On Sept. 26, 1991, eight scientists sealed themselves into the compound for a two-yr keep.
Within 5 months the atmospheric oxygen content material of Biosphere II dropped from 21 p.c to 14 p.c, while carbon-dioxide and nitrous-oxide levels rose dangerously regardless of a classy recycling system. Oxygen needed to be pumped in to sustain Biosphere II. The scientists managed to stay in Biosphere II the complete two years; nonetheless the opposite residents were not so fortunate. By the time the seal was damaged, 19 of 25 vertebrate species were extinct along with all the pollinators. The populations of “weedier” species like vines, cockroaches,
