1) Minimize the use of CFC's i.e. chlorofluorocarbons because they are the ones resulting in the maximum ozone depletion
2) The flight of rockets in the layers of atmosphere specially the stratospheric layer should be controlled.
3) The vehicles should be checked for pollution specially in the continents near Antarctica because the winds carry the greenhouse gases to the poles which cause the global warming as well as the ozone depletion.
The ozone hole, and its size varies by time of year. No point in answering that part of the question.As to what is being done to prevent ozone layer depletion, we are asking silly questions on the internet. So far we have banned CFCs, which have been shown to deplete ozone (Nature also makes some, but we cannot fine Her). We still fly aircraft high in the atmosphere, even though we know this also depletes ozone. Other than that, we thump our chests, and point fingers elsewhere...
The ozone layer is a single layer. So there is no point of WHICH ozone layer.
Antarctica is located at the southern-most point of the earth.
Ninety degrees S, the South Pole, is properly the southern-most 'point' on earth.
Melting point: 80.7 K, -192.5 °CBoiling point: 161.3 K, -111.9 °C
the south pole {Antarctica} Antarctica is a continent. The South Pole is not Antarctica, it is the point where the Earth's axis is directly touching the surface. It is also the southernmost point of Earth.

Yes
Your answer depends on your starting point.
The ozone layer does not do any harm. So there is no point protecting earth from it.
Ozone is yes a pollutant at ground level. It causes carious respiratory problems.
