What is Sustainability

Book Cover: What is Sustainability

Twelve years ago this September, eight men and women said goodbye to wellwishers and walked into Bios- phere II, a 3.1-acre airtight greenhouse in the Arizona desert. The door was sealed behind the “bionauts,” a team of specialists right out of Mission: Impossible: a systems engineer, a physician, two biologists, agricul- tural scientists, a computer systems expert. They planned to remain under glass together for two years, proving that humans could design, construct, and live in a self- sufficient ecosystem.
