What would your life look like if you made a commitment to have zero impact on the environment? Self-proclaimed guilty liberal Colin Beavan tackled this question in his own life, embarking on a yearlong experiment that affected his wife, their toddler, and even the family dog. They nixed takeout food to avoid reams of wasteful packaging; walked or rode bicycles; used no electricity in their apartment—no TV, no home Internet access, no air-conditioning, no refrigerator, no brightly lit living room late at night; bought seasonal, local groceries that carried the smallest possible carbon footprint; switched to cloth diapers; and otherwise reinvented twentieth-century living. By turns poignant and provocative, No Impact Man reports on the surprising results of this journey, with inspiring words for anyone who has ever wondered what difference “just one person” can make.
