The words “air pollution” may sound archaic or inflated. There is a sense that air has gotten dramatically cleaner and is not as worrisome a problem as some other environmental issues. Air rarely makes national news anymore, unless it’s about dirty air in another country, or unless there is speculation that a brown cloud is creeping over from China, dirtying the air in California – a theory that has yet to be proven. More accurately, America is dirtying its own air in cities from Los Angeles to Pittsburgh.
