What is wilderness when seven billion people share the planet and nowhere remains truly untouched? Author and journalist Cal Flyn discusses her book The Savage Landscape with EconTalk host Russ Roberts, weaving together journeys to some of Earth's most remote places, including a live volcanic eruption in Iceland she hiked toward despite the danger. Flyn rejects the myth of pristine, unpeopled wilderness, revealing that the wildest-looking landscapes have been shaped by humans for centuries. She explores spiritual quests at Mount Sinai, the return of predators to Europe, the uncomfortable economics of trophy hunting, and why we secretly crave discomfort in an age of endless comfort.
