In the late 1980s, a biosphere was built in Oracle, Arizona. This artificial, closed ecological system, Biosphere 2, was built to mimic the conditions of our planet and its capacity to maintain life through meticulously balanced ecosystems. It sat on 3.14 acres of land and remains the largest closed system ever created.

For two years, four men and four women had to grow their own food and live off their own recycled water and air that was sustained by their own small rainforest, savannah, ocean and farm. Careful planning had to go into its engineering because life on earth is a vast web of interconnected and interdependent elements that affect each other’s existence and survival. Everything is connected.

Biosphere 2 was largely successful, but there were significant complications; the most serious being an unanticipated loss of oxygen. Over seven tonnes of oxygen were lost within the biosphere.

CO2 that was meant to be absorbed by the plant life and converted to oxygen was instead unexpectedly absorbed into the concrete, causing severe oxygen depletion. This affected the blood chemistry of the inhabitants. They began waking at night gasping for air, suffering from sleep apnea. This, in turn, impacted negatively on their mood, creativity, problem-solving skills and interpersonal behaviour.
