Paul Ehrlich’s bestselling book The Population Bomb opens with an apocalyptic paragraph. “The battle to feed all of humanity is over,” it states. “In the 1970s and 1980s hundreds of millions of people will starve to death in spite of any crash programs embarked upon now. At this late date nothing can prevent a substantial increase in the world death rate.”Professor Ehrlich, who died last week, made a simple argument. The global population was outrunning our capacity to produce enough food to feed everyone. Famine, disease and nuclear Armageddon would follow if the population was not controlled.The book made him a celebrity, and he regularly spoke in public, warning of the imminent threat to humanity. Sometimes his warnings were quite vague in terms of the timescale, but other times not - he was reported as saying in 1968 that if current trends continued, by the year 2000, the UK would be a “small group of impoverished islands, inhabited by some 70 million hungry people". 
"If I were a gambler," he was quoted as saying, "I would take even money that England will not exist in the year 2000".But the UK did not collapse, the global death rate did not increase, and we have more food per person now than when he wrote the book. So, what went wrong with Paul Ehrlich's predictions of a population apocalypse?If you’ve seen a number or claim that you think More or Less should look at, email moreorless@bbc.co.uk
