Can clearly see your bias here. Why are you ignoring the emissions by the rich 1B people, they are the ones that can actually do something about it (reduce consumption and invest in research) thanks to their relatively luxurious lives. The others are just trying to survive - for them, consequences of climate change are still much better than the current state of poverty.
The rest of the world has a very low carbon footprint per person, just that the population is much higher. How do you propose reducing the population, birth rates have already been dropping drastically across the globe and human population will peak at ~10B. Do you want to kill them off? Do you feel your life is more important than theirs?
