Biosphere 2 Project.

Before we start talking about the Biosphere 2 Project, we need to know what does a biosphere is.
A biosphere is the sum of all ecosystems. The biosphere has another name,which is more commonly used, which is planet Earth.

During the 1st year, the crew showed continual hunger, while in the second year; the atmosphere of Biosphere 2 produced more than aton needed for surviving, during this time, the health of all the crew was excellent. After this, they improved the same health levels gained inside Biosphere 2.
