Can the ozone layer be saved?
Chlorofluorocarbons or CFCs and bromide chemicals released to the atmosphere set off complex chain reaction that leads to the destruction of ozone molecules. It rises into the upper atmosphere when released. In the ozone layer, UV radiation striking CFC molecules causes chloride atoms to break away and collide with ozone molecules. Chlorine atom reacts with ozone to form chlorine monoxide, by stealing one oxygen atom and releasing an oxygen molecule. When free oxygen atoms collide with the chlorine monoxide, chlorine is released as the two oxygen atoms combine to form an oxygen molecule. The process thus sets into results in the destruction of more ozone. One chlorine atom can destroy up to a hundred thousand ozone molecules. 
YES! By phasing the use of CFCs, Halon, and other ODS, the ozone layer can be saved.

Stratospheric ozone are created and destroyed in a natural cycle. This balance has been maintained for millions of years and was disturbed by the release of ODS in the atmosphere beginning 1930s.

It is important to know that once ODS are phased out, the ozone layer will slowly repair itself.
 
What is being done to save the ozone layer?
The alarming rate of ozone depletion has led developed and developing countries to draw up an agreement known as the Montreal Protocol on Substances that Deplete the Ozone Layer on September 16, 1987. As of 2004, this agreement binds 186 signatory countries to take immediate steps towards ODS phaseout.
NAME OF ODS BASE LEVEL 1999 2002 2003 2005 2007 2010 2016 2040
CFC (Annex A) 1995-1997 freeze     50% 85% 100%    
CFC (Annex B) 1998-2000     20%   85% 100%    
Halons 1995-1997   freeze       100%    
Methyl Bromide 1995-2000   freeze   20%     100%  
Methyl Chloroform 1998-2000       30%     100%  
Carbon Tetrachloride (CTC) 1998-2000       85%

100%    
HCFC's 2015             freeze 100%
How do Ozone Depleting Substances (ODS) destroy the ozone molecules?
