Why no human beings live in Antarctica?

Answer 1

There is no native or permanent population on the continent: it's too cold and there is no food chain. As well, there are no countries on the continent.

Under the Antarctic Treaty, all land on planet earth south of 60 degrees S is preserved for science. This means that governments that support scientific research on Antarctica hire and support scientists and workers on the continent, who study the health of planet earth. All workers and scientists live there on a temporary basis.

Answer 2

Humans do live in Antarctica, but none permanently.
