Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The environmental cause for increase in skin cancer, cataract and mutation is
A
Acid rain
B
Global warming
C
Nuclear winter
D
Ozone depletion
Explanation: 

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 depletion increases the biologically harmful solar ultraviolet radiation reaching the surface of the Earth, which leads to a variety of adverse effects, including an increase in the incidence of skin cancer.

Detailed explanation-3: -Exposure to ultraviolet (UV) radiation from the sun plays a major role in the development of skin cancer. People who live at high altitudes or in areas with bright sunlight year-round have a higher risk of developing skin cancer. People who spend a lot of time outside during the midday hours also have a higher risk.

Detailed explanation-4: -Hence, the correct answer is ‘Ozone Depletion’.

Detailed explanation-5: -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.
