Life in Biosphere 2

Living for two years in a completely sealed, three-acre habitat exposed the deep interconnections between humans and the environment. A four-month effort to make a single pizza and the mysterious loss of seven tons of oxygen highlighted how delicate and complex closed ecosystems can be. The experience sparked a profound awareness of personal impact on the planet and the importance of every small action. Intimate encounters with scarcity and abundance reshaped the understanding of what it takes to sustain life—on Earth and beyond.
