This is not enough, but at least it was a good starting point. It is always best to talk and discuss problems than to do nothing at all. This is why learning about Ozone depletion like you are doing, is the most important step towards a safe environment in the future.
WHAT CAN BE DONE?
Ozone is a natural gas and is naturally replenished over time. This means if we can do something to balance the natural production with its depletion, there should not be a problem. Unfortunately, it does not work like that.
People ask if we cannot produce our own ozone gas to replenish what is lost in the stratosphere. That’s a good question. The sun naturally produces ozone with immense energy and over time. To do the same, we will be looking at using immense energy too, about twice the energy used in the USA. That is just not practical.
The only way to do that is to remove the excess chlorine and bromine from the stratosphere. And the only way to do that is to stop making CFCs and several other chemicals. This is why in the 1990s a meeting of the worlds big nations met and agreed to reduce the usage of CFCs and also encouraged other nations to do the same. That was decided in the Montreal Protocol.
