FORTY CITIES FIGHT POLLUTION

C40.org 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.)

IF PICASSO PAINTED SUPER HEROES

FITNESS FOR GEEKS

“Fitness for Geeks,” by Bruce W. Perry, $35 from oreilly.com, or $23 at Amazon.com, is all about diet and exercise to fit a geek’s needs. That means no bit of information is left out. Did you know that nearly a third of Americans so lack Vitamin C, they nearly have scurvy? That’s a disease sailors used to get on long voyages — till someone thought of packing along lemons and limes (which is how British sailors came to be called “Limeys.”) Captain Cook brought along sauerkraut and carrot marmalade on his famous voyage. Worked just as well.
