Which of the following strategy is not a correct approach to reduce global warming ?

Options

A. Cutting down use of fossil fuel
B. Reducing deforestation
C. Improving efficiency of energy use
D. Cutting trees and increasing growth of human population

Answer

To determine which strategy is not a correct approach to reduce global warming, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Identify the Options**: We need to look at the four strategies given in the question.
- Option 1: Cutting down fossil fuels
- Option 2: Reducing deforestation
- Option 3: Improving efficiency of energy use
- Option 4: Cutting trees and increasing growth of human population

2. **Analyze Option 1**:
- **Cutting down fossil fuels**: Fossil fuels, when burned, release carbon dioxide, a greenhouse gas that contributes to global warming. Reducing the use of fossil fuels will decrease carbon emissions and help combat global warming.
- **Conclusion**: This is a correct approach.

3. **Analyze Option 2**:
- **Reducing deforestation**: Deforestation leads to fewer trees that can absorb carbon dioxide through photosynthesis. Reducing deforestation means more trees to absorb CO2, thus helping to mitigate global warming.
- **Conclusion**: This is a correct approach.

4. **Analyze Option 3**:
- **Improving efficiency of energy use**: By using energy more efficiently, we can reduce the amount of fossil fuels needed for energy production. This would lead to lower carbon emissions, contributing positively to the fight against global warming.
- **Conclusion**: This is a correct approach.

5. **Analyze Option 4**:
- **Cutting trees and increasing growth of human population**: Cutting trees reduces the number of plants available to absorb CO2, and an increasing human population typically leads to higher energy consumption and fossil fuel use. This strategy would exacerbate global warming.
- **Conclusion**: This is NOT a correct approach.

6. **Final Answer**: The strategy that is not a correct approach to reduce global warming is **Option 4: Cutting trees and increasing growth of human population**.
