Options

A. Reduce `CO_(2)` in the air
B. increase `CO_(2)` in the air
C. reduce `O_(2)` in the air
D. reduce `CO_(2)` and increase `O_(2)` in the air

Answer

To answer the question "Planting more and more trees helps to:", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Photosynthesis**:
- Trees and plants perform photosynthesis, which is the process by which they convert carbon dioxide (CO2) and water (H2O) into glucose (C6H12O6) and oxygen (O2) using sunlight.
- The chemical equation for photosynthesis is:
\[ 6CO_2 + 6H_2O \xrightarrow{\text{sunlight}} C_6H_{12}O_6 + 6O_2 \]

2. **Role of Trees in Carbon Dioxide Absorption**:
- During photosynthesis, trees absorb carbon dioxide from the atmosphere. This helps to reduce the overall concentration of CO2 in the air.

3. **Role of Trees in Oxygen Production**:
- As a byproduct of photosynthesis, trees release oxygen into the atmosphere. This increases the level of oxygen available for living organisms.

4. **Evaluating the Options**:
- Now, let's evaluate the options provided in the question:
- **Option 1**: Reduce CO2 in the air - This is true.
- **Option 2**: Increase CO2 in the air - This is false.
- **Option 3**: Reduce O2 in the air - This is false.
- **Option 4**: Increase O2 in the air - This is true.

5. **Conclusion**:
- Based on the analysis, planting more trees helps to reduce carbon dioxide in the air and increase oxygen in the air. Therefore, the correct answer is **Option 4**.

### Final Answer:
Planting more and more trees helps to reduce CO2 in the air and increase O2 in the air.
