"Photosynthesis puts things together. Fire takes them apart." – Dr. Stephen J. Pyne. While many people talk of the "Anthropocene" – the age of humankind, when nearly every natural process seems to be affected by the actions of billions of individual people – Stephen Pyne reminds us that we also are living in the Pyrocene, the age of fire, and that the history of humankind is inextricable from the history of fire, the most elemental and implacable force on this planet. Join Hal in Queen Creek, Arizona, for a conversation with Dr. Pyne, 15 years a firefighter on the crew of Grand Canyon National Park; a renowned writer, speaker and teacher; author of 35 books; and the world's foremost scholar and historian of fire, about the Pyrocene, about forests and public lands, and about the future of life on this Earth.
