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

The damage to the ozone layer is a cause for concern because: 

• Ozone layer will not be able to filter out the UV rays efficiently and this will cause various skin problems such as skin darkening and skin cancer. 

• Ozone layer maintains a steady temperature on the planet. Damage to the layer might result in the death of many phytoplanktons that leads to increased global warming. 

• Chlorofluorocarbons (CFC’s) are compounds that damage the ozone layer. To limit the damage to the ozone layer, the release of CFCs into the atmosphere must be reduced.

• CFCs used as refrigerants and in fire extinguishers should be replaced with environmentally- safe alternatives. Also, the release of CFCs through industrial activities should be controlled.
