We've crossed another item off of our Arizona To Do list! This past Sunday, we toured the ecological research facility, Biosphere 2, in Oracle, AZ.
Biosphere 2 is a bit of a controversy amongst Arizonans. Many believe it was a financial failure and waste, while others praise it as a great scientific project. I won't delve into either of those, though the introductory video to the tour does skim over it. I will say that despite my husband and I both being individuals who are very critical of finance/economics, we went in to the tour with open minds and found it to be very interesting from a scientific perspective and a financial perspective.
There were 2 "missions" at the Biosphere: the 1st lasted 2 years, the 2nd ended prematurely. The crew participating in the missions weren't allowed to leave and were supposed to be entirely self sufficient using the agriculture they managed.
Outside of the air chamber.
This tour was a little over an hour and does require a bit of walking through different temperature areas. Overall we found it very interesting. Piece of information that stood out the most: The only other known biosphere is Earth, Biosphere 1.
