Today's episode is produced in partnership with the Global Challenges Foundation. The Foundation is dedicated to raising awareness of global catastrophic risks and strengthening global governance to address them. Global Challenges Foundation's 2026 Global Catastrophic Risks report outlines five of the biggest risks facing humanity today, including ecological collapse, the topic of this episode. You can find this report at globalchallenges.org/gcr-2026.

Two of the authors of the chapter on ecological collapse are my guests today. David Obura is the director of CORDIO East Africa, a nonprofit research organization based in Kenya, and chair of the Intergovernmental Platform on Biodiversity and Ecosystem Services. Eva Mineur is head of climate and sustainability at Global Challenges Foundation.

We kick off by discussing what we mean by ecological collapse and examining examples of this phenomenon already underway around the world, before turning to a longer conversation about how to strengthen international cooperation and global governance to prevent ecological collapse—and the catastrophe it would entail.
