1. Go into a field full of methane-emitting cows and/or TeaBaggers and cork them.
2. Turn off my car's ignition after I've parked it in the garage instead of leaving it running in case I need to make a fast getaway.
3. Rent a helicopter (that runs on used cooking oil!) and airdrop thousands of plastic recycle bins over Houston to create awareness of this important issue.
4. Create "teachable moments" throughout the day by pointing at people drinking out of plastic water bottles and yelling into a bullhorn, "Resource-sucking energy whore!!!"
5. Insert Breathe Right nasal strips inside my nostrils so that I actually breathe less.
6. Start a coral reef in the bathtub for eventual relocation to the coast of Australia.
7. Harness solar power by using nothing but the sun and a magnifying glass to light my joint.
8. Combine bicycling and public transportation by attaching a grappling hook to the back of a metro bus and having it tow me and my Schwinn into town.
9. Practice water conservation with two everyday objects: a chamber pot and an open window.
10. Finally, hit myself repeatedly in the face with a two-by-four while blindfolded so I can get a sense of Earth Day from the perspective of a climate-change denier.
Thanks to Bill in Portland Maine.
