If global warming empties India – ‘The rapid evacuation of the tropics would cause migrants to concentrate in tropical margins and the subtropics, where population densities would increase by 300 percent or more’

Populations of early human settlers grew like an invasive species, Stanford researchers find – ‘Unchecked growth is not a universal hallmark of our history, but a very recent development’

By Rob Jordan5 April 2016 (Stanford Report) – Bustling cities, sprawling suburbs and blossoming agricultural regions might seem strong evidence that people have always dominated the environment.
