On our 30th show we talk to professor Roger S. Gottlieb about his new book A Greener Faith: Religious Environmentalism and Our Planet's Future. Roger discusses the theory and practice of religious environmentalism as a counter to the religious fundamentalism and secular consumerism prevalent in today's world, and gives us hope for the future. Our second interview is with Hillary Rettig, a vegan activist who has written a book called The Lifelong Activist: How to Change the World Without Losing Your Way. Hillary gives us some ideas about how activists who are politically to the left can sustain themselves financially while still being true to their causes and not burning out. Vegan Radio's own Scott Lahteine is the musical guest on this show, sharing some electronica he created using his own guitar software for the Mac, FretPet.
