Pea Soup Fog

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Pea soup, or a pea souper, is a type of visible air pollution, a thick and often yellowish smog caused by the burning of soft coal. Smog, a portmanteau of "smoke" and "fog," can be lethal, and even the healthy may be inconvenienced by it.An 1871 New York Times article refers to "London, particularly, where the population are periodically submerged in a fog of the consistency of pea soup..." The fogs caused large numbers of deaths from respiratory problems until the early 20th century, when homes began migrating to the suburbs and use of coal for industrial activities became more efficient or was replaced by electricity.
