(CNN)The hole in the Earth's ozone layer is expected to fully heal within 50 years, climate change experts predict in a new UN report. A fragile shield of gas around the planet, the ozone layer protects animal and plant life from the powerful ultraviolet (UV) rays of the sun. Scientists discovered huge damage to the layer in the 1980s and identified chlorofluorocarbons, or CFCs, as the main culprit. At the recovery rates projected by the UN report, the northern hemisphere and mid-latitude ozone is scheduled to heal completely by the 2030s, followed by the southern hemisphere in the 2050s and polar regions by 2060.
