World’s Biosphere 2

Title:World’s Biosphere 2
Location:Oracle, Ariz.
Description:It turned out that probably at that exact moment the Biosphere was being sold for $50 million to a real estate development company, which planned to build a resort hotel and luxury homes on the surrounding desert land. The University of Arizona was given the three-acre terrarium as a minicampus for its ecology program. This ended its brief, four-year stint as a roadside attraction.
