Which everyday action helps manage air resources?

• A. Recycling bottles
• B. Planting trees
• C. Turning off lights
• D. Using public transportation

Answer: (D)

Maintaining clean air means reducing the pollutants released into the atmosphere from everyday activities. Using public transportation directly lowers the number of vehicles on the road, which cuts per-person emissions of pollutants and greenhouse gases. When more people ride buses or trains, fewer individual cars burn fuel, leading to better air quality and less smog, especially in busy areas. Some other actions do help in related ways—recycling bottles saves energy used in manufacturing, which can reduce air pollution indirectly; planting trees improves air quality but more gradually as trees grow and absorb carbon; turning off lights saves electricity and can cut power-plant emissions, but the overall impact per person is typically smaller than switching to mass transit. So choosing public transportation provides the most immediate and noticeable impact on managing air resources.
