Ozone hole is a problem as it causes harmful UV rays to enter the earth. To avoid this, we have to stop the use of CFC's.
Ozone layer is studied by the help of satellites or probes. They calculate the concentration of ozone in the layer.
Pollution does not help the ozone layer. It only worsens the depletion condition.
In order to help the ozone layer stop the use of CFC's. They react with ozone to deplete it.
CFC's and ozone layer combined is a concern. It is the problem because CFC's destroy the ozone to a great content.
CFC's cause problems to ozone layer. They help in its depletion.
Ozone layer is a protective layer. The problem with it is its depletion.
Nothing is wrong with ozone layer. There is problem with absence of ozone layer.

The problem of ozone layer is worsening. It is due to many ODS working together.
Ozone hole is a problem as it causes harmful UV rays to enter the earth. To avoid this, we have to stop the use of CFC's.
Ozone layer is studied by the help of satellites or probes. They calculate the concentration of ozone in the layer.
Poking holes in ozone layer is a problem. A hole in ozone would cause the ultraviolet radiations to enter the surface.
Ozone is depleting. It is due to CFC's.
The ozone layer is breaking. It is because of the use of CFC's by humans.
Pollution does not help the ozone layer. It only worsens the depletion condition.
