Climate change and its effects are in good health and continue to wreak havoc in different parts of the planet, however, not all bad news. The size of the hole in the ozone layer has been constantly reduced in recent years, until now reaching the levels it had in 1988, almost 30 years ago.
The ban on so-called CFCs and the worldwide effort to pursue these types of compounds has done most of the work, although not all. It must be said that if the reduction of the hole in the ozone layer is a very good sign, its reasons are not so much: global warming has done its part to reduce the amount of gases than the original.
Due to the greater circulation of hot air in Antarctica, ozone-depleting gases have gradually disappeared from the stratosphere, something that is good and bad at the same time, although it serves to make us a very good idea of how the action human always affects in one way or another the climate and living conditions on earth.
Chlorofluorocarbons (CFCs) were banned in most countries following the Montreal Protocol, approved in 1989 in the Canadian city. Since then these substances have been replaced by others that do not cause harm or cause less damage to the ozone layer, although it has not been until recently when they have begun to notice the benefits of the agreement.
CFCs emitted into the atmosphere for years by different types of spray and sprayers caused the ozone layer to be reduced for a long time after the ban, reaching its peak around the year 2000. Since then and for 17 years, the ozone layer has been recovering its good health, although with some ups and downs.
The presence of this protective layer around our planet is important for animal and plant life, since it filters the sun’s rays to avoid damage in different types of tissues. Do not forget that exposure to these unfiltered can greatly increase the risk of skin cancer and other skin diseases.
