I haven't had the chance to read the entire book yet (it is a brick and a half) but I would highly recommend the new WorldChanging tome. This is the new Whole Earth Catalogue (which I am also reading about in From Counterculture to Cyberculture - more later), which has always been near the top of my list of all time favorite books. WorldChanging provides a positive and action-oriented approach to the things that ail us and our increasingly grey planet. The associated website is also a great resource. The recent post on Slowing Down is a good example.
