I recently saw an incredible documentary about a Manhattan couple who lived "no impact" for a year. This means they did all they could to drastically reduce their carbon footprint, for a whole year.

The documentary, No Impact Man, which opens nationwide this Friday, and the book written by No Impact man himself, Colin Beavan, a historian, shows you easy and challenging ways to reduce your impact on the planet.

Check out Walletpop's interview with Colin and his wife, Michelle Conlin, a reporter for BusinessWeek, on how much money they saved using candles instead of electricity, cutting out their consumerism habits, and buying organic produce from local farms. Colin is now working to help others make sustainable choices in their hectic, modern lifestyles through his No Impact Project. (Can I say "no impact" anymore? Just watch the video to find out.)
