Yes, many countries have entered in to a pact to stop harmful chemicals that can destroy the ozone layer. Environmental awareness should be increased in order to save the ozone layer.

Can the hole of the Ozone Layer be repaired?
The ozone hole can be repaired by curbing the use of CFCs. If there are no man made ozone destroying substances, the ozone layer will replenish itself.
Has ozone layer hole been repaired?
The ozone hole has not yet being repaired. It is on the path of improving.
How can the ozone hole be repaired?
The Sun sends out UV-C radiation, and oxygen and nitrogen stop this. These molecules shatter upon absorption. Some of the oxygen atoms end up making ozone. The equilibrium value of ozone is based on creation by UV-C from the Sun, destruction by absorbing UV-B from the Sun (it is the only gas in our atmosphere that does this), and destruction by contaminants. As contaminants go up, more UV-B makes it through to the surface of the Earth... where it can damage DNA directly (it will pass through our skin, just as it will through plant structures to get to its DNA). So if the contaminants can be reduced (from whatever source), the ozone layer can repair itself. See the link below for what these contaminants are:
What activities of man contribute to the depletion of ozone layer?
In the 1970s humans released CFCs into the atmosphere. It was used as a gas in aerosol cans, refrigerators and air conditioners. Production of CFCs was phased out after the Montreal Protocol in 1989. Scientists hope the ozone layer will be repaired around 2050.
How can you retify the ozone layer depletion?
The issue of depletion of the ozone layer is mostly a naturally occurring event and has always occured during the end of the winter months at both poles. Man's involvement in this issue has been largely corrected through the banning of CFC's. As long as we have oxygen in our atmosphere and a sun to convert O2 into O3, we will have an ozone layer. Scientists hope that the ozone layer may have completely recovered by 2060.

Has ozone layer hole been repaired?
The ozone hole has not yet being repaired. It is on the path of improving.
Has the ozone layer recovered since the ban?
Yes it has. ban on ozone has repaired the ozone layer.
What still needs done to the ozone layer?
Ozone needs to be repaired. For this we need to stop using CFC's.
Has man repaired the ozone layer?
Man has depleted the ozone layer. He has done this by continues usage of CFC's.
Why hasn't the ozone layer repaired itself?
Ozone does repairs itself and replenishes. But when rate of destruction is more then it destroys.
How can the Ozone depletion be stopped and the damage repaired?
the hole in ozone is basically due to the chloroflourocarbon or CFC. therefore its use should be stopped.
How can the ozone hole above Antarctica repair?
Yes, it can be repaired. It is possible if we curb the use of ODS i.e. ozone depleting substances.
Why hasn't the ozone layer repaired itself fully since the ban?
CFCs, the chlorofluorocarbon gases that destroy the ozone, remain active in the atmosphere for 50 to 75 years.The chlorine molecule that detaches from the CFC to attack the ozone emerges from the encounter unscathed and lives to fight another day.CFCs also take about ten years to rise up to the lower stratosphere, where the ozone layer is.All these reasons are why scientists hope that the ozone layer will have repaired itself fully by the year 2060.
What can be done to help ozone depletion?
You would not desire to help deplete ozone. Ozone thins at the Antarctic towards the end of the winter there due to the long nights and absence of sunlight for long periods. When the sun returns the ozone slowly reappears. Chlorofluorocarbons (CFCs) that were used in refrigerators and aerosols are the main destroyers of the ozone layer. Scientists hope that the holes will be completely repaired by 2050.
What are people doing to control the ozone?
The 1987 Montreal Protocol got all countries to agree to phase out chlorofluorocarbons (CFCs) which were then used in aerosol sprays and refrigeration. Chlorine from CFCs destroyed ozone in the ozone layer which led to the weakening of the layer. Now in 2012 scientists believe that ozone seems to be no longer being destroyed, but it will take up to 2060 before the ozone layer has repaired itself.
What effect do air conditioning gases have on the ozone layer?
The gas that used to be used in air conditioners and refrigerators, freon, or chlorofluorocarbons (CFCs) would damage the ozone layer. Chlorine would separate from the gas and attack the ozone molecules. These gases are no longer used in air conditioning units. If no further damage occurs the ozone layer will have repaired itself by 2060.
