The UN's panel of experts has found that the Earth's ozone layer is recovering due to decades of efforts to eliminate ozone-damaging chemicals. The ozone layer acts as a shield in the stratosphere, protecting humans and the environment from harmful UV radiation. This progress is a result of international action taken after the discovery of a hole in the ozone layer in 1985, which was linked to the use of chemicals like chlorofluorocarbons in products like aerosol sprays and refrigerants. Great!
