Major causes of human-induced extinctions of species include all of the following, except

Options

A. climate modification
B. overexploitation
C. habitat destruction
D. captive propagation

Answer

To answer the question regarding the major causes of human-induced extinctions of species, we will analyze each option provided and determine which one does not belong to the list of causes.

### Step-by-Step Solution:

1. **Identify Human-Induced Extinction Causes**:
- The question asks about human-induced extinctions, which are typically caused by various human activities.

2. **Evaluate Each Cause**:
- **Climate Modification**: This refers to changes in the climate due to human activities such as pollution. It can lead to habitat loss and make environments uninhabitable for certain species. This is a known cause of extinction.
- **Overexploitation**: This involves the excessive use of resources, leading to a decline in species populations. This is also a recognized cause of extinction.
- **Habitat Destruction**: This occurs when natural habitats are altered or destroyed due to human activities like deforestation, urbanization, and industrialization. This is a major cause of extinction.
- **Captive Propagation**: This is a conservation method where species are bred in controlled environments to increase their populations. This practice aims to prevent extinction rather than cause it.

3. **Determine the Odd One Out**:
- Among the options, climate modification, overexploitation, and habitat destruction are all linked to causing extinctions. In contrast, captive propagation is a conservation strategy that works against extinction.

4. **Conclusion**:
- Therefore, the correct answer to the question is that the major cause of human-induced extinction of species that does not belong to the list is **captive propagation**.

### Final Answer:
Captive propagation
