I've been doing a lot of things to go green, like using canvas bags at the store, using cloth napkins, reusable water bottles, eco-friendly cleaning products, and have begun to use cloth diapers. It's a hard pill to swallow (especially for myself) but my biggest tip would be to do less shopping and consume less. For many of us, shopping is a pasttime but when you think about all the resources and transportation that go into producing consumer goods, buying less would really help the environment.
