Irrationals in Hope of the Impossible: The Origins of Biosphere 2 at Synergia Ranch in the Seventies

Mark Nelson's memoir documents the origins of Biosphere 2 at Synergia Ranch in the 1970s and the ecological community behind one of the 20th century's most ambitious human experiments. The book presents the Institute of Ecotechnics and its pioneers as people who combined ecological thinking, systems science, practical experimentation, and creative collaboration to imagine a more regenerative relationship between humans and the living biosphere. The supplied endorsements describe the work as both a historical record and an energizing guide for environmentally integrated futures, including regenerative farming and alternatives to systems damaging Earth's life support networks. At 352 pages, the book emphasizes firsthand experience, optimism, audacious projects, and the continuing relevance of Biosphere 2's origins.
