Do you feel guilty about how you treat the planet Earth? Read No Impact Man and you will still feel guilty but may want to make changes to your life. Colin Beavan wanted to do the ultimate experiment and live year with his wife and child have no impact on the environment and at the same time keep a running blog on his progress. Good Luck. Agree or disagree with Colin, you must respect his efforts. All the research he did and all the changes he made in his life are far too numerous to mention here but let me say he has a very understanding spouse.
