Solution
Ozone present in the stratosphere is called as good ozone as this ozone absorbs UV rays from the sun which is harmful to living organisms. DNA and proteins of living organisms absorb UV rays and its high energy breaks down the chemical bonds within these molecules. This causes damage to skin cells and skin cancer of different types. A high dose of UV-B causes inflammation of the cornea called snow-blindness cataracts. This all is prevented by this stratosphere ozone as it absorbs UV rays.
