DOCUMENTARY
This is Biosphere 2.
Scientists built this place in the 1980s. They wanted to study the earth’s
environment, and learn the best way to build a similar place on the moon and on
the planet Mars.
This is a model of Biosphere 2. It has different kinds of places, of
biomes. There’s an ocean, a rain forest, a grassland, a marsh, a desert, a
farmland, and a human habitat.
Today, scientists use Biosphere 2 to study many different things, but not
how to build a place to live in on the moon or on Mars.

how to build a place o live in on the moon or on Mars. One important thing they

And they want to learn how this affects the earth and everything that lives
on the earth.
Scientists say that in the future, people will have o make difficult
choices about how they live on our planet.
