Biosphere 2

Biosphere 2 is a research facility located in Oracle, Arizona, where scientists explore the workings of Earth's complex systems so that we can all live more sustainably. Built between 1987 and 1991 the facility was built as an enclosed system to demonstrate the viability of closed ecological systems to support and maintain human life, which means scientists can observe how different structures and materials interact together without influence from outside systems.  Today the facility continues to host research as well as tours to the public that are given multiple times a day.  Through the tour you will walk through the 7 different biomes of planet earth in a single trip.
