Ozone Layer Shows Signs of Recovery, Scientists Claim

I was browsing the web-site of the "Environmental News Network" and I spotted a very interesting article (Patricia Reaney, Reuters). I quote a small part of it and I appose the link for further reading.

"The ozone layer is showing signs of recovering, thanks to a drop in ozone-depleting chemicals, but it is unlikely to stabilise at pre-1980 levels, researchers said on Wednesday. Depletion of the earth's protective ozone layer is caused by the chemical action of chlorine and bromine released by man-made chlorofluorocarbons (CFCs), which are used in aerosol sprays and cooling equipment [...] They found that ozone levels have stabilised or increased slightly in the past 10 years. But full recovery is still decades away."
