For context, I'm very neutral on the matter so take the following as just a musing on the topic. I'm not really familiar with the stats here, so do pardon if I'm starkly mistaken, but it would seem intuitive that having a child in countries A and B would have a different impact based on how developed countries A and B are. If a kid from A grows up to own a car, fly around etc, and the kid from B cannot afford to, the footprint difference between these two individuals would be considerable. This is obviously only looking at a single child, how the fact that people in more developed countries tend to have less children plays into this and pushes the balance one or the other way is unclear.
