Answer :

Ozone layer is the layer formed by ozone (O3) and is found in the Earth’s stratosphere. This layer protects the earth from the ultraviolet (UV) radiation coming from the sun, by absorbing them.

The increased content of Chlorofluorocarbons (CFCs) arising from usage of aerosol sprays, and cleaning solvents caused a huge breakdown of ozone, resulting in ozone layer depletion.


This has resulted in UV radiation entering the atmosphere and caused a sudden increase in overall temperature, due to the trapping of the heat by greenhouse gases like carbon dioxide. This ultimately leads to “global warming”. This leads to the melting of polar ice caps, and other environmental issues. Humans on exposure to UV radiation can cause skin cancers as well.


To resolve the ozone layer depletion problem internationally, policies were introduced to minimise or avoid the usage of CFC included aerosol sprays, and refrigerants. On an individual basis, one could,


plant more trees so that the increased amount of greenhouse gases are absorbed by the trees.


usage of aerosol sprays or refrigerants that do not contain CFCs.


replacing incandescent light bulbs with fluorescent lamps, as they are void of halogen content.


limit the usage of private vehicles whenever necessary, so as to minimise the emission of greenhouse gases.
