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
Scientists are measuring the ice cap and looking at the what the atmosphere was like a long time ago.
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.
Scientists working in Antarctica study the health of planet earth.
Scientists and workers in support of science live in Antarctica temporarily: there is non native population there -- it is too cold to support life.
Scientists do not live in houses in Antarctica. Scientists sleep in dorms and eat in dining halls at the research station, and may spent their non-working time in field tents away from the research station.
Antarctica is used by scientists by way of their governments.
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.
Scientists live in a heated tent
You'll find both there. Some scientists ski, and there is some cross-country skiing in Antarctica. Some cross-country skiers in Antarctica are not scientists.
Yes.
