This short video of how a pug can go green, while silly, is perhaps the most enjoyable Earth Day-related item to cross my desk. It can't help but make you smile or laugh.

In this video, which I spotted on the Sierra Club's The Green Life website, a pug sorts paper from plastic, rides mass transit and swaps carrots for cows.

It was made by The Daily Puglet blog for the 40th anniversary of Earth Day this Thursday and posted on YouTube (watch above or click here.)
