On social norms.

On social norms.

I assume that you, personally, have never clear-cut and burned a patch of the Amazon rain forest.  Neither have I.  The number of people who have done the actual cutting is vanishingly small compared to the world’s population.

I also assume that you enjoy living in a world where the Amazon rain forest exists — certainly more than you’d enjoy living in a world where it had all been slashed and burned.  If we lose the Amazon rain forest, climate change might spiral out of control, flooding coastal cities worldwide and causing desertification in much of the interior United States.  If we lose the Amazon rain forest, huge numbers of species will go extinct, including a wide variety of medicinal plants that we’ve only begun to investigate.

And the rain forest is beautiful.  Future generations would feel an ache of want – likely compounded with a mix of jealousy and anger – if they saw photographs of the Amazon rain forest after it were gone.

When I was in elementary school, my third grade class sponsored a patch of the Amazon rain forest.  In retrospect, I’m not sure what this entailed.  We raised money and sent it off in an envelope.  I don’t remember whether we ever saw photographs of “our” forest, whether the arrangement was supposedly akin to a rental or purchase of those trees. 

I have no idea who received our sponsorship money, but the general idea that money should be sent from the U.S. to Brazil is actually correct.  Many of the world’s problems would be easier to address if we used a global wealth tax to fund a guaranteed basic income for everyone.  At the very least, if there are natural resources that benefit all of humanity, then countries that are currently wealthy because they ravaged their environments should pay to encourage other nations not to accrue wealth through extractive industries.

Some people in Brazil would be wealthier if the Amazon rain forest were destroyed.  Everyone in the world would suffer as a result.  If we – everyone outside Brazil – would prefer that the rain forest not be destroyed, we should compensate Brazilians for the foregone short-term economic benefits.

Unless you are fantastically wealthy, you personally will be unable to enact this policy on your own.  If I decided to split my family’s entire annual income among the people of Brazil, each would get 2% of a penny … and my family would be left with nothing.

A guaranteed basic income is the right policy, but it’s not something that I can accomplish as an individual.

In We Are the Weather, Jonathan Safran Foer discusses how each one of us can help preserve the Amazon rain forest today.  We as a people should strive for political solutions to the world’s problems, but we as individuals shouldn’t make choices that exacerbate those very problems.  It would seem hypocritical to lobby for fines against littering if we continued to blithely toss candy bar wrappers onto the ground.

Foer describes how painful it feels to recognize this hypocrisy in himself.  This sensation grows more intense as he watches his children grow in a world that is becoming increasingly dangerous.

But what kind of father prioritizes feeling good over doing good?

Foer knows that he could choose to help.  Each day, he could act in a way that makes his children’s world safer.

He often doesn’t.

There is a far more pernicious form of science denial than Trump’s: the form that parades as acceptance.  Those of us who know what is happening but do far too little about it are more deserving of the anger.  We should be terrified of ourselves.  We are the ones we have to defy.  I am the person endangering my children.

As you read this, the Amazon rain forest is being destroyed.  Why?  To clear space for cows to graze.

Photo by Joelle Hernandez on Flickr, whose caption from this 2007 photograph reads, “On a few occasions Brazilians told me that ‘People thousands of miles away are contributing to our deforestation.'”

Even if the meat or cheese you eat was not imported from Brazil, by choosing to eat it, you are reinforcing the social norm that is causing the Amazon rain forest to be destroyed. 

Eating meat is pleasurable.  A good cheese pizza can be divine.  Humans evolved as omnivores, and the tastes of meat and cheese are particularly delicious.  Choosing not to eat these foods would be a sacrifice.

Foer has tried to be a vegetarian for decades.  He has previously written about the animal welfare arguments against eating meat; now he’s written about the environmental arguments.  He knows that eating meat is immoral – the cow suffered to produce it, and Foer’s own children will suffer a worse climate as a consequence.

But this knowledge isn’t enough.  He still surreptitiously buys cheeseburgers.

So why hasn’t vegetarianism become any easier after thirty years?  Why has it become harder?  I crave meat more now than I have at any point since I became a vegetarian.

Foer wishes that there were a social norm to eat only foods made from plants. 

Eating meat is pleasurable.  Eating cheese is pleasurable. 

Injecting heroin is pleasurable too.  Driving a car while drunk is pleasurable.  Heck, even cruising down the road while everybody else pulls aside for the ambulance behind you would be pleasurable.

In our culture, there’s a social norm to pull aside for ambulances.  Even though it would be more pleasurable to keep driving, most people don’t.

Meats and cheeses are responsible for somewhere between 20% and 50% of all climate-change-causing emissions. 

(There’s a wide range in that estimate because, although it’s incontestable that it takes more land to produce meats and cheeses than it does to make equivalent foods from plants, it’s debatable what would be done with all that extra land if people changed their diets.  If the extra space would be used to restore forests, then animal agriculture is responsible for 50% of climate change.  If the extra space would be kept as grass – setting aside the curious question of why – then animal agriculture causes only 20% of climate change.  Only 20%.  By way of comparison, all the world’s cars, trucks, and airplanes together cause less than 15% of climate change.  You can look at the appendix to We Are the Weather for an explanation of these numbers, or even glance at Donald Trump’s EPA website for some pie charts with identical information.)

The current administration has gutted the EPA, and compelled their staff scientists to restate their findings in the weakest ways possible … and these are the numbers still posted on their website.

If every gasoline-powered car was replaced with a hybrid vehicle – instantly, world-wide – greenhouse gas emissions would be about 96% of what they are currently.  If that was the only change we made, our planet would be toast.

If we all followed a social norm to eat food made from plants, greenhouse gas emissions could be 50% of what they are currently.  With no other changes, humanity would survive.  Our planet would remain habitable for our children, and our grandchildren.

Pleasure matters.  I’m an atheist, and I’m well aware that the eventual heat death of the universe means humanity will go extinct eventually.  I don’t believe you can make a viable philosophical argument for existence based on helpfulness or social connections alone – your life needs to be pleasurable, too.

Your life can be pleasurable without meat or cheese.  I support responsible hedonism.  Good food is a joy, but you can eat well while making only choices that protect our planet.  Most people think that sex is great fun, but we have a social norm that you should enjoy your sexuality only with other consenting adults.  Groping a beautiful stranger might be more fun than eating cheese – in our culture, a social norm restrains us. 

Well, most of us.

Foer wishes that we, as a people, could choose better.  He’s been struggling to eat food made from plants.  But he doesn’t struggle to restrain himself from murder, or theft, or groping his students.  In those instances, our social norms make it easy to do the right thing.

And you can still be a hedonist while eating plants!  If you’re ever in Chicago, you should stop by my dear friend Auntie Ferret’s vegan deep-dish pizza restaurant, or use Happy Cow to find a decadent plant-based restaurant near you.

On national borders and the disappearance of our universe’s only known habitable planet.

On national borders and the disappearance of our universe’s only known habitable planet.

When our eldest child was two years old, a friend of ours built a caterpillar home from some window screens we found in the dumpster.  Our neighbor gave us milkweed, and we raised some monarchs.

In recent decades, increased use of pesticides and the decreased abundance of milkweed along monarch migratory routes have caused butterfly populations to plummet.  And so many suburban homeowners began to cultivate milkweek in their yards.  Exceptionally dedicated butterfly conservationists began to raise caterpillars inside, keeping them safe from predation, and checking to make sure that the butterflies were free of parasitic protozoans before release.

The hope is that, with enough concerned citizens pitching in to help, monarch populations might rebound.  Within the span of a single lifetime, insect populations around the world have fallen precipitously, in many regions by 90% or more, a travesty described eloquently in Michael McCarthy’s The Moth Snowstorm:

It had been the most powerful of all the manifestations of abundance, this blizzard of insects in the headlights of cars, this curious side effect of technology, this revelatory view of the natural world which was only made possible with the invention of the motor vehicle.  It was extraordinary; yet even more extraordinary was the fact that it had ceased to exist.  Its disappearance spoke unchallengeably of a completely unregarded but catastrophic crash in Britain of the invertebrate life which is at the basis of so much else. 

South Korea may have destroyed Saemangeum, and China may have destroyed its dolphin, but my own country has wrecked a destruction which is just as egregious; in my lifetime, in a process that began in the year I was born, in this great and merciless thinning, it has obliterated half its living things, even though the national consciousness does not register it yet. 

That has been my fate as a baby boomer: not just to belong to the most privileged generation which ever walked the earth, but, as we can at last see now, to have my life parallel the destruction of the wondrous abundance of nature that still persisted in my childhood, the abundance which sang like nothing else of the force and energy of life and could be witnessed in so many ways, but most strikingly of all in the astonishing summer night display in the headlight beams, which is no more.

Our kid loved watching the butterflies hatch.  Metamorphosis is an incredible process, especially for a little human undergoing her own transition out of a helpless pupal stage.  Ensuring that our yard is a safe stopover for the monarchs’ journey helps the species survive.

But the monarchs overwinter at a select few sites, such as the mountains of Michoacan.  This state has been ravaged by the drug war.  A huge percentage of the population is mired in poverty, which abets illegal foresting, including cutting down many of the evergreens that the visiting monarchs roost on.  Worse, a large mining company hopes to begin extraction in the butterflies’ overwintering site.  If this project is approved, the monarchs will die, no matter how much milkweed Midwestern homeowners plant in their backyards. 

The people of Michoacan should not be expected to cheerfully endure poverty so that others can look at butterflies.  A major argument in favor of a global wealth tax used to fund a guaranteed basic income is that it would alleviate some of the incentive to destroy our shared environment for private gains.

We all inhabit a single planet – as far as we’ve determined, the only habitable world in the known universe.  And, although our world is very large, we’ve learned recently that individual decisions can have a hugely destructive impact on us all.

In The Uninhabitable Earth, David Wallace-Wells spends two hundred pages describing what life might be like for our children if we allow our planet to warm by two degrees. 

The emergent portrait of suffering is, I hope, horrifying.  It is also, entirely, elective.  If we allow global warming to proceed, and to punish us with all the ferocity we have fed it, it will be because we have chosen that punishment – collectively walking down a path of suicide.  If we avert it, it will be because we have chosen to walk a different path, and endure.

After all, we know what’s happening.  We know why it’s happening.  And we know what we, as individuals, can do to help.  Even comic books published by DC Comics in the 1980s were offering kids advice on what to do:

The solution to our problems is obvious – but I am writing as a wealthy, well-loved, well-educated individual.  I own a home where milkweed can be planted.  My days are happy enough that I don’t feel the need to buy as much stuff as other people.

The world has treated me pretty well.

But why should somebody who has been treated like garbage feel compelled to pitch in? 

In Brazil, under-served people voted Jair Bolsonaro into the presidency.  Bolsonaro hopes to extract value from the country now, which means destroying the Amazon rain forest.  Which means – because this expanse of forest acts akin to a set of lungs for our whole planet – destroying the world.

An interesting comeuppance – as a citizen of the United States, usually it’s the autocratic decrees of my own president that send the world teetering toward destruction.  Indeed, even though 45 has less influence over our planet’s climate than Bolsonaro, he too has been promoting environmental devastation for the sake of extractive industries.

The economics of extraction are interesting.  Because the things we pull from the Earth are all limited resources, their value will presumably rise over time.  People who have money now, like citizens of the U.S., should choose to wait.  Even if we wanted to burn every last bit of the world’s oil and release all that carbon into the atmosphere, we in the U.S. would be better off waiting to pull up our own oil, buying it cheaply from other people now, and then selling ours at a massive profit later on once it’s more scarce.

Instead, oil companies have been operating under an addiction model.  They continue to increase production even when prices are low, as though fearful that an unsteady supply would lead people to kick the habit.  Their future revenue stream would dry up.

Renewable energy has been getting cheaper, so maybe they’re right.  In the meantime, global consumption has been rising every year, even though we know it’s killing us.  Both because our own homes will become less habitable, and because the world will descend into chaotic violence.  From Molly Crabapple’s “Where Else Can They Go,”

the world has come no closer to ensuring the rights of a human without a country.  Mostly, governments propose quarantine.  Internment camps grow in Tornillo, Texas, in Lesbos, in Zaatari, and in Cox’s Bazar in Bangladesh.  It won’t work.  Each year, the world grows warmer.  The oceans rise.  Wars are fought for ever-scarcer resources.  If the wealthy West worries about one million Syrians, what will it do with millions of climate refugees?

Wealthy nations pillaged the world in the past.  Huge amounts of capital were accrued in the meantime, because human productivity was supercharged by the stored fuel of hundreds of thousands of years of extra energy, all that sunlight captured by ancient plants and compressed into oil.

And now, if other nations repeat that process, the world will be destroyed.

The solutions aren’t so hard to come by.  A global wealth tax.  Guaranteed basic income.  These would ameliorate a lot of the world’s problems.  But they require the people who are in power now to willingly accept less.  And the little voice whispering in our ears has quite a bit of practice chanting more.

More.  More.  MORE.

On perspective.

On perspective.

In fantasy novels, trees walk upon their roots and battle with their limbs.  That makes sense to me.  If I think about two trees interacting, I consider the branches; the taller tree shades the other, limiting its competitor’s growth.

But my perspective is upside down.  Trees are standing on the sky, reaching for one another through the earth.  They listen underground.  They communicate down there, passing messages to one another, or even meals.

Picture from “The Wood Wide Web” on New Zealand Geographic.

Perhaps their branches grope for sunlight in the unconscious way that my kids’s feet seek warmth like homing missiles while they sleep.  I try to roll over only to find somebody’s toes wedged under my back.

Year by year, trees inch their feet toward the sun.  And their engaging social lives are hidden from me, buried underground.  My reflexive perspective gives me an inverted image of a tree’s world.

I’m surely not alone in this misunderstanding. 

We humans hold our heads high as we walk across the ground.  A major source of tension in human evolution was arranging our skeletons in such a way that we could walk upright without too many women dying in childbirth – our posture constrains the shape of the pelvis.

Although some species do exhibit dramatically different body morphs between males and females, it’s more common for evolutionary changes in one sex to diffusely alter the other.  Club-winged manakins have bones that are more dense than other birds, which makes them worse at flyingAll club-winged manakins fly poorly, male and female, even though only the males use their dense bones to produce mate-luring music.  Or consider the orgasms and nipples of Homo sapiens, which fulfill important biological purposes in one sex, and serve as a vestigial source of fun for the other.

In prehistoric times, men and women probably hunted together.  The evidence is especially compelling for human populations like the Neanderthal in southern Europe, who lived in such small groups that they would be unable to kill large prey without help from everyone in the group.  But even if prehistoric men had hunted alone, their upright stance and endurance running would have introduced an evolutionary pressure constricting the width of a human pelvis.

Our ancestors first descended from the trees to scavenge meat from lions’ kills.  Eventually, they began to hunt.  Their strategy was to exhaust and bewilder their prey, hoping to use the local geography to assist in each kill.  Mammoths were more likely to fall to their deaths than be slain by hurled spears; mounds of butchered bones accumulated at the base of particularly useful cliffs.

The high caloric density of cooked meat allowed our brains to expand … but the embrace of hunting also caused more women to die in childbirth.

And, less tragically, our upright posture distorts our understanding of the trees that once harbored our communities.  After all, we live in our heads.  It seemed sensible to us that the most interesting life of a tree would transpire in its loftiest branches.

Our biology doesn’t force us to view the world a certain way, but it dictates which perspectives are easiest to take.

Because our brains are story-generating organs, human cultures invariably see time as flowing uniformly in a single direction.  But for subatomic particles, time appears to be symmetrical; the Feynman diagram of an interaction would appear perfectly plausible progressing either forward or backward.

Only our universe’s progression toward greater entropy, i.e. randomness, seems to introduce a directionality for time’s arrow.  But there’s no a priori reason to expect a world to progress toward higher entropy.  This directionality seems to exist only because our particular universe happened to be in an unstable, low entropy state shortly after the Big Bang.

Image from ESA/Hubble.

Or so say most physicists.  From my perspective, I’m content assuming that the past is fixed but the future is mutable.  If I didn’t believe in that asymmetry – whether it’s real or not – I’d probably lapse into despair.

But, again, even if we accept that time is flowing, our perspective alters how we feel about that change.

Is the flow of time progress or decline?

Are a tree’s branches its hands or its feet?

In Indian mythology, time is cyclical, but within each cycle it flows toward corruption.  Time passes and the world grows worse.  Currently we are trapped within a Kali Age, the worst possible world, knowing that all the great heroes have passed.  We are just biding our time before the world can be destroyed and made good again.

After the sunder, time will once again cause that new world’s gleam to fade.  Nothing can stave off the encroach of rot.

In Judaism, the ancient sages lived longer than we do, and knew more, too.  At one point in time, a pair of humans were good: before long, we disobeyed the whims of God and were exiled from paradise.

In The Book of Shem, David Kishik writes that

To be original means to linger by the origin and insist on it.  The task is to avoid the progression toward a future or an end, and to stop the narrative before it develops any further.  In this sense, and in this sense only, the origin is a worthwhile goal.  Hence in Hebrew forward (kadima) is related to what is ancient (kadum), just as backward (achora) is linked to what is last (acharon).

Many humans want to reclaim the imagined glories of the past.

To make America great again, perhaps.

I personally think that many recent technological developments in our world are bad.  We’ve designed distracting, addicting telephones, and we’re putting them into the hands of children.  Our brains evolved to be extremely plastic, which let our species adapt to a wide variety of circumstances … but this neural plasticity allows exposure to fabulous, drug-like devices to dramatically alter our brains, probably for the worse.

And we’ve designed distracting, addicting advertising platforms – these siphon huge amounts of money away from productive industries, and the perverse economic incentives we’ve constructed allow these companies, alongside equally-unhelpful investment banks, to lure many of the most clever college graduates to their ranks.

But I’m certainly no Luddite, pining for a purer past.  The world was a terrible place for so many people.  Although I appreciate the thesis that Yuval Noah Harari presents in Sapiens – that the invention of agriculture made people’s lives worse than when all humans were hunters and gatherers – I see those grim millennia as akin to the hump in a chemical reaction, a transition that must be traversed in order to reach the desired products.

For generations, most people scraped out a miserable existence by subsistence farming.  Their lives were worse than their ancestors’.  But we, now, can feed so many people so easily that we could make our world into a paradise.

We’re not doing it, but we could.

At least we’re making baby steps toward a society in which people aren’t punished for their genetic background, or gender, or religious beliefs.  I mean, even in the United States we still treat women shabbily; across the country, racist police departments beleaguer Black citizens; atheists and Muslims are eyed with distrust.

But it used to be worse.

And, sure, even if we were the best of stewards, our planet would eventually be doomed.  Even if we don’t exhaust the resources here on Earth, the sun will run out of energy and bloat to engulf our world in a ball of fire.  Maybe that’s fine.  Death is a part of my life; perhaps I should look upon extinction as a natural part of humanity’s journey through time.

But it’s so cool to image people someday spreading amongst the stars.  I dream about the future.  And hope against hope – despite overpopulation, climate change, and all – that my children will find a better world than the one I’ve been living in.

Image by D Mitriy.

From my perspective, time will let us make the world better. 

Although it surely won’t happen on its own.  We will have to work to make it better.  The work might not be that hard.  Just live the way you would if the world were already the place it ought to be.

On suboptimal optimization.

On suboptimal optimization.

I’ve been helping a friend learn the math behind optimization so that she can pass a graduation-requirement course in linear algebra. 

Optimization is a wonderful mathematical tool.  Biochemists love it – progression toward an energy minimum directs protein folding, among other physical phenomena.  Economists love it – whenever you’re trying to make money, you’re solving for a constrained maximum.  Philosophers love it – how can we provide the most happiness for a population?  Computer scientists love it – self-taught translation algorithms use this same methodology (I still believe that you could mostly replace Ludwig Wittgenstein’s Philosophical Investigations with this New York Times Magazine article on machine learning and a primer on principal component analysis).

But, even though optimization problems are useful, the math behind them can be tricky.  I’m skeptical that this mathematical technique is essential for everyone who wants a B.A. to grasp – my friend, for example, is a wonderful preschool teacher who hopes to finally finish a degree in child psychology.  She would have graduated two years ago except that she’s failed this math class three times.

I could understand if the university wanted her to take statistics, as that would help her understand psychology research papers … and the science underlying contemporary political debates … and value-added models for education … and more.  A basic understanding of statistics might make people better citizens.

Whereas … linear algebra?  This is a beautiful but counterintuitive field of mathematics.  If you’re interested in certain subjects – if you want to become a physicist, for example – you really should learn this math.  A deep understanding of linear algebra can enliven your study of quantum mechanics.

The summary of quantum mechanics: animation by Templaton.

Then again, Werner Heisenberg, who was a brilliant physicist, had a limited grasp on linear algebra.  He made huge contributions to our understanding of quantum mechanics, but his lack of mathematical expertise occasionally held him back.  He never quite understood the implications of the Heisenberg Uncertainty Principle, and he failed to provide Adolph Hitler with an atomic bomb.

In retrospect, maybe it’s good that Heisenberg didn’t know more linear algebra.

While I doubt that Heisenberg would have made a great preschool teacher, I don’t think that deficits in linear algebra were deterring him from that profession.  After each evening that I spend working with my friend, I do feel that she understands matrices a little better … but her ability to nurture children isn’t improving.

And yet.  Somebody in an office decided that all university students here need to pass this class.  I don’t think this rule optimizes the educational outcomes for their students, but perhaps they are maximizing something else, like the registration fees that can be extracted.

Optimization is a wonderful mathematical tool, but it’s easy to misuse.  Numbers will always do what they’re supposed to, but each such problem begins with a choice.  What exactly do you hope to optimize?

Choose the wrong thing and you’ll make the world worse.


Figure 1 from Eykholt et al., 2018.

Most automobile companies are researching self-driving cars.  They’re the way of the future!  In a previous essay, I included links to studies showing that unremarkable-looking graffiti could confound self-driving cars … but the issue I want to discuss today is both more mundane and more perfidious.

After all, using graffiti to make a self-driving car interpret a stop sign as “Speed Limit 45” is a design flaw.  A car that accelerates instead of braking in that situation is not operating as intended.

But passenger-less self-driving cars that roam the city all day, intentionally creating as many traffic jams as possible?  That’s a feature.  That’s what self-driving cars are designed to do.

A machine designed to create traffic jams?

Despite my wariness about automation and algorithms run amok, I hadn’t considered this problem until I read Adam Millard-Ball’s recent research paper, “The Autonomous Vehicle Parking Problem.” Millard-Ball begins with a simple assumption: what if a self-driving car is designed to maximize utility for its owner?

This assumption seems reasonable.  After all, the AI piloting a self-driving car must include an explicit response to the trolley problem.  Should the car intentionally crash and kill its passenger in order to save the lives of a group of pedestrians?  This ethical quandary is notoriously tricky to answer … but a computer scientist designing a self-driving car will probably answer, “no.” 

Otherwise, the manufacturers won’t sell cars.  Would you ride in a vehicle that was programmed to sacrifice you?

Luckily, the AI will not have to make that sort of life and death decision often.  But here’s a question that will arise daily: if you commute in a self-driving car, what should the car do while you’re working?

If the car was designed to maximize public utility, perhaps it would spend those hours serving as a low-cost taxi.  If demand for transportation happened to be lower than the quantity of available, unoccupied self-driving cars, it might use its elaborate array of sensors to squeeze into as small a space as possible inside a parking garage.

But what if the car is designed to benefit its owner?

Perhaps the owner would still want for the car to work as a taxi, just as an extra source of income.  But some people – especially the people wealthy enough to afford to purchase the first wave of self-driving cars – don’t like the idea of strangers mucking around in their vehicles.  Some self-driving cars would spend those hours unoccupied.

But they won’t park.  In most cities, parking costs between $2 and $10 per hour, depending on whether it’s street or garage parking, whether you purchase a long-term contract, etc. 

The cost to just keep driving is generally going to be lower than $2 per hour.  Worse, this cost is a function of the car’s speed.  If the car is idling at a dead stop, it will use approximately 0.1 gallon per hour, costing 25 cents per hour at today’s prices.  If the car is traveling at 30 mph without breaks, it will use approximately 1 gallon per hour, costing $2.50 per hour.

To save money, the car wants to stay on the road … but it wants for traffic to be as close to a standstill as possible.

Luckily for the car, this is an easy optimization problem.  It can consult its onboard GPS to find nearby areas where traffic is slow, then drive over there.  As more and more self-driving cars converge on the same jammed streets, they’ll slow traffic more and more, allowing them to consume the workday with as little motion as possible.

Pity the person sitting behind the wheel of an occupied car on those streets.  All the self-driving cars will be having a great time stuck in that traffic jam: we’re saving money!, they get to think.  Meanwhile the human is stuck swearing at empty shells, cursing a bevy of computer programmers who made their choices months or years ago.

And all those idling engines exhale carbon dioxide.  But it doesn’t cost money to pollute, because one political party’s worth of politicians willfully ignore the fact that capitalism, by philosophical design, requires we set prices for scarce resources … like clean air, or habitable planets.

On two degrees and the worst year (yet) to be alive.

On two degrees and the worst year (yet) to be alive.

The United States is pumping more carbon dioxide into the atmosphere than we were last year.

The amount of heat-trapping gas in our atmosphere is already too high – ideally, our net emissions should be negative.  Which is entirely feasible.  When we cultivate forests, trees pull carbon from the air.  But each tree can do only so much.  We also need to reduce the amount of energy we consume.

We don’t need to be less happy, though.  As the economy improved, people began flying more … but many flights aren’t producing happiness.  Most people look harried and sullen in airports.  If we all switched to taking trains, the cultural expectations for the rhythm of our lives would shift – instead of short bursts of misery, our travels could be pleasant spells of intermediate time. 

And the giant server farms needed to run websites like Facebook gobble energy.  Facebook, just like any other advertising company, profits by making people less happy.  Many people would be happier in a world where these servers used less energy.

We have a compelling reason to change our behaviors.  If we don’t, the global climate will rise by two degrees Celsius or more.  (Of course, any individual location could become much warmer or colder – a nearby warm ocean current keeps Europe’s climate mild, but if melting polar ice redirects this current, countries like England could become quite frigid.)

How different might life be if global temperatures changed by two degrees?

In the year 536, global temperatures were about two degrees lower than they are today.  (Which does prove, obviously, that the global climate can change for reasons that are not humanity’s fault.  But the current changes are caused by us.)

Historian and archaeologist Michael McCormick believes that this two degree change in temperature made our planet an utterly miserable place to live. A volcanic eruption had darkened the sky, preventing incoming sunlight from warming Earth.  “It was the beginning of one of the worst periods to be alive, if not the worst year,” says McCormick. Snow fell in summertime; crops failed; people starved.

And now we, in all our wisdom, are about to tug the needle just as far (if not farther!) in the other direction.

The Dark Ages were literally dark.  Ashen clouds lurked overhead.  Beset by such nightmarish conditions, people feared that God had forsaken them.  Europeans abandoned science and literacy partly as penance, hoping to appease the source of wrath that was killing them and their children.

Plants have evolved on Earth for many millions of years.  Many plant species will find a way to endure even if we change our planet’s climate.  But human food crops are quite young, in evolutionary terms, and exist in precarious swaths of monoculture. A two degree increase in global temperatures will cause these plants to die.  Famine will ensue.  Global violence and warfare will increase as hungry people fight to survive. 

A two degree change in temperature is totally sufficient to usher in a new worst year to be alive.

Sadly, nobody will be eating any Doritos made from these drought-scorched corn plants.

If we change the global climate by two degrees, there’s also no assurance that our planet won’t keep warming.  Weather is dictated by complex feedback loops that we don’t yet understand.  Our oceans soak up heat, which is changing their chemistry; warmer water takes up more space, flooding the coasts, and will melt the polar ice caps from underneath, which further accelerates warming because ice reflects sunlight, but bare ground or water absorbs it.

Venus may have been habitable, once. But climate change spiraled out of control after the atmosphere filled with too much heat-trapping carbon dioxide.  The oceans evaporated.  Now, searing sulfuric acid falls as rain from the sky.

If we tip over the precipice, every living creature on earth will be doomed.  No one understands enough about the feedback loops that dictate a planet’s climate to know how close to the precipice we are.

Although, really, a two degree change would be awful enough.

Which is worth reiterating … especially because the cohort of humans that has contributed most to climate change, and currently holds the wealth and political power needed to prevent catastrophe, is of an age that perhaps they want the world to be a little warmer.  Wealthy Americans in their fifties to seventies have long migrated south in pursuit of warmer climate.

The current generation of 50- to 70-year-olds was given the most of the Earth’s plenitude.  The world of their youth was very different from the world in which my children were born. While that generation was alive, insect populations plummeted by 90% or more.  The fecundity of other wildlife diminished in turn.  Forests were clearcut, and the environment – including the very air we breathe – was devastated to produce the world’s current wealth.

Perhaps some of the people in power now do want a warmer planet.  But it is not theirs.  As phrased by Wendell Berry,

the world is not given by [our parents], but borrowed from [our] children.”

We should feel horrifically embarrassed to return this world in worse condition than when we were lent it.

On extraction.

On extraction.

The womb-suckers are trying to eat your children. Poke a soda straw into the future and sluuurp, away they go.  Hopes and dreams, metabolized today into so many dollar bills.

I spend a fair bit of time with drug dealers. Most are ethical people – they wanted to ingest drugs, and they knew some other people who wanted to ingest drugs, so they started selling.

But there’s an unethical way to push – some dealers focus on getting new users hooked.  That way they’ll have a steady income stream.  Most of the guys in my poetry class, if somebody talks about getting clean, congratulate and encourage the dude.  But some dealers would see rehab as a threat to their own livelihoods.

The future-eaters are like the second type of dealer.  They’re trying to kill babies – including babies who haven’t even been conceived yet – while proffering incredibly cynical rationalizations.

Yup, you’re right, kid.  Earth is beautiful. 
I’m sorry the grown-ups aren’t trying very hard to keep Earth beautiful.

Here’s the deal: regions of the Earth’s crust that lie beneath territories claimed by the United States contain rich deposits of hydrocarbons.  These could be dug up and combusted to power our factories, our automobiles, our giant arrays of computer servers that enable the internet.  The average person’s lifestyle in the U.S.gobbles energy, and deep below our lands is solar energy that photosynthesizing plants captured millions of years ago.

But we now know that there is only a limited amount of ancient stored sunlight beneath us.  The world’s oil reserves will eventually be depleted.  And so a smart investor, even if that investor believed that all the hydrocarbons beneath us should be combusted, bringing our planet closer to the hellhole that runaway climate change allowed Venus to become, would decide to wait.  Right now, the price of oil is low.  The total supply of oil is decreasing.  The population is rising.  If oil really is the best energy source, then the price will obviously rise. 

Venus was habitable once, but after atmospheric carbon dioxide levels got too high, climate change spiraled out of control.  I certainly wouldn’t want to live there now. Artist rendition from NASA.

I believe this relationship, lower supply = higher price, is taught within the first two lectures of any undergraduate economics course.

Since we’re rich enough to do it, we would make more money by buying oil now from those foolish countries who need cash right away and are currently selling their buried wealth, then extracting our own oil later when the total supply is lower and each barrel is worth more money.

The womb-suckers love money.  So why isn’t this their plan?

After all, we as a nation are wealthy enough to invest.  Throughout the ages, that’s what people blessed with current prosperity have done. By socking away money now – maybe by lending it to a neighbor and charging interest – you gain a constant source of income for the future.

The usual stereotype is that it’s foolish poor people who eat the future.  When you’re starving, you might eat seeds from the granary.  That’ll help you survive another winter, but next year the famine will hit even worse.  Methamphetamines let you trade away future health to do more today.  So do cigarettes.

The womb-suckers rarely pull drags of nicotine into their own bodies.  But they’ll happily light one for our planet.

The president of the U.S. wants to drill for oil beneath the Arctic National Wildlife Refuge.  The president of Brazil wants to cut down the Amazon rain forest for gold mines and hamburgers.

But there is a framework in which their urgency to eat the future is rational.  If people will notice what’s happening and stop them later, they need to get it done now. The window for personal gain is closing: slash and burn while you can.

And there is, of course, the comparison to an unethical drug dealer.  You have to keep selling even when the heat is closing in because otherwise your customers could get clean and then you can’t make money off your product anymore.

We’ve reached a point where many people have realized that the future is in peril –most people who get their news from any source other than the state-endorsed propaganda network – but, let’s face it, people are lazy.  I’m lazy too.  Even though I know that disposable diapers are wasteful to manufacture and then ship off to landfills, my family resorts to them during weeks when we’re too overwhelmed to wash another load of excrement-encrusted rags.

Similarly, everyone knows that a vegan diet is better for the planet. But most people still eat meat. The Republican party’s big-government subsidies make hamburgers cheap … and those burgers are already cooked, waiting at the drive through, chock full of delicious fat, salt, and MSG. Being vegan takes more effort.

But we’re well-meaning, most of us.  And lazy, well-meaning people just need a little nudge to start doing the right thing.

The womb-suckers are justifiably worried that a small hiccup in the rate of extraction now might be the final nudge necessary to get the world to change.  Switch to renewable energy.  Recycle and re-use more of what we’ve already dug from the ground.

The womb-suckers need to flood the market, get what money they can before the rest of us sober up.  It’s the best thing for a murderous hedonist to do; with enough money, they can soar the skies in gold-plated airplanes.  With enough money, even boorish, ugly men have a shot at having sex with pornographic film stars.

The future eaters see no contradiction, calling themselves “pro-life” while they frantically strive to make billions of unborn children die.

On the water-fueled car.

On the water-fueled car.

“I heard there was, like, a car that runs on water … “

“Dude, no, there’ve been, like, six of them.  But oil companies bought all the patents.”

A lot of the people who attend my poetry class in jail believe in freaky conspiracy theories.  Somebody started telling me that the plots of various Berenstain Bears books are different from when he was a child, which is evidence that the universe bifurcated and that he’s now trapped in an alternate timeline from the path he was on before …

old hat(New printings of some Berenstain Bears books really are different.  Take Old Hat New Hat, a charming story about shopping and satisfaction: after the protagonist realizes that he prefers the old, beat-up hat he already owns to any of the newer, fancier models, a harried salesperson reacts with a mix of disgust and disbelieve.  This scene has been excised from the board book version that you could buy today.  Can’t have anything that tarnishes the joy of consumerism!)

I’ve written about conspiracy theories previously, but I think it’s worth re-iterating, in the interest of fairness, that the men in jail are correct when they assume that vast numbers of people are “breathing together” against them.  Politicians, judges, police, corporate CEOs and more have cooperated to build a world in which men like my students are locked away.  Not too long ago, it would have been fairly easy for them to carve out a meaningful existence, but advances in automation, the ease of international shipping, and changes to tax policy have dismantled the opportunities of the past.

Which means that I often find myself seriously debating misinterpretations of Hugh Everett’s “many worlds” theory (described midway through my essay, “Ashes”), or Biblical prophecies, or Jung-like burblings of the collective unconsciousness.

Or, last week, the existence of water cars.

In 2012, government officials from Pakistan announced that a local scientist had invented a process for using water as fuel.  At the time, I was still running a webcomic – one week’s Evil Dave vs. Regular Dave focused on news of the invention.


When scientists argue that a water-powered car can’t exist, they typically reference the Second Law of Thermodynamics (also discussed in “Ashes”).  The Second Law asserts that extremely unlikely events occur so rarely that you can safely assume their probability to be zero.

If something is disallowed by the Second Law, there’s nothing actually preventing it from happening.  For an oversimplified example, imagine there are 10 molecules of a gas randomly whizzing about inside a box.  The Second Law says that all 10 will never be traveling in the exact same direction at the same time.  If they were, you’d get energy from nothing.  They might all strike the north-facing wall at the same time, causing the box to move, instead of an equal number hitting the northern and southern facing walls.

But, just like flipping eight coins and seeing them all land heads, sometimes the above scenario will occur.  It violates the Second Law, and it can happen.  Perpetual motion machines can exist.  They are just very, very rare.  (Imagine a fraction where the denominator is a one followed by as many zeros as you could write before you die.  That number will be bigger than the chance of a water-fueled car working for even several seconds.)

When chemists talk about fuel, they think about diagrams that look roughly like this:


The y axis on this graph is energy, and the x axis is mostly meaningless – here it’s labeled “reaction coordinate,” but you wouldn’t be so far off if you just think of it as time.

For a gasoline powered car, the term “reactants” refers to octane and oxygen.  Combined, these have a higher amount of energy stored in their chemical bonds than an equivalent mass of the “products,” carbon dioxide and water, so you can release energy through combustion.  The released energy moves your car forward.

And there’s a hill in the middle.  This is generally called the “activation barrier” of the reaction.  Basically, the universe thinks it’s a good idea to turn octane and oxygen into CO2 and H2O … but the universe is lazy.  Left to its own devices, it can’t be bothered.  Which is good – because this reaction has a high activation barrier, we rarely explode while refueling at the gas station.

Your car uses a battery to provide the energy needed to start this process, after which the energy of the first reaction can be used to activate the next.  The net result is that you’re soon cruising the highway with nary a care, dribbling water from your tailpipe, pumping carbon into the air.

(Your car also uses a “catalyst” – this component doesn’t change how much energy you’ll extract per molecule of octane, but it lowers the height of the activation barrier, which makes it easier for the car to start.  Maybe you’ve heard the term “cold fusion.”  If we could harness a reaction combining hydrogen molecules to form helium, that would be a great source of power.  Hydrogen fusion is what our sun uses.  This reaction chucks out a lot of energy and has non-toxic byproducts.

But the “cold” part of “cold fusion” refers to the fact that, without a catalyst, this reaction has an extremely steep activation barrier.  It works on the sun because hydrogen molecules are crammed together at high temperature and pressure.  Something like millions of degrees.  I personally get all sweaty and miserable at 80 degrees, and am liable to burn myself when futzing about near an oven at 500 degrees … I’d prefer not to drive a 1,000,000 degree hydrogen-fusion-powered automobile.)

Seriously, I would not want this to be happening beneath the hood of the family ride.

With any fuel source, you can guess at its workings by comparing the energy of its inputs and outputs.  Octane and oxygen have high chemical energies, carbon dioxide and water have lower energies, so that’s why your car goes forward.  Our planet, too, can be viewed as a simple machine.  High frequency (blue-ish) light streams toward us from the sun, then something happens here that increases the order of molecules on Earth, after which we release a bunch of low-frequency (red-ish) light.

(We release low-frequency “infrared” light as body heat – night vision goggles work by detecting this.)

Our planet is an order-creating machine fueled by changing the color of photons from the sun.

A water-fueled car is impractical because other molecules that contain hydrogen and oxygen have higher chemical energy than an equivalent mass of water.  There’s no energy available for you to siphon away into movement.

If you were worried that major oil companies are conspiring against you by hiding the existence of water-fueled cars, you can breathe a sigh of relief.  But don’t let yourself get too complacent, because these companies really are conspiring against you.  They’re trying to starve your children.

On ‘The Overstory.’

On ‘The Overstory.’

We delude ourselves into thinking that the pace of life has increased in recent years.  National news is made by the minute as politicians announce their plans via live-televised pronouncement or mass-audience short text message.  Office workers carry powerful computers into their bedrooms, continuing to work until moments before sleep.

But our frenzy doesn’t match the actual pace of the world.  There’s a universe of our own creation zipping by far faster than the reaction time of any organism that relies on voltage waves propagating along its ion channels.  Fortunes are made by shortening the length of fiberoptic cable between supercomputer clusters and the stock exchange, improving response times by fractions of a second.  “Practice makes perfect,” and one reason the new chess and Go algorithms are so much better than human players is that they’ve played lifetimes of games against themselves since their creation.

640px-IFA_2010_Internationale_Funkausstellung_Berlin_18We can frantically press buttons or swipe our fingers across touch screens, but humans will never keep up with the speed of the algorithms that recommend our entertainment, curate our news, eavesdrop on our conversations, guess at our sexual predilections, condemn us to prison

And then there’s the world.  The living things that have been inhabiting our planet for billions of years – the integrated ecosystems they create, the climates they shape.  The natural world continues to march at the same stately pace as ever.  Trees siphon carbon from the air as they grasp for the sun, then fall and rot and cause the Earth itself to grow.  A single tree might live for hundreds or thousands of years.  The forests in which they are enmeshed might develop a personality over millions.

Trees do not have a neural network.  But neither do neurons.  When simple components band together and communicate, the result can be striking.  And, as our own brains clearly show, conscious.  The bees clustering beneath a branch do not seem particularly clever by most of our metrics, but the hive as a whole responds intelligently to external pressures.  Although each individual has no idea what the others are doing, they function as a unit.

Your neurons probably don’t understand what they’re doing.  But they communicate to the others, and that wide network of communication is enough.

Root_of_a_TreeTrees talk.  Their roots intertwine – they send chemical communiques through symbiotic networks of fungal mycelia akin to telephones.

Trees talk slowly, by our standards.  But we’ve already proven to ourselves that intelligence could operate over many orders of temporal magnitude – silicon-based AI is much speedier than the chemical communiques sent from neuron to neuron within our own brains.  If a forest thought on a timescale of days, months, or years, would we humans even notice?  Our concerns were bound up in the minute by minute exigencies of hunting for food, finding mates, and trying not to be mauled by lions.  Now, they’re bound up in the exigencies of making money.  Selecting which TV show to stream.  Scoping the latest developments of a congressional race that will determine whether two more years pass without the slightest attempt made to avoid global famine.

In The Overstory, Richard Powers tries to frame this timescale conflict such that we Homo sapiens might finally understand.  Early on, he presents a summary of his own book; fractal-like, this single paragraph encapsulates the entire 500 pages (or rather, thousands of years) of heartbreak.

image (2)He still binges on old-school reading.  At night, he pores over mind-bending epics that reveal the true scandals of time and matter.  Sweeping tales of generational spaceship arks.  Domed cities like giant terrariums.  Histories that split and bifurcate into countless parallel quantum worlds.  There’s a story he’s waiting for, long before he comes across it.  When he finds it at last, it stays with him forever, although he’ll never be able to find it again, in any database.  Aliens land on Earth.  They’re little runts, as alien races go.  But they metabolize like there’s no tomorrow.  They zip around like swarms of gnats, too fast to see – so fast that Earth seconds seem to them like years.  To them, humans are nothing but sculptures of immobile meat.  The foreigners try to communicate, but there’s no reply.  Finding no signs of intelligent life, they tuck into the frozen statues and start curing them like so much jerky, for the long ride home.

Several times while reading The Overstory, I felt a flush of shame at the thought of how much I personally consume.  Which means, obviously, that Powers was doing his work well – I should feel ashamed.    We are alive, brilliantly beautifully alive, here on a magnificent, temperate planet.  But most of us spend too little time feeling awe and too much feeling want.  “What if there was more?” repeated so often that we’ve approached a clear precipice of forever having less.

In Fruitful Labor, Mike Madison (whose every word – including the rueful realization that young people today can’t reasonably expect to follow in his footsteps – seems to come from a place of earned wisdom and integrity, a distinct contrast from Thoreau’s Walden, in my opinion) asks us to:

image (3)Consider the case of a foolish youth who, at age 21, inherits a fortune that he spends so recklessly that, by the age of 30, the fortune is dissipated and he finds himself destitute.  This is more or less the situation of the human species.  We have inherited great wealth in several forms: historic solar energy, either recent sunlight stored as biomass, or ancient sunlight stored as fossil fuels; the great diversity of plants and animals, organized into robust ecosystems; ancient aquifers; and the earth’s soil, which is the basis for all terrestrial life.  We might mention a fifth form of inherited wealth – antibiotics, that magic against many diseases – which we are rendering ineffective through misuse.  Of these forms of wealth that we are spending so recklessly, fossil fuels are primary, because it is their energy that drives the destruction of the other assets.

What we have purchased with the expenditure of this inheritance is an increase in the human population of the planet far above what the carrying capacity would be without the use of fossil fuels.  This level of population cannot be sustained, and so must decline.  The decline could be gradual and relatively painless, as we see in Japan, where the death rate slightly exceeds the birth rate.  Or the decline could be sudden and catastrophic, with unimaginable grief and misery.

In this context, the value of increased energy efficiency is that it delays the inevitable reckoning; that is, it buys us time.  We could use this time wisely, to decrease our populations in the Japanese style, and to conserve our soil, water, and biological resources.  A slower pace of climate change could allow biological and ecological adaptations.  At the same time we could develop and enhance our uses of geothermal, nuclear, and solar energies, and change our habits to be less materialistic.  A darker option is to use the advantages of increased energy efficiency to increase the human population even further, ensuring increasing planetary poverty and an even more grievous demise.  History does not inspire optimism; nonetheless, the ethical imperative remains to farm as efficiently as one is able.

The tragic side of this situation is not so much the fate of the humans; we are a flawed species unable to make good use of the wisdom available to us, and we have earned our unhappy destiny by our foolishness.  It is the other species on the planet, whose destinies are tied to ours, that suffer a tragic outcome.

Any individual among us could protest that “It’s not my fault!”  The Koch brothers did not invent the internal combustion engine – for all their efforts to confine us to a track toward destitution and demise, they didn’t set us off in that direction.  And it’s not as though contemporary humans are unique in reshaping our environment into an inhospitable place, pushing ourselves toward extinction.

Heck, you could argue that trees brought this upon themselves.  Plants caused climate change long before there was a glimmer of a chance that animals like us might ever exist.  The atmosphere of the Earth was like a gas chamber, stifling hot and full of carbon dioxide.  But then plants grew and filled the air with oxygen.  Animals could evolve … leading one day to our own species, which now kills most types of plants to clear space for a select few monocultures.

As Homo sapiens spread across the globe, we rapidly caused the extinction of nearly all mega-fauna on every continent we reached.  On Easter Island, humans caused their own demise by killing every tree – in Collapse, Jared Diamond writes that our species’ inability to notice long-term, gradual change made the environmental devastation possible (indeed, the same phenomenon explains why people aren’t as upset as they should be about climate change today):

image (4)We unconsciously imagine a sudden change: one year, the island still covered with a forest of tall palm trees being used to produce wine, fruit, and timber to transport and erect statues; the next year, just a single tree left, which an islander proceeds to fell in an act of incredibly self-damaging stupidity. 

Much more likely, though, the changes in forest cover from year to year would have been almost undetectable: yes, this year we cut down a few trees over there, but saplings are starting to grow back again here on this abandoned garden site.  Only the oldest islanders, thinking back to their childhoods decades earlier, could have recognized a difference. 

Their children could no more have comprehended their parents’ tales of a tall forest than my 17-year-old sons today can comprehend my wife’s and my tales of what Los Angeles used to be like 40 years ago.  Gradually, Easter Island’s trees became fewer, smaller, and less important.  At the time that the last fruit-bearing adult palm tree was cut, the species had long ago ceased to be of any economic significance.  That left only smaller and smaller palm saplings to clear each year, along with other bushes and treelets. 

No one would have noticed the falling of the last little palm sapling.

512px-Richard_Powers_(author)Throughout The Overstory, Powers summarizes research demonstrating all the ways that a forest is different from – more than – a collection of trees.  It’s like comparing a functioning brain with neuronal cells grown in a petri dish.  But we have cut down nearly all our world’s forests.  We can console ourselves that we still allow some trees to grow – timber crops to ensure that we’ll still have lumber for all those homes we’re building – but we’re close to losing forests without ever knowing quite what they are.

Powers is furious, and wants for you to change your life.

You’re a psychologist,” Mimi says to the recruit.  “How do we convince people that we’re right?”

The newest Cascadian [a group of environmentalists-cum-ecoterrorists / freedom fighters] takes the bait.  “The best arguments in the world won’t change a person’s mind.  The only thing that can do that is a good story.”

On Syria, and the complexity of causality.

On Syria, and the complexity of causality.

Approximately one thousand years ago, the Syrian poet Abu Al-Ala Al-Ma’arri wrote:


God help us, we have sold our souls, all that was best,

To an enterprise in the hands of the Receiver.

We’ve no dividends, or rights, for the price we paid.

Yet should our wills choose between this corrupt business

And a paradise to come, rest assured they’d want


The world we have now.


birds(This was translated by Abdullah Al-Udhari and George Wightman for Birds through a Ceiling of Alabaster, a collection of ancient poetry from the Middle East.)

Many of our choices, moment to moment, are saddling us with a rotten deal.  We can often see how to make the world better.  “A paradise to come” might be heaven, but it could also be a more perfect world here on Earth.

If we were starting from scratch, it would be easy.


While wrapping packages at Pages to Prisoners recently, I told another volunteer about my essay on the link between misogyny and the plow.  Sexual dimorphism in Homo sapiens is minor enough that, if we were like other primate species, we shouldn’t have much gender inequality.  Many hunter-gatherer societies that survived until modern times were relatively egalitarian.  And women have been miserably oppressed in cultures that adopted the plow, a farming tool that magnifies the differences between human physiques.

But I had to admit, afterward, that, like all explanations that purport a single cause for something so complicated, my claim was wrong.  There seems to be a correlation between the introduction of the plow and myth-making that led to worlds like our own – but there were surely many other factors.

SphcowThe world is complex.  In physics and economics, the goal is often to propose a simplified model that captures something of the world – the difference between otherwise equivalent cultures that either adopted plowing or did not, the difference between otherwise equivalent societies where GDP growth is larger than the rate of return of investments, or smaller – and hope that most of the omitted detail really was expendable.

Which brings us to Syria.


syria_tmo_2011210Like many environmentalists, I’ve commented on the link between the horrors in Syria and climate change.  Human activities – primarily in nations that experienced a huge leap in living standards during the industrial revolution – have released long-trapped carbon dioxide into the atmosphere.  This has caused a small increase in global temperatures, but can cause a large change in the climate of any particular region of the planet.  Areas that once supported many people become suddenly less habitable.

Like Syria.  The country plunged into drought, which led to widespread food insecurity, which made the violence worse.

That much seems true, but it’s certainly not the whole truth.  The violence was already there.

Al_Assad_familyWhile Syria was ruled by the Assads, there were constant human rights abuses.  Their punishment for a 19-year-old student who joined the Syrian Communist Party and expressed dissatisfaction with his country’s political regime?  The student was imprisoned for sixteen years.

After his release, the now middle-aged Yassin al-Haj Saleh still disliked his government.  Somehow those sixteen years did not convince him of the errors in his youthful ways.  He married a fellow political activist and continued to advocate for change.

Unfortunately, activism like theirs contributed to Syria’s descent into nightmare.  You should read Lindsey Hilsum’s “War of All Against All,” in which she reviews Saleh’s recent essay collection alongside three other books about the tragedy.

Saleh wrote that:

International_Mine_Action_Center_in_Syria_(Aleppo)_12It never occurred to us that there could be a more dangerous threat to their lives than the regime’s bombs.  What bestows a particularly tragic status on this abduction is that it was an outcome of our own struggle, and that we ourselves had made this horrible incident possible.

This sentiment is painfully elaborated by Hilsum:

The sentence bears rereading: so terrible is the situation in Syria that one of the region’s most long-standing and fervent critics, a man who has dedicated his whole life to fighting the Assads, father and son, is forced to wonder if it would have been better not to rebel at all.  The author’s head may have remained clear while his heart was breaking, but the carefully modulated prose of these essays does not provide the whole story.  How can we understand the Syrian revolution unless … we consider in … depth how it feels to blame yourself for your wife’s disappearance and probable death?

The writer’s personal tragedy reveals him as an authentic voice trying to understand how the genuine, progressive revolt he supported went so horribly wrong.

The regime was awful, imprisoning and torturing children for years at a time.  Student-led protests eventually led to a retreat by the regime, but then quasi-religious fanatics claimed vast swaths of the country.  They kept the old regime’s torture and arbitrary imprisonment, and added public execution.  U.S. intervention arrived late and couldn’t root out the deeply-infiltrated jihadists.

Hilsum writes that “An older woman we met might have been forgiven for cursing both sides: ISIS had expropriated her house, she said, and then the Americans had bombed it.


While reading Hilsum’s piece, I felt a twinge of guilt.  Yes, climate change exacerbated the tragedy, but the chaos in Syria was already a tragedy.  It’s heartlessly trivializing to imply that there could be a simple explanation for such a complex, horrible thing.  I was wrong to blithely write what I did.

Plows don’t oppress women, people did.  (Which sounds unfortunately reminiscent of “guns don’t kill people,” because guns do, they potentiate far more killing than would be possible without them.)

Climate change didn’t murder millions of Syrians.  But it made an awful situation worse.

On the sounds of aberrant ecosystems

On the sounds of aberrant ecosystems

When I was ten years old, I read about a new card game, Magic, in the local newspaper. The article described the basic conceit of the game – you are a wizard who must conquer territory to power your spells – and a few of the cards – the article mentioned Giant Growth, which it said “is just a big rat.”

squeeI was enthralled. It took about a year of searching before I found a place to buy cards, but eventually the local hobby shop would siphon away all my babysitting money.

My favorite card was Squee – a goblin who keeps returning from the dead. Squee was pretty powerful when combined with Survival of the Fittest, which lets you trade your weak creatures for more powerful monsters, and Goblin Bombardment, which lets you fling creatures at your enemies. But I loved Squee disproportionately to his power. This little monster, swimming in his robes, is blessed with infinite renewal … just like humanity’s original misconception of nature.


Before the industrial revolution, no single generation could change the world enough to prove this notion wrong. Humans cut down trees, but there are so many trees and more grow all the time. Humans wash their clothes or defecate in the river, but new clean water flows. Humans hunt game and catch fish, but – as long as you make a god-placating sacrifice every now and then – there will always be more animals to eat.


Jared Diamond remarks upon our inability to notice slow changes in Collapse, his (tragically relevant) account of the factors that cause civilizations to die:

collapseI suspect that landscape amnesia provided part of the answer to my UCLA students’ question, “What did the Easter Islander who cut down the last palm tree say as he was doing it?” We unconsciously imagine a sudden change: one year, the island still covered with a forest of tall palm trees being used to produce wine, fruit, and timber to transport and erect statues; the next year, just a single tree left, which an islander proceeds to fell in an act of incredibly self-damaging stupidity. Much more likely, though, the changes in forest cover from year to year would have been almost undetectable: yes, this year we cut down a few trees over there, but saplings are starting to grow back again here on this abandoned garden site. Only the oldest islanders, thinking back to their childhoods decades earlier, could have recognized a difference. Their children could no more have comprehended their parents’ tales of a tall forest than my 17-year-old sons today can comprehend my wife’s and my tales of what Los Angeles used to be like 40 years ago. Gradually, Easter Island’s trees became fewer, smaller, and less important. At the time that the last fruit-bearing adult palm tree was cut, the species had long ago ceased to be of any economic significance. That left only smaller and smaller palm saplings to clear each year, along with other bushes and treelets. No one would have noticed the falling of the last little palm sapling.

It probably took several generations before trees were expunged from Easter Island. As Homo sapiens migrated into Europe, the Americas, and Australia, most large animals were driven to extinction, including all other species of humans. The Homo sapiens involved probably had no idea what they were doing. Each generation would see some decline in the abundance of an animal, but nothing to worry about. The last few deaths would occur among a people who had no idea what was lost.

Moby_Dick_p510_illustrationIn Herman Melville’s Moby Dick, the narrator considers whether Leviathan can long endure so wide a chase, and so remorseless a havoc; whether he must not at last be exterminated from the waters, and the last whale, like the last man, smoke his last pipe, and then himself evaporate in the final puff.

The narrator promptly dismisses this fear. Yes, buffalo were driven to extinction in America, but only because a single man could slaughter thousands. At that time, the concerted efforts of many were needed to kill each whale.

Even so, the whales seemed to be disappearing. But the narrator – so obsessed with the hunt that he hardly notices when he’s deluding himself – rejects the evidence:

10838762315_69b85f2e8a_zAnd equally fallacious seems the conceit, that because the so-called whale-bone whales no longer haunt many grounds in former years abounding with them, hence that species also is declining. For they are only being driven from promontory to cape; and if one coast is no longer enlivened with their jets, then, be sure, some other and remoter strand has been very recently startled by the unfamiliar spectacle.

Sperm whale populations plummeted. Gestation lasts over a year; mothers care for their young for a decade; males sexually mature at eighteen and aren’t fully grown until their fifties. They could not reproduce as quickly as we could kill them.


Most whales are extremely social, and communicate in ways that humans don’t yet understand. Their songs show signs of local culture, as do their hunting strategies. Those centuries of “harvest” may have caused several dialects or languages to be lost.

Sperm whale populations have since recovered. But several other species of whale are endangered. Our discarded plastics waft through the sea. The waters are becoming sufficiently acidic to kill off coral reefs.

The ocean is not nearly so infinite as we humans once thought it to be.


Recently, technological progress has become so fast that the world changes noticeably within single generations. For tens of thousands of years, each human’s life resembled that of the parents. Even after some humans developed an agrarian lifestyle and began curating the evolution of favored plants and animals, the world changed slowly. Over many generations, Zea mays went from a useless scruffy grass to buxom-kernaled ears of corn. But, over the course of any single farmer’s life, the corn gnawed during senescence could probably be mistaken for the corn of youth.

Whereas my grandmother’s cellphone / camera / computer combo looks radically different from any of the bulky, ineffectual devices available when she was young. And my parents’ generation – whose lives spanned the development of modern agricultural practices – has seen a precipitous fall in all non-human animal life. In The Moth Snowstorm, Michael McCarthy describes this decline:

The_Moth_Snowstorm_for_web_df271fb2-a6f7-4703-9f9a-23ea2dbb7f70_1024x1024It had been the most powerful of all the manifestations of abundance, this blizzard of insects in the headlights of cars, this curious side effect of technology, this revelatory view of the natural world which was only made possible with the invention of the motor vehicle. It was extraordinary; yet even more extraordinary was the fact that it had ceased to exist. Its disappearance spoke unchallengeably of a completely unregarded but catastrophic crash in Britain of the invertebrate life which is at the basis of so much else. South Korea may have destroyed Saemangeum, and China may have destroyed its dolphin, but my own country has wrecked a destruction which is just as egregious; in my lifetime, in a process that began in the year I was born, in this great and merciless thinning, it has obliterated half its living things, even though the national consciousness does not register it yet. That has been my fate as a baby boomer: not just to belong to the most privileged generation which ever walked the earth, but, as we can at last see now, to have my life parallel the destruction of the wondrous abundance of nature that still persisted in my childhood, the abundance which sang like nothing else of the force and energy of life and could be witnessed in so many ways, but most strikingly of all in the astonishing summer night display in the headlight beams, which is no more.

Cleaning splattered bugs off a windshield doesn’t sound like fun; drivers rarely have to do this anymore. But … we now have only a tenth as many insects as we did during the 1980s. Which means a tenth as much food for birds: their populations are falling too. Birds breed more slowly now, for lack of food, and many are killed off because our world sports unnaturally high population densities of predatory cats.

And that’s just the decline since 1989. Over the course of McCarthy’s life, insect populations may have fallen by 95% or more. And, because of the “landscape amnesia” described by Diamond above, it’s difficult for anyone born later to even realize what’s been lost. We assume that whatever world we’ve been born into is normal.


Last night, Uncle Max woke me to go outside at 3 a.m. Afterward, I lay in bed listening to the birds singing.

Fewer birds sang at night when I was growing up. But they are adapting to our world. Our streetlights shine all the time, and our cities, during the day, are so loud that their songs cannot be heard. Humanity’s persistent racket is infiltrating even the most secluded corners of the world.

From Ula Chrobak’s article on noise pollution:

noiseSome plants need silence for seed dispersal—revving cars can scare away rodents that might otherwise do the job. Animals need silence to hear predators approaching or to communicate with their mates: A bird whose song would normally travel 100 meters would, with a 10-fold increase in noise, have its melody stifled to a 10-meter radius. “In so many landscapes, both people and other organisms are living in shrunken perceptual worlds,” says [ecologist] Clinton Francis.

In The Songs of Trees, David Haskell describes the way our forests should sound – the natural world has its own rhythms, its own music. In the following passage he listens in the Amazon:

songsoftreesA tinamou sings the forest’s vespers. Although this turkey-size relative of the emu is seldom seen, its melodies accent every dusk. The sound is the work of a silversmith, pure tones that the artist melts and crafts into ornament. The inflections and timbre of the Andean quena flute are surely inspired by the songs of these birds. In the understory the dark is comprehensive, but here in the ceibo crown, dusk lingers another thirty minutes, the orange gray western light of sunset reaching us unobstructed as we hear the tinamou’s song.

As the light drains, bromeliad frogs spasm chuckles and grunts from aerial ponds. They call for five or more minutes, then cut to silence. Any sound will set them off again: a stray frog call, a human voice, the bleat of a roosting bird trodden by a companion. Three species of owl join the frogs. Crested owls punch regular groans from below, keeping in touch with mates, neighbors, and the youngster that the pair have hidden in the low branches of an Inga tree. The spectacled owl’s repeated low, rubbery calls wobble around their crooked axis like a badly aligned tire. A distant tawny screech owl sings a high to-to-to-to, an endless, jabbing ellipsis. Insects pulse high drills, clear, sweeping chirps, saws, and tinkles. Monkeys and parrots whose sounds dominate the day have dozed away. The upper leaves of the ceibo chuff in the sharp gusts that accompany the sunset, then the wind eases and stillness comes to the tree.

But these forests, too, are threatened. The ancient trees are cut down and the music wanes. One after another, pockets of nature are forgetting how to speak. Again from Haskell:

In the center of town, Quichua men in suits work with and within the local government. The central, national government hurts and kills the ceibo mother tree, cutting her away piece by piece. Even conservation programs encourage people to cut away the trees. We lose our medicines and hunting. State-driven conservation erodes the indigenous community. Without intact territory, owned and managed by the indigenous community, the forest falls into incoherence, the community dies.


The evidence of harm is all around us. Our world sounds wrong, tastes wrong, smells wrong. We’re scraping too few bugs off our windshields after long drives.

And, if we don’t act, our children won’t feel that they need to. A hot, loud planet will feel just as normal to them as the planet we inherited felt to us.
