Here are two useful sustainability resources:
1) _Plan B 3.0: Mobilizing to Save Civilization_, a new book by Lester Brown. The entire book is available FREE as a pdf here.
Brown is director of the Earth Policy Institute and long known as one of the world's leading environmental thinkers. This book examines the environmental threats facing our people and planet, and proposes radical changes toward sustainability. Did I mention that it's FREE?!
2) American Public Media maintains a sustainability web site.
The site includes sustainability stories gathered from the APM family of radio programs (e.g. Marketplace, Weekend America, Speaking of Faith, American RadioWorks) and other sources; web-exclusive material, including blogs, multimedia stories and interactive features like Consumer Consequences, a game where visitors can calculate their impacts on the planet.
The site "aims to become a forum for the whole range of perspectives on sustainability" and to "be a vehicle to help us find not only experts to inform our journalism, but people with practical knowledge of sustainability issues from their own lives, jobs, and families."
In particular, check out the 'Greenwash Brigade' blog. Its writers are "environmental professionals on the hunt for 'greenwash'," examining "eco-friendly claims by companies, governments and other groups," and asking "tough questions about the mainstreaming of green."
