I feel stupid asking this. But cities and countries who have smog and a major amount of air pollution. Why doesn't the wind blow it away or move it overtime? Is there that much pollution?

It depends. Some areas with really bad smog have problems where the air in an area doesn’t mix with the surrounding air, trapping it and making it harder for the smog to dissipate. This is a common issue for cities in inland valleys.
