"Long before Stephen Bannon was CEO of Donald Trump's presidential campaign, he held a much different job - as the acting director of Biosphere 2, a $200 million scientific research facility in the mountains outside Tucson, Arizona. ... Bannon left Biosphere 2 after two years, and the project was taken over by Columbia University. (It is currently part of the University of Arizona.) But his departure was marred, as the Tucson Citizen reported at the time, by a civil lawsuit filed against Space Biosphere Ventures by the former crew members who had broken in."
"Archival reports from 1993 found in the Star-Telegram archives show that Bannon was hired to take over the project at a point where it losing $12-15 million a year. Bannon was a former Goldman Sachs investment banker who ran a firm based in Los Angeles and New York that specialized in media and entertainment investments. .. Bannon's actions soon ended up as part of a civil suit filed by some of the original Biospherians against the new guard. In court, he admitted speaking angry words that echo some more recent accusations against him."

"Biosphere 2 was only used twice for its original intended purposes as a closed-system experiment: once from 1991 to 1993, and the second time from March to September 1994. Both attempts, though heavily publicized, ran into problems including low amounts of food and oxygen, die-offs of many animal and plant species, squabbling among the resident scientists and management issues."
