In this episode of Naturally Scott, Scott sits down with John Adams, Deputy Director and COO of Biosphere 2, for a conversation about one of the most ambitious environmental experiments ever attempted.

Often remembered for its early human habitation experiment, Biosphere 2 is far more than a historical curiosity. John explains how the facility continues to operate today as a living laboratory designed to help scientists better understand Biosphere 1 — Earth itself. The discussion explores how large-scale, closed ecological systems allow researchers to study climate processes, water cycles, ecosystem interactions, and the challenges of sustaining life in controlled environments.

Scott and John walk through the origins of Biosphere 2, the lessons learned from its early years, and how its mission has evolved into cutting-edge research that informs conservation, climate science, and even future space exploration. Along the way, John shares insights from his nearly three decades at the facility, reflecting on its growth, its enduring relevance, and why curiosity about complex systems remains central to scientific discovery.

This is a conversation about experimentation, learning from bold ideas, and the continuing effort to better understand the planet we already inhabit.
