It wasn't until the late 1980s that the world finally came to terms with the fact that manmade chemicals were destroying the Earth's ozone layer. By that point the hole had grown at a rapid pace due to the use of chlorofluorocarbons (CFCs), and after decades of trying to get the general public to believe that humans were at fault it seemed like the world was finally willing to listen. The Montreal Protocol was a global promise made in 1989 by industrial countries to sharply curb the use of CFCs, and it looks like the Earth is finally beginning to repair the damage we wrought.
A new study published in Geophysical Research Letters reveals that, despite the fact that mankind hasn't fully eliminated the use of CFCs globally, the dramatic reduction in their production has allowed the ozone layer to begin to recover. That's great news for future generations, but we still have some work to do.
