Hey Earthlings!
We have great news for the planet: The ozone hole at the South Pole is shrinking and has shrunk by 700,000 miles so far.
NASA said the hole reached an average area of ??8.9 million square miles in the time period September 7 to October 13.
Satellite observations indicated that on October 5, the surface reached 10.2 million square miles, but this rate has fallen, giving way to a shrinking ozone hole.
"Over time, steady progress has been made and the hole is shrinking," said Paul Newman, chief of the Earth sciences department at NASA Goddard Space Flight Center.
But the greatest contribution was made by the Montreal Protocol, a treaty established 35 years ago.
This treaty banned the emission of CFC (chlorofluorocarbon) chemicals, harmful to the ozone layer.
Meanwhile, the ozone layer prevents harmful ultraviolet rays from penetrating the planet.
