Paul Erlich, the author of the blockbuster book The Population Bomb, was charismatic, telegenic, and absolutely terrifying Joined by his wife, Anne, he told Carson's massive audience that hundreds of millions of people were about to starve to death, and that nothing could stop it Eric's first appearance on the Tonight Show demonstrates a lot of things Not least how much popular TV has changed I'm struggling to imagine Carson's eventual successor, Jimmy Fallon giving an hour to say CIisPper inventor Jennifer Dudna. let alone without a lip sync battle but it also shows Just how influential Erich was We appeared on this tonight show more than twenty times The population bomb sold over two million copies and became one of the most popular science books of the twentieth century His works help popularize a broader population panic worldview. influence policymakers in the U. S. and abroad. including coercive family planning policies. in countries such as India and China I look at his book fundamentally change the world we live in today I need airl You died recently at ninety three. turned out to be spectacularly wrong wrrong in ways that have had major consequences for humanity But I want to dwell on something It's precisely because he was both so wrong and so influential. Doom saying remain so seductive and so dangerous Population Bomb, I suspect, was one of those of the moment books. It was more owned than red You didn't need to get far into it. to grap Eric's alarmist message You just need to read the opening lines battle to defeed all of humanity. is over the nineteen seventies Hundreds of millions of people will starve to death in spite of any crash programs embarked upon now And the book was just part of his lifelong campaign Ear predicted that sixty five million Americans would die of famine between nineteen eighty and nineteen eighty nine I told a British audience that by the year two thousand. The United Kingdom would be, quote, a small group of impoverished islands, inhabited by some seventy million hungry people He said India which is home to nearly six hundred million people in nineteen seventy. could never feed two hundred million more people. He said U. S. life expectancy would drop to forty two by nineteen eighty On Earthday, nineteen seventy, he declared that, quote In ten years, all important animal life in the sea. will be extinct Every one of these predictions was almost one hundred and eighty degrees in the wrong direction. in America As as much of the world Obesity became the true metabolic health crisis Not starvation UK at least last time checked still exists India is now a major agricultural exporter. and its population has nearly tripled. while hunger has fallen Marine life is stressed, Very much not extinct The bottom line is that instead of mass starvation The world experienced the greatest expansion of food production in human history Per capita calorie supply has risen consistently since nineteen sixty one Since the population bomb was published rates of hunger have dropped dramatically So what did Erlic miss For one thing You made be a common mistake He assumed line goes up The years leading up to the population Bomb's publication in nineteen sixty eight featured the steepest population increases in global history The trends were so on the nose for his thesis You could almost forgive Erich for assuming they would inevitably continue. Airlt look closer at the data. It would have revealed that even in the high growth nineteen sixties The world was already beenting ard are comparatively low fertility present and North America All seeing their fertility rates fall The society is urbanized Women were educated. and child mortality drop plus The population bomb was published in nineteen sixty eight which was eight years after birth control pill was introduced. Eirlook many others of his time, to be fair It appea to assume that these patterns wouldn't apply as the countries of the gllobal South developed They did As these social and economic trends spread around the world Fertility kept falling from around five children per woman globally, when the population bomb was published two point three today B bigger mistake wasn't misreading data He was failing to account for people. People like Norman Borlag Corlg was an egronomist from rural Iowa who with the support of the Rockefeller Foundation developed high yielding dwarf wheat varieties transformed agriculture in countries like Mexico India and Pakistan India Erlic had written off in racially tinge ways didn't just avoid famine It became self sufficient in food production The population bomb was explicit about Eric's worldview Population growth was the quote cancer. must be cut out saw people or at least People in the global South as little more than mouths to feed Each fighting for shares, a static pie And he dismissed the part the global South could play in finding solutions Bl and the Green Revolution researchers by contrast, Solve them as minds to solve problems Cking figuring out ways to make that pie bigger Erlx fundamentally zero some worldview. may have gotten him global recognition. And sadly remains far too prevalent blinded him to the future And that's why he ended up on the losing end of one of the most famous wagers. in academic history We'll be back after a short break Support for this show comes from Shopify Starting a business is not easy.

It feels good to find what you're looking for. It feels good to Gaico Julian Simon economist at the University of Maryland believe the opposite Everything, Erlich believed Simon's argument was simple People are the world's most valuable resource. Human ingenuity responds to scarcity by finding new supplies, substitutes inefficiencies And that meant the commodity prices adjusted for inflation fall over time Not rise In nineteen eighty Simon challenged Erlk to a bet anyy raw materials, any time period longer than a year, and wager on whether prices would go up We're down Erlic and two colleagues chose five medals you proper Nickel. him and tungsten. and bought one thousand worth of them on paper. It be settled in nineteen ninety During those ten years The world's population grew by more than eight hundred million the largest one decade increase in human history Erlic was wrong Okay All five metedals fell in inflation adjusted price october nineteen ninety Eric acknowledged Smonson the check for five hundred and seventy six dollars. and seven cents Erlek didn't do was revised his views to reflect the facts. which is what makes him more than a cautionary tale bad predictions In two thousand nine. He told an interviewer, the population bomb was quote wayay too optimistic In twenty fifteen This is his langage, quote, would be even more apocalyptic today. On sixty minutes in twenty twenty three at age ninety He told correspondent Scott Pelly that quote The next few decades will be the end of the kind of civilization we're used to. It didnn't matter that the world had spent fifty five years Proving him wr Et didn't blink And Erk's wrongness had real consequences He endorsed cutting off food aid to countries he considered hopeless including India and Egypt. broader population panic movement He helped create influence coercive real world policies India's forced sterilization campaigns during the nineteen seventies.

More dramatic The hitchhog gets Carson Fox gets ignored There's also a structural incentive problem Predict things we find. And you're wrong You're irresponsible Disaster, and you're right You're a genius Predict disaster and you're wrong Forget b Just assume you were a little early It was notable to me The sub headline of the New York Times Obituary of Erich. C his predictions not wrong, but mature None of this means Iignore environmental problems Climate change is real Erlic was relatively early in flagging it B the Versue us. which is closer to his actual academic expertise remains legitimately alarming And we shouldn't repeat Erk's mistakes in the opposite direction. It's because things have been getting better does not automatically mean That trend will continue especially who make perverse and self defeating policy choices The real lesson Erk's life. is that Assuming doom leads to worse policy than assuming agency Right offph a country is hopeless Can you justify setutting its food a Assume people are the problem. and you end up sterilizing them against their will Juin Simon died in nineteen ninety eight never approaching Erlk's level public fame H signature line The ultimate resource peopleople killed Spirited and hopeful people who will exert their wills and imaginations For their own benefit as well is in a spirit of faith and social concern You probably wouldn't have heard that and theter M show
