1. Do your homework. Read the EPA's "official" history of Earth Day.
2. Read a livelier history, which puts the first Earth Day into the early 1970s context—when the Beatles made their last album, fiber optics were first developed, and "Americans were slurping leaded gas through massive V8 sedans."
3. Plant a tree—it's a two-fer, you're also celebrating Arbor Day. Check out these tree planting kits available for home gardens as well as schools and other groups.
4. Eat locally. Celebrate with a meal prepared with foods from within 100 miles—a good way to conserve resources used for transportation and to support organic growers in your area. At our home base in the San Francisco Bay Area, the farmers' markets are overflowing with early spring treats and regional specialties: artichokes, asparagus, Meyer lemons, green garlic, all sorts of greens—drink a holiday toast with an organic chardonnay or cabernet. Do you have your own tasty local menu to tell us about?
5. Figure out your environmental footprint—no math skills required. Just take this easy quiz. You may find out how many planets it takes to support a person like you.
6. Treat your car to a day in the garage. Take a hike. Ride a bike. Ride the bus. Try out zipcar.
7. Join the crowd—at a big public event. View this city guide for Earth Day happenings around the world, in Washington, DC, and close to home.
8. Teach your children. Here's one of many good sources of activities to get kids involved with the environment and understanding the meaning of Earth Day.

Can-O-Worms is an innovative portable composter powered by good old earthworms. Made of 100 percent recycled materials, it can quickly turn kitchen waste into solid and liquid organic fertilizer— like gold to your garden. This wonder machine is simpler than it sounds. And don't worry: It's odorless.

Ken Smith, Organic Style's gardening expert (and worm advocate) adds: "What better way to get kids interested in an organic way of life than letting them 'feed' a whole worm community right in their backyard?"

Plant a billion trees? That astonishing number is the goal of the ever-ambitious Nature Conservancy's new effort launching this month. The Plant a Billion Trees Campaign to preserve and restore Brazil's Atlantic Forest sets the bar at an unprecedented height—but the threat is dire. "No tropical forest on earth has come closer to total destruction," says Claudia Picone, an information resource coordinator for The Nature Conservancy.

The Atlantic Forest is a spectacularly complex and biologically diverse expanse of tropical rainforest on the coast of Brazil. Once twice the size of Texas, only 7 percent of the original forest remains—it has been ravaged by ranching, illegal logging, agriculture, and other pressures. Read more about The Nature Conservancy's groundbreaking solution.

Each issue we ask our readers about good ideas for eco-living. Thanks to all who shared their tips with us. Here's this month's winning tip.

"I learned this from the women who lived through the Depression and World War II.  Whether you're at home, camping, or on the road for a picnic, give each member of the family a distinctive napkin ring and/or use cloth napkins of different colors.  Everyone gets a clean napkin in the morning and uses it for all meals and snacks during the day.  If it gets really soiled, it can be replaced with a clean one, but usually all we do with a napkin anyway is to catch crumbs in it and wipe our finger tips. As a result, we do only one small load of wash per week for all the cloth napkins, placemats, hand towels and dish towels that we use."
