Prominent research ecologist Dr. Paul Hessburg began his career decades ago as a U.S. Forest Service entomologist, studying the insects that kill trees on the grandest scale. Over the years, Hessburg broadened his scope, delving deeper into the greatest force for ecological change on Earth: fire and the age we live now in, the Age of Megafire, or the Pyrocene. Listen to this fascinating deep dive into how we got here and where we must go – if we hope to survive. To get the absolute most out of this conversation, revisit BHA Podcast & Blast Episode 66, our interview with fire historian Dr. Stephen J. Pyne, who coined the term “the Pyrocene.”
