Ozone layer will be completely healed by 2060s: UN study
A United Nations' study has revealed that the Ozone layer, which shields the Earth against cancer-causing solar rays, will be completely healed by 2060s. The hole above the Antarctic is healing at a rate of 1-3% a year, the study further revealed. The study was a four-yearly review of the Montreal Protocol which banned man-made gases damaging the Ozone layer.
