"There is a fire burning over the Earth, taking with it plants and animals, ancient skills and visionary wisdom. At risk is a vast archive of knowledge and expertise, a catalogue of the imagination, an oral and written language composed of the memories of countless elders and healers, warriors, farmers, fishermen, midwives, poets, and saints. In short, the artistic, intellectual, and spiritual expression of the full complexity and diversity of the human experience. Quelling this flame, and rediscovering a new appreciation for the diversity of the human spirit as expressed by culture, is among the central challenges of our times." Wade Davis, 2009 Massey Lectures
