Paul Ehrlich’s prediction could not have been more wrong. History is littered with experts – and not just leaders of fringe cults – who predicted the end of the world and got it wrong. Ehrlich is just one in a long line of such doom-and-gloomers.
Back in the 1970s, each classroom of my Pittsburgh public grade school had dozens of copies of The Population Bomb lining its bookshelves.
I don’t recall ever actually studying The Population Bomb. But it’s clear that Pittsburgh Public Schools thought they might need to prepare us for the ensuing global famine.
Of course, Ehrlich’s prediction could not have been more wrong.
The Population Bomb Fizzles
Fast-forward to 2018, and the obesity rate in the U.S. is among the highest in the world.
The biggest health problem isn’t that Americans are starving.
It’s that Americans are eating too much.
History is littered with experts – and not just leaders of fringe cults – who predicted the end of the world and got it wrong.
Ehrlich is just one in a long line of such doom-and-gloomers. His thinking traces directly back to the original Cassandra of famines, Thomas Malthus, the English economist best known for his theory of population.
In his 1798 An Essay on the Principle of Population, Malthus argued that as human populations grow exponentially, food production will not keep pace.
Unless men refrain from “pursuing the dictate of nature in an early attachment to one woman,” the world will run out of food and famines will ensue.
No doubt inspired by Malthus, Ehrlich dutifully limited his own family to one child. […]
The Power of Human Ingenuity
On its face, the Simon-Ehrlich bet was about the future price of five metals between 1980 and 1990.
On a deeper level, it was about a conflict of visions concerning the future of humanity.
Was mankind’s future constrained by the Earth’s ever-depleting resources… or by the limits of human ingenuity?
The verdict from history is clear.
Charles Maurice and Charles W. Smithson at Texas A&M University studied the history of natural resources over 10,000 years.
They found that temporary scarcities in natural resources are the norm.
They also found that same temporary scarcity always led to an improved substitute. […]
Human ingenuity has always been successful in overcoming crises that once seemed inevitable.
Ehrlich was right about one thing: The world’s population has continued to expand.
Today, the global population stands at 7.6 billion.
That’s double the 3.8 billion when Ehrlich published The Population Bomb.
And yet, despite Ehrlich’s predictions, no devastating famine threatening humanity’s existence ever ensued.
The reason is straightforward.
Food production increased faster than the population – a pattern that has repeated since Malthus.
Today, the average person is healthier, wealthier and better fed than in 1968. Infant mortality has declined. Life expectancy has increased.
Ironically, both Japan and Europe do have a population problem. But the problem is not the threat of famine due to too many mouths to feed.
It’s that women are having too few children to maintain current population levels.
Here is a final irony…
Ehrlich has spent his entire academic career ensconced at Stanford University – the intellectual Godfather of Silicon Valley.
Silicon Valley, in turn, embodies the optimism and progress that has always overcome the relentless logic of Malthusian doom and gloom.
I can’t help but wonder how an academic who spent his life surrounded by symbols of human progress can be so pessimistic.
Yet at 85, Ehrlich remains unapologetic for his (so far) misguided predictions.
Ehrlich has said that if he wrote The Population Bomb today, he’d be even more apocalyptic than he was in 1968.
Like all doom-and-gloomers, Ehrlich won’t concede he’s wrong.
He’s just “early…”
