They think ozone is disappearing. It is because of increased UV radiations.
There have been various experiments measuring the ozone layer. The ozone over the poles is seen to have depleted.
It is because of CFC's. They react with ozone to deplete it.
Ozone disappearance is a problem. It is because it allows the UV rays to pass through.
Scientists hope the ozone layer will have recovered by around 2050.
The main reason that scientists think is contributing to destruction of ozone depletion is the use of CFC's. These are chemicals present in various substances and when released destroy ozone molecules.
They think that because of its components. It contains Chlorine which depletes the ozone.

Scientists have many theories. According to them, ozone was created by UV rays.
Accouring to the scientists, the main cause of depletion of ozone layer is the use of CFc's. These CFCs react with ozone present in the ozone layer and deplete it.
Scientists believe that the ozone layer is disappearing because there is a large hole in it. This hole was not there years ago.
Ozone is disappearing. It is because of the increasing CFC's.
The scientists think that it is made by CFC. They react with ozone to deplete it.
