Detailed explanation-1: -The ozone layer is present in the atmosphere, and it prevents harmful UV radiation from entering into the Earth which has the capability to cause skin cancer, cataracts in human beings. UV is a nonionizing radiation that induces mutation by producing thymidine dimers.

Detailed explanation-2: -Ozone layer depletion causes increased UV radiation levels at the Earth’s surface, which is damaging to human health. Negative effects include increases in certain types of skin cancers, eye cataracts and immune deficiency disorders.

Detailed explanation-3: -Ultraviolet radiation from sunlight contributes to age-related cataract and skin cancer.

Detailed explanation-4: -Complete answer: Increasing skin cancer and a high mutation rate are the results of Ozone depletion. An increased amount of manufactured chemicals such as manufactured halocarbon refrigerants, solvents, propellants, and foam-blowing agents are the major causes of ozone depletion in the stratosphere.
