Ozone depletion from the atmosphere becomes the reason for causing which of the following diseases?

The correct answer is Skin cancer.

Key Points

• The gradual thinning of the Earth's ozone layer in the upper atmosphere caused by the discharge of chemical compounds containing gaseous chlorine or bromine from industry and other human activities is referred to as ozone depletion.
• The thinning is mainly noticeable over Antarctica and in the polar regions.
• Depletion raises the quantity of ultraviolet (UV) radiation reaching the Earth's surface, raising the risk of skin cancer, cataracts, and genetic and immune system damage.
• The Montreal Protocol was the first of several international agreements to prohibit the production and use of ozone-depleting chemicals, and it was ratified in 1987.

Additional Information

• Heart stroke:
  • When blood supply to the heart is obstructed, the heart muscle is severely damaged, resulting in a heart attack.
  • Coronary artery disease, which happens when plaque builds up in the arteries, is the leading cause of heart attacks.
  • Over time, the plaque restricts blood flow, forcing the heart to work harder – and potentially leading to damaged or failing heart muscles.
• Brain stroke:
  • A stroke occurs when the blood flow to any area of the brain is cut off. It's also known as a brain stroke.
  • If blood supply to the brain is interrupted for more than a few seconds and the brain is deprived of oxygen and blood, brain cells die and the abilities regulated by that portion of the brain are lost.
• Tuberculosis:
  • Tuberculosis (TB) is a potentially fatal infectious illness affecting mostly the lungs.
  • Tuberculosis bacteria are communicated from person to person via minute droplets discharged into the air by coughs and sneezes.
