Cost = $1, benefit = $9
Tianjin, China (one of the ten most polluted places on the planet)

In the IHT this week, there is an interesting piece (together with the gruesome images) on the Top 25 Dirtiest Cities in the World. There are also slide shows on the world's densest cities and the world's most polluted places. These are not league tables that one would want to be part of and the sad thing is, to clean up the worst of the mess doesn't really cost that much vis-a-vis the benefits. According to WaterAid, for every $1 spent on improved sanitation, the benefit equals $9 resulting from decreased cost of health care and increased productivity. Seems like a good business proposition to me.
