At a time when species across the country face mounting pressures, the Endangered Species Act remains one of the most powerful—and contested—tools we have to protect them. In this installment of our “Explained” series, host Sebastian Duque Rios is joined by three experts whose careers span law, policy, and conservation science: Patrick Parenteau (Vermont Law & Graduate School), Jake Li (Defenders of Wildlife), and David Wilcove (Princeton University).

Together, they break down how the ESA works, why it was created, and the real-world threats species face today. The conversation explores key provisions of the Act—from listing decisions and critical habitat designations to Section 7 consultations, recovery planning, and the role of private landowners. The guests also discuss how funding shortfalls, political pressures, and recent proposals could reshape endangered species protection in the years ahead.

Whether you’re new to the ESA or looking for a richer understanding of its legal, scientific, and practical dimensions, this episode offers a clear and candid look at the challenges and opportunities facing one of the nation’s cornerstone conservation laws.
