Today's Wisdom - The Green Wall, Little Boots and Chanel

Happy Friday and welcome back to A Little Wiser! Whether you're soaking up the sun or, like us in London, pretending it's summer anyway…. we hope you're ready for the weekend. A reminder to keep an eye out as you read today, we're always looking to share your knowledge! Today’s wisdom explores:

Grab your coffee and let’s dive in.

In 1978, the Chinese government launched what would become the largest ecological engineering project in human history, a program so vast in its ambition that Western scientists initially struggled to believe it was real. The Three-North Shelter Forest Program, known internationally as the Green Wall of China, set out to plant a belt of trees stretching 4,500 kilometers across the northern edge of the country, from the western province of Xinjiang to the eastern coast of Heilongjiang. The goal is to halt the advance of the Gobi and Kubuqi deserts which is swallowing millions of acres of farmland every year and generating sandstorms severe enough to bury villages, close airports, and deposit dust as far away as South Korea and Japan.

The scale of what has been achieved is genuinely staggering. By the early 2020s, China had planted approximately 66 billion trees across the project zone, and satellite data from NASA confirmed that China alone accounted for a quarter of the entire planet's net increase in green leaf area between 2000 and 2017 (a good fact to tell those who don’t recycle because “China is destroying the planet anyway“)! Entire counties in Inner Mongolia that were classified as severely desertified in the 1980s now have functioning agricultural land and tree cover. The Kubuqi Desert, once described by the United Nations as one of the most dangerous deserts on earth for the communities surrounding it, has had roughly a third of its area revegetated through a combination of state planting programs and private enterprise, with companies paid by the government to stabilize sand dunes using a technique involving straw grids that create enough shelter for saplings to take root.

The project's critics, however, have raised concerns that have grown louder as the science has matured. A significant portion of the trees planted in the early decades were monocultures of a single species, often poplar or elm, chosen for their fast growth rather than their ecological compatibility with the local environment. Monoculture forests are dramatically more vulnerable to pest infestations, and in several regions entire plantations were wiped out by bark beetles and other insects that a biodiverse forest would have naturally resisted. A 2019 study published in Science Advances found that many planted trees in arid zones were drawing on groundwater reserves faster than rainfall could replenish them, raising the possibility that some areas could experience an ecological collapse once those reserves run dry. Yet, few scientists would dispute that the Great Green Wall represents a genuine and determined attempt to push back against one of the most pressing environmental challenges of our time. China is attempting something that has never been done before at this scale, and the outcome will carry lessons, for better or worse, for every country watching desertification accelerate in a warming world.

Gaius Julius Caesar Germanicus, known to history by his childhood nickname Caligula, meaning "little boot," inherited the Roman Empire in 37 AD to scenes of extraordinary public jubilation. His father Germanicus had been one of Rome's most beloved generals, and after the long reign of Tiberius, who had spent his final years on the island of Capri conducting purges of the Roman Senate, the arrival of a young and charismatic emperor felt like a genuine dawn. The Roman population sacrificed 160,000 animals in the first three months of Caligula's reign as a gesture of collective relief and hope. Within a year it had gone catastrophically wrong.

Caligula began his reign with genuine competence, recalling those unjustly exiled by Tiberius, publishing the imperial budget for the first time in decades, and staging spectacular public games. Then, approximately eight months in, he fell seriously ill. The man who recovered bore little resemblance to the one who had taken the throne. He declared himself a living god, appearing in public dressed as Jupiter, Neptune, and even the goddess Venus. He had men flogged for his own amusement during dinner, forced senators to run alongside his litter for miles, and according to Suetonius, appointed his horse Incitatus to the priesthood and allegedly planned to make him consul, an act that was either a genuine expression of madness or a calculated insult to a Senate he had grown to despise.

What is less disputed is the financial and political devastation of his four-year reign. Caligula burned through the vast treasury surplus left by Tiberius, estimated at nearly three billion sesterces, in under a year. He funded an obsessive building program, extravagant banquets, and a bizarre military campaign against Britain that ended with his soldiers ordered to collect seashells from the English Channel as spoils of war against the ocean god Neptune. He was assassinated in January 41 AD by officers of his own Praetorian Guard, who stabbed him thirty times in a palace corridor, making him the first Roman emperor to be killed by his own protectors at twenty-eight years old. The Roman Senate's immediate instinct was to restore the republic, a debate that lasted precisely as long as it took the Praetorian Guard to find his uncle Claudius hiding behind a curtain in the palace and declare him emperor instead.

Every expert has one thing they wish the public understood properly.

Gabrielle Bonheur Chanel was born in 1883 in a French poorhouse, the daughter of a street vendor who deposited her in an orphanage run by nuns after her mother died, where she learned to sew. She would spend the rest of her life lying about every detail of that childhood, inventing a more palatable origin story so convincingly that many of the fabrications made it into her official biography. By the time she opened her first millinery shop in Paris in 1910, European women were still corseted, layered in petticoats, and decorated with enormous feathered hats. Chanel looked at all of it and began dismantling it piece by piece, borrowing liberally from menswear, stripping away ornamentation, and replacing restriction with ease of movement in a way that the fashion world had never seriously attempted.

The innovations came in a concentrated burst during and after World War One, when fabric shortages and the practical demands of women entering the workforce created a cultural opening she was perfectly positioned to exploit. She popularized jersey fabric, previously used only for men's underwear, as material for women's clothing. She introduced the little black dress in 1926, a garment that Vogue memorably compared to the Ford Model T for its democratic accessibility, and which remains in production in essentially the same form a century later. Chanel No. 5, launched in 1921 and named because it was the fifth sample presented to her by the perfumer Ernest Beaux, became the best-selling fragrance in history, in part because Marilyn Monroe famously told a reporter in 1952 that she wore nothing to bed but a few drops of it.

The full picture of Chanel's life resists easy admiration. During the German occupation of Paris in World War Two, she lived openly at the Hotel Ritz with a Nazi officer named Hans Gunther von Dincklage and was documented by French intelligence as a German agent who used her connections to attempt to negotiate a back-channel peace deal between Britain and the Third Reich. She was arrested at the liberation of Paris in 1944 but released within hours, almost certainly due to intervention by Winston Churchill, who knew her socially and wanted to avoid a scandal. She spent the subsequent decades in Switzerland before returning to Paris in 1954 to relaunch her house and reclaim her position at the summit of fashion, which she held until her death in 1971. The orphan from the poorhouse became the most influential designer in history, and the story of how she got there contains just about everything the twentieth century had to offer.
