September 1991 Biosphere 2 (8) crewmembers enter the sealed habitat.
By Winter 1991 carbon dioxide levels are unacceptable. Oxygen had to
be added and Biosphere 2 was no longer a sealed unit.
By Septemeber 1993 the crew exited hungary and depressed.
Many of the crew claimed victory.
The general purpose of the Habitat was to survive with
own-grown food, plants and while some success was measured
the project overall was less than successful.
