Just about every person who participated in the Biosphere 2 experiment -- and subsequently the new documentary about it, called Spaceship Earth -- talks about the scientific goals of their undertaking. As noble as these scientific aspirations were for the project, it’s pretty clear that they were secondary to more emotional and psychological interests. One of the eight members who volunteered to live inside an airlock-sealed facility for two years -- they called themselves biospherians -- recalls her first thoughts just after the door to the outside world was shut and locked on day one. She describes turning on the rain in the vegetation section of the biosphere and gaining a sense of peacefulness. She wanted to wash the air, to wash out the impurities of the world she left behind and "begin anew." She soon discovers, as do we, that it's not easy to begin anew when messy interpersonal human dynamics are involved.
