Question:
Ageing of skin, cataract and skin cancer are the result of
Ageing of skin, cataract and skin cancer are the result of
Show Hint
Ozone = Sunscreen for the planet. Less ozone means more "sunburn" effects like cancer and ageing.
Updated On: Jul 4, 2026
- Acid rain
- Green-house effect
- Depletion of $O_{3}$ layer
- $CO$ Pollution
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
The ozone ($O_{3}$) layer in the stratosphere acts as a shield against harmful ultraviolet (UV) radiation from the sun.
Step 2: Meaning
When this layer is depleted, higher levels of UV-B radiation reach the earth's surface.
Step 3: Analysis
UV-B radiation is known to damage biological tissues, leading to mutations in DNA (skin cancer), damage to eye proteins (cataracts), and premature ageing of the skin.
Step 4: Conclusion
These health issues are direct consequences of ozone layer depletion. Final Answer: (C)
