Population

If you are looking for a pointer for the future of the world, the free-diving fisherwomen on the matriarchal, shamanistic South Korean island of Jeju are not an obvious example of where we’re heading. Because the haenyeo are famously unique. And famously hardy. But what is happening to them should concern us all. In simple wetsuits they spend hours in the cold, clear waters, seeking out sea slugs, oysters, conches and abalone. They are fiercely independent – they spearheaded resistance to the Japanese in the 1930s and 1940s. But here’s the thing, as Nari (age 70) tells me in the haenyeo’s coastal mud-room: ‘We are probably the last. We have

We held a small party to celebrate the news that the UK had seen its largest rise in population in 50 years: a jump of 1 per cent in only 12 months to a respectable total of 68.3 million people. Just crisps and soft drinks, you understand. Nothing wildly extravagant. All patriots feel proud of the speed with which our numbers have been rising of late, because naturally we wish for the UK to be the biggest and best in the world – and we are on our way. The rights of the likes of Ardit outweigh the rights of the rest of us not to be burgled At the

For anyone tempted to try to predict humanity’s future, Paul Ehrlich’s 1968 book The Population Bomb is a cautionary tale. Feeding on the then popular Malthusian belief that the world was doomed by high birth rates, Ehrlich predicted: ‘In the 1970s hundreds of millions of people will starve to death.’ He came up with drastic solutions, including adding chemicals to drinking water to sterilise the population. Ehrlich, like many others, got it wrong. What he needed to worry about was declining birth rates and population collapse. Nearly 60 years on, many predict the world will soon reproduce at less than the replacement rate. But by my calculations, we’re already there.

Within limits Do 20mph speed limits save lives? – A 2018 report by Atkins/AECOM/UCL found that 51% of motorists conformed to the new limit (47% in residential areas and 65% in city centres). – When a 20mph zone replaced a 30mph one the median speed fell by 0.7mph in residential areas and 0.9mph in city centres. It was found that there was insufficient evidence to judge whether the 20mph limit reduced casualties: while accident rates had tended to fall within the zones, the same was true of comparator zones which had remained at 30mph. – Only one area of 20mph zones (in Brighton) had seen a significant fall in casualties

Well, we’ve been terrifically amused and amusing at the expense of Pope Francis, who this week declared at a Vatican audience that: ‘Many couples do not have children because they don’t want them, or have just one because they don’t want any more, but have two dogs, two cats… oh yes, dogs and cats take the place of children.’ It was, he said, proof of a ‘certain selfishness… it makes us laugh but it’s true. Renouncing parenthood diminishes us. It takes away our humanity.’ This was inevitably cue for British commentators to weigh up the merits of cats and dogs versus children, and for some to pronounce in favour of
