Spaceship Earth is the true, stranger-than-fiction adventure of eight visionaries who in 1991 spent two years quarantined inside of a self-engineered biodome called BIOSPHERE 2. The experiment was a worldwide phenomenon, chronicling daily existence in the face of life-threatening ecological disaster and growing criticism that it was nothing more than a cult. The bizarre story is both a cautionary tale and a hopeful lesson of how a small group of dreamers could potentially reimagine a new world.
