Question

Quizplus · Accepted Answer

Transportation is the major source of air pollution in most cities. Improving the public transportation system and promoting carpooling can significantly reduce the number of cars on the road, thus reducing air pollution. This would be a logical action to take in order to improve the air quality. Negotiating with another large city for their pollution control is not a viable option since it may not be feasible or effective to have a large dependence on another city's air quality control. Moving or closing cattle feedlots may be helpful but the improvement may be limited since the feedlots just represent one source of pollution. Reducing the amount of CFCs used locally would not result in significant air quality improvement as CFC levels are already generally being lowered because of international agreements. Removing a hydroelectric dam would be an alternative action not related to air quality.
