All about Biosphere 2

In this video you can learn all about Biosphere. What is Biosphere 2 you may ask well you can find out exactly what in this video:

Chronology of Biosphere 2

Biosphere 2 was actually only ever used twice for its original intended purposes as a closed-system experiment: once from 1991 to 1993, and the second time from March to September 1994. Both attempts, ran into problems with low amounts of food and oxygen, many animal and plant species dying off, arguing among the resident scientists and management issues. In June 1994, in the middle of the second experiment, Space Biosphere Ventures was dissolved, and the structure was left in limbo. It was then purchased in 1995 by Columbia University, who used it to run experiments until 2005. At that point in time it looked in danger of being demolished to make way for housing and retail stores, but ended up being taken over for research by the University of Arizona in 2007; the University of Arizona then granted full ownership of the structure in 2011.

Biosphere 2: 25 years later

Now 25 years after 8 Biospherians took up residence in Biosphere 2 for 2 years it is even clearer how innovative and imaginative the concept behind Biosphere 2 was and still is. Biosphere 2 is a site to test greenhouse technology and a place where one can imagine and investigate some of the extraordinary challenges of space exploration.

If you’re looking for more information here is a News Article I found on how Biosphere 2 is doing after 25 years. this article was written by Joaquin Ruiz the dean at University of Arizona College of Science and was published on the 27th of January 2016 at 12:00pm.



Was Biosphere 2 A success or a failure?

In my opinion although the eight biospherians were not able to live in Biosphere 2 for more than two years due to technological failures, I feel that Biosphere was still a success. Now that we have found out the problem we can work towards fixing it and making other things more efficient. Some ways that this technology could help us is that in major droughts or floods the artificial biosphere stays in the same reliable state. Some improvements that were made were to do with mostly oxygen. Such as concrete being sealed to prevent uptake of carbon dioxide. In the future when artificial biospheres have advances their technologies they could help us to be able to inhabit otherwise uninhabitable places. This could help with overpopulation. If artificial biospheres do become something important to society (e.g with overpopulation) this could really help us to survive without being effected by environmental difficulties (e.g flooding or droughts). But they might become something that only rich people can afford to inhabit which could cause major uproars. Although artificial biospheres can help us with flooding and droughts they could also have major effects on the environment such as sucking up lots of valuable resources to be built and kept maintained. In the end it’s all about trail and error.
