The environmental movement and the rising awareness of global warming have spiked an interest in green living. It's not just recycling now. People want to know what they can do to live sustainable lives. What changes do they need to make as consumers and citizens? What are the relative impacts of the changes-that is, which will have the greater impact? They've made up their minds that green living is their goal, so they're not asking for a sermon. They just want simple, how-to facts.
