In recent decades, cities, especially metropolises, have faced more pollution than ever before. As a result, a controversy has arisen over what is the primary reason behind this predicament. While some people attribute it to the marked increase in cars, others would contend that the chief among all causes is industrial activities, which from my perspective, the latter is more accurate. Although cars, undoubtedly, cause a detrimental effect on the urban environment, the catastrophe industrialism brings in its wake is much more disturbing.
