In order to halt or slow the advance of glaciers, the Tlingit tribe of the northwest coast of North America used to sacrifice dogs and slaves by throwing them into the glacier’s crevasses in the hopes of appeasing the ice spirit.

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?”

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.”

In 1919 a steel storage tank burst in Boston and spilled 2.3 million gallons of molasses, creating a twenty-five-foot-high wave that killed twenty-one people and tore buildings from foundations. The tank had leaked since its installation, but the company had, in response to complaints, merely painted it a concealing brown.

When Albert Einstein visited Beno Gutenberg, a seismologist at Caltech, in 1933, the two strolled around the Pasadena campus while Gutenberg explained earthquake science. Suddenly their wives arrived to inform them there had been a massive earthquake. “We had become so involved in seismology,” recalled Gutenberg later, “that we hadn’t noticed.”
