Random Earth Systems Fact

Biosphere 2 is a scientific research center in Oracle, Arizona. It is an artificial, closed ecological system - the largest of its kind ever created. Originally its purpose was to show the possibility of such a system to support life in outer space. The biosphere was only used twice because it ran into problems related to food and oxygen, management issues, and fights among the resident scientists. (Earth Systems > Biosphere )
