You skipped the last part. Personally I am not happy going down the route of weighting the value of humans, but if we don't come up a solution to global warming that is politically actionable, somebody will start arguing that the west should do something about the rise of China and India. If we can only support 4 billion people on the planet, nobody will want to be in the group that has to be killed.
