Detailed explanation-1: -Ozone in the stratosphere protects life on Earth from harmful ultraviolet (UV) radiation and is therefore often called ‘good’ ozone. This is in contrast to ozone in the troposphere, the lowest layer of the atmosphere, where it is an air pollutant and can be harmful to humans, animals and vegetation.

Detailed explanation-2: -The depletion of the ozone layer leads, on the average, to an increase in ground-level ultraviolet radiation, because ozone is an effective absorber of ultraviolet radiation.

Detailed explanation-3: -To protect yourself from UV radiation: Wear a wide brim hat to shade your face, head, ears, and neck. Wear wraparound sunglasses that block both UVA and UVB rays. Use sunscreen with sun protection factor (SPF) 15 or higher, for both UVA and UVB protection. Avoid indoor tanning.

Detailed explanation-4: -The ozone layer is known as the natural sunscreen, it absorbs and blocks the majority of the sun’s UV radiation.
