In this episode of “Stuff You Should Know,” the hosts discuss the Biosphere 2 experiment, a unique endeavor that aimed to replicate Earth and gather scientific data. They explore the origins of the project, the challenges faced by the participants, and the controversies surrounding its success. Join them as they delve into the fascinating world of Biosphere 2 and its impact on environmentalism.
The Biosphere 2 project was born out of the Synergians’ desire to build a self-sustaining habitat for studying Earth’s ecosystems. Led by John Allen, a charismatic genius influenced by Buckminster Fuller, the group incorporated ideas of synergy and the geodesic dome into the project’s design. They embarked on a journey to create a unique and futuristic structure that would replicate Earth.
The Biosphereians, as the participants were called, sealed themselves off in the Biosphere 2 for a two-year mission. They had to rely on what they could grow, facing challenges such as limited food variety and high CO2 levels. The experiment encountered design flaws and unintended consequences, including the desert turning into scrub land and the ocean reef being choked with algae. Despite these challenges, the Biosphereians persevered in their quest to study Earth’s ecosystem in a controlled environment.
Biosphere 2 garnered both excitement and criticism. The project faced controversies for not disclosing the use of a CO2 scrubber and bringing in supplies from the outside. Initially praised as a groundbreaking endeavor, it later received backlash, with Time Magazine labeling it as one of the worst ideas of the 20th century. However, Biosphere 2 also led to significant scientific discoveries, such as a low-tech wastewater system and insights into the impact of ocean acidification on coral reefs.
The Biosphere 2 experiment, while facing challenges and controversies, remains a fascinating chapter in the history of environmentalism. It showcased the ambition and determination of the Synergians and their quest to understand and preserve Earth’s ecosystems. Despite its shortcomings, Biosphere 2 contributed to scientific knowledge and reinvigorated humanity’s love for our planet.
