On dangerous air & the damnation of cyanobacteria.

On dangerous air & the damnation of cyanobacteria.

During the acute phase of the Covid-19 pandemic, I kept thinking of Margarita Engle’s poem “More Dangerous Air.” The title seemed particularly resonant, and its a beautiful poem about growing up in an atmosphere of fear.

Newsmen call it the Cuban Missile Crisis.

Teachers say it’s the end of the world.

Engle documents the way we might flail, attempting to protect ourselves & our loved ones. We know enough to be afraid; we don’t yet know enough to be safe.

Early in the pandemic, people left their groceries on the front steps for days before bringing the bags inside. A year in, we were still needlessly scrubbing surfaces with toxic chemicals.

#

During the missile crisis, school children practiced fire drills, earthquake drills, tornado drills, air raid drills. (They didn’t yet need the contemporary era’s most awful: the active shooter drills.)

Hide under a desk.

Pretend that furniture is enough

to protect us against perilous flames.

Radiation. Contamination. Toxic breath.

The blasts are dangerous. But warfare with atomic weapons is different from other forms of violence. A bomb might kill you, suddenly; the poisoned air might kill you, slowly; the poisoned ground might maim generations yet unborn.

Each air-raid drill is sheer terror,

but some kids giggle.

They don’t believe that death

is real.

Radiation is invisible. Marie Curie didn’t know that it would kill her. Rosalind Franklin didn’t know that it would kill her.

We know, now. At least, some of us do.

Others – including a perilously large cadre of politicians – still think we ought to stockpile a behemoth nuclear arsenal.

Viruses are invisible. And they act slowly. Breathe in an invisible virus; a week later, you might begin to cough; three weeks later, your cough might worsen; a month after that seemingly innocuous breath in which you sucked a microscopic package of genetic code into your lungs, you might be in the hospital, or worse.

Connecting an eventual death to that first dangerous breath is actually a tricky cognitive feat! The time lag confuses us. It’s much easier for human minds to draw conclusions about closely consecutive events – a vaccine followed within hours or days by fever or heart problems.

#

Greenhouse gases are also invisible. If we drive past a power plant, we might see plumes rising from the towers, but we can’t see poison spilling from our cars, our refrigerators, our air conditioners, our meals. This is just good food on a plate! It doesn’t look like danger.

But we are changing the air, dramatically, in ways that might poison us all. Or – which is perhaps worse – in ways that might not affect us so much, but might make this planet inhospitable to our unborn grandchildren. Perhaps we will be fine. It’s humans born twenty years from now, or fifty years from now, who will suffer more.

#

Each individual can take action. You, as an individual, could fly less, buy less, eat plants.

And yet.

You, as an individual, can only do so much.

When I hide under my frail school desk,

my heart grows as rough and brittle

as the slab of wood

that fails to protect me

from reality’s

gloom.

#

We aren’t the first. Go outside and look around – the vibrant bursts of summer green are delightfully entrancing.

Our minds are plastic things – we make ourselves through the ways we live – but certain scripts were sculpted by our ancestry. Over hundreds of millions of years, the bearers of certain types of brains were more likely to be successful in life.

Creatures like us – who need air to breath, water to drink, shelter from sun and cold – often feel an innate love for the way summer light plays over a heady mix of blue and green.

We need all that green. The plants, the trees, the algae: for humans to survive the climate crisis we’ve been making, we’re depending on them. We need them to eat carbon dioxide from the air, and drink in hydrogen atoms from water, and toss back oxygen for us to breathe.

We’ve been poisoning the air, and they might save us.

Which is ironic, in a way. Because all that green – they wrought our planet’s first global devastation.

Saving us all this time would be like a form of penance.

#

Early in our planet’s history, there was very little oxygen in the air. Which was a good thing for the organisms living then! Oxygen is a very dangerous molecule. When we fall apart with age, it’s largely because “oxidative damage” accumulates in our cells. When grocery stores market a new type of berry as a “superfood,” they often extol its abundance of “antioxidants,” small molecules that might protect us from the ravages of oxygen.

The first living organisms were anaerobic: they did not need, and could not tolerate, oxygen. They obtained energy from sulfur vents or various other chemicals.

But then a particular type of bacteria – cyanobacteria – evolved a way to eat air, pulling energy from sunlight. This was the precursor to modern photosynthesis. Cyanobacteria began to fill the air with (poisonous!) oxygen as waste.

Many years passed safely, though. There was abundant iron then, on land and in the seas – iron drew down oxygen to rust.

Approximately two billion years passed without incident. All that iron buffered our planet’s atmosphere! It must have seemed as though the cyanobacteria could excrete a nearly infinite amount!

But then they reached a tipping point. The iron had all become iron oxides. The concentration of oxygen in the air rose dramatically. This hyper-reactive poison killed almost everything alive.

#

Perhaps cyanobacteria were punished for what they’d done. By filling the world with oxygen, they enabled the evolution of organisms with higher metabolisms. Creatures who lived faster, shorter lives, turbocharged by all that dangerous air. And these creatures – our forebears – nearly grazed their enablers out of existence.

Cyanobacteria were once masters of the universe. Then they were food.

And they were imprisoned within the cells of plants. Look up at a tree – each green leaf is a holding cell, brimming with cyanobacteria who are no longer free to live on their own. Grasses, ferns, flowers – every photosynthetic cell home to perhaps dozens of chloroplasts, the descendants of those who caused our planet’s first mass extinction.

A few outlaws linger in the ocean. Some cyanobactera still pumping oxygen into the air, the lethal poison that’s gulped so greedily by human lungs. Their lethal poison now enables our growth, our flourishing, our reckless abasement of the world.

And we are poisoning the air in turn, albeit in a very different way. In our quest to use many years’ stored sunlight each year, we dig up & burn the subterranean remnants of long-dead plants. The prison cells in which cyanobacteria once lived and died, entombed for millions of years within the earth, now the fuel for our own self-imposed damnation. The concentration of carbon dioxide in the air is slowly rising. Our atmosphere is buffered; for a while, our world will seem unchanged. Until, suddenly, it doesn’t.

Some species, surely, will survive. Will thrive in the hotter, swingier, stormier world we’re making.

It likely won’t be us.

On apocalypse clocks.

On apocalypse clocks.

The world is complicated. There’s so much information out there, so much to know. And our brains are not made well for knowing much of it.

I can understand numbers like a dozen, a hundred. I can make a guess at the meaning of a thousand. Show me a big gumball machine and ask me to guess how many gumballs are in it, maybe I’ll guess a thousand, a few thousand.

But numbers like a million? A billion? A trillion? These numbers are important, I know. These numbers might be the population of cities, or of planets, or of solar systems. These numbers might be the ages of species or planets. These numbers might be how many stars are in the sky, or how many stars in the sky might harbor life.

These numbers don’t mean much to me.

I don’t think the problem is just my brain. I’m fairly good with numbers, relative to the average human. It’s been years since I’ve sat in a math class, but I can still do basic integrals and derivatives in my head.

Yet I can’t understand those big numbers. They don’t feel like anything to me.

So we make graphs. Charts. We try to represent information in ways that our meager human brains can grasp.

A good chart can be a revelation. Something that seemed senseless before is now made clear.

#

An apocalypse is a revelation. The word “apocalypse” means lifting the veil – apo, off; kalyptein, conceal. To whisk away the cover and experience a sudden insight.

An illustration that depicts information well allows numbers to be felt.

Often, though, we illustrate information and we do it poorly.

The scientific method is gorgeous. Through guesswork, repetition, and analysis, we can learn about our world.

But science is never neutral. We impart our values by the questions we choose to ask, by the ways we choose to interpret the world’s ever-oblique answers.

#

Geological time is often depicted as a clock. A huge quantity of time, compressed down into a 24-hour day. Often, this is done with the ostensible goal of showing the relative unimportance of humans.

Our planet has been here for a day, and humans appear only during the final two minutes!

Unfortunately, this way of depicting time actually overemphasizes the present. Why, after all, should the present moment in time seem so special that it resides at midnight on our clock?

The present feels special to us because we’re living in it. From a geological perspective, it’s just another moment.

#

In Timefulness, geologist Marcia Bjornerud writes:

Geologic textbooks invariably point out (almost gleefully) that if the 4.5-billion-year story of the Earth is scaled to a 24-hour day, all of human history would transpire in the last fraction of a second before midnight.

But this is a wrongheaded, and even irresponsible, way to understand our place in Time. For one thing, it suggests a degree of insignificance and disempowerment that not only is psychologically alienating but also allows us to ignore the magnitude of our effects on the planet in that quarter second.

And it denies our deep roots and permanent entanglement with Earth’s history; our specific clan may not have shown up until just before the clock struck 12:00, but our extended family of living organisms has been around since at least 6 a.m.

Finally, the analogy implies, apocalyptically, that there is no future – what happens after midnight?

#

Timefulness is a lovely book, but Bjornerud does not present a corrected clock.

And so I lay in bed, thinking. How could these numbers be shown in a way that helped me to understand our moment in time?

I wanted to fix the clock.

#

The first midnight is easy – the birth of our sun. A swirling cloud of gas condenses, heating as gravity tugs the molecules into more and more collisions. Nuclear fusion begins.

Gravity tugs molecules inward, nuclear explosions push them outward. When these are balanced, our sun exists. Twelve o’clock.

Two minutes later, our planet is born. Metal and water and dust become a big rock that keeps swirling, turning, as it orbits the sun. It’s warmed, weakly, by light from the sun – our star shone dimly then, but shines brighter and brighter every day.

Our sun earns low interest – 0.9% each hundred million years, hotter, brighter. But wait long enough, and a low interest is enough.

Someday, shortly before it runs out of fuel, our sun will be blinding.

By 12:18 a.m., there is life on Earth. We’ve found fossils that many billions of years old.

And at 7:26 p.m., there will be no more life. Our sun will have become so bright that its blinding light evaporates all the oceans. The water will boil so hot that it will be flung into space. The Earth will be a rocky desert, coated perhaps in thick clouds of noxious gas.

Currently, it’s 10:58 a.m.

The dinosaurs appeared 35 minutes ago. 9.5 minutes ago, all of them died (except the ancestors of our birds).

Humans appeared 1 minute ago.

#

So, we have 3.5 billion years remaining – another 8.5 hours on our clock – before we have to migrate to the stars.

Humans certainly can’t persist forever. Empty space is stretching. Eventually, the whole universe will be dark and cold, which each speck of matter impossibly far from every other.

But our kind could endure for a good, long while. Scaled to the 24-hour day representing the lifespan of our sun, we still have another 300 years before the universe goes dark.

So many stories could fit into that span of time.

#

It’s 10:58 a.m., and life on Earth has until 7:26 p.m.

Humans crept down from trees, harnessed fire, invented writing, and built rockets all within a single minute. Life moves fast.

Quite likely, life from Earth will reach the stars.

But it needn’t be us.

The dinosaurs were cool. They didn’t make it.

We naked apes are pretty cool, too. I love our cave drawings, art museums, psychedelic street art. Our libraries. But we’ve also made prodigious mounds of trash. We’re pouring plumes of exhaust into the sky as we ship giant flatscreen televisions from place to place.

We burn a lot of fuel for the servers that host our websites.

We humans aren’t the first organisms to risk our own demise by pumping exhaust into the atmosphere. The industrial revolution was fueled by ancient plants – our engines burn old sunlight. But many microbes are happy to eat old sunlight, too. These microbes also pump carbon dioxide into the air. They’ve warmed our planet many times before – each time the permafrost thawed, microbes went to town, eating ancient carbon that had been locked up in the ice.

Foolish microbes. They made the Earth too hot and cooked themselves.

Then again, the microbes may have more modest goals than us humans. We’ve found no fossils suggesting that the microbes tried to build spaceships.

For our endeavors, we’ve benefited from a few thousand years of extremely stable, mild climate.

We still have 8.5 hours left to build some spaceships, but a thirty second hot squall at 10:59 a.m. would doom the entire project.

So much time stretches out in front of us. We could have a great day. We, in continuation of the minute of humans who preceded us, and continued by the seconds or minutes or hours of humans who will be born next.

We shouldn’t let our myopic focus on present growth fuck up the entire day.

Honestly? My children are four and six. I’d be so disappointed if I took them for a hike and they guzzled all their water, devoured all their snacks, within the first minute after we left our house.

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 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.”
