L. Hunter Lovins defines natural capitalism at the Great Valley Center Conference on May 6, 2009. She explains why making money need no longer conflict with environmental and social good. That's the philosophy of "Natural Capitalism: Creating the Next Industrial Revolution," co-authored by L. Hunter Lovins, with Amory Lovins and Paul Hawken. Lovins and her colleagues present principles of practical economics that could carry us from our polluting past into a green future. Lovins is the founder of Natural Capitalism, Inc. and Natural Capitalism Solutions. She co-founded the Rocky Mountain Institute.
