Biosphere 2 Center

Biosphere 2 Center is the handiwork of eight scientists to see how humans would cope in a sealed off environment. After the completion of the project the Biosphere remains operational and can be toured. Located just outside of Tucson it features a tropical rain forest, desert gardens, ocean, savanna, marsh, thorn scrub and a comprehensive agricultural area. Tours take a couple of hours and the visitor center displays a film explaining the project. Situated on 250 acres, amidst the beautiful Sonoran Desert, Biosphere 2 Center is one of the largest living laboratories of the world.
