I enjoyed listening to the eco-friendly ideas the people submitted for the Big Idea Contest. The negative thing about a contest though, is that we should be encouraging all ideas, not matter how small. It doesn't have to be a "winning" idea to have value. Every idea that helps move us toward a sustainable, eco-friendly, green life style has merit and value. A contest however, helps generate ideas... That being said, you may want to take a look at the ideas people submitted. I had trouble downloading these on my computer. It ran really slow. Aside from that, it was fun listening.
