Fog, Smog, and Poisoned Rain deals with air pollution and its consequences. Beginning with a definition of the problem, it then examines the causes of particular types of pollution and the way the pollution is disseminated; the geographic distribution of the phenomenon; and historical records. The book closes with a look into the future and a discussion of the ways in which air pollution can be reduced. In addition to pollution resulting from human activities the book also describes "natural pollution" from volcanic eruptions, lake beds, and gaseous emissions from plants and trees.
