Summer reads – How we made the wilderness w/Cal Flyn

What if the places we think of as empty and unmarred are anything but? What if wilderness is as much an idea as a place? A conversation with Cal Flyn, who, in her new book, travels to some of the world's most remote, awe-inspiring places to trace the changing meaning of wilderness, and to explore how one of conservation's most cherished ideals has come at a human cost.
