Biosphere 2 is for sale.

TUCSON, Arizona (AP) -- The company that owns Biosphere 2 Center, 3.1 glass-enclosed acres designed to simulate the Earth's environment, has put the site up for sale.

The company is also selling 70 other buildings on the center's 140-acre campus 16 miles north of Tucson, said Christopher Bannon, general manager of Decisions Investment Corp. of Fort Worth, Texas.

"We'd love to see the Biosphere 2 used as a research activity, but we know that may not be the end result," he said last week.
