Colin Beavan decides to completely eliminate his personal impact on the environment for the next year. It means eating vegetarian, buying only local food, and turning off the refrigerator. It also means no elevators, no television, no cars, busses, or airplanes, no toxic cleaning products, no electricity, no material consumption, and no garbage. No problem - at least for Colin - but he and his family live in Manhattan. So when his espresso-guzzling, retail-worshipping wife Michelle and their two-year-old daughter are dragged into the fray, the No Impact Project has an unforeseen impact of its own.
