GOOD excels at illustrating complex issues with infographics that are easy to understand and fun to look at. One of their latest addresses the relationship between bike commuting and obesity. I could try to explain it, but I think they do a better job of it:
The average American is both overweight and spends more than 100 hours per year commuting, that vast majority of those hours being spent in a car. Are those numbers correlated? Could we help reduce our societal weight gain by encouraging more commutes by bike or foot? Our latest Transparency is a look at the number of active commutes in several countries, as compared to those countries obesity rates.
Better yet, take a look at the graphic itself:
