One of my many interests is recycling and green living. Crafting a Green World describes itself in this way:
Crafting a Green World features do-it-yourself projects that incorporate reused, recycled, and natural materials. Find knitting, sewing, crocheting, and other project ideas for eco-friendly and fashionable clothes, crafts, gifts and more.
Earth911.com provides information to help locate areas to recycle many, many materials and articles about these materials.
I recently heard a podcast about using less stuff. (Can't remember where.) It is such an obvious solution to our overuse of limited resources, but I had not heard about it in the way it was presented. I found this site that has articles and research on ULS.
An interesting podcast called Green Talk Radio with Sean Daily presents many different topics to help us and those around the world live more eco friendly. Here is a site with a synposis of the podcasts.
