Quizplus · Accepted Answer

Photochemical smog is primarily caused by the reaction of sunlight with pollutants such as nitrogen oxides and volatile organic compounds, which are emitted from sources such as car exhaust. Therefore, reducing the number of automobiles burning gasoline and the amount of evaporated gasoline would directly address the underlying cause of the smog problem, making it the most practical solution. Changes in weather patterns, such as producing more fog or less sunshine, would not address the root cause of the problem and may even exacerbate it. Reducing the amount of electricity generated using windmills would not have a direct impact on photochemical smog levels.
