The ozone hole, once the most feared environmental hazard to mankind, is expected to disappear completely in most parts of the world within the next few decades, thanks to decisive action by many governments to phase out the substances that produced it.
It is expected that the ozone layer will recover in 4 decades.
The regeneration of Earth’s invisible shield is an inspiring example of how the world can come together to tackle global challenges like the climate crisis.

This is the opinion of specialists from the United Nations (UN), who emphasize that the depletion of the ozone layer, which put people’s exposure to the sun’s harmful ultraviolet rays at risk, is on the way to a complete recovery for 2040 in much of the world.
Since the alarm that was launched in the eighties of the last century, the ozone layer has improved constantly as a result of the Montreal Protocol of 1989, an international agreement that helped to eliminate 99% of the chemical products that affected it, such as chlorofluorocarbons (CFCs), which were used as solvents and refrigerants.
The prohibition of 99% of chemicals harmful to the environment has promoted that the hole in the ozone layer is returning to normal
According to a report published by NatGeo, Antarctica could recover its natural ozone cover by 2066. The Arctic, a few decades earlier, in 2045. The rest of the world by 2040. This is so, because the deterioration has been progressively repaired, specialists explain.
