Depletion of ozone layer can not cause

Options

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

Answer

To solve the question regarding the effects of ozone layer depletion, we need to analyze each of the options provided and determine which one is not caused by the depletion of the ozone layer.

### Step-by-Step Solution:

1. **Understanding Ozone Layer Depletion**: The ozone layer is crucial for absorbing the majority of the sun's harmful ultraviolet (UV) radiation. When the ozone layer is depleted, more UV radiation reaches the Earth's surface.

2. **Analyzing the First Option - Damage to DNA**:
- UV radiation can cause direct damage to the DNA in living organisms. This can lead to genetic mutations and disorders.
- **Conclusion**: Damage to DNA can indeed be caused by ozone layer depletion.

3. **Analyzing the Second Option - Skin Cancer**:
- Increased exposure to UV radiation due to ozone depletion is a well-known risk factor for skin cancer.
- **Conclusion**: Skin cancer can be caused by ozone layer depletion.

4. **Analyzing the Third Option - Cataracts**:
- UV radiation can also lead to cataracts, which is a clouding of the lens in the eye, affecting vision.
- **Conclusion**: Cataracts can be caused by ozone layer depletion.

5. **Analyzing the Fourth Option - Records**:
- The term "records" does not relate to any biological or health effects caused by UV radiation. It is not a recognized consequence of ozone layer depletion.
- **Conclusion**: Records cannot be caused by ozone layer depletion.

### Final Answer:
The depletion of the ozone layer cannot cause **records**.
