Can the Ozone Hole Be Repaired?

"Can't we fix just the ozone hole by pumping ozone into it?" This is the question that my sister asks me whenever we get into  debate about ozone hole and sadly I don't have an answer. But why should one be sad when there is internet available to help you solve the unsolved queries :-D.

Well, here is what I understand from an article that I just read. 

1. First of all, ozone production requires a lot of energy. Obviously we will need a huge quantity of ozone to fill the ozone hole, and we can not prepare that large quantity on land because it requires a lot of energy. In atmosphere this large amount of energy comes from the sun. 
2. Secondly, if ozone is leaked during production, it will act as a pollutant in our environment. Yes!! Ozone is good in the stratosphere, but bad in the troposphere. In troposphere (the layer of atmosphere in which we live), ozone acts as a pollutant.
   
   
   
   
3. Lastly, we do not need to patch the ozone layer ourselves. It has the ability to patch itself. The pollutants that are already present will fall off eventually. What we need to do is to stop adding pollutants that deplete the ozone layer and follow the Montreal Protocol.  According to EPA, if we keep on following Montreal Protocol, the ozone hole may patch itself by 2050.

Montreal Protocol

This Protocol was established in 1987. More than 180 countries agreed to address the problem in the Montreal Protocol. In signing the protocol, those countries agreed to root out the use of ozone-depleting chemicals like CFCs, halons and carbon tetrachloride.

So, do your best and stop or decrease the use of ozone depleting substances.
