Nothing? Nothing is done only by the Americans who are refusing to sign the Kyoto Protocol. (Correct me if I'm wrong)
The simplest and most significant change is to cut off the use of ChloroFluoroCarbons (CFCs) and HydroChloroFluoroCarbons (HCFCs). They are inert and harmless at ground level but are detrimental to ozone molecules at the stratosphere. In fact, it is the Chlorine atom found in the CFCs and HCFCs that destroys the Ozone molecules.
CFCs & HCFCs were mainly used in blowing agents, solvents and refrigerants in air-conditioners and refrigerators.
They are now replaced by other substances such as HydroFluoroCarbons(HFCs). The HFCs do not contain any chlorine atoms and hence do not harm the ozone layer. Other substitutes are alkanes (such as ethane) and nitrogen gas.
Thats what I learnt. Through live searches I found this;

To prevent the thinning of the ozone layer, we can reduce the use of ozone-depleting substances like chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). Additionally, promoting the use of eco-friendly alternatives, such as hydrofluorocarbons (HFCs), can help mitigate ozone layer depletion. Global agreements like the Montreal Protocol have been crucial in phasing out harmful substances and protecting the ozone layer.
Ozone has been thinning because of man made chemicals. These are CFC's.
Thinning of ozone is a global topic. It has been addressed worldwide.
The thinning of ozone layer has been due to various reasons. CFC's, carbon monoxide etc are some.
This is a thinning (by about 2/3, of the ozone over the Antarctic during the spring time, towards the end of the long winter night in the south pole. There is no actual hole in the layer. This has occurred for centuries, in fact the thinnest we know the layer has ever been is in 1858, before man started using cfc's. A similar thinning occurs, to a much smaller extent in the Arctic during the end of it's winter night also. The thinning is much smaller in the Arctic and NASA even reffers to this thin area as the "Dimple" due to the small size.
The thinning of the ozone layer can be reversed by reducing the use of ozone-depleting substances such as chlorofluorocarbons (CFCs) and bromine-containing compounds. International agreements like the Montreal Protocol have been successful in phasing out the production and use of these harmful substances. Continued global cooperation and adherence to these regulations are essential to allow the ozone layer to recover.
The thinning of ozone layer causes the harmful UV radiation to enter the earth's surface. These are high frequency radiations which can cause various fatal problems to life on earth.
Reducing emissions of ozone-depleting substances like chlorofluorocarbons (CFCs) is key to solving the thinning of the ozone layer. International agreements like the Montreal Protocol have been successful in phasing out these substances. Continued monitoring and compliance with regulations are also essential to protect the ozone layer.
Human activities, such as the release of chlorofluorocarbons (CFCs) and other ozone-depleting substances, are primarily responsible for the thinning of the ozone layer. These chemicals break down ozone molecules in the stratosphere, leading to the formation of the ozone hole. The Montreal Protocol, an international agreement, has been instrumental in phasing out the production and use of these harmful substances to protect the ozone layer.
The thinning of the ozone layer leads to increased levels of harmful ultraviolet (UV) radiation reaching the Earth's surface. This can result in negative impacts on human health, such as higher rates of skin cancer and cataracts, as well as harm to marine life, ecosystems, and agriculture. Efforts have been made to reduce ozone-depleting substances to help mitigate this issue.
To prevent ozone depletion many steps are taken. It is treated by afforestation.
as we know there are 2 holes in the ozone layer, over Asia and another 1 over the north pole - it is all apart of god's plan. so don't go freaking out if there is a hole. god knows what he is doing. everything is for a reason...
