Accounts varied of the Great Famine of 1315–22, during which more than 10 percent of Europe’s population died. In Flanders: “Parents killed their children and children killed parents, and the bodies of executed criminals were eagerly snatched from the gallows.” In France: “There was no wine in the whole kingdom.”

The destruction of Sodom and Gomorrah may have been caused by an earthquake that occurred through the Great Rift Valley around 1900 bc. The “brimstone and fire” described in the Bible would have been due to petroleum and gases present in the area igniting the cities.

“Pompeii like any other town,” Herman Melville wrote in his journal during an 1867 visit. “Same old humanity. All the same whether one be dead or alive. Pompeii comfortable sermon. Like Pompeii better than Paris.”

Sixteenth-century “father of mineralogy” Georgius Agricola critiqued “these attacks, which are so annoying,” made by those protesting how mining exterminated animals and poisoned brooks and streams. “With the metals that are melted from the ore,” he explained, “birds without number, edible beasts, and fish can be purchased elsewhere and brought to these mountainous regions.”

The opening of a particle accelerator at Brookhaven National Laboratory in 2000 inspired fears that high-speed collisions might launch a chain reaction that could turn the earth into a hyperdense sphere about one hundred meters across. A risk calculation determined this to be unlikely; if the collider were to run for ten years, the chance was no greater than 1 in 50 million. “The word unlikely, however many times it is repeated,” wrote concerned scientists, “just isn’t enough to assuage our fears of this total disaster.”
