Jane Poynter conta a história de viver dois anos e 20 minutos na Biosfera 2 — uma experiência que a levou a explorar como podemos sustentar a vida num dos ambientes mais difíceis.

Esta é a primeira palestra TED recuperada de uma palestra TEDx, organizada de forma independente, realizada na Universidade da Califórnia do Sul.

Viver na Biosfera 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.
