Select the way to control air pollution

Options

A. Using clean fuel.
B. Using water, wind and sun energy
C. Not using chlorofluorocarbons.
D. All of the above

Answer

To control air pollution, we can adopt several strategies. Here’s a step-by-step solution outlining effective ways to reduce air pollution:

### Step 1: Use Clean Fuels
- **Explanation**: Transitioning to cleaner fuels, such as compressed natural gas (CNG), can significantly reduce the amount of harmful emissions released into the atmosphere. CNG produces fewer pollutants compared to traditional fuels like petrol and diesel.

### Step 2: Utilize Renewable Energy Sources
- **Explanation**: Harnessing renewable energy sources such as water, wind, and solar energy can help in generating electricity without contributing to air pollution. These resources are abundant and do not emit harmful substances when used for energy production.
- **Water**: Hydroelectric power can be generated from flowing water, which is a clean energy source.
- **Wind**: Wind turbines convert wind energy into electricity, and this process does not produce air pollutants.
- **Sun**: Solar panels capture sunlight and convert it into electricity, again without emitting pollutants.

### Step 3: Avoid Chlorofluorocarbons (CFCs)
- **Explanation**: CFCs are chemicals that can harm the ozone layer and contribute to air pollution. By not using products that contain CFCs, such as certain refrigerants and aerosol sprays, we can help protect the atmosphere and reduce pollution.

### Summary of Control Measures:
1. **Use clean fuels like CNG** to reduce emissions.
2. **Utilize renewable energy sources** (water, wind, solar) for electricity generation.
3. **Avoid chlorofluorocarbons** to protect the ozone layer and reduce air pollution.
