It could be the first good news for the environment and for the Earth for many years now. The hole in the ozone layer is an age-old problem that seemed unable to be solved. Recently, however, considering the density, concentration and extent of the ozone area, the picture has improved a lot, probably thanks to the Montreal Protocol signed by an ever-increasing number of nations.
Il document it was introduced almost thirty years ago, and it took care of banning the use of chemicals responsible for the destruction of gas. The ozone hole was discovered in 1985.
The ratification of the protocol has so far taken place in 192 countries and will lead to the total ban on the substances indicated by 2030. Already now, however, we have obtained a great result, according to what researchers from MIT and the University of Leeds say: the thinning of the ozone layer has started to reverse its course and the positive trend is therefore close.
The hole in the ozone will therefore close and return to "normal" by 2050. The positive effects will fall on all of us.
