Mark Nelson, one of the eight crew members locked in Biosphere 2 during its first closure experiment, 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.

Industry Reviews

A fascinating account of the largest, longest and most important experiment in closed ecosystems ever conducted."" - Chris McKay, Senior Scientist, NASA

""In the early 1990s eight people sealed themselves into a self-contained ecosystem in the Arizona desert. Two decades later, Mark Nelson reflects on his experience inside Biosphere 2 as a microcosm of our global challenges with water, food, and energy. Only with a deep understanding of the biosphere's workings, Nelson argues, can humanity craft an ethical relationship with the planet Earth."" - Melissa L. Sevigny, author of Under Desert Skies: How Tucson Mapped the Way to the Moon and Planets
