In the wake of the BP oil deluge in the Gulf and the Chevron oil spill in Utah, calls for renewable energy and sustainable living have been redoubled, with even President Obama getting into the act. To see what sustainable living can actually look like, Ben Evans, Julie Dingman Evans and Mark Dixon took a road trip across the U.S. in a hybrid car with only a few rules: they created less than one shoebox of garbage each month, never turned on an incandescent light and used approximately 25 gallons of water per person per day.

Laura caught up with Ben Evans to talk about the project, called YERT: Your Environmental Road Trip. The crew are working to finish their documentary on their adventure and looking for donations, if you'd like to chip in.
