The main reason of disturbance of biological diversity is

Options

A. Greenhouse effect
B. Hunting
C. Soil erosion
D. Destruction of natural habitats

Answer

### Step-by-Step Solution:

1. **Understanding Biodiversity**:
- Biodiversity refers to the variety of life forms on Earth, including plants, animals, microorganisms, and the ecosystems they inhabit. It encompasses all living organisms and their interactions within their environments.

2. **Identifying Causes of Disturbance**:
- Several factors can disturb biological diversity, including:
- Greenhouse effect
- Hunting
- Soil erosion
- Destruction of natural habitats

3. **Analyzing Each Option**:
- **Greenhouse Effect**: While it contributes to global warming and can impact biodiversity, it is not the primary cause of disturbance.
- **Hunting**: This leads to the decline of certain animal populations, but it is not the main reason for widespread biodiversity loss.
- **Soil Erosion**: This affects soil biodiversity and can impact plant life, but again, it is not the primary cause.
- **Destruction of Natural Habitats**: This is the most significant factor. It directly leads to the loss of shelter and food for many organisms, resulting in their inability to survive.

4. **Conclusion**:
- The main reason for the disturbance of biological diversity is the destruction of natural habitats. This destruction can be due to human activities such as deforestation, urbanization, and agricultural expansion, which severely impacts the ecosystems and the species that depend on them.

### Final Answer:
The main reason for the disturbance of biological diversity is the destruction of natural habitats.
