I've ranted about Earth Day before - in 2007 and 2008. (2008 has some perspective on the "evolution" of Earth Day, since the first one in 1970.) So I'll refrain this time around.
My "convenient truth" - I turned off our outside lights first thing this morning. (I swapped out the traditional bulbs for CFL twisty bulbs a few months back. They wouldn't be on at all, 'cept for the insistence of the Missus. She's convinced that they deter escapees from Maximum Security and the Mental Hospital.) I didn't let the water run while I brushed my teeth. And I hopped on the bike, just like every day, for the commute... through our picture-perfect Earth Day weather. Far as I can tell, so far it would take those CSI people to find any evidence of my having been here. Which is good - the best way to be a good steward for our lovely Home Planet is to "leave no trace."
I hope everybody has an awesome Earth Day.
