I just discovered this cool little web comic about a leaf. It's called Rustle the Leaf and it's creators say they started it "to facilitate the sharing of environmental views in an engaging, nonconfrontational manner, and to introduce and reinforce environmental education with people ages 6 to 106."
It's a cute idea. Sort of a Smokey The Bear for the 2000s. I know a lot of people between the ages of 6 and 106, so I plan on spreading the word.
