I feel fortunate to be part of the green blogosphere, as there is no shortage of smart, informed and thoughtful sites to visit. And here's another to add to your reading list: Earth and Industry.
Earth and Industry was started by Tim Hurst of ecopolitology and Green Options. The site is a discussion about the intersection of people, planet and profit and how these drivers can lead companies to maximize profits while being responsible and helpful citizens of the planet. It's sure to keep you well-informed, so check it out.
(I am a contributing writer to the site (first post: "What Ever Happened to the Climate Bill?") - although I was a reader of it before I was asked to write for it! Check out the other contributing writers here.)
