Recycle, schmecycle. These days, saving the Earth requires a lot more than just collecting cans.

1. Build Your House Out of Tires

Two decades ago, architect Michael Reynolds realized that a tree-hugging utopia would never be possible if homes weren't inexpensive, easy to build, and environmentally friendly. His solution? The Earthship.

While living in an Earthship may take more work than living in a split-level in the suburbs, the eco-friendly homes have become surprisingly popular. Several Earthship subdivisions have opened up in the past few years, including the Greater World Earthship Community near Taos, New Mexico, which was founded in 1994. Greater World residents build their own homes and, in an interesting twist on subdivision bylaws, are expressly forbidden from hooking up to public utilities or digging wells on their land. Here are photos of a few Greater World Earthships:

2. Fight Oil Spills with Mushrooms

In the war against ocean pollution, environmentalists have a new ally in mushrooms. As nature's morticians, mushrooms have the unique ability to take dead things and make them pretty again by turning decomposed matter into nutrients. In fact, they're so adept at tearing down and rebuilding chemical compounds that even oil spills are no match for their natural abilities.

3. Dumpster-Dive for Dinner

As the name suggests, freeganism is an off-shoot of veganism, meaning that most practitioners avoid all products made from animals. But the "free" part refers to how freegans get their victuals. Method No. 1? Digging through the dumpster.

According to the Environmental Protection Agency, Americans pitch 245 million tons of waste a year, much of which is salvageable. In addition to unfashionable furniture and clothes, plenty of edible food ends up in the garbage. According to unofficial freegan spokesman Adam Weissman, that waste is directly tied to capitalism, which freegans see as an oppressive economic system. To avoid contributing to it, they become scavengers—collecting the vast majority of what they eat, wear, and use from other people's garbage. Often, these "urban foragers" will meet in designated locations at designated times to rummage together in a group, typically focusing on dumpsters behind retailers, offices, schools, and other places of high-volume disposal.

It's not as beggarly as you might imagine. Most freegans aren't homeless, and many of them have 9-to-5 jobs. They eat pretty well, chowing down on practically fresh veggies, day-old bread, and canned goods. Food poisoning is a risk, but smart freegans know to skirt bacteria-prone produce and avoid canned goods that are bulging or oozing. They're also big on community involvement. Veteran freegans train newbies in dumpster-diving technique and foraging for wild plants. They also organize "freemarkets," where goods and services are given away or bartered instead of sold. In fact, many trade goods via a Web site called freecycle.org, and the community even has its own section on Craigslist.
