According to a United Nations report, the Earth's ozone layer is slowly recovering. The report found that the hole in the ozone layer above Antarctica is expected to fully close over the next few decades.
The healing process has been attributed to the global ban on ozone-depleting substances, which was established in 1987 by the Montreal Protocol.
The report also noted that the Earth's atmosphere has not yet reached its pre-industrial ozone levels, and continuation of policy is crucial for fully recovering of ozone layer . The recovery of the ozone layer is crucial for protecting life on Earth from harmful ultraviolet radiation.
