Damage to the ozone layer is a cause for concern because the harmful ultraviolet (LTV) radiatioo from the sun will reach the earth. This radiation is highly damaging to organisms.To repair the ozone layer, then, we must stop releasing ozone-depleting compounds into the atmosphere. In 1987, more than 180 countries agreed to address the problem in the Montreal Protocol.

The ozone layer is a blanket of gases that envelops the Earth. Ozone layer functions as a protective shield for the living beings on the planet. The main function of the ozone layer is to filter out the harmful ultra-violet rays of the Sun.

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

→ It will not be able to filter out the ultra-violet 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 (CFCs) 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.
