Because of pollution, the Earth's ozone layer has suffered a lot. That's bad news for everyone, since the fragile gas layer protects our planet and shields us from the sun's harmful ultraviolet rays. Fortunately, climate change experts believe that the ozone layer will recover to '80s status by the time we hit 2040, according to a 2022 report from the World Meteorological Organization. The recovery is thanks in large part to the Montreal Protocol of 1987, which put a global ban on the use of one of the main culprits for the damage: chlorofluorocarbons (CFOs). Previously, CFOs had been common in refrigerators, aerosol cans, and dry-cleaning chemicals.
Thanks to the Montreal Protocol of 1987, we've banned those harmful CFOs that used to be everywhere. Now, experts say the ozone layer might be back to its '80s glory by 2040. 
Let's keep up the good work and protect our planet!
