Stewart Brand gave a TED talk recently ( http://www.ted.com/talks/stewart_brand_proclaims_4_environmental_heresies.html http://www.ted.com/talks/stewart_brand_proclaims_4_environme... ) in which he said that people moving into urban areas have less children, and much of the world was moving into urban areas these days. Hopefully the population will start to decline due to lower birth rates... I hope at least. :)
