Was the climate crisis inevitable? For the Financial Times, 13 September 2019

Everything living is dying out. A 2014 analysis of 3,000 species, confirmed by recent studies, reveals that half of all wild animals have been lost since 1970. The Amazon is burning, as is the Arctic.

An excess of carbon dioxide in the atmosphere, meanwhile, has not only played havoc with the climate but also reduced the nutrient value of plants by about 30 per cent since the 1950s.

And we’re running out of soil. In the US, it’s eroding 10 times faster than it’s being replaced. In China and India, the erosion is more than three times as bad. Five years ago, the UN Food and Agriculture Organization claimed we had fewer than 60 years of harvests left if soil degradation continued at its current rate.

Why have we waited until we are one generation away from Armageddon before taking such problems seriously?

A few suggestions: first, the environment is far too complicated to talk about — at least on the tangled information networks we have constructed for ourselves.

Second, we’re lazy and we’re greedy, like every other living thing on the planet — though because most of us co-operate with each other, we are arguably the least greedy and least lazy animals around.

Where we fall down is in our tendency to freeload on our future selves. “Discounting the future” is one of our worst habits, and one that in large part explains why we leave even important, life-and-death actions to the last minute.

Here’s a third reason why we’re dealing so late with climate change. It’s the weirdest, and maybe the most important of the three. It’s that we know we are going to die.

Thinking about environmental threats reminds us of our own mortality, and death is a prospect so appalling we’ll do anything — anything — to stop thinking about it.

“I used to wonder how people could stand the really demonic activity of working behind those hellish ranges in hotel kitchens, the frantic whirl of waiting on a dozen tables at one time,” wrote Ernest Becker in his Pulitzer-winning meditation The Denial of Death in 1973.

“The answer is so simple that it eludes us: the craziness of these activities is exactly that of the human condition. They are ‘right’ for us because the alternative is natural desperation.”

Psychologists inspired by Becker have run experiments to suggest it’s the terror of death that motivates consciousness and all its accomplishments. “It raised the pyramids in Egypt and razed the Twin Towers in Manhattan,” is the memorable judgment of the authors of 2015’s best-selling book The Worm at the Core.

This hardly sounds like good news. But it may offer us, if not a solution to the current crisis, at least a better, healthier and more positive way of approaching it.

No coping mechanism is infallible. We may be profoundly unwilling to contemplate our mortality, and to face up to the slow-burn, long-term threats to our existence, but that anxiety can’t ultimately be denied. Our response is to bundle it into catastrophes — in effect to construe the world in terms of crises to make everyday existence bearable.

Even positive visions of the future assume the necessity for cataclysmic change: why else do we fetishise “disruption”? “The concept of progress is to be grounded in the idea of the catastrophe,” as the German philosopher Walter Benjamin put it.

Yes, we could have addressed climate change much more easily in the 1970s, when the crisis wasn’t so urgent. But the fact is, we’re built for urgent action. A flood. A drought. A famine. We know where we are in a catastrophe. It may be that our best is yet to come.

Will our best be enough? Will we move quickly and coherently enough to save ourselves from the catastrophes attendant on massive climate change? That’s a hard question to answer.

The earliest serious attempts at modelling human futures were horrific. One commentator summed up Thomas Malthus’s famous 1798 Essay on the Principle of Population as “150 pages of excruciatingly detailed travellers’ accounts and histories . . . of bestial life, sickness, weakness, poor food, lack of ability to care for young, scant resources, famine, infanticide, war, massacre, plunder, slavery, cold, hunger, disease, epidemics, plague, and abortion.”

Malthus, an English cleric driven up the wall by positive Enlightenment thinkers such as Godwin and Condorcet, set out to remind everybody that people were animals. Like animals, their populations were bound eventually to exceed the available food supply. It didn’t matter that they dressed nicely or wrote poetry. If they overbred, they would starve.

We’ve been eluding this Malthusian trap for centuries, by bolting together one cultural innovation after another. No bread? Grow soy. No fish? Breed insects. Eventually, on a finite planet, Malthus will have his revenge — but when?

The energy thinker Vaclav Smil’s forthcoming book Growth studies the growth patterns of everything from microorganisms to mammals to entire civilisations. But the Czech-Canadian academic is chary about breaking anything as complicated as humanity down to a single metric.

“In the mid-1980s,” he recalls, “people used to ask me, when would the Chinese environment finally collapse? I was writing about this topic early on, and the point is, it was never going to collapse. Or it’s constantly collapsing, and they’re constantly fixing parts of it.”

Every major city in China has clean water and improving air quality, according to Smil. A few years ago people were choking on the smog.

“It’s the same thing with the planet,” he says. “Thirty years ago in Europe, the number-one problem wasn’t global warming, it was acid rain. Nobody mentions acid rain today because we desulphurised our coal-fired power plants and supplanted coal with natural gas. The world’s getting better and worse at the same time.”

Smil blames the cult of economics for the way we’ve been sitting on our hands while the planet heats up. The fundamental problem is that economics has become so divorced from fundamental reality,” he says.

“We have to eat, we have to put on a shirt and shoes, our whole lives are governed by the laws that govern the flows of energy and materials. In economics, though, everything is reduced to money, which is only a very imperfect measure of those flows. Until economics returns to the physical rules of human existence, we’ll always be floating in the sky and totally detached from reality.”

Nevertheless, Smil thinks we’d be better off planning for a good life in the here and now, and this entails pulling back from our current levels of consumption.

“But we’re not that stupid,” he says, “and we may have this taken care of by people’s own decision making. As they get richer, people find that children are very expensive, and children have been disappearing everywhere. There is not a single European country now in which fertility will be above replacement level. And even India is now close to the replacement rate of 2.1 children per family.”

So are we out of the tunnel, or at the end of the line? The brutal truth is, we’ll probably never know. We’re not equipped to know. We’re too anxious, too terrified, too greedy for the sort of certainty a complex environment is simply not going to provide.

Now that we’ve spotted this catastrophe looming over our heads, it’s with us for good. No one’s ever going to be able to say that it’s truly gone away. As Benjamin tersely concluded, “That things ‘just go on’ is the catastrophe.”

Turning over new leaves

Contemplating Trees at Fondation Cartier, Paris for the Financial Times, 1 August 2019

Trees, a group show at the Fondation Cartier in Paris featuring artists, botanists and philosophers, screams personality — by which I mean eccentricity, thought and argument. Appropriately, it’s an exhibition that lives and breathes. I hated some of it and walked out of the gallery grinning from ear to ear. It absolutely does its job: it makes trees treeish again.

The French state’s funding for the arts is generous in quantity but conservative in taste. It doesn’t fund the Fondation Cartier, leaving it free to be playful — to hang so-called “outsider” and indigenous artists alongside established names; to work with artists in the long term, developing and acquiring pieces as collaborations grow. In other words, Paris’s first private foundation for contemporary art is free to behave as a private patron should and to learn on the job.

Trees is the latest in a line of exhibitions conceived by the Fondation Cartier that seek to decentre humans’ view of ourselves as overlords of creation. In 2016, The Great Animal Orchestra exhibition (which visits London in October) sought to establish common intellectual ground between species. Trees goes further, seeking a rapprochement between two kingdoms, the animals and the plants.

Trees are weirdly hard to see because they hide in plain sight. “The tree is the chair on which we sit, the table we use to write, it is our cupboards, our furniture, but also our most ordinary tools,” as Parisian philosopher Emanuele Coccia writes in the exhibition catalogue.

Tree-blindness is made worse by a western intellectual inheritance. When Aristotle asserted in his De plantis that vegetable life is insensate, he was going against Plato, Anaxagoras, Democritus and Empedocles. And he was wrong: plants detect and react to temperature, humidity, air pressure, vibration, sound, touch, trauma and chemical information that we have no short names for. They respond to these sensations as quickly as any animal. They are not less than animals, but they are radically, mind-bendingly different.

A life among trees does things to the eye. Perspective is not much help in reading a treescape, while pattern recognition is vital. Work here by Kalepi, Joseca and Ehuana Yaira, Yanomami artists from the Amazon rainforest, explores the architectonic quality of trees, expressing them as entire bodies rather than (as the western eye prefers) complex assortments of twigs and leaves. The Paraguayan artists of the Gran Chaco region included here, meanwhile, express their forest home more through typology than through aesthetics. Theirs is a forest as well-stocked and well-ordered as a supermarket. Count all the little animals and plants laid out in rows: this is not a wilderness but a tally of self-renewing plenty. The general lesson seems to be that a forest is an environment that’s easier to read for what it contains than to swallow in one gulp.

Drawings and diagrams by contemporary botanist Francis Hallé honour natural history, a European tradition in which aesthetic knowledge and scientific knowledge run parallel. Twentieth-century laboratory-based science finds its way on to Fabrice Hyber’s huge canvases — like wall-sized notebook pages annotated with multicoloured scribbles, graphs, colour wheels and wave forms. In each, Hyber reduces the trees to a single trunk, or a trunk and a branch: a world of abstractions and generalis­ations. Cesare Leonardi’s meticulous drawings reveal the architectural potential of trees — a potential mischievously misappropriated in Peruvian photo­grapher Sebastian Mejía’s pictures of trees strained through fence wire, incorporated into walls or otherwise appropriated by the unliving city.

Some works here protest against the world’s breakneck deforestation. Thijs Biersteker, in collaboration with botanist Stefano Mancuso, offers a salve, wiring two trees in the Fondation’s extensive garden to scientific visualisations to help us empathise with what trees are sensing in real time. (This is more than a rhetorical flourish: the sense data that the piece collects are being corroborated and fed into scientific research, in a work that fulfils a dual artistic and scientific function.)

The lion’s share of the show is given over to Brazilian artist Luiz Zerbini, whose muted, simple monotypes and huge, complex, colourful canvases surround a table herbarium and a tree. The paintings are an Anthropocene jungle of sorts in which urban and natural forms hide in plain sight within a fiercely perpectiveless, rectilinear grid. Give your eyes time to adjust, and you find yourself in a city/forest of the future, where nature is exploited but not exhausted, and beauty and utility coexist.

These canvases suggest that we humans, having crafted our way out of the trees and developed those crafts on an industrial scale, can perhaps learn an even neater trick and make the whole human adventure last beyond this current, rapine moment

I came out of this show happy. I wasn’t just enthused. I’d been converted.

Just a nuclear-powered dinosaur

Pondering the science of Godzilla for New Scientist, 12 June 2019

FOR Japanese children, Godzilla is the ultimate scary adult: fierce, honourable, clumsy and a bit out of control. For their grandparents, he’s the irradiated embodiment of wartime tragedy, a bad memory come to life. For the rest of us, I suppose, he’s “just” a nuclear-powered dinosaur.

Godzilla is also a pay cheque. Films featuring the epic creature, almost all by the Japanese studio Toho, have been produced since 1954, a cinematic franchise record. The current release, Godzilla: King of the monsters, is the 35th, and the third to be produced entirely within the Hollywood system.

Its human stars play the shattered Russell family. Millie Bobby Brown from TV hit Stranger Things is Madison, whose brother Andrew was killed during a 2014 kaiju (monster) attack on San Francisco. Her dad Mark is literally living with wolves; her mum Emma prefers kaiju to people.

Terroristic eco-warriors are out to awaken Godzilla’s subterranean cousins in an effort to bring the planet “back into balance” – and Emma is inclined to help them. Newsreel images of ruined San Francisco make her point: in five short years it has turned to jungle, accelerated by ionising radiation spilling from Godzilla’s insides.

Why do movies, stretching back to the giant ants of Them!, assume that excess radiation promotes growth? The evidence has always pointed the other way. Ionising radiation weakens and breaks up DNA, damaging cells enough to kill them, or cause them to mutate in ways that, somehow or other, lead to the grave. In humans, epidemiological studies show that even low doses of radiation increase the risk of cancer.

Still, human nature being what it is, whenever a new kind of ray is detected, we speculate about its magical properties. Radium, a radioactive metal, was discovered by Marie and Pierre Curie in 1898, and though it eventually killed her, it still found its way into the food chain thanks to products like Hippman-Blach bakery’s Radium Bread (made with radium-laced water, which was supposed to cure everything from arthritis to impotence to wrinkles).

Is there more to this accelerated-growth idea than magical thinking? “Hormesis” is the controversial notion that things that are dangerous in high doses might be beneficial to human health at lower levels. Some lab studies have shown the effect in action. Whether there is radiation hormesis, however, is a big question – and a timely one.

China’s space programme has studied the ability of plants to develop and thrive in conditions of microgravity and exposure to cosmic radiation in space. Since 1987, 66 mutant varieties have been cultivated through its space-breeding efforts.

So far, so workaday: “atomic gardening” has been around since the 1950s, exposing plants to radioactive sources (typically cobalt-60) to generate mutations, and over 2000 new varieties of agriculturally useful plants have been created this way.

The Chinese results, however, are a bit weird. Plants positively mutated during space flight have grown faster than their irradiated Earth-grown counterparts. Space-bred mutations do better than their “atomically gardened” controls, and no one is sure why.

Is there something magical about cosmic rays? Probably not, though if I were Godzilla (traditionally Earth’s first line of defence against alien attack) I would watch my back.

“And it will no longer be necessary to ransack the earth…”

Visiting Raw Materials: Plastics at the Nunnery Gallery, Bow Arts, for the Spectator, 1 June 2019

Plastics — even venerable, historically eloquent plastics — hardly draw the eye. As this show’s insightful accompanying publication (a snip at £3) would have it, ‘Plastics have no intrinsic form or texture, thus they are not materials that can be true to themselves.’ They exist within inverted commas. They can be shell-like, horn-like, stony, metallic — they do not really exist on their own behalf.

Mind you, the first vitrine in Raw Materials: Plastics at the Nunnery Gallery in east London contains an object of rare beauty: a small, mottled, crazed, discoloured sphere that looks for all the world like the planet Venus, reduced to handy scale.

It’s a billiard ball, made of the first plastic: cellulose nitrate. Its manufacture had been keenly anticipated. In the US, a $10,000 prize had been offered for anything that could replace ivory in the manufacture of billiard balls (and no wonder: a single tusk yields only three balls).

Under various brand names (Celluloid, Parkesine, Xylonite), and in spite of its tendency to catch fire (colliding snooker balls would occasionally explode), cellulose nitrate saved the elephant. And not just the elephant: plastics pioneer John Wesley Hyatt reckoned that ‘Celluloid [has] given the elephant, the tortoise, and the coral insect a respite in their native haunts; and it will no longer be necessary to ransack the earth in pursuit of substances which are constantly growing scarcer.’

The whole point of plastic is that it has no characteristics of its own, only properties engineered for specific uses. Cheaper than jade. Less brittle than bone. It’s the natural material of the future, always more becoming than being. Hence the names: Xylonite. Bexoid. Halex. Lactoid.

Unable to nail the material in words, one writes instead about its history, sociology, industrial archaeology or ecological impact. On remote islands in the Pacific, thousands of albatross chicks are starving because the parents mistake floating plastic debris for food. Stories like this conjure up a vision of vast islands of discarded plastic coagulating in the Pacific Ocean, but there aren’t any. Instead, plastics eventually fragment into ever smaller pieces that are ingested by marine animals and carried to the sea bottom. In the Mariana Trench, all crustaceans tested had plastics in their guts. So plastics rise and fall through the food chain, creating havoc as they go — a bitter irony for a material that saved the elephant and the turtle, made fresh food conveyable and modern medicine possible, and all for less than 15 per cent of global oil consumption.

What can be gained from looking at the stuff itself? Raw Materials: Plastics transcends the limitations of its material by means of a good story. The first plastics were made in the Lea Valley, not from crude oil, but from plant materials, in a risky, artisanal fashion that bore, for a while, the hallmarks of older crafts including baking, woodcutting and metalwork. Fast-forward 140 years or so and, under the umbrella term ‘bioplastics’, plant-based and biodegradable synthetic products promise to turn the wheel of development full circle, returning plastics to their organic roots. (Designer Peter Marigold’s FORMCard plastic, used here in an excellent school art project, is a starch-based bioplastic made from potato skins.) Then, perhaps, we can break the bind in which we currently find ourselves: the one in which we’re poisoning the planet with plastic in our efforts not to further despoil it.

This is the third and for my money the most ambitious of the gallery’s ongoing series of small, thoughtful exhibitions about the materials, processes and industries that have shaped London’s Lea Valley. (Raw Materials: Wood ran in 2017; Raw Materials: Textiles last year.) The show is more chronicle than catalogue, but the art, scant as it is, punches above its weight.

I was struck, in particular, by France Scott’s ‘PHX [X is for Xylonite]’, a 13-minute collage of photogrammetry, laser scanning and 16mm film. It ought, by all logic, to be a complete mess and I still haven’t been able to work out why it’s so compelling. Is it because digital artefacts, like their plastic forebears, are themselves prisoners of contingency, aping the forms of others while stubbornly refusing to acquire forms of their own?

Bringing London’s buried rivers to light

Could things have turned out differently for London’s lost rivers? Probably not, but it’s fun to tinker. In 1992 a group of artist-activists called Platform set up a mock Effra Redevelopment Agency to consult the residents of Brixton about their plans to open up the local river. A sylvan wonderland awaited those who didn’t mind losing their houses.

Exploring London’s hidden rivers for the Financial Times, 8 June 2019

The most blatantly artificial landscape in Europe

Why do the Lakes generate such strong feeling? Because they’re endangered? Or because they’re already spoiled? Spoiled how? By afforestation, by sheep, by the clumsy application of preservationist aspic? They’re not what they were, on this we can agree. But what were they? At Windermere Jetty, alongside elements of familiar Lakeland lore — steam kettles, childhood boating holidays, Beatrix Potter’s rowing boat mounted on one wall — other, more disconcerting aspects of the region are revealed: the Lakes as mining region, as testbed for new technologies, as strenuously guarded zone of wartime production…

Slightly fleshy, slightly scabby, cast adrift

Exploring Matthew Day Jackson’s show Pathetic Fallacy at Hauser & Wirth Somerset for the Times Literary Supplement, 26 February 2019

The New York-based artist Matthew Day Jackson takes mixed media seriously. Behind the techniques and materials, the molten lead and the axe handles, the T-shirts and laser-etched Formica, Jackson’s aesthetic sees the world not as a continuum but as a mass of odd juxtapositions. Since his first big solo show in 2004, he has intertwined the grotesque and the beautiful. Every ten years, he paints a picture of himself as a corpse, but the majority of his work is mischievous, holding the autobiographical and the cerebral in an uneasy balance.

Hauser and Wirth, an international gallery with a strong educational remit, regularly brings its spikier artists to its property in Bruton, Somerset, to stay, work and reflect. The residencies come without strings, there are no prescribed outcomes, and one suspects there’s a certain mischief in who gets chosen. First to arrive, in 2014, was the (intermittently scary) video artist Pipilotti Rist. Seduced by her surroundings, she came up with sensuously observed close-ups of bodies and leaves in intimate proximity. Nothing wrong with that, of course. But it’s a risk for the gallery, and a challenge for the artists who stay here, that the landscape round about is so ridiculously seductive.

Showing next door to Matthew Day Jackson, Eve, an exhibition of paintings by the Somerset-based artist Catherine Goodman, is unashamedly paradisal. Even its edge of Freudian melancholy proves heartwarming in the end.

What on earth will Jackson, a cerebral city-dwelling proponent of an aesthetic he dubs the “horriful”, do with all this serried loveliness? He says that at first he found the landscape hard to read. “It’s more like urban space”, he says. “Everywhere you look, you can trace how humans have engaged with this place.” He can’t get over the time-worn depth of the lanes here. There’s no equivalent back home: “Maybe in Oregon and Wyoming, you can find tracks still rutted by wagon wheels”.

Predictably, for an artist who’s spent his career mapping the failures of American utopianism, Jackson has responded to the beauty around him by mourning its passing. His Solipsist collage-paintings of silk-screened Formica zoom out to encompass large swathes of the planet. Seen from various orbital viewpoints (the images are based on photographs taken by NASA astronauts) four elements emerge. Mine workings strip the Earth back to, well, its earth. The hopelessly polluted Ganges and the virtually vanished Ural Sea stand for water. Smoke plumes from forest fires give a shape to air. Yellowstone Lake inhabits a caldera that, if it erupted, would consume most life on Earth.

Each landscape, weirdly colourized (“Formica limits your colour palette”), laser etched with precise contours and subtle, uninterpretable boundary lines, resembles a computer-readable map. “Over” it (or, to be literal about this, embedded in it) is the flattened image of a satellite, made of cast lead.

The fact that the satellite observing the view is itself melted into the picture suggests a colossal foreshortening. There’s something suggestive of Jean Dubuffet, too, in the way the texture of the satellite is employed to convey a radical flatness. There’s no shade here, no occlusion, no hint of curvature. Human activity and human destiny are being measured and metricized to the point where even the planet has nowhere to turn.

Jackson’s flower paintings in the next room continue the theme: vases of hallucinatory Formica and fabric blooms, backlit by unearthly aurorae that may reference the tie-dye fad of the early 1970s but are more likely – given the way this show is going – something ghastly to do with nuclear testing.

The paintings work with the Astroturf floor and Jackson’s experimental, sculptural furniture to explore the idea that we only ever see things through their use. This isn’t a human foible: living things generally only sense what is relevant to their survival. So if Jackson is holding humanity to account here, it is a gentle and considered judgement. “What we most want is to feel that we exist”, he says, as we contemplate vanished seas and shredded mountain ranges. “We want not be lonely. Hence the appeal of metrics: they give us a sense of accomplishment.”

It can be a nuisance, having the artist around when you’re viewing a show. I was initially thinking about our greed and rapacity, and now, looking at these spoiled and garishly mapped earths, all I can see is our pathos: how we are polishing our rock down to the granite, just so we can glimpse ourselves in it.

Pathetic Fallacy is a well-chosen title for this show. John Ruskin coined the phrase to have a dig at the emotional falsity of poets who made clouds weep and trees groan. Jackson’s show is more in the spirit of Wordsworth’s defence of the practice, arguing that “objects . . . derive their influence not from properties inherent in them . . . but from such as are bestowed upon them by the minds of those who are conversant with or affected by these objects”.

In other words, we impose ourselves on the world because we feel we are the only meaning makers. On the way out, I pass more pictures: flattened lead satellites, cast in moulds made of corrugated cardboard, twine, sawdust, glue. This close, they appear slightly fleshy, slightly scabby, cast adrift, and travelling out into space.

A world that has run out of normal

As global temperatures rise, and the mean sea-level with them, I have been tracing the likely flood levels of the Thames Valley, to see which of my literary rivals will disappear beneath the waves first. I live on a hill, and what I’d like to say is: you’ll be stuck with me a while longer than most. But on the day I had set aside to consume David Wallace-Wells’s terrifying account of climate change and the future of our species (there isn’t one), the water supply to my block was unaccountably cut off. Failing to make a cup of tea reminded me, with some force, of what ought to be obvious: that my hill is a post-apocalyptic death-trap.

The world bacteria made

Visiting Bacterial World at the Oxford University Museum of Natural History for New Scientist, 23 November 2018

“It’s like a cheetah going after a wildebeest,” says Judith Armitage, lead scientist for Bacterial World, an exhibition at the Oxford University Museum of Natural History. She’s struggling to find a simile adequate to describe Bdellovibrio bacteriovorus, a predatory bacterium found, among other places, in the human gut. Indeed, it’s monstrously fast: capable of swimming 100 times its own body length every second.

Other bacteria are built for strength, not speed. Campylobacter jejuni, which we have to thank for most of our food poisoning, has a propeller-like flagellum geared so that it can heave its way through the thick mucus in the gut.

Armitage has put considerable effort into building a tiny exhibition that gives bacteria their due as the foundational components of living systems –and all I can think about is food poisoning. “Well that’s quorum sensing, isn’t it?” says Armitage, playing along. “After 24 hours or so biding their time, they decide there’s enough of them they can make you throw up.”

Above our heads hangs artist Luke Jerram’s gigantic inflatable E. coli, seen floating over visitors at the first New Scientist Live festival in 2016. It seems an altogether more sinister presence in Oxford’s Museum of Natural History: the alien overseer of a building so exuberantly Gothic (built in 1860, just in time for the famous evolution debate between Thomas Huxley and “Soapy Sam” Wilberforce, the Bishop of Oxford) that it appears more grown than made.

Armed with just 55 exhibits, from the Wellcome Collection, the Pitt Rivers Museum and the Natural History Museum in London, Armitage has managed to squeeze 3.8 billion years of history along a narrow balcony just under the museum’s glass roof. Our journey is two-fold: from the very big to the very small, and from the beginnings of life on Earth to its likely future.

Towering stromatolites, the earliest fossil evidence of life on Earth, reveal the action of countless anaerobic bacteria whose trick of splitting water would result, a million years later, in an extremely rusty planet filling up with toxic oxygen. To survive, let alone thrive, in the ghastly conditions ushered in by the Great Oxygenation Event required bacterial adaptations on which all living things today depend. For example, Paenibacilla (pictured) promote crop growth, and symbiotic bacteria of the genus Rhizobium pack essential hard-to-get at iron into our vegetables. Cellular adaptations defend against caustic oxygen, and have, incidentally, thrown up all manner of unforeseen by-products, including the bioluminescence of certain fish.

As multicellular organisms, we owe the very structure of our cells to an act of bacterial symbiosis. Our biosphere is shaped to meet the needs of ubiquitous bacteria like Wolbachia, without which some species of environmentally essential insect cannot reproduce, or even survive.

Naturally, we humans have tried to muscle in on this story. For a while we’ve been able to harness some bacteria to fight off others, thereby ridding ourselves of disease. But Armitage fears the antibiotic era was just a blip. “New antimicrobials are too expensive to develop,” she observes. “Once they’re shown to work they’ll be kept on the shelf waiting for the microbial apocalypse.”

But look on the bright side. At least once the great Throwing Up is over and the human population shrinks to a disease-racked minimum, the bacteria released from our ballooning guts can get back to what they’re good at: creating vibrant ecosystems out of random raw material. “Bacteria will eat all the plastic.” Of this Armitage is certain. “But,” she adds, “it takes time for metabolic cascades to evolve. We’ll probably not be around to see it happen.”

On the way out, my eye is caught by another artwork:  uneasy and delicate pieces of crochet by Elin Thomas depicting colonies of bacteria. The original colonies were grown on personal objects: a key, a gold wedding ring; a wooden pencil. A worn sock.

Microbial World is a tremendous exhibition, punching way above its tiny weight. It doesn’t half put you in your place, though.

Edward Burtynsky: Fossil futures

An overview of The Anthropocene Project for New Scientist, 10 October 2018

THE lasting geological impact of our species is clearly visible within the galleries of this potash mine in Russia’s Ural mountains. The Urals contain one of the largest deposits in the world of this salt, one of the most widely used fertilisers. Mining has left behind vast subterranean galleries, their walls machine-carved with enormous ammonite-like whorls.

The Canadian photographer and artist Edward Burtynsky took this photograph for The Anthropocene Project, a collaborative chronicle of geologically significant human activity such as extraction, urbanisation and deforestation. Works from the project are on display at the Art Gallery of Ontario and the National Gallery of Canada, while this image and other photographs feature in Burtynsky’s exhibition The Human Signature, at London’s Flowers Gallery, to 24 November.

This September also saw the release of a documentary film, Anthropocene: The human epoch, and a book of colour photographs by Burtynsky, which includes new writing from author and poet Margaret Atwood.

Through publications, films and immersive media, Burtynksy and his Anthropocene Project collaborators – filmmakers Jennifer Baichwal and Nicholas de Pencier – convey the unsettling visual reality of resource depletion and extinction: how our planet’s surface is being scarred, ground and shovelled into abstract, almost painterly forms.

The effects of mining, in particular, are irreversible. While animal burrows reach a few metres at most, humans carve out networks that can descend several kilometres, below the reach of erosion. They are likely to survive, at least in trace form, for millions or even billions of years.

There is an eerie poetry to this: burrows found in 500-million-year-old sediment tipped off geologists to the massive diversification of animal forms known as the Cambrian explosion. Will our own gargantuan earthworks commemorate more than just a mass extinction event?
