Greenpeace pals Seventh Generation and are running an über-cool contest called "Convenient Truths." It works like this:

1. Grab a video camera.

2. Do something to inspire your peers to stop global warming

3. Submit video

4. Save the world. And win prizes!

You've got until February to put a 1-2 minute production together.

The "sustainable prizes" include an eco-trip to Alaska, solar bikes and backpacks, and more of the green gear you'd expect from the design-obsessed and hippy-hearted folks at Treehugger.

Winning videos will be broadcast and the Top 10 videos will be packaged on a DVD and distributed by Ironweed Films. More from (Thanks, Jessica!)
