My daughter and I listened to this audiobook last weekend, on a long drive and while painting. Part of their No Impact plan was no motorized transportation, and involved bicycling in New York City traffic. But what struck me about the book (and the documentary movie) was how his experiment engendered the same type of hate mail that cyclists get.

His experiment was to live in their 9th floor NYC apartment with their toddler and dog, and have zero impact on the environment,for one year. No trash, locally grown food only, no motorized transportation including elevators, they even shut off their electricity.

I definitely recommend the book. I don't bike because I'm "green", I bike for other reasons including that I'm cheap, but I see environmentalism as a happy side effect of my bicycling. It was an interesting, enjoyable read, and even better that both my 14 yr old and I liked it. Although we felt uncomfortably ironic listening to this in a portable CD player that runs on AA batteries.
