Biosphere 2 rises from southern Arizona's high desert like a bizarre hybrid spaceship and greenhouse. Packed with more than 3,800 carefully selected plant, animal and insect species, this mega-terrarium is one of the world's most biodiverse, lush, and artificial wildernesses. The story of this grand eco-utopian adventure (and misadventure) has become a parable about the relationship between humans and nature in postmodern America.
