The ozone layer, which protects us from ultraviolet light, looks to be successfully healing after gaping holes were discovered in the 1980s.
The Northern Hemisphere could be fully fixed by the 2030s and Antarctica by the 2060s.
A new United Nations report says it's an example of what global agreements can achieve.
The ozone layer had been damaged by man-made chemicals called chlorofluorocarbons (CFCs).
At its worst in the late 1990s, about 10% of the upper ozone layer was depleted.
But since 2000, it has begun to increase again by about 3% per decade, according to the UN report.
Great to see .
Of course, 2060 is still some way off, and there's every chance that we'll find some other way to screw it up before then, but this is still encouraging!
