A report by the United Nations has revealed that the depleted ozone layer will recover in 43 years. The Earth’s ozone layer, which protects out earth from UV radiations, is recovering at a rate that will close the hole above Antarctica in 43 years, a UN study conducted every four years mentioned.

Montreal Protocol 1989
After the shocking depletion in the ozone layer in the 1980s, countries came together to sign an international treaty to eliminate 99% of ozone-depleting chemicals that damage the stratospheric ozone layer. After 35 years of combined effort, the ozone layer has partially recovered, and is expected to fully in the next 43 years.
Ozone Eating Chemicals On Decline
According to the study, bromine levels have declined by 14.5 percent in the last 24 years, while chlorine levels have decreased by 11.5 percent since they reached new heights in 1993. But the challenge is far from over as the world is yet to replace fossil fuels.
