A look at the group of people who built the Biosphere 2, a giant replica of the earth's ecosystem, in 1991.

The true, stranger-than-fiction, adventure of eight visionaries who in 1991 spent two years quarantined inside of a self-engineered replica of Earth's ecosystem called Biosphere 2. The experiment was a worldwide phenomenon, chronicling daily existence in the face of life threatening ecological disaster and a 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 can potentially re-imagine a new world.
