Why is damage to the ozone layer a cause for concern? What steps are being taken to limit this damage?

Dear Student

Ozone layer in the strastosphere is very helpful in shielding harmful UV rays. In absence of ozone layer heavy damage to organism may occur. It may cause diseases like skin cancer, cataract, reduced crop production etc.
The damage is limited bye UNEP (United Nations Environment Programme), it has forged an agreement to freeze for CFC production in 1986.
CFC– Chlorofluorocarbons used as refrigerants and in fire extinguishers.

Thanks
