In recent years the number of species driven to extinction has increased dramatically. Which of the following is nota reason for this?

Options

A. Overexploitation
B. Habitat destruction
C. Introduction of predators
D. Natural predation

Answer

To answer the question regarding the reasons for the increase in species extinction, we can analyze the options provided:

1. **Overexploitation**: This refers to the excessive use of species for resources such as food, medicine, and materials. When species are overharvested, their populations can decline to the point of extinction. This is indeed a reason for extinction.

2. **Habitat Destruction**: This occurs when natural habitats are altered or destroyed, often due to human activities like deforestation, urbanization, and agriculture. The loss of habitat can lead to the decline of species that depend on those habitats for survival, making it a significant reason for extinction.

3. **Introduction of Predators**: This involves the introduction of non-native species that can prey on native species. These exotic predators can disrupt local ecosystems and lead to the decline or extinction of native species that may not have evolved defenses against them. This is also a valid reason for extinction.

4. **Natural Predation**: This is a natural process where predators hunt prey as part of the food chain. It is a normal ecological interaction that helps maintain balance in ecosystems. Unlike the other options, natural predation does not lead to extinction in the same way that overexploitation, habitat destruction, or introduction of predators does.

Based on this analysis, the option that is **not** a reason for the increase in species extinction is **Natural Predation**.

### Steps to Solution:
1. Identify the options provided regarding reasons for extinction.
2. Analyze each option to determine if it contributes to species extinction.
3. Conclude which option does not contribute to extinction.
