Biosphere 2 sees new life as cutting-edge research facility
Biosphere 2 started with eight scientists and a very ambitious experiment. Now, almost 35 years later, it's still being used for cutting-edge research.

Oracle, Arizona – What began as a bold, some might say audacious, experiment in self-sustaining living is now thriving as a state-of-the-art research facility. Biosphere 2, initially envisioned as a prototype for future space colonization, continues to push the boundaries of scientific understanding almost 35 years after its first inhabitants sealed themselves inside its glass and steel walls.
Originally, the mission was to see if eight “Biospherians” could survive for two years in a completely sealed environment, relying solely on the resources within the 3.14-acre structure. The experiment, while groundbreaking, faced numerous challenges, including fluctuating oxygen levels and unexpected species die-offs. Despite these setbacks, the valuable data and lessons learned from that initial phase have paved the way for its current role as a world-renowned research hub.
Today, Biosphere 2, owned and operated by the University of Arizona, is a far cry from a closed ecosystem. Instead, it serves as a unique and highly controlled environment for studying a wide range of pressing environmental issues. Researchers are using its distinct biomes – including a rainforest, ocean, desert, and savanna – to investigate the effects of climate change, water scarcity, and other critical challenges facing our planet.
One of the significant advantages of Biosphere 2 is the ability to manipulate and monitor environmental factors in a way that's impossible in the natural world. Scientists can precisely control temperature, rainfall, and carbon dioxide levels to observe their impact on ecosystems and organisms. This level of control allows for rigorous testing of hypotheses and the development of potential solutions to environmental problems.
Biosphere 2’s legacy extends beyond its scientific contributions. It serves as an educational platform, inspiring future generations of scientists and environmental stewards. Public tours and educational programs provide visitors with a firsthand look at the complex interplay between living organisms and their environment, fostering a greater appreciation for the delicate balance of our planet. While the original experiment may have had its ups and downs, Biosphere 2's continued evolution as a cutting-edge research facility demonstrates its enduring value in understanding and addressing the environmental challenges of the 21st century.
