Biosphere 2

The Biosphere 2 was an experiment to determine whether a group of people could live in a fully enclosed environment that would simulate earth (known here as the Biosphere 1). Such a place would be needed if humans were to ever hope to colonize another planet. The Biosphere 2 contained several different of earth's environments such as a rainforest, a desert, a savanna and a tropical ocean with reef. There was no circulation of water, air, soil or animals with the outside. A group of 8 people (4 men and 4 women) lived here for 2 years. A second group lived here for 6 months. Unfortunately the experiment did not work as carbon dioxide built up and oxygen had to be added 3 times in the course of the 2 years. Today, the facility offers tours. The Biosphere 2 is located about 30 miles north of Tucson near Oracle, Arizona.
