Extraction/Abstraction by Edward Burtynsky @ the Saatchi Gallery

This is an epic, awesome exhibition, maybe the best exhibition currently on in London, certainly the most visually stunning one I’ve been to this year. It is not just a ‘photography exhibition’ but a display of masterpieces by a photographer of genius.

Largest ever Burtynsky exhibition

It is the largest exhibition ever mounted of the work of world-renowned photographic artist, Edward Burtynsky. Born in Canada in 1955, Burtynsky has spent over 40 years documenting the generally ruinous impact of human industry around the planet, in series of projects focused on environment-changing human activities such as mining, oil production, agriculture and so on.

It’s a big exhibition in every sense. They’ve brought together 94 of Burtynsky’s large-format photographs and the thing to grasp is that his photos are not just big, they’re massive, huge, enormous. You can only fit so many of these monsters into one space so the show is spread across 6 big galleries over two floors.

In addition to the 80 or so enormous digital prints there are 13 high-resolution murals i.e. photos blown up to cover entire walls, which overawe you with their scale and then draw you in to study the incredibly fine digital detailing.

Factual captions

Each photo comes with a fact-packed wall label which explains the human activity we’re looking at. Often curatorial wall labels are barely worth reading or contain tiresome lectures from the curators about the tired old subjects of race or gender. By complete contrast, the wall labels in this exhibition are head and shoulders above the usual ruck because every one tells a fascinating story and gives you the hard facts without moralising. The facts are enough.

So, for example, the piece below is an aerial photo taken just outside the Atlantic port city of Cadiz in south-west Spain. The city is surrounded by salt marshes which once brought prosperity to the region by making it a major producer of sea salt. Snaking through the salt marshes are streams of turquoise sea water. Around these are a complex series of ridges which divide the marshes into ‘fields’ where salt can be harvested, some of which date from 1,200 BC. At the start of the 20th century some 160 artisanal sea salt producers worked these salt pans, now it’s down to just a handful.

Extraction and the environment

It is a highly environmentalist exhibition (where environmentalist is defined as ‘concerned with or advocating the protection of the environment.’) Almost all the pieces show the catastrophic impact of human activity on the natural world, each image accompanied by fascinating, often profoundly dismaying information. Because every exhibition needs organising principles, the pictures, and so the accompanying information captions, are divided into themes, being:

  • Agriculture
  • Extraction
  • Manufacturing and infrastructure
  • Waste

The facts described in the picture captions are often mind-boggling. For example, there’s a photo of a vast array of plastic greenhouses in Ziway, Ethiopia, which covers an enormous 450 hectares in total. Up to 4 million roses are cut and shipped each day from here, almost all destined for the European market, where unknowing consumers buy bunches of Ethiopian-grown roses for their impressionable partners, both heedless of the enormous environmental cost behind every one of them.

Or take the wall label introducing the gallery devoted to Agriculture. This tells us that there are over 8 billion people on the planet and we all need to eat, preferably several meals a day. Approximately 75% of the global population eats meat, which corresponds to roughly 23 billion animals kept as livestock. Adding up all the people, livestock and, of course, pets, global agriculture must feed over 31 billion hungry creatures every day.

Creating enough agricultural land to cater to this vast, relentless need is the cause of endless environmental catastrophe:

  • mass cutting down of ancient forests
  • devastation of biodiversity
  • depletion of one-off resources such as aquifers
  • leaching of toxic pesticides and fertilisers into the water supplies
  • constant emission of greenhouse gases at every step of production, processing and transport

Abstraction

So far, so environmentalist. But there’s another whole layer to the exhibition and to Burtynsky’s practice, which is indicated in the exhibition title (Extraction/Abstraction) and underpins much of his work. This is that, from the early days of his career he came to realise that large-scale photographs of landscapes, taken from high vantage points like mountains or from helicopters or drones, often look very like the abstract art produced by the various movements of abstract art in the twentieth century, from Paul Klee teaching at the Bauhaus in the 1920s to Jackson Pollock getting drunk in New Jersey in the 1950s.

The curators have some characteristically clear and intelligent things to say about this:

Abstract art emerged in the early twentieth century as a radical break with the old ways of making pictures. Rather than depicting recognisable figures, objects or landscapes, abstract painting explores form, texture and colour for their own sakes.

Over the same period industrial agriculture, mass production, surface mining and the internal combustion engine also emerged, changing our way of life forever. Today technology is rapidly propelling us into the future in every sector…

While modern artists invented new expressive and emotional languages, modern engineers, technicians and industrialists were developing a new reality, divorced from the ancient ways of being, alien to the natural world and wholly unsustainable.

Among the appealing elements of Burtynsky’s thrilling photos is his invocation of and toying with the conventions of abstract art. Many of his photos can be appreciated for their abstract beauty first, before we delve further into the ruined landscapes and human toil which lies behind them.

And it’s true. Look at the photos I’ve included so far in this review and you can see how the vivid, colourful landscapes often approach or fully appear as abstract designs. To be honest, this turns out to be more true of the first floor of works, less true of the second floor which depicts more ‘realistic’ scenes, such as vast waste mountains in Nigeria, the world’s biggest dump of used tyres in America, dehumanisingly vast factories in China and Bangladesh, and so on.

So this abstract aspect is not to be found in all of his works, but the abstract qualities which are to the fore in the early rooms continue to haunt the later, more realistic works, appearing round their edges so to speak, hinting at the deeper, unexpressed patterns and subtle regularities which emerge from the chaos of human activity.

‘In the Wake of Progress’

In between the two floors of big stunning photographs, on a mezzanine floor, is a large room which has been blacked out in order to host what the curators call an augmented reality (AR) experience but you and I might think of as an old-fashioned film, the gimmick being that it is divided into three separate screens alongside each other, sometimes depicting the same subject, sometimes showing different angles of the same thing, sometimes changing and moving on before the other two screens can catch up, a dynamic triptych. It is a musical and rhythmic way of presenting moving images.

The film is titled ‘In the Wake of Progress’ and, as the name suggests, shows the vast wake of destruction and dehumanisation left by the unstoppable exploitation of the planet’s natural resources. Unusually for me, I sat and watched the entire half-hour thing through in its entirety. It is an absolutely stunning, commentary-free, wordless series of beautifully shot sequences depicting the same kinds of scenes we’ve seen in the photos, devastation, waste and pollution everywhere.

It starts with four or five minutes of a static shot in an unspoiled northern forest (as captured in the photo above), all moss-covered trees and hovering insects, calming the viewer and lulling us into a false sense of security (it was actually shot in a place called Avatar Grove on Vancouver island, British Columbia, Canada).

But then the destruction commences, with shots of forests much like this being logged and reduced to muddy bare hillsides; vast numbers of logs being floated downriver to huge lumber yards; and on to open cast mining; dynamiting rocks in quarries; oil spills rainbowing rivers; vast dumps of rusting oil cans, plastic phones, used tyres; terrifyingly huge inhuman factories; oil production; vast megacities criss-crossed by urban freeways choked with traffic – a bombardment of images of human destructiveness.

The promotional material makes much of the fact that the film and music were created with the help of ‘legendary’ Canadian music producer Bob Ezrin. I thought this phrasing was a tad counter-productive and made it sound like a self-congratulatory speech at the Oscars (‘And now ladies and gentleman,  the one and only, the legendary music producer, Boooob Ezrin!‘). The wall label also explains that the haunting wordless vocals which thread through the soundtrack are by ‘award-winning Cree Métis artist iskwē’, which is interesting enough, I suppose.

But the single most obvious thing about ‘In the Wake of Progress’ is how very similar it is, in visual themes and in even the repetitive, arpeggio-heavy soundtrack, to the great 1982 film Koyaanisqatsi, by ‘legendary’ director Godfrey Reggio, with music by ‘legendary’ minimalist composer Philip Glass. All it needed was the slow-motion sequence of Las Vegas casino workers and it would have become virtually the same film.

My point is nothing about plagiarism or anything like that, in fact I have two points. 1) What the similarity of both films suggest is that if you set off with the aim of depicting mankind’s destruction of the natural world, you’re going to end up shooting the same kinds of sequences (open cast mining, oil production, hyper-highways in mega-cities) i.e. there will be an inevitable sameyness about films like this because they are covering the same subject.

Secondly 2) the two films were produced and released exactly forty years apart (1982, 2022). Me and my like-minded liberal friends were obsessed with Koyaanisqatsi – I went to see it in the cinema at least five times when it came out. Being young, we thought immensely powerful cultural products like this would change the world and bring its rulers to their senses. Now, being old, I know that’s never going to happen. Films like this are nice to look at, trigger strong emotions, and change absolutely nothing.

Burtynsky the technological innovator

For photography buffs there’s a section of the show devoted to listing and explaining Burtynsky’s technical innovations. It turns out that he has not only adapted to the huge changes which have taken place in the technical side of photography over the past 40 years (the arrival of digital technology revolutionising everything) but has often been at the forefront of that innovation – working with the technical teams who accompany him on his projects to develop engineering and design solutions to the challenges of creating such huge photos, often taken from a great height.

This latter fact (height) explains the presence of not one but several drones in the display case, along with interesting explanations of how his engineers have changed and adapted them to fly stably and horizontally, while carrying ever-more powerful digital cameras.

In the photo above, on the wall on the right you can see a timeline of Burtynsky’s projects, starting with the earliest while he was still at Ryerson Polytechnic (1979 to 1981) and then listing each of his major projects and publications, year by year, with a paragraph or so detailing what technical innovations he brought to each of them.

Self overcoming

Years ago I read half a dozen books by the German philosopher Friedrich Nietzsche. I wouldn’t pretend to be any kind of expert but my understanding is that a fundamental principle of Nietzsche’s philosophy is the notion of ‘self overcoming’. It’s the idea that in order to become who you want to be, you first need to overcome who you are. In order to realise your full potential, you must consciously conquer the aspects of your character and mind which limit and hold you back.

So far, so much like a Californian self-help video. Where Nietzsche pushes on is in holding the view that most of us are held back from a full understanding of the world we live in by a whole network of conventional thinking, commonplace morality, sentimental attitudes, wishful thinking, moral cowardice and intellectual weakness. In a thousand ways we hide from the truth of who we are and what we are doing.

Nietzsche said we should face the truth about ourselves and embrace it no matter how negative and destructive it may appear. Only by embracing the totality of our real natures can we live in truth.

Well, OK, then. All the facts indicate that we are destroying the planet, wrecking every ecosystem we’ve ever encountered and exterminating our fellow life forms at an unprecedented rate – and, following Nietzsche, I think we should embrace the fact. We should fully admit to being world killers and planet destroyers. We should own it and admit to being the nature-hating, species-exterminating, habitat-trashing creatures that all the evidence suggests we are.

In my opinion most people, especially in the pampered West, live in complete denial about what monsters the human race are – as my recent reviews of modern African or Middle Eastern history show time and time again, or the situation in Ukraine or Gaza demonstrate beyond dispute – we are planet-destroying locusts but locusts with machine guns and nukes, committed to the devastation of the planet and the mass killing of our own species.

I would rather it isn’t so, but it is so and any attempt to deal with the situation must start by acknowledging this truth. This position explains why, for me, the only weak point in the exhibition was where Burtynsky, disappointingly, joined in with the chorus of trite truisms, the sentimental bromides, and the wilful optimism of the wishy-washy liberal who still has hope:

‘I have spent over 40 years bearing witness to how modern civilization has dramatically transformed our planet. At this time, the awareness of these issues presented by my large format images has never felt more urgent… I hope the exhibition experience will continue to provide inflection points for diverse conversations on these issues and move us all to a place of positive action.’

‘Diverse conversations’ – does he really think ‘diverse conversations’, at dinner parties, down the pub or on social media, even at high-level gatherings like the COP conferences, are going to make a blind bit of difference to anything, because they absolutely aren’t and it’s disappointing that an artist who’s made such original art out of the disaster, still holds such weakly conventional opinions about it.

‘Add your thoughts to the conversation’

In the spirit of sentimental optimism which I’ve just explained why I despise, the exhibition contains two big blackboards with cups of white chalk sticks, and encourages us to write uplifting messages on the boards and ‘add your thoughts to the conversation’. Examples included: ‘Turn your phone off now’, ‘It’s easy to be green,’ ‘Be nice to the environment’ and other such gift card slogans. True to my blunt Nietzschean approach, I wrote ‘Exterminate all the brutes’.

To anybody who doesn’t get the reference, these are the words scrawled at the end of the high-minded missionary pamphlet written by the deranged colonial ivory agent, Kurtz, in Joseph Conrad’s novella ‘Heart of Darkness’. I wrote it in a spirit of Swiftian satire, for in the novel Kurtz has been driven completely mad by the sub-human savagery he encountered in the heart of the Congo, which he has assimilated and then taken to a whole new level of nihilistic destructiveness. He started out with the highest aims of bringing ‘civilisation’ to the heart of Africa and ended up with a mad vision of killing every one of the local people.

Everything I’ve read about the Congo backs up Kurtz’s feelings about the human race. If in any doubt you should make a study the Rwanda genocide and its aftermath in the two Congo wars and the Great War of Africa, which, even after the loss of up to 5 million lives, in eastern Congo lingers on to this day. And what lay behind this series of disasters? Greed to rape Congo of its natural resources.

First it was white Europeans enslaving, mutilating and massacring Africans in order to extract Congo’s vast rubber production; but then it was Africans looting, impoverishing, massacring and murdering each other in order to loot Congo’s other, mineral, resources. The colours of the skin and the names of the rulers (Leopold, Lumumba, Mobutu, Kabila), the ideologies they used to justify themselves (Christianity, communism, pan-Africanism, capitalism), all changed with the passing decades, but one constant remained the same: the murderous, nature-killing intensity of human greed. Vast wars were fought, immense human suffering caused, and large areas of the country ravaged by man’s endless quest for the blood diamonds, copper, gold and the rare metals which the world needs to carry on its course of untrammeled consumption.

Which is why bromides like ‘Save Earth, Save Life!’, ‘Protect Our Planet, Preserve Our Future’ and ‘There is no planet B’ seem to me wholly inadequate to capture the brutal truth of the world we live in, the terrible violence man deals out to man every day (and worse to unprotected women and children), the appalling misery endured by the slaves who produce the components of our luxury goods, the daily murder of tens of millions of dumb animals so we can eat them, and the relentless degradation of every ecosystem on the planet.

Hence the saeva indignatio of my crayoned comment, scrawled across the blackboard in the same way that Kurtz, driven mad by seeing into the complete darkness of the human heart, ended his utopian pamphlet with the most nihilistic comment he could conceive of – ‘Exterminate all the brutes’ – a comment less on the natives of Congo than on the shallow, inadequate Christian ‘civilisation’ he was meant to be representing.

(The phrase saeva indignatio popped into my memory at this point and prompted me to look it up. It is Latin for ‘savage indignation’ and is a phrase used in the Latin epitaph of the great 18th century satirist Jonathan Swift, to denote his ‘intense feeling of contemptuous anger at human folly’.

So that’s what I wrote on the blackboard of this powerful, terrifying exhibition, and why – the last words of a deranged idealist, quoted to express my ‘intense feeling of contemptuous anger at human folly’.)

The merch irony

A last point about those exhibition blackboards: the way children, or those with a childlike understanding of the world, had covered them with infant-school slogans like ‘End consumerism’ and ‘Just stop buying stuff’ meant I couldn’t help laughing out loud when this breath-taking exhibition shunted me out, at the end, into the huge, clean and well-stocked Saatchi Gallery shop, a big room overflowing with classy merchandise and shiny products.

Here, as at all art exhibitions, you can find a range of posters and postcards and bags and books relating to the exhibition, which all lead up to a collectable box set of stylishly produced Burtynksy books and memorabilia. This will set back the well-heeled art fan a tidy £15,000.

As I reeled from the cognitive dissonance between everything I’d just been seeing and reading, between all those high-minded ‘green’ sentiments on the blackboards, and this riot of unashamed consumerism – a posh couple sauntered by and stopped at the pile of exhibition catalogues (a snip at £38). ‘Oh my God,’ gushed the young lady, flicking through the pictures of ruination made beautiful, ‘this would make such a fabulous coffee table book!’

And there, in a nutshell, you have it. Middle-class people queuing up to buy postcards, t-shirts, tote bags, fridge magnets, mobiles, videos and earnest books all advocating the end of the consumerism. Swift would be looking on, nodding and chuckling.

Thoughts

This is an awesome, amazing, must-see exhibition for at least four reasons:

1) Every single photo is a masterpiece. Each one of them is breath-takingly beautiful.

2) Each photo is accompanied by short but hugely informative wall captions which are all fascinating in their own right but also build up into an astonishingly encyclopedic overview of all types of human activity around the planet – hugely interesting and mercifully devoid of the moralistic hectoring you are subjected to at so many other exhibitions.

3) It is about the most important subject on earth, which is the way we humans are destroying it.

4) Unlike most art films, ‘In the Wake of Progress’, is a powerful, thrilling, devastating, hopeless, exhilarating watch.

I emerged reeling. I wanted to shake someone’s hand for organising such an overwhelming experience and bow down before Burtynsky’s awesome genius. ‘Extraction/Abstraction’ is quite brilliant.

The Diversity of Life by E.O. Wilson (1992)

It is a failing of our species that we ignore and even despise the creatures whose lives sustain our own. (p.294)

Edward Osborne Wilson was born in 1929 and pursued a long career in biology, specialising in myrmecology, the study of ants, about which he came to be considered the world’s leading expert, and about which he published a massive textbook as well as countless research papers.

As well as his specialist scientific writing, Wilson has also published a series of (sometimes controversial) books about human nature, on collaborative species of animal (which led him to conceive the controversial theory of sociobiology), and about ecology and the environment.

(They’re controversial because he considers humans as just another complex life form, whose behaviour is dictated almost entirely by genetics and environment, discounting our ability to learn or change: beliefs which are opposed by liberals and progressives who believe humans can be transformed by education and culture.)

The Diversity of Life was an attempt to give an encyclopedic overview of life on earth – the myriads of life forms which create the dazzlingly complicated webs of life at all levels and in all parts of our planet – and then to inform the reader about the doleful devastation mankind is wreaking everywhere – and ends with some positive suggestions about how to try & save the environment, and the staggering diversity of life forms, before it’s too late.

The book is almost 30 years old but still so packed with information that maybe giving a synopsis of each chapter would be useful.


Part one – Violent nature, resilient life

1. Storm over the Amazon An impressionistic memoir of Wilson camping in the rainforest amid a tropical storm, which leads to musings about the phenomenal diversity of life forms in such places, and beyond, in all parts of the earth, from the Antarctic Ocean to deep sea, thermal vents.

2. Krakatau A vivid description of the eruption of Krakatoa leads into an account of how the sterile smoking stump of island left after the explosion was swiftly repopulated with all kinds of life forms within weeks of the catastrophe and now, 130 years later, is a completely repopulated tropical rainforest. Life survives and endures.

3. The Great Extinctions If the biggest volcanic explosion in recorded history can’t eliminate life, what can? Wilson explains the five big extinction events which the fossil record tells us about, when vast numbers of species were exterminated:

  • Ordovician 440 million years ago
  • Devonian 365 million years ago
  • Permian 245 million years ago
  • Triassic 210 million years ago
  • Cretaceous 66 million years ago

The last of these being the one which – supposedly – wiped out the dinosaurs, although Wilson points out that current knowledge suggests that dinosaur numbers were actually dropping off for millions of years before the actual ‘event’, whatever that was (most scientists think a massive meteor hit earth, a theory originally proposed by Luis Alvarez in 1980).

Anyway, the key thing is that the fossil record suggests that it took between five and 20 million years after each of these catastrophic events for the diversity of life to return to something like its pre-disaster levels.


Part two – Biodiversity rising

4. The Fundamental Unit A journey into evolutionary theory which quickly shows that many of its core concepts are deeply problematic and debated. Wilson clings to the notion of the species as the fundamental unit, because it makes sense of all biology –

A species is a population whose members are able to interbreed freely under natural conditions (p.36)

but concedes that other biologists give precedence to other concepts or levels of evolution, for example the population, the deme, or focus on genetics.

Which one you pick depends on your focus and priorities. The ‘species’ is a tricky concept to define, with the result that many biologists reach for subspecies (pp.58-61).

And that’s before you examine the record chronologically i.e. consider lineages of animals which we know stretch back for millions of years: at what point did one species slip into another? It depends. It depends what aspects you choose to focus on – DNA, or mating rituals, or wing length or diet or location.

The message is that the concepts of biology are precise and well-defined, but the real world is far more messy and complicated than, maybe, any human concepts can really fully capture.

5. New Species Wilson details all the processes by which new species have come about, introducing the concept of ‘intrinsic isolating mechanisms’, but going on to explain that these are endless. Almost any element in an environment, an organisms’s design or DNA might be an ‘isolating mechanism’, in the right circumstances. In other words, life forms are proliferating, mutating and changing constantly, all around us.

The possibility for error has no limit, and so intrinsic isolating mechanisms are endless in their variety. (p.51)

6. The forces of evolution Introduces us to a range of processes, operating at levels from genetics to entire populations, which drive evolutionary change, including:

  • genetic mutation
  • haploidy and diploidy (with an explanation of the cause of sickle-cell anaemia)
  • dominant and recessive genes
  • genotype (an individual’s collection of genes) and phenotype (the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment)
  • allometry (rates of growth of different parts of an organism)
  • microevolution (at the genetic level) and macroevolution (at the level of environment and population)
  • the theory of punctuated equilibrium proposed by Niles Eldredge and Stephen Jay Gould (that evolution happens in burst followed by long periods of no-change)
  • species selection

7. Adaptive radiation An explanation of the concepts of adaptive radiation and evolutionary convergence, taking in Hawaiian honeycreepers, Darwin’s finches on the Galapagos Islands, the cichlid fish of Lake Victoria, the astonishing diversity of shark species, and the Great American Interchange which followed when the rise of the Panama Isthmus joined previously separated North and South America 2.5 million years ago.

Ecological release = population increase that occurs when a species is freed from limiting factors in its environment.

Ecological constraint = constriction in the presence of a competitor.

8. The unexplored biosphere Describes our astonishing ignorance of how many species there are in the world. Wilson gives the total number of named species as 1.4 million, 751,000 of them insects, but the chapter goes on to explain our complete ignorance of the life forms in the ocean depths, or in the rainforest canopies, and the vast black hole of our ignorance of bacteria.

There could be anything between 10 million and 100 million species on earth – nobody knows.

He explains the hierarchy of toxonomy of living things: kingdom, phylum or division, class, order, family, genus, species.

Equitability = the distribution of diversity in a given location.

9. The creation of ecosystems Keystone species hold a system together e.g. sea otters on the California coast (which ate sea urchins thus preventing the sea urchins eating the kelp, so giving rise to forests of kelp which supported numerous life forms including whales who gave birth close to the forests of kelp) or elephants in the savannah (who, by pushing over trees, create diverse habitats).

Elasticity.

The predator paradox – in many systems it’s been shown that removing the top predator decreases diversity).

Character displacement. Symbiosis. The opposite of extinction is species packing.

The latitudinal diversity gradient i.e. there is more diversity in tropical rainforests – 30% of bird species, probably over half of all species, live in the rainforests – various theories why this should be (heat from the sun = energy + prolonged rain).

10. Biodiversity reaches the peak The reasons why biodiversity has steadily increased since the Cambrian explosion 550 million years ago, including the four main steps in life on earth:

  1. the origin of life from prebiotic organic molecules 3.9 billion years ago
  2. eukaryotic organisms 1.8 billion years ago
  3. the Cambrian explosion 540 to 500 million years ago
  4. the evolution of the human mind from 1 million to 100,000 years ago.

Why there is more diversity, the smaller the creatures/scale – because, at their scale, there are so many more niches to make a living in.


Part three – The human impact

It’s simple. We are destroying the world’s ecosystems, exterminating untold numbers of species before we can even identify them and any practical benefits they may have.

11. The life and death of species ‘Almost all the species that have ever lived are extinct, and yet more are alive today than at any time in the past (p.204)

How long do species survive? From 1 to 10 million years, depending on size and type. Then again, it’s likely that orchids which make up 8% of all known flowering plants, might speciate, thrive and die out far faster in the innumerable microsites which suit them in mountainous tropics.

The area effect = the rise of biodiversity according to island size (ten times the size, double the number of species). Large body size means smaller population and greater risk of extinction. The metapopulation concept of species existence.

12. Biodiversity threatened Extinctions by their very nature are rarely observed. Wilson devotes some pages to the thesis that wherever prehistoric man spread – in North America 8,000 years ago, in Australia 30,000 years ago, in the Pacific islands between 2,000 and 500 years ago – they exterminated all the large animals.

Obviously, since then Western settlers and colonists have been finishing off the job, and he gives depressing figures about numbers of bird, frog, tree and other species which have been exterminated in the past few hundred years by Western man, by colonists.

And now we are in a new era when exponentially growing populations of Third World countries are ravaging their own landscapes. He gives a list of 18 ‘hotspots’ (New Caledonia, Borneo, Ecuador) where half or more of the original rainforests has been heart-breakingly destroyed.

13. Unmined riches The idea that mankind should place a cash value on rainforests and other areas of diversity (coral reefs) in order to pay locals not to destroy them. Wilson gives the standard list of useful medicines and drugs we have discovered in remote and unexpected plants, wondering how many other useful, maybe life-saving substances are being trashed and destroyed before we ever have the chance to discover them.

But why  should this be? He explains that the millions of existing species have evolved through uncountable trillions of chemical interactions at all levels, in uncountably vast types of locations and settings – and so have been in effect a vast biochemical laboratory of life, infinitely huger, more complex, and going on for billions of years longer than our own feeble human laboratory efforts.

He gives practical examples of natural diversity and human narrowness:

  • the crops we grow are a handful – 20 or so – of the tens of thousands known, many of which are more productive, but just culturally alien
  • same with animals – we still farm the ten of so animals which Bronze Age man domesticated 10,000 years ago when there is a world of more productive animals e.g. the giant Amazon river turtle, the green iguana, which both produce far more meat per hectare and cost than beef cattle
  • why do we still fish wild in the seas, devastating entire ecosystems, when we could produce more fish more efficiently in controlled farms?
  • the absolutely vital importance of maintaining wild stocks and varieties of species we grow for food:
    • when in the 1970s the grassy-stunt virus devastated rice crops it was only the lucky chance that a remote Indian rice species contained genes which granted immunity to the virus and so could be cross-bred with commercial varieties which saved the world’s rice
    • it was only because wild varieties of coffee still grew in Ethiopia that genes could be isolated from them and cross-bred into commercial coffee crops in Latin America which saved them from devastation by ‘coffee rust’
  • wipe out the rainforests and other hotspots of diversity, and there go your fallback species

14. Resolution As ‘the human juggernaut’ staggers on, destroying all in its path, what is to be done? Wilson suggests a list:

  1. Survey the world’s flora and fauna – an epic task, particularly as there are maybe only 1,500 scientists in the whole world qualified to do it
  2. Create biological wealth – via ‘chemical prospecting’ i.e. looking for chemicals produced by organisms which might have practical applications (he gives a list of such discoveries)
  3. Promote sustainable development – for example strip logging to replace slash and burn, with numerous examples
  4. Wilson critiques the arguments for
    • cryogenically freezing species
    • seed banks
    • zoos
  5. They can only save a tiny fraction of species, and then only a handful of samples – but the key factor is that all organisms can only exist in fantastically complicated ecosystems, which no freezing or zoosor seed banks can preserve. There is no alternative to complete preservation of existing wilderness

15. The environmental ethic A final summing up. We are living through the sixth great extinction. Between a tenth and a quarter of all the world’s species will be wiped out in the next 50 years.

Having dispensed with the ad hoc and limited attempts at salvage outlined above, Wilson concludes that the only viable way to maintain even a fraction of the world’s biodiversity is to identify the world’s biodiversity ‘hot spots’ and preserve the entire ecosystems.

Each ecosystem has intrinsic value (p.148)

In the last few pages he makes the ‘deepest’ plea for conservation based on what he calls biophilia – this is that there is all kinds of evidence that humans need nature: we were produced over 2 million years of evolution and are descended from animals which themselves have encoded in the genes for their brains and nervous systems all kinds of interactions with the environment, with sun and moon, and rain and heat, and water and food, with rustling grasses and sheltering trees.

The most basic reason for making heroic efforts to preserve biodiversity is that at a really fundamental level, we need it to carry on feeling human.

On planet, one experiment (p.170)


Conclusion

Obviously, I know human beings are destroying the planet and exterminating other species at an unprecedented rate. Everyone who can read a newspaper or watch TV should know that by now, so the message of his book was over-familiar and sad.

But it was lovely to read again several passages whose imaginative brio had haunted me ever since I first read this book back in 1994:

  • the opening rich and impressionistic description of the rainforest
  • a gripping couple of pages at the start of chapter five where he describes what it would be like to set off at walking pace from the centre of the earth outwards, across the burning core, then into the cooler mantle and so on, suddenly emerging through topsoil into the air and walking through the extraordinary concentration of billions of life forms in a few minutes – we are that thin a layer on the surface of this spinning, hurtling planet
  • the couple of pages about sharks, whose weird diversity still astonishes
  • the brisk, no-nonsense account of how ‘native’ peoples or First Peoples were no tender-hearted environmentalists but hunted to death all the large megafauna wherever they spread
  • the dazzling description of all the organisms which are found in just one pinch of topsoil

As to the message, that we must try and preserve the diversity of life and respect the delicate ecosystems on which our existence ultimately depends – well, that seems to have been soundly ignored more or less everywhere, over the past thirty years since the book was published.
