Less use of CFC's
There is not actually a hole in the ozone layer. The ozone has been reduced below some limit.
Aerosols deplete the ozone by reacting with it. Ban on CFC's have been implemented.
The ozone layer might have started very early. As the UV hit the oxygen, ozone would have been created.
Not any more. The CFCs that were used as aerosols in the 1980s are responsible for the depletion of the ozone layer. These have been phased out and scientists hope the ozone layer will have recovered by about 2060.It emits gases that damage the ozone layer.
Not now. The CFCs that were used as aerosols in the 1980s are responsible for the depletion of the ozone layer. These have been phased out and scientists hope the ozone layer will have recovered by about 2060.
Ozone layer has been destroyed by CFC's. They react with ozone to deplete it.
There have been hundreds of ozone layer slogans in the past several years. There are many groups who are concerned about damage to the ozone layer and their campaigns and strikes have brought the problem to the attention of many other people.

No, there was no water near the ozone layer. The ozone layer has been protecting from the UV on it's own.

There have been various experiments measuring the ozone layer. The ozone over the poles is seen to have depleted.
Not now. The CFCs that were used as aerosols in the 1980s are responsible for the depletion of the ozone layer. These have been phased out and scientists hope the ozone layer will have recovered by about 2060.
The hole in ozone layer is pretty big. It has been shrinking however.
To protect ozone, we have to curb CFC's. They react with ozone to deplete it.
Ozone has been thinning because of man made chemicals. These are CFC's.
