The Ozone Layer

Can the ozone hole be healed?

Yes. While the latest figures represent an increase in the ozone hole’s size over previous years, there is some good news: compared to the 1980s, the hole is expanding more slowly. If we continue to reduce pollutants, the expansion may eventually stop and be reversed. Scientists believe that, if this happens, it will take about 50 years for ozone levels to return to natural levels.
