Question

Quizplus · Accepted Answer

The use of CFCs has been significantly reduced since the signing of the Montreal Protocol in 1987, which regulated the production and consumption of ozone-depleting substances. As a result, the ozone layer has been slowly recovering, and it is expected to reach pre-1980 levels by 2070. While there are still some regions where ozone depletion occurs, the complete destruction of the ozone layer is no longer a threat.
