The World Meteorological Organization has cause for joy as the ozone hole over Antarctica decreases.
At present the size is as close to the size of what the ozone hole was in 2007, whilst in 2006 and 2008 it was greater. Scientists believe that the ozone layer will be closed completely around in 2075.
The ozone hole over the 80 years of the last century has been open but not throughout the year. It begins to form in August yet by the end of September it has already reached maximum size and has disappeared by the middle of December.
The ozone layer shields the Earth from harmful ultraviolet solar Rays. These rays can cause burns, eye damage and skin cancer.
This year, its area is expected to shrink to 25 million sq km, with 2 million less than last year, reported the press agency from France.
