Multicultural commuters in Kingston Upon Thames town center, London.
A glance at news headlines could lead one to believe our world has lost to tribalism and hate. In just the last few years, we've seen white supremacists march openly in American streets, extremist forces target cultural sites serving as reminders of humanity's shared heritage, places of worship terrorized, minorities blamed and assaulted over myths about novel coronavirus's origins, and leaders propose a myriad of attempts to reject refugees and migrants.
This is a part of today's reality, but it's worth remembering that news headlines aren't a trend analysis. They are a collection of reports and instances that tell only one side of our story—often the scariest and most extreme part.
Far from being pushed to the fringes, cosmopolitanism and the ethics of diversity may be enjoying a heyday according to Pew Research Center data from 11 emerging countries.
Does diversity improve lives?
The center surveyed more than 28,000 peoples across Columbia, India, Jordan, Kenya, Lebanon, Mexico, Tunisia, Venezuela, Vietnam, South African, and the Philippines on their opinions of diversity within their borders. These countries were chosen based on their middle-income status, differing degrees of technology ownership, and high levels of migration (internal or external).
The survey asked respondents how they viewed increasing numbers of other races, religions, and nationalities and what effect that had on the quality of life in their countries. Additional questions were tailored to a country's unique demographics and circumstances.
For example, respondents in the Philippines were asked how favorably they viewed Muslims and Christians, while Tunisians were asked about Sunnis and Shiites. Others, such as Mexico and Lebanon, were asked about asylum seekers fleeing to their countries.
Pew found that "[a]cross the 11 countries surveyed, more said their countries are better off thanks to the increasing number of people of different races, ethnic groups, and nationalities who live there." A minority said the increase made no difference, and an even smaller minority said their country was worse off.
Testing tribalism
Lebanon and Jordan took in millions of Syrian refugees during the civil war, helping to explain their complex relationship with diversity in their borders.
When looking at results from individual countries, the picture becomes much more nuanced. A majority of respondents from India, Columbia, the Philippines, Kenya, and Venezuela agreed with the statement that increased diversity made their countries better places to live. Conversely, a minority agreed with the same statement in Tunisia, Mexico, Jordan, and Lebanon.
The reasons for these divergences seem to stem not only from deep historical divides but also current events. Lebanon, which held the most negative views of diversity among the eleven, took in an estimated 1.5 million Syrian refugees, a massive influx for a country of around 7 million. Jordan too saw a massive wave of asylum seekers from the civil war; likewise, its respondents held that increasing numbers of different peoples made life in their country worse.
Mexico has also seen a surge of asylum seekers from Central American countries, yet its overall view wasn't as unfavorable as either Jordan or Lebanon. However, it was the only country in the set to have a majority hold that increasing ethnic and religious diversity made no difference to the quality of life. And about half those surveyed did hold negative views toward refugees.
But while current unrest in some regions has strained relations, it's not the whole story that refugees and migrants generate negativity toward others. Views differ widely.
Kenya, for example, maintains large refugee camps housing asylum seekers from Somalia and South Sudan, yet half of the country's respondents believed this multicultural status improved life in their country. And a majority held approving opinions of refugees.
Similarly, about half of respondents from Venezuela, Vietnam, and Jordan rated migrant and refugee groups favorably. Yes, Jordan.
Though a majority of Jordanians believe increasingly diverse peoples make their country worse, they nonetheless hold agreeable views of refugees. The researchers speculate this divergence may stem from the fact that Jordan hosts two large refugee groups—recent Syrian refugees and Palestinian refugees who have been in the country since the conflicts of the mid-20th century. They found that Jordanians who self-identified as Palestinians viewed refugees more favorably.
Getting used to each other
So, what leads to improved views of multiculturalism? According to Pew's data, those with the most positive views on racial, ethnic, and religious diversity were those who interacted most with these groups. More contact equaled more positive views.
In all of the countries, younger adults were more likely to interact with people of different backgrounds, and except for Jordan, they also held more favorable views of others. The same held true for those who attained higher levels of education.
This data mirrors another Pew survey in which researchers asked Americans their views on increased racial and ethnic diversity.
Around 58 percent of Americans said increasing numbers of diverse people would make the United States a better place to live. Only 9 percent said it would make the country worse, while 31 percent said it didn't make a difference. Opinions were split along partisan lines, with more Democrats viewing the statement favorably than Republicans.
But like the 11 emerging countries, Americans varied by age and education, too. Fifteen percent of respondents 65 and older believed growing multiculturalism made the U.S. worse—the highest of any age group. And 70 percent of college graduates saw diversity in a positive light, compared to 45 percent of those with a high school diploma or less school.
The survey's complete results can be found here, while the survey on American attitudes on diversity is here.
A future toward acceptance
These data suggest that the world hasn't succumbed to a new era of tribalism and hate. Far from it. The beliefs of cosmopolitanism and ethics of diversity are, in fact, spreading across many of the world's emerging countries and will likely increase as subsequent generations become more educated and integrated. That progress may be uneven, but it's real and measurable.
An appreciation of, even desire for, diversity won't end the tragic events that generate eye-catching headlines, but it can make our shared futures more manageable. As Kwame Anthony Apiah wrote in his book "Cosmopolitanism: Ethics in a World of Strangers": "I am urging that we should learn about people in other places, take an interest in their civilizations, their arguments, their errors, their achievements, not because that will bring us to agreement, but because it will help us get used to one another."

"If you're brave enough to try, you might be able to catch a train from UnLondon to Parisn't, or No York, or Helsunki, or Lost Angeles, or Sans Francisco, or Hong Gone, or Romeless."
China Miéville's fantasy novel Un Lun Dun is set in an eerie mirror version of London. In it, he hints that other cities have similar doubles. On the list that he offhandedly rattles off, Paris stands out. Because the City of Light really does have a twisted sister. Below Paris Overground is Paris Underground, the City of Darkness.
Most people will have heard of the Catacombs of Paris: subterranean charnel houses for the bones of around six million dead Parisians. They are one of the French capital's most famous tourist attractions – and undoubtedly its grisliest.
But they constitute only a small fragment of what the locals themselves call les carrières de Paris ("the mines of Paris"), a collection of tunnels and galleries up to 300 km (185 miles) long, most of which are off-limits to the public, yet eagerly explored by so-called cataphiles.
The Grand Réseau Sud ("Great Southern Network") takes up around 200 km beneath the 5th, 6th, 14th, and 15th arrondissements (administrative districts), all south of the river Seine. Smaller networks run beneath the 12th, 13th, and 16th arrondissements. How did they get there?
Paris stone and plaster of Paris
It all starts with geology. Sediments left behind by ancient seas created large deposits of limestone in the south of the city, mostly south of the Seine; and gypsum in the north, particularly in the hills of Montmartre and Ménilmontant. Highly sought after as building materials, both have been mined since Roman times.
The limestone is also known as Lutetian limestone (Lutetia is the Latin name for ancient Paris) or simply "Paris stone." It has been used for many famous Paris landmarks, including the Louvre and the grand buildings erected during Georges-Eugène Haussmann's large-scale remodelling of the city in the mid-19th century. The stone's warm, yellowish color provides visual unity and a bright elegance to the city.
The fine-powdered gypsum of northern Paris, used for making quick-setting plaster, was so famed for its quality that "plaster of Paris" is still used as a term of distinction. However, as gypsum is very soluble in water, the underground cavities left by its extraction were extremely vulnerable to collapse.

In previous centuries, a road would occasionally open up to swallow a chariot, or even a whole house would disappear down a sinkhole. In 1778, a catastrophic subsidence in Ménilmontant killed seven. That's why the Montmartre gypsum quarries were dynamited rather than just left as they were. The remaining gypsum caves were to be filled up with concrete.
The official body governing Paris down below is the Inspection Générale des Carrières (IGC), founded in the late 1770s by King Louis XVI. The IGC was tasked with mapping and, where needed, propping up the current and ancient (and sometimes forgotten) mining corridors and galleries hiding beneath Paris.
A delightful hiding place
Also around that time, the dead of Paris were getting in the way of the living. At the end of the 18th century, their final destination consisted of about 200 small cemeteries, scattered throughout the city — all bursting at the seams, so to speak. There was no room to bury the newly dead, and the previously departed were fouling up both the water and air around their respective churchyards.
Something radical had to happen. And it did. From 1785 until 1814, the smaller cemeteries were emptied of their bones, which were transported with full funerary pomp to their final resting place in the ancient limestone quarries at Tombe-Issoire. Three large and modern cemeteries were opened to receive the remains of subsequent generations of Parisians: Montparnasse, Père-Lachaise, and Passy.

The six million dead Parisians in the Catacombs, from all corners of the capital and across many centuries, together form the world's largest necropolis — their now anonymized skulls and bones methodically stacked, occasionally into whimsical patterns. The Catacombs are fashioned into a memorial to the brevity of life. The message above the entrance reads: Arrête! C'est ici l'empire de la Mort. ("Halt! This is the empire of Death.")
That has not stopped the Catacombs, accessible via a side door to a classicist building on the Avenue du Colonel Henri Rol-Tanguy, making just about every Top 20 list of things to see in Paris.
An underground economy
However, while the Catacombs certainly are the most famous part of the centuries-old network beneath Paris, and in non-pandemic times draw thousands of tourists each day, they constitute just 1.7 km (1 mile) of the 300-km (185-mile) tunneling total.
Subterranean Paris wasn't just used for mining and storing dead people. In the 17th century, Carthusian monks converted the ancient quarries under their monastery into distilleries for the green or yellow liqueur that still carries their name, chartreuse.
Because the mines generally keep a constant cool temperature of around 15° C (60° F), they were also ideal for brewing beer, as happened on a large scale from the end of the 17th century until well into the 20th century. Several caves were dug especially for establishing breweries, and not just because of the ambient temperature: going underground allowed brewers to remain close to their customers without having to pay a premium for real estate up top.

At the end of the 19th century, the underground breweries of the 14th arrondissement alone produced more than a million hectoliters (22 million gallons) per year. One of the most famous of Paris' underground breweries, Dumesnil, stayed in operation until the late 1960s.
In that decade, the network of corridors and galleries south of the Seine, long since abandoned by miners, became the unofficial playground for the young people of Paris. They explored the fantastical world beneath their feet, in some cases via entry points located in their very schools. Fascinated, these cataphiles ("catacomb lovers") read up on old books, explored the subterranean labyrinth, and drew up schematics that were passed around among fellow initiates as reverently as treasure maps.
As Robert Macfarlane writes in Underland, Paris-beneath-their-feet became "a place where people might slip into different identities, assume new ways of being and relating, become fluid and wild in ways that are constrained on the surface."
Some larger caves turned into notorious party zones: a 7-meter-tall gallery below the Val-de-Grâce hospital is widely known as "Salle Z." Over the last few decades, various other locations in subterranean Paris have hosted jazz and rock concerts and rave parties — like no other city, Paris really has an "underground music scene."

Cataphiles vs. cataphobes
With popularity came increased reports of nuisance and crime — the tunnels provided easy access to telephone cables, which were stolen for the resale value of their copper.
The general public's "discovery" of the underground network led the city of Paris to officially interdict all access by non-authorized persons. That decree dates back to 1955, but the "underground police" have an understanding with seasoned cataphiles. Their main targets are so-called tourists, who by their lack of knowledge expose themselves to risk of injuries or worse, and degrade their surroundings, often leaving loads of litter in their wake.
The understanding does not extend to the IGC. Unlike in the 19th century, when weak cavities were shored up by purpose-built pillars, the policy now is to inject concrete to fill up endangered spaces — thus progressively blocking off parts of the network. That procedure has also been used to separate the Catacombs to prevent "infiltration" of the site by cataphiles.

The cataphiles, however, are fighting back. In a game of cat and mouse with the authorities, they are reopening blocked passages and creating chatières ("cat flaps") through which they can squeeze into chambers no longer accessible via other underground corridors.
Catacomb climate control
Alone against the unstoppable tide of concrete, the amateurs of Underground Paris would be helpless. But the fight against climate change may turn the subterranean labyrinths from a liability into an asset — and the City of Paris into an ally.
The UN's 2015 Climate Plan — concluded in Paris, by the way — requires the world to reduce greenhouse gas emissions by 75 percent by 2050. And Paris itself wants to be Europe's greenest city by 2030. More sustainable climate control of our living spaces would be a great help toward both targets. A lot of energy is spent heating houses in winter and cooling them in summer.
This is where the constant temperature of the Parisian tunnels comes in. It's not just good for brewing beer; it's a source of geothermal energy, says Fieldwork, an architectural firm based in Paris. It can be used to temper temperatures, helping to cool houses in summer and warming them in winter.
One catch for the cataphiles: it also works when the underground cavities are filled up with concrete. So perhaps one day, Paris Underground, fully filled up with concrete, will completely fall off the map, reducing the city's formerly real doppelgänger into an air conditioning unit.

Strange Maps #1083

The prevalence of allergies arising in childhood has increased over the last 50 years, with 30 percent of the human population now having some kind of atopic disease such as eczema, food allergies, or asthma. The cause of this increase is still subject to debate, though it has been associated with a number of factors, including changes to the gut microbiomes of infants.
A new study by Canadian researchers published in Cell Reports Medicine may shed further light on how these allergies develop in children by examining the contents of their first diaper.
The things you do for science
The research team examined the first stool of 100 infants from the CHILD Cohort Study. The first stool of an infant is a thick, green, horrid-looking substance called meconium. It consists of various things that the infant ingests during the second half of gestation. Additionally, it provides not only a snapshot of what the infant was exposed to during that time, but it also reveals what the food sources will be for the initial gut bacteria that colonize the baby's digestive tract.
The content of the meconium was examined and found to contain such varied elements as amino acids, lipids, carbohydrates, and myriad other substances.
A graph of the comparative, summed abundance of different elements in a metabolic pathway after scaling to median abundance of each metabolite. The blue figures are those children without atopy, the yellow ones show the data for those with an atopic condition. Petersen et al.
The authors fed this information into an algorithm that used this data, along with the identities of the bacteria present as well as the baby's overall health, to predict which infants would go on to develop allergies within one year. The algorithm got it right 76 percent of the time.
A way to prevent childhood allergies?
Infants whose meconium had a less diverse metabolic niche the initial microbes to settle in the gut were at the highest risk of developing allergies a year later. Many of these elements were associated with the presence or absence of different bacterial groups in the digestive system of the child, which play an increasingly appreciated role in our overall health and development. The findings were summarized by senior co-author Dr. Brett Finlay:
"Our analysis revealed that newborns who developed allergic sensitization by one year of age had significantly less 'rich' meconium at birth, compared to those who didn't develop allergic sensitization."
The findings could be used to help understand how allergies form and even how to prevent them. Co-author Dr. Stuart Turvey commented on this possibility:
"We know that children with allergies are at the highest risk of also developing asthma. Now we have an opportunity to identify at-risk infants who could benefit from early interventions before they even begin to show signs and symptoms of allergies or asthma later in life."
A model for early childhood allergies
Petersen et al.
As shown above, the authors constructed a model of how they believe metabolites and bacterial diversity help prevent allergies. Increased diversity of metabolic products in the meconium encourage the development of "healthy" families of bacteria, like Peptostreptococcaceae, which in turn promote the development of a healthy and diverse gut microbiome. Ultimately, such diversity decreases the likelihood that a child will develop allergies.
