Depletion of ozone layer can not cause

Options

A. Damage of DNA
B. Skin cancer
C. Cataract
D. Rickets

Answer

To address the question regarding what the depletion of the ozone layer cannot cause, we can break down the information as follows:

### Step-by-Step Solution:

1. **Understanding the Ozone Layer**:
- The ozone layer is located in the stratosphere and serves as a protective barrier that absorbs the majority of the sun's harmful ultraviolet (UV) radiation.

2. **Effects of Ozone Layer Depletion**:
- When the ozone layer is depleted, more UV radiation reaches the Earth's surface. This can lead to various health issues and environmental impacts.

3. **Health Issues Linked to Ozone Depletion**:
- Increased UV radiation can cause skin cancer, cataracts, and other immune deficiencies.
- Skin cancer is a significant risk as UV rays can damage the skin cells.
- Cataracts can develop due to UV exposure, affecting vision.
- Immune deficiencies can arise from the body's weakened ability to fight diseases when exposed to higher levels of UV radiation.

4. **Identifying What Ozone Depletion Cannot Cause**:
- The question specifically asks what the depletion of the ozone layer cannot cause.
- Rickets is mentioned as a condition that is not caused by ozone layer depletion. Rickets is primarily due to a deficiency in vitamin D, which is essential for bone health, and is not directly linked to UV radiation exposure from ozone depletion.

5. **Conclusion**:
- Therefore, the correct answer to the question is that the depletion of the ozone layer cannot cause rickets.

### Final Answer:
The depletion of the ozone layer cannot cause **rickets** (Option D).
