I recently read the story of one man inspired to make a year-long journey into sustainability. He's writer Colin Beaven, but he goes by another name: No Impact Man. From a recent New York Times article about his project:

Welcome to Walden Pond, Fifth Avenue style. Isabella’s parents, Colin Beavan, 43, a writer of historical nonfiction, and Michelle Conlin, 39, a senior writer at Business Week, are four months into a yearlong lifestyle experiment they call No Impact. Its rules are evolving, as Mr. Beavan will tell you, but to date include eating only food (organically) grown within a 250-mile radius of Manhattan; (mostly) no shopping for anything except said food; producing no trash (except compost, see above); using no paper; and, most intriguingly, using no carbon-fueled transportation.

Wow, that's pretty radical. Nonetheless, we applaud his efforts. Colin's project reminded me a bit of a recent special I saw featuring Survivorman Les Stroud . He's trying to take his wife and kids into the wilderness of Ontario, and spend time off the grid.
