We learn from the passage that ...... .

Of the seven continents, Antarctica is the
coldest, highest, driest and windiest. With an
area of some 5.5 million square miles, it
represents one-tenth of the land surface of the
world. As much as 98 percent of Antarctica is
covered by ice, much of it 1.5 miles thick, and
the continent is surrounded by seas filled with
pack ice arid icebergs for most of the year. Yet
far from being a desolate wasteland, it is
suspected that Antarctica might be a treasure
trove of precious metals, minerals and food.
Hundreds of scientists, geologists and
technicians from some 20 countries are
permanently based at 44 different sites around
the continent. However, not everyone is in
favour of the commercial exploitation of
Antarctica, because of the potentially
devastating effect it might have on the
environment.
