The ozone has been taken seriously. The Montreal Protocol with 180 countries have been formed.
The Chlorine in the CFC is the element that causes ozone depletion
the ozone depletion has been evident at the poles. Antarctica has the largest ozone hole.
This has been confirmed by the people performing experiments. CFC's cause depletion.
CFC's are responsible for depletion of ozone. They react with ozone to deplete it.
It is because ozone depletion takes place in cold regions. Antarctica is the one place where ozone hole has been noticed.
Ozone depletion causes UV to enter the earth. To stop it, CFC's have been banned.
CFC's is one cause. It has been banned to curb ozone depletion.
The government is taking measures for ozone layer. For it, CFC's have been banned.

Ozone depletion was first noticed in 1985, the same set of measurements that established the ozone hole. There is evidence that ozone has been more-or-less steadily increasingly depleted, worldwide, since the early 1700s.
The ozone depletion process began in the late 1970s and early 1980s with the discovery of the Antarctic ozone hole. This led to the realization that human activities, specifically the release of chlorofluorocarbons (CFCs) and other ozone-depleting substances, were contributing to the thinning of the ozone layer.
Global community has been helping in each way to prevent the ozone layer depletion. They have also taken all the mandatory steps.
