Scientists who study the health of planet earth in Antarctica are not chartered with the challenge to 'help sustain life' in Antarctica.
There is no animal life to sustain and 98% of the continent is covered by an ice sheet.
In a way, none of them, but Antarctica does have scientists there and they're living people
No animals live in Antarctica. Humans go to Antarctica as scientists, in support of science or as tourists. There is no native population there. Why? It's too cold in Antarctica to support life.
Since new discoveries have revealed that life in Antarctica is mysterious -- Lake Vostok contains life and has been buried under the ice for millions of years -- it is unclear what percentage of the continent can sustain (microbial) life. Visible plants, however, are only found in the Antarctic Peninsula, a small portion of the continent. Given these unknowns, a percentage would only be a guess.
The absorption of ultraviolet radiation by the ozone layer help to sustain life because it helps to protect living things from damage of solar radiation.
Scientists and workers in support of science live in Antarctica temporarily: there is non native population there -- it is too cold to support life.
Air helps us breathe. Air also helps life sustain and grow. It makes Earth the only known planet to sustain life.
It is too cold and there is not enough vegetation to sustain a herd of giraffe's.
you gota ask someone else
Aside from the research scientists who spend months in the frigid environment, the only Antarctica Dwellers are penguins and other birds, and the marine life in the surrounding oceans.
You need water to live and other planets don't have water
So far, earth is the only planet known to support life, but many scientists thing that life probably exists on other planets.
No Jupiter doesn't sustain life.
