cafar0’s topic (population causing climate change) is more important than Broome’s (climate change causing population shrinkage). But at the same time, Broome is perfectly right to highlight the other side. It’s very difficult to come up with a coherent ethical view that would give no importance to how our actions affect population size. How come hardly anybody talks about that — the intrinsic value of a larger population — in climate policy?
