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...
We know that the ozone depletion is caused by CFC's. To prevent depletion, CFC's are banned.
Ozone layer is depletion is happening in the stratosphere of the earth's atmosphere. It is majorly concentrated over Antarctica's atmosphere.
Ozone layer is depletion is happening in the stratosphere of the earth's atmosphere. It is majorly concentrated over Antarctica's atmosphere.
The ozone depletion is the thinning of ozone layer. It is most prominent over Antarctica.
The solution for ozone depletion is curbing CFC's. They could prevent ozone depletion.

It is because ozone depletion takes place in cold regions. Antarctica is the one place where ozone hole has been noticed.
The ozone depletion first happened over Antarctica. It is because of the cold temperatures.
Antarctica has seen the ozone hole. It is because of the cool weather there.
The ozone depletion requires low temperatures. It is because ozone is depleted in Antarctica.
it describes two distincts, but related observations
