What public strategy could reduce health problems from air pollution?

Shifting to hybrid and public transportation alternatives is a public strategy that can significantly reduce health problems associated with air pollution. This approach addresses the root cause of air pollution by minimizing the reliance on fossil-fuel-powered vehicles that emit harmful pollutants. Hybrid vehicles, which use a combination of gasoline and electricity, generally produce fewer emissions than traditional gasoline vehicles. Furthermore, public transportation options, such as buses and trains, can reduce the number of individual cars on the road, thereby decreasing overall emissions and improving air quality.

Encouraging the adoption of these cleaner transportation options not only helps to lower the levels of pollutants in the air but also promotes healthier lifestyles by facilitating increased physical activity (e.g., walking to bus stops). By reducing the amount of vehicular traffic, this strategy can lead to significant public health benefits, including a decrease in respiratory diseases and cardiovascular issues related to poor air quality.
