I was honored to be asked to kick off MIT Sloan sustainability series. Jeffrey Immelt, CEO of General Electric, followed me a few months later. He talks about what a business can do with its business practices to reverse the problems that business has created. In my talk, I am asking businesses to see themselves as part of a living system, and to learn to be a integral aspect of the working of that system. In other words, Immelt is talking about problems and I am talking about potential–both are important, but it is important to know what they can each produce.
