It’s a story that has never been told… until now. Imagine being sealed into a three-acre greenhouse for two years… cut off from the outside world with only seven other people for company… enduring never-ending hunger, severely low levels of oxygen, and extremely difficult relationships. That’s what happened inside Biosphere 2, where crewmembers struggled to survive while keeping their promise that nothing would go in or out – no food, no water, not even air – all in the name of science. For the first time, biospherian Jane Poynter – who lived and loved in the Biosphere – is ready to share what really happened inside the controversial project. She takes readers on a riveting, fast-paced trip through shattered lives, scientific discovery, cults, love, fears of insanity, and inspiring human endurance. The eight biospherians who closed themselves into the Biosphere in 1991 emerged 730 days later… much wiser, thinner, and having done what many had said was impossible.
