However, balancing all the ecological inputs proved to be a bigger challenge than all those smart scientists could handle.

It was designed to sustain 8 scientists with a self-contained ecosystem. That's $25 million per capita. The ecosystems of Biosphere 1 (planet earth) support over 7 billion people. By that math, the value of ecosystem services provided by planet earth would be worth $25 million times 7 billion, or $175 quadrillion. We should take good care of such a valuable asset.   PS - The 8 scientists were driven out of Biosphere2 after about 2 years by rising CO2. Fortunately, they were saved by Biosphere1.

These are static images but give you a good idea about how it will eventually look once it’s live.  It will also show what functionality it will have. Website Design!
