At last I spoke to someone with a systems perspective! I enjoyed the conversation with a fellow academic who cares beyond the classroom. Michael spoke about how many areas we could work in, not to say it's too much but that you can find a place to contribute. Many people wish there was a silver bullet. As far as I know there isn't one. His about-to-launch book, Can Business Save the Earth, treats action on the environment systemically, a perspective I consider essential for environmental leadership. What may seem initially overwhelming doesn't end up that way when you see the big picture, which is what his book covers, and when you find a place to act. Plus, his personal challenge is one a lot of people think about doing but don't, so if you've thought of changing your diet, I recommend listening to Michael's challenge.
