Pushing Our Limits-9780816537327

Pushing Our Limits is a fresh examination of Biosphere 2, the world's first man-made mini-world, twenty-five years after its first closure experiment. Author Mark Nelson, one of the eight crew members locked in the enclosure during the 1991-93 experiment, offers a compelling insider's view of the dramatic story behind Biosphere 2. With current concerns of sustainability and protection of our global biosphere, as well as the challenge of learning how to support life in space and on Mars, the largest, longest, and most important experiment in closed ecosystems is more relevant than ever. The book explores Biosphere 2's lessons for changing technology to support and not destroy nature and for reconnecting people to a healthy relationship with nature.
