So you think you're helping the planet if you drive a hybrid or use recycled paper products. There's much more to living green than those things. There's building green but most of us don't have a chance for a do-over. We have to make do with what we have and modify it and renew it. But after a tornado in Greensburg, Kansas, that town got to remake things anew. Architect Daniel Wallach is in town to talk about his experience. And the founder of Treehugger.com is also visiting. He also created the site, lifeedited.com, which offers plenty of suggestions for living green and simplifying your life.
