What is Ozone layer? Explain the effects of the depletion of ozone layer.

Ozone layer is a protective layer in the stratosphere which prevents the entry of the harmful radiations from the sun.

When the layer of ozone in the stratosphere gets depleted, the harmful UV radiations can enter into the Earth's atmosphere and cause adverse effects. These radiations can cause mutations in the genetic material of the living organisms. These radiations acts on the harmful gases and release radicals which can cause bleaching of the plants and animal tissues. These radiations can also cause skin cancer.
