In the late 19th- and early 20th-century London, the newly industrial metropolis contended with an issue known as "pea soup fog." The city's factories, foundries, and power plants were belching nitrogen oxides, sulfur oxides, smoke, and particulate matter into the air, forming a layer of visible pollution that typically quippy British residents named after a particularly opaque soup. We know it as the portmanteau of "smoke" and "fog": "smog." The modern stuff, the stuff that hovers famously over Los Angeles, is a more advanced strain. There, and more extremely in cities like Delhi and Beijing, car fumes percolate in the atmosphere and react with sunlight, creating secondary pollutants that thicken the air. (Ozone is one, famous secondary pollutant.) A multitude of cars and sun produces more than just dark tans.
It's bad for the earth, the animals, and us, but smog can also be strangely beautiful. While we wish the earth's cities nothing but crystal-clear, clover-smelling air, at least the particular-choked ether makes for some violently beautiful sunsets and a murky moodiness befitting the best LA noir thrillers. As we condemn pollution and look forward to legislation to bring about a cleaner world, take a gander at the perverse beauty of our current smoggy situation. As with those luscious, carcinogenic new-car smells that we can't help but gulp down, smog-photography (phosmography?) has a fatal tastiness to it. Enjoy.
