In honor of Earth Day, I wrote what may start off as a pessimistic run-down of how to green your life, as well as a guide to green labels. So there. Everybody guzzle plastics! There's no escaping them. But what do they mean? Still, the planet will probably do just fine without us. Maybe we should have a "People on Earth Day," since the resources we seem to be ruining are what keep us hanging here.
