Detailed explanation-1: -This ozone layer in the Earth’s stratosphere absorbs most of the Sun’s ultraviolet (UV) radiation that may cause skin cancer. Thus decreasing levels of ozone in the stratosphere may result in an increase in the occurrence of skin cancer in humans.
Detailed explanation-2: -The ozone layer protects us all from the damage that too much UV radiation can cause to our skin and eyes. By protecting the ozone layer, the Montreal Protocol may have prevented up to 2 million cases of skin cancer each year by 2030 and avoided millions of cases of cataracts worldwide.
Detailed explanation-3: -Ozone depletion can cause increased amounts of UV radiation to reach the Earth which can lead to more cases of skin cancer, cataracts, and impaired immune systems. Too much exposure to UV is believed to be contributing to the increase in melanoma, the most fatal of all skin cancers.
