About this episode

The episode discusses the challenges faced by Biosphere 2, a closed ecosystem experiment, including an oxygen crisis and its implications on trust and success.

Biosphere 2 was meant to be a closed ecosystem proving humans could survive under glass, until an oxygen crisis forced secret fixes and triggered a spectacular public meltdown over trust, control, and what “success” even means.
