This week on TreeHugger Radio
This week on EcoTalk, TreeHugger Radio brings you world renowned British economist Sir Nicholas Stern's report on the science and economics of climate change, and the "greatest market failure the world has seen." Hunter Lovins comments on the brighter side: a contrasting study commissioned by Royal Dutch Shell, which finds some trillion dollars to be made in the next five years in clean, green business worldwide. We also caught up with James MacKinnon, creator of the 100-Mile Diet, for a bit more on what it all means. Stay tuned next and every Thursday to EcoTalk for TreeHugger Radio.
