There might be no better example than Beijing, China, to show how industrialization made air quality worse and how quickly legislation can improve air quality.

This is a graph depicting air pollution (PM2.5 concentrations) in Beijing, China, from 1850 to 2021. It includes a color-coded scale indicating levels of air quality, ranging from "Extremely Poor" to "Very Good." There's also a white line that shows the same information. The air quality level in Beijing has been pretty steady and fair since the start of the Industrial Revolution, but rapidly got worse in the 1960s to the point where it was extremely poor in the 2010s. It started to improve drastically after the 2008 Olympics in Beijing, and is now significantly better. It is still poor.
