In 1865, W. Stanley Jevons predicted that with coal reserves of 90 billion tons, England would run out within 100 years. Today, the country has between three trillion and 23 trillion ton, enough to last Britain for centuries.
In 1914, the Bureau of Mines fretted that with a total future production limit of 5.7 billion barrels, the U.S. only had about a ten-year supply of oil. Today, a hundred years later, we’re estimated to have 36 billion barrels left in the ground.
In 1968, Paul Ehrlich predicted that because of an inability to produce enough food, hundreds of millions of people would starve in the 1970s. Instead, the population has doubled—from 3.5 to 7 billion—and the number of famine victims from 1970-2015 combined is less than in the 1960s.
Each time experts predicted a decline in natural resources would be detrimental to population growth. And each time history proved the experts wrong.
