Which of the following is not one of the prime health risk associated with greater UV radiation through the atmosphere due to depletion of stratospheric ozone ?

Options

A. Reduced Immune System
B. Damage to eyes
C. Increased liver cancer
D. Increased skin cancer

Answer

To solve the question, we need to identify which of the listed options is not a prime health risk associated with increased UV radiation due to the depletion of stratospheric ozone. Here’s a step-by-step breakdown:

### Step-by-Step Solution:

1. **Understanding UV Radiation and Ozone Depletion**:
- The stratospheric ozone layer protects the Earth from harmful ultraviolet (UV) radiation. When this layer is depleted, more UV radiation reaches the Earth's surface.

2. **Analyzing the Health Risks**:
- **Reduced Immune System**: Increased UV radiation can suppress the immune system, making individuals more susceptible to infections and diseases.
- **Damage to Eyes**: UV radiation can cause significant damage to the eyes, including cataracts and other eye disorders, potentially leading to blindness.
- **Increased Skin Cancer**: UV radiation is a well-known risk factor for skin cancer. It can cause mutations in skin cells, leading to various forms of skin cancer.
- **Increased Liver Cancer**: Liver cancer is typically associated with factors such as chronic hepatitis, alcohol consumption, and certain toxins, rather than UV radiation.

3. **Identifying the Incorrect Option**:
- Among the options given, "increased liver cancer" is not directly linked to UV radiation. The other three options (reduced immune system, damage to eyes, and increased skin cancer) are all associated with the effects of increased UV radiation.

4. **Conclusion**:
- Therefore, the correct answer to the question is **increased liver cancer**, as it is not one of the prime health risks associated with greater UV radiation due to the depletion of stratospheric ozone.

### Final Answer:
**Increased liver cancer** is not one of the prime health risks associated with greater UV radiation due to the depletion of stratospheric ozone.
