Biosphere: Self Sustaining Environment
People who fly in space have to eat food that they bring from earth. In the future, these people will grow their own food.
Scientists are getting ready for the future by making a biosphere. In Arizona, scientists are building one. In 1989, eight people will begin living inside the biosphere. They will be sealed off from the outside world. They will grow their own food.
A scientist said, on another planet we will need some kind of life system. This will be a test to see if it can be done.
The project is called Biosphere Two. Many different areas will be put in the biosphere. It will copy the oceans, the tropics, and a rain forest. A small desert and a tiny swamp will be put in. A greenhouse will help them grow food.
They will try to grow all of the food they need. If they can do this, then it could be done on another planet that does not have any plants growing on it.
The idea has been tried already. On a desk in an office, two tiny shrimps have lived two years in a sealed globe.
