I see you an a lot of other people in this thread arguing in two completely different frameworks. Your counter didn't address the parent's claim that economies of scale improved our life immensely, you just pointed out that there is a cutoff on how many people the earth can support. I think both points are true and in no way mutually exclusive. I will just highlight that while what your say is true, there _must_ be some upper bound where a high enough population will mean living on earth will become unsustainable, I would NOT use that as the most immediate threat seeing how: 1) We are still quite a bit off from the 16 billion figure you quoted. 2) The global trend is population shrinking, not population increase. 3) As proven in the past, technology does tend to allow us to greatly increase the carrying capacity of our environment.
