In 1991 a group of countercultural visionaries built an enormous replica of earth’s ecosystem called Biosphere 2. When eight “biospherians” lived sealed inside, they faced ecological calamities and cult accusations. Their epic adventure is a cautionary tale but also a testament to the power of small groups reimagining the world.
