One of the eight crew members locked in Biosphere 2 during its first closure experiment, Mark Nelson discusses his new book Pushing Our Limits, published by the University of Arizona Press, and offers a compelling insider’s view of the dramatic story behind the mini-world. Nelson clears up common misconceptions about the 1991–1993 closure experiment as he presents the goals and results of the experiment and the implications of the project for today’s global environmental challenges and for reconnecting people to a healthy relationship with nature.
