Fad? Trend? Or the hallmark of a changing way of life? During Earth Month, CultureMap examines what green living means in the 21st century. We've asked our staff and a wide range of contributors to sort through the clutter and explain what going green means. Everyday people tell us how — and why — they have made green living a big part of their lives. We also offer ideas on how to be green on a budget and how to dress in an eco-friendly way. And we look at ways to make it easy being green — if you don’t get overwhelmed by all the possibilities.
