Remember the Arizona Biosphere? What happened?

Author: Gen Z - Andy Velazquez from Plano, Illinois is currently in his third year at the University of Wisconsin Milwaukee School of Architecture.

Biosphere 2, the airtight, three-acre, $150-million futuristic mini-world facility near the aptly named town of Oracle, Arizona was both a success and a failure. The structure looks like a futuristic spaceship that just crashed in the middle of the desert. Especially at the time it was created, it must have been a crazy looking phenomenon to the average person.

This mini replica of Earth was designed to be a true self-sustaining structure that could sustain all aspects of life. The debate over whether it was a success, or a failure is still ongoing today. Some people argue that because of the errors that occurred, as well as the inability to be completely self-sustaining, it was a failure and a waste of millions of dollars. However, there are others who claim it was a successful experiment that helped scientists better understand Earth’s environment and what necessary steps need to be taken to save the suffering planet. In the eyes of an everyday person, it most likely seemed that Biosphere 2 was a successful experiment and achieved the overarching goal of spreading awareness about Earth’s climate.

Several things went wrong with Biosphere 2 while the scientists were living in it. Recreating the earth and its ecosystems seemed like a near impossible task, especially since the mindset was to make it self-sustainable. Some people from the Nice Try Utopian podcast considered that overall, Biosphere "sucked" and "failed at all its goals". The water systems became polluted with too many nutrients, the level of dinitrogen oxide became too high and most of the animal species went extinct.

There were about 3,000 plant and
