This has been on our bucket list for some time so we were really excited to visit this world-renowned marvel. Just think, studying our fragile ecosystem processes under controlled conditions to benefit and improve the quality of life for all of us on Earth (Biosphere 1).
The University of Arizona assumed ownership of Biosphere 2 in July 2011. A generous gift from the Philecology Foundation helps fund Biosphere 2 operations and some research projects. Other grants and awards, primarily from the National Science Foundation, also support research activities.
The tour was just fascinating! But we would like to offer a few warnings to keep in mind which are not verbally given at the beginning of the tour; however they are mentioned in their brochure. The changes in temperature along with increasing humidity and heat then decreasing humidity and cold were a shock to some of the visitors more than others. There were actually some who had to leave the tour and/or ask for assistance. There are also many stairs and inclines, and a fairly dark tunnel you need to walk. Truly it was easy. Yet, we were surprised these warnings were not given in advance especially to some of the participants in our group.
I’m not sure how we would have felt being “sealed in” for a period of two years…but thank goodness there were people who were willing to do this. All in all we would say go and see this wonder.
