Biosphere 2

Today our studies took us into the Catalina foothills where the Biosphere 2 project still stands. In the late 80’s and early 90’s this was an experimental ecosystem. For two years, 8 “biospherians” lived in this sealed environment, testing whether it could be self-sustaining. This is a huge and impressive structure made of steel and glass and an intricate underground network which regulates temperature, humidity, winds, power, and rain. There are very distinct ecosystems within the biosphere: savannah, ocean, desert, and rainforest. At the onset, there were 3800 species of plants and animals living in the structure. It served as a farm, living quarters, and research center.

P.S. Biosphere 1 is the earth itself.

This is the basement of the biosphere. It’s several acres of pipes, power conduits, etc.

We celebrated Richard’s birthday today. Guess what? The gift we gave him was THE RIGHT MODEL!! I’m so relieved.
