Ask not what you can do for the environment, but what the environment can do for you? This Earth Day — thanks to all the companies and organizations trying to connect with the eco-crowd — you can ask both. Start by taking advantage of these free deals:

>> Environmental news site Grist’s offering Wake Up and Smell the Planet: The Nonpompous, Nonpreachy Grist Guide to Greening Your Day as a free download. Just register with the site to get a copy of the e-book — and to get into a drawing for a trip to the 2009 Bonnaroo Music and Arts Festival in Manchester, Tenn., in June.

>> Fresh & Easy Neighborhood Market stores will give away free reusable canvas bags to shoppers who spend $10 or more on Earth Day, April 22. Can’t make it to the store on that day? Signing up for Fresh & Easy’s newsletter will give you a coupon for a free canvas bag that you can redeem during your next visit.

>> For a more compact reusable bag, enter to win a Calypso Studios S.H.O.P. Tote. The company’s giving away $10,000 worth of these foldable reuable bags. Just register on the site by noon on Earth Day, April 22, to get into the drawing.
