What better way to observe Earth Day on April 22 than by recycling? And don't stop with bottles, newsprint and plastic. Aid for AIDS International allows you to get into the spirit of global regeneration by donating your unused HIV meds (from an old combo, say) and antibiotics to people around the world who need them. Go to aidforaids.org (212.337.8043) to contribute drugs or money—or to volunteer.
