Paragraph 1
Scientists have discovered what they believe to be the cleanest
on Earth. Researchers from Colorado State University and the Australian Bureau of Meteorology conducted
on the
of the air above Antarctica. They found a
over the Southern Ocean, between the south of Australia and Antarctica, that was "unaffected" by human
. The scientists said the area they researched formed the
in the lower clouds. The
of the air showed that it was totally
from "anthropogenic aerosols". These are pollutants or particles derived from
activity, or dust from other continents. The scientists called this pollution-free area, "truly
".
