Mass transit can help reduce air pollution in urban cities because there are fewer cars on the roads, creating less pollution.

Mass transit can alleviate urban air pollution by reducing the number of vehicles on the road, promoting cleaner energy sources, and encouraging non-motorized transport. Government policies that support public transportation further enhance these benefits, ultimately leading to better air quality and public health. Thus, efficient mass transit systems are essential for creating cleaner, more sustainable urban environments.
