Due to pollution, Earth's ozone layer has been severely affected.

This is bad news for everyone because the thin layer of gas protects our planet and shields us from the sun's harmful ultraviolet rays. When the fragile ozone layer is depleted, the sun's ultraviolet rays can reach the earth, making people more susceptible to skin cancer, cataracts, and other diseases. Fortunately, climate change experts believe the ozone layer will completely heal within 50 years, according to a 2018 United Nations report.


The Main culprit

Scientists discovered the great harm of diapers in the 1980s and identified chlorofluorocarbons, or CFCs, as the main culprit. CFCs were once common in refrigerators, aerosols, and dry cleaning chemicals, but were banned globally under the 1987 Montreal Protocol.


As reported by the United Nations Environment Program, the World Meteorological Organization, the European Commission, and others, the reduction in the number of CFCs in our atmosphere as a result of these measures is now which means the ozone layer is expected to fully recover in the 2060s.


The Awaited Good News

A 2018 study found that part of the ozone layer has recovered at a rate of 1% to 3% per decade since 2000. At this rate, Northern Hemisphere and mid-latitude ozone should fully recover over the next decade. The ozone layer recovers slowly. At this rate, ozone in the northern hemisphere and mid-latitudes is expected to fully recover within the next 10 years. While the southern hemisphere will recover in the 2050s and the polar regions in the 2060s. Experts estimate that 2 million cases of skin cancer worldwide could be prevented each year by 2030.


In the parts of the stratosphere where most of the ozone is found, the authors say, the stratosphere has been recovering at a rate of 1 to 3 per cent per decade since 2000. At the rate of recovery reported by the United Nations, ozone in the northern hemisphere and mid-latitudes is predicted to fully recover by the 2030s, followed by the southern hemisphere by the 2050s and the polar regions in 2060.
