Recovery of the ozone layer due to bans on chemical substances

Today I want to talk about the recovery of the ozone layer. 35 years ago the Montreal Protocol was created to remove 96 chemicals that were causing a hole in the ozone layer. To know what we are talking about, the ozone layer is the area of the stratosphere that protects the Earth from ultraviolet rays. Latest reports confirms that the ozone layer is going to be fully recovered in 40 years. This document says that if current policies are still implemented, the ozone layer is expected to fully recover in the Arctic by 2045. Furthermore in 2066 the most damaged area (Antarctica) will recover completely. The scientific evaluation group confirms the positive impact of the Montreal Protocol, where in 2016 other substances such as hydrofluorocarbons were added, which are powerful greenhouse gasses but don't damage the ozone layer as much as chlorofluorocarbons. Personally, I believe that positive news helps us to realize that everything we do for the planet where we live pays off and that we must continue this wayto improve and never give up for a better planet for future generations.
