the importance of geography, population growth - great post from Benjamin Hennig

A great post by Benjamin Hennig on population growth, geography, and sustainability. Hennig writes
Geography matters because where populations increase and where they decline is highly relevant for finding solutions that provide a better future for all of humanity. While we are already producing enough food for 10 billion people, as shown in a study published in Nature, we do not manage to distribute this fairly so that hunger is a persisting problem. A population of 9, 10 or even 11 billion does not have to be a disaster if humanity makes more effort to minimise its environmental impact while providing a sustainable basis for how many people there are in the world.
Meanwhile, here's an animation of the world sized by people living on less than $1/day to those earning over $200/day from Worldmapper (© Copyright 2006 SASI Group (University of Sheffield) and Mark Newman (University of Michigan)). (note that the animation below is in Flash)
