BIOSPHERE 2: The Human Experiment by John Allen (Penguin: $16.95, illustrated). This spring, eight human volunteers will enter Biosphere 2, a 3.15-acre building designed to function as a prototypal space station or extraterrestrial colony. They hope to spend two years in this sealed, self-sustaining environment that includes a miniature rain forest, desert, savannah, ocean and marshes, inhabited by 3,800 other animals and plants. Allen, one of the key participants in the project, offers his view of the history and goals of this potentially fascinating $60-million ecological/biological/technological experiment.
