Summary
Chris reframes migration as a planet-connecting system that moves energy and nutrients and keeps ecosystems in sync—now facing a growing “migration collapse,” where patterns break down before species disappear. He explores three failure modes: disrupted timing from climate change, broken routes from human barriers, and energetic failure when animals can’t find enough food. Through monarch butterflies, gray whales, and salmon, he shows a spectrum from fragile resilience to systems already failing. The episode closes with a hopeful message: when pressure is reduced, nature can respond—and protecting migration corridors is key.
