Deforestation has adverse effects on the ecosystem. Which of the following statements about deforestation is incorrect?

Options

A. It leads to soil erosion
B. It leads to global warming
C. It increases the occurrence of floods
D. It increases the water-holding capacity of soil

Answer

To determine which statement about deforestation is incorrect, we need to analyze the effects of deforestation on the ecosystem based on the provided options.

### Step-by-Step Solution:

1. **Understand Deforestation**: Deforestation refers to the clearing or removal of forests or trees, often to make way for agricultural activities, urban development, or other non-forest uses.

2. **Identify the Effects of Deforestation**:
- Deforestation leads to soil erosion, which removes the nutrient-rich top layer of soil, making it difficult for plants to grow.
- It contributes to global warming by increasing carbon dioxide levels in the atmosphere, as trees that absorb CO2 are cut down.
- Deforestation can increase the occurrence of floods, as trees help to absorb rainfall and maintain the water cycle.

3. **Evaluate the Given Options**:
- **Option 1**: "It leads to soil erosion." - This statement is correct.
- **Option 2**: "It contributes to global warming." - This statement is correct.
- **Option 3**: "It increases the occurrence of floods." - This statement is correct.
- **Option 4**: "It increases the water holding capacity of the soil." - This statement is incorrect because deforestation actually decreases the water holding capacity of the soil.

4. **Conclusion**: The incorrect statement regarding the adverse effects of deforestation is **Option 4**: "It increases the water holding capacity of the soil."

### Final Answer:
The incorrect statement about deforestation is: **Option 4** - "It increases the water holding capacity of the soil."
