The first mass extinction on earth occurred around 2.5 billion years ago, when a photosynthesizing bacterium appeared and released so much oxygen into the atmosphere that anaerobic life was largely wiped out. This is often called the Great Oxygenation Event, the Oxygen Catastrophe, or the Oxygen Holocaust. 

Opening night of Henry James’ Guy Domville, on January 5, 1895, was “an unmitigated disaster,” James wrote in a letter, “hooted at, as I was hooted at myself, by a brutal mob, and fruitless of any of the consequences for which I have striven.” The play’s reception, he wrote, “has completely sickened me with the theater and made me feel, at any rate for the present, like washing my hands of it forever.”

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.”

Hatches of Rocky Mountain locusts (Melanoplus spretus) in 1874 and 1875 brought swarms up to 1,800 miles long and 110 miles wide across the Great Plains. Numbers were estimated in the trillions. Farmers risked starvation. The swarm is believed to have been the largest mass of living insects ever witnessed by modern man—but within thirty years the species disappeared. “I can’t believe M. spretus is extinct,” said ecologist Dan Otte in 2014. “But where to look for it?”

The first known legal use of the phrase act of God was in a 1581 English case concerning property inheritance. It referred, in that instance, to death, declared by the judge to be among “those things which are inevitable by the act of God, which no industry can avoid, nor policy prevent.”
