Pestilence is Back

In the wonderful Terry Pratchett novel, “Good Omens”, the Four Horsemen of the Apocalypse are: War, Death, Famine, and Pollution. Pestilence had faded in modern times and been replaced by Pollution who rode a Vespa that leaked oil and gasoline everywhere it went. Now with COVID-19, Pestilence has re-appeared and with blue skys returning, it is Pollution that is fading from the scene.
