Solution

Stratospheric ozone is considered good for humans and other life forms because it absorbs ultraviolet (UV)-B radiation from the Sun. If not absorbed, UV-B would reach Earth’s surface in amounts that are harmful to a variety of life forms. In humans, increased exposure to UV-B increases the risk of skin cancer, cataracts, and a suppressed immune system.
