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.
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.
The ozone layer hole over Antarctica has shown signs of improvement since the 1980s, thanks to international efforts to reduce the use of ozone-depleting substances. However, it is not completely repaired yet and continues to be monitored closely. Continued global cooperation and adherence to environmental agreements are essential for further healing of the ozone layer.
No, lightning does not repair the ozone layer. Lightning can actually contribute to the depletion of ozone by producing nitrogen oxides, which are ozone-depleting substances. The ozone layer is repaired naturally through complex chemical processes over time.
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:
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.

Yes it has. ban on ozone has repaired the ozone layer.
Man has depleted the ozone layer. He has done this by continues usage of CFC's.
Ozone needs to be repaired. For this we need to stop using CFC's.
Ozone does repairs itself and replenishes. But when rate of destruction is more then it destroys.

the hole in ozone is basically due to the chloroflourocarbon or CFC. therefore its use should be stopped.
Yes, it can be repaired. It is possible if we curb the use of ODS i.e. ozone depleting substances.
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.

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.
