I recently came across Hans Rosling’s Gapminder. This site has some of the best statistics, videos and other resources that provide realistic representations of global population growth, life expectancy, health, wealth, etc. In the last couple of days it has certainly displaced quite a few myths that I was harbouring. Gapminder has also reinforced my optimism for our future. Certainly challenges remain, but we are an adaptable and intelligent species.
This is a good Gapminder video to get you started!
