Question

What s being done to save the ozone layer?

Answer 1

The sun continuously pours about 3,273,305 Gigawatts of UVC and UVB energy into the Earth's atmosphere which goes into ozone manufacture and maintenance.  It is interesting to note that the disintegration of ozone, whether spontaneous or by chlorine-catalyst reaction, provides a larger, not smaller, collision cross-section for interception of UV radiation.

Meanwhile we continue to pour unburned hydrocarbons and carbon monoxide into the stratosphere, and the ozone thus depleted does not recombine into diatomic oxygen.  Have you noticed that almost no one is calling for a reduction in air travel?
