"Sharing really is going to save the world!" declares Janelle Orsi, author of The Sharing Solution, noting that it's fun, doesn't require special skills -- and we can start now. She and Jennifer Kassan co-founded the Sustainable Economies Law Center to help people formalize collaborative structures like producer cooperatives, cohousing developments and tool lending libraries. They're working to reduce the hurdles to investing in locally-owned and locally-controlled enterprises. No wonder law students are excited to intern with them!
