Yebbut this thread is about human-induced climate change. No-one is denying the other issues. But global warming is caused overwhelmingly by big developed countries with low birth rates and high energy consumption. You're the one provoking argument by trying to widen the issue to blame just "people" instead of focusing on the actual people who are doing the damage. There are billions of innocents with regard to climate change. The energy-consuming monster is the big developed countries. Those other billions of people can only dream about having the energy at their disposal that those countries have. Back to your graph. Any solution you can come up with for controlling or reducing population in developing countries will have little or no impact on global warming. It's for a different discussion, old chap.
