We drove about 40 miles north of downtown Tucson on State Highway 77 near Oracle to get to Biosphere 2. This is a 3.15-acre (12,700 m2) structure originally built to be a man-made, materially-closed ecological system in Oracle, Arizona by Space Biosphere Ventures - a project costing somewhere over 200 million dollars...the entrance fee though is about $20 but sometimes, you can find clippings that give you a significant discount. I think we found one through the Tucson magazine which gave us $5 off.
The facility was used to explore the complex web of interactions within life systems in a structure that included five areas based on natural biomes and an agricultural area and human living/working space to study the interactions between humans, farming and technologies with the rest of nature. So, inside you do see the Amazon Raining Forest, the mangroves of Florida and then even the desert (which was already outside the complex anyways).
But before this place used to be airtight and there people shutr in for months in the eraly 1990's (1994 being the latest) - but now the complex is exposed to air.Biospehere scientists explored the possible use of closed biospheres in space colonization, and allowed the study and manipulation of a biosphere without harming Earth's.

BIOSPHERE 2 CENTERBiosphere 2 covers 3.15 acres, it is 91 feet tall at it's highest point. It is sealed off from Earth below by a 500-ton welded stainless steel liner. The water, air and soil are constantly monitored. The 25 foot ocean holds a million gallons of salt water.
Biosphere 2 contains five biomes -
a rainforest, desert, savanna, marsh and ocean. (A biome is a self-sustaining community of living organisms.) Biosphere 2 was created to better understand Biosphere 1 - Earth. It is open for public tours now and features exhibits such as the Climate change and Life on Earth exhibition.
