    • Ozone is a molecule of oxygen with three atoms of oxygen, O3.
    • It covers the Earth’s atmosphere and is present in the stratosphere. It does not allow the harmful ultra-violet radiations coming from the sun to reach our Earth surface.
    • These ultra-violet radiations cause ionising effect, can cause cancer and genetic disorder in any life-forms.
    • The ozone is getting depleted at the south pole near Antartica. The ozone depletion is due to the halogens like CFC (chlorofluorocarbon) released in the air.
    • Chlorine and fluorine reacts with the ozone and splits it, thereby leading to formation of a big hole called ozone hole.
    • Thus, we need to protect the ozone layer from getting depleted by reducing the consumption of fossil-fuels and other factors which leads to the depletion of ozone layer.
