Chris explains mass extinctions are rare, only five in ~540 million years, and contrasts past causes (asteroids, volcanism, climate and ocean chemistry shifts) with today’s human-driven “death by a thousand cuts,” including habitat loss and fragmentation, invasive species, overexploitation, pollution, and climate change. Chris argues extinction today is often subtle but highlights hope through global conservation efforts, citing northern white rhino embryo work, elephant corridor protection, and many individuals dedicating their lives to saving species. If you enjoy these episodes, you'll love our new Substack. Each week, I dive deeper into the stories behind the podcast, sharing personal experiences from my years in wildlife conservation, reflections on the science, and the remarkable people working to protect our planet.
