Bogota, Columbia is in a network of 40 cities fighting pollution. reports on what some of the world’s biggest cities are doing about pollution. C40 is a network of 40 large cities and claims that all together they account for one-eighth of the world’s population. New York Mayor Michael Bloomberg chairs the group. Just looking at the list of cities is a geography lesson. Curitiba, Brazil, anyone? Curitiba means “Pine Nut Land” and it has 1.76 million people. (Joy loves pine nuts.) (The list has to be incomplete, by the way, because we think China alone has 40 cities bigger than Curitiba.)
