Colin Beavan (a.k.a No Impact Man) dedicated a year of his life to trying to reduce his environmental impact to zero. He stopped taking taxis, trains and elevators, only ate food grown within 250 miles of his home, left the power grid, stopped buying anything new and stopped making trash.

His inspiring book and blog follow his adventures, and attempt to distill from them a way for humanity to move forward without destroying the environment. No Impact Man’s approach is interesting as it focuses both inward and outward, calling into question the materialistic, wasteful and inefficient way we live our lives. He questions why we work so hard to buy things, when surely spending time with out friends and family will in fact bring us more happiness. This book is crammed full of interesting and surprising facts and figures, but is approachable enough to make a introduction to serious environmental issues.
