Which of the following is not a consequence of deforestation ?

Options

A. increase in soil erosion
B. increase in earth's temperature
C. decrease in rainfall
D. decrease in floods

Answer

To determine which of the following is not a consequence of deforestation, let's analyze the options provided:

1. **Increase in soil erosion**: Deforestation leads to the removal of trees, which hold the soil in place. Without trees, the soil is more susceptible to erosion by wind and water. Therefore, this is a consequence of deforestation.

2. **Increase in Earth's temperature**: Trees absorb carbon dioxide (CO2), a greenhouse gas. When trees are cut down, the amount of CO2 in the atmosphere increases, contributing to global warming and an increase in Earth's temperature. Thus, this too is a consequence of deforestation.

3. **Decrease in rainfall**: Deforestation can disrupt local climates and reduce the amount of moisture released into the atmosphere, leading to decreased rainfall. This is also a consequence of deforestation.

4. **Decrease in floods**: This option suggests that deforestation leads to fewer floods. However, this is not true. In fact, deforestation often leads to an increase in floods because trees help to absorb and slow down rainfall. Without trees, water runs off more quickly, leading to higher flood risks.

Based on this analysis, the correct answer is that **decrease in floods** is not a consequence of deforestation.

### Step-by-Step Solution:
1. **Identify the effects of deforestation**: Understand what happens when trees are cut down.
2. **Analyze each option**: Go through each option to see if it is a consequence of deforestation.
3. **Determine the correct answer**: Identify which option does not belong as a consequence of deforestation.
