When I was a child, my parents gave me a toy walrus to sleep with. While cuddling this walrus, I’d twist my fingers through a small looped tag on its back, until one day I knotted the tag so thoroughly that I cut off my circulation. I screamed; my finger turned blue; my parents rushed in and wanted to cut off the tag.
“No!” I apparently screamed. “The soft tag is the best part!”
I continued to refuse their help until they offered a compromise, merely slicing the loop in half so we could save my throbbing finger and prevent any future calamity.
I continued to sleep with that toy walrus until I was midway through high school. As I fell asleep, my parents would sometimes peer inside my bedroom and see me lying there, eyes closed, breath slow, my fingers gently stroking that soft tag.
Yes, kids with autism are sometimes quite particular about sensory stimulation. But I am not alone! Baby monkeys also love soft fabric.
So do their mothers.
After biologist Margaret Livingstone published a research essay, “Triggers for Mother Love,” animal welfare activists and many other scientists were appalled. In the essay, Livingstone casually discusses traumatic ongoing experiments in which hours-old baby monkeys are removed from their mothers. The babies are then raised in environments where they never glimpse anything that resembles a face, either because they’re kept in solitary confinement and fed by masked technicians or because the babies’ eyes are sutured shut.
After the babies are removed from their mothers, Livingstone offers the mothers soft toys. And the mothers appear to bond with these soft toys. When one particular baby was returned to its mother several hours later, Livingstone writes that:
“The mother looked back and forth between the toy she was holding and the wiggling, squeaking infant, and eventually moved to the back of her enclosure with the toy, leaving the lively infant on the shelf.”
Although I dislike this ongoing research, and don’t believe that it should continue, I find Livingstone’s essay to be generally compassionate.
Livingstone discusses parenting advice from the early twentieth century – too much touch or physical affection will make your child weak! – that probably stunted the emotional development of large numbers of children. Livingstone expresses gratitude that the 1950s-era research of Harry Harlow – the first scientist to explore using soft toys to replace a severed maternal bond – revealed how toxic these recommendations really were.
Harlow’s research may have improved the lives of many human children.
Harlow’s research intentionally inflicted severe trauma on research animals.
To show that the aftereffects of trauma can linger throughout an animal’s life, Harlow used devices that he named “The Rape Rack” and “The Pit of Despair” to harm monkeys (whom he did not name).
Harlow did not justify these acts by denigrating the animals. Indeed, in Voracious Science and Vulnerable Animals, research-scientist-turned-animal-activist John Gluck describes working with Harlow as both a student and then professorial collaborator, and believes that Harlow was notable at the time for his respect for monkeys. But this was not enough. Gluck writes that:
“The accepted all-encompassing single ethical principle was simple: if considerations of risk and significant harm blocked the use of human subjects, using animals as experimental surrogates was automatically justified.”
“Harlow showed that monkeys could be emotionally destroyed when opportunities for maternal and peer attachment were withheld. He argued that affectionate relationships in monkeys were worthy of terms like love.”
“In his work on learning in monkeys … [he offered] abundant evidence that monkeys develop and evaluate hypotheses during attempts to develop a solution.”
“Everything that Harlow learned from his research declared that monkeys are self-conscious, emotionally complex, intentional, and capable of substantial levels of suffering.”
For my own scientific research, I purchased cow’s brains from slaughterhouses. I used antibodies that were made in the bodies of rabbits and mice who lived (poorly) inside industrial facilities. For my spouse’s scientific research, she killed male frogs to take their sperm.
We’re both vegan.
I’d like to believe that we’d find alternative ways to address those same research questions if we were to repeat those projects today. But that’s hypothetical – at the time, we used animals.
And I certainly believe that there are other ways for Livingstone to study, for instance, the developmental ramifications of autistic children rarely making eye contact with the people around them – without blinding baby monkeys. I believe that Livingstone could study the physiological cues for bonding without removing mothers’ babies (especially since Harlow’s work, from the better part of a century ago, already showed how damaging this methodology would be).
Personally, I don’t think the potential gains from these experiments are worth their moral costs.
But also I recognize that, as a person living in the modern world, I’ve benefited from Harlow’s research. I’ve benefited from the research using mice, hamsters, and monkeys that led to the Covid-19 vaccines. I’ve benefited from innumerable experiments that caused harm.
Livingstone’s particular research might not result in any benefits – a lot of scientific research doesn’t – but unfortunately we can’t know in advance what knowledge will be useful and won’t won’t.
And if there’s any benefit, then I will benefit from this, too. It’s very hard to avoid being helped by knowledge that’s out there in the world.
To my mind, this means I have to atone – to find ways to compensate for some of the suffering that’s been afflicted on my behalf – but reparations are never perfect. And no one can force you to recognize a moral debt.
You will have to decide what any of this means to you.
Several months ago, someone wrote to me for the first time in a few years. A week passed before I saw the message – they’d written to my old Google-hosted email account, and I’ve mostly switched to using Protonmail. So I wrote back using my current address … then heard nothing.
Encountering sudden bouts of radio silence is a common experience for many people in the modern world (I feel so bad for people using dating apps in major cities!), but this can feel particularly triggering for people with autism. Because my brain doesn’t always register social cues that other people notice, my early years were riddled with times when people whom I thought were friends suddenly (from my perspective!) decided that I was awful. I still approach disrupted communication with wariness, assuming that people are angry with me.
Later, though, a friend informed me that messages I send to him are often shunted to his spam folder – perhaps Google generally distrusts “@protonmail” accounts? So I used my old account to write to that first person and asked whether the same thing had happened to our correspondence.
At the beginning of a four-paragraph message, I included a sentence summarizing why I have a new email address: “I have mixed feelings about internet privacy – I worry that a lot of it abets tax evasion & the like – but I like email enough (and dislike the effect of advertising companies like Google and Facebook on our world enough) that I thought I should pay for it.”
This person decided I must be a conspiracy theorist.
The problem is brevity, of course.
With more words, it’s easy to show the harms caused by Swiss privacy laws (apparently a major selling point for Protonmail, which houses its physical servers in Switzerland). In The Hidden Wealth of Nations, French economist Gabriel Zucman calculated how much wealth is hidden from governments worldwide. As translated by Teresa Lavender Fagan, Zucman writes:
The following example shows it in a simple way: let’s imagine a British person who holds in her Swiss bank account a portfolio of American securities — for example, stock in Google.
What information is recorded in each country’s balance sheet? In the United States, a liability: American statisticians see that foreigners hold US equities. In Switzerland, nothing at all, and for a reason: the Swiss statisticians see some Google stock deposited in a Swiss bank, but they see that the stock belongs to a UK resident — and so they are neither assets nor liabilities for Switzerland. In the United Kingdom, nothing is registered, either, but wrongly this time: the Office for National Statistics should record an asset for the United Kingdom, but it can’t, because it has no way of knowing that the British person has Google stock in her Geneva account.
As we can see, an anomaly arises — more liabilities than assets will tend to be recorded on a global level. And, in fact, for as far back as statistics go, there is a “hole”: if we look at the world balance sheet, more financial securities are recorded as liabilities than as assets, as if planet Earth were in part held by Mars. It is this imbalance that serves as the point of departure for my estimate of the amount of wealth held in tax havens globally.
Obviously, including only the final sentiment – It appears as though a large portion of our planet’s wealth is owned by extraterrestrials! – would make Zucman sound absurd. But Zucman’s reasoning is sensible, and it’s awful that approximately 10% of our planet’s wealth – $7.6 trillion in 2013 – is held in secret bank accounts, abetted by various nations’ privacy laws. If that wealth weren’t illegally hidden, fair taxes would let us alleviate a lot of poverty, vaccinate many more people worldwide, build a more just and equitable world.
Brief statements like “Tech companies are siphoning personal data to mind control us!” or “Facebook & YouTube have shut down our functioning government!” would likewise probably sound absurd to someone who hasn’t read Shoshana Zuboff’s The Age of Surveillance Capitalismor similar reporting. Once upon a time, I liked Facebook – it was a great way to share pictures with friends – but I felt horrified when I learned about Facebook’s role in the election of our 45th president. I haven’t logged in to my account since November 2016.
Honestly, though, it’s my fault for assuming that other people have been following these stories. Just because someone is a left-wing academic type doesn’t mean they’ve seen the same news that I have (the personalized filter bubbles that we get stuck inside are yet another reason why I dislike Facebook & Google).
It felt sad to have someone assume the worst of me, but then my spouse cheered me up by rattling off other things I say that sound an awful lot like conspiracy theories when they’re phrased too briefly, like:
I only eat plants because I’m worried my planet’s getting too hot.
I rub this glop all over my face so starlight won’t mutate my DNA.
I put this plastic in my mouth at night to stop my teeth from wandering when I sleep.
The dishwasher won’t wash the dishes unless you wash the dishes before you put them in the dishwasher.
So, I learned something. If there’s not enough time to explain an idea in full, it might be better to say nothing at all.
Header image from a prior essay about Thomas Pynchon’s Gravity’s Rainbow and, yes, a Disney conspiracy to misinform children about the natural world.In brief (apparently I still haven’t learned my lesson), the people making Disney’s 1958 documentary White Wilderness wanted to show lemmings leaping off cliffs into the water, but lemmings don’t actually do this. So the film crew instead used a turntable to fling the little critters to their doom and claimed in a voiceover that it was natural footage.
Mythological heroes of yore – and comic book superheroes today – embody our deepest values. This is what a hero would do. Heracles, Arjuna, and Spiderman learn that great powers bestow equivalent responsibility. Prometheus, Odin, and Deadpool accept suffering as the cost of their attachment to the world. Theseus, Samson, and Punisher wreck violence upon their enemies.
These men are all heroes. They battle monsters. They fight and kill to enforce boundaries.
At times, they reveal themselves to be more monstrous than the monsters.
The Greek hero Theseus has a signature style: he follows the Golden Rule. Do unto others as they would do unto you.
Theseus encounters Club Bearer, a villain who murders people by using a big stick to smash them into the earth. Theseus murders Club Bearer by using a big stick to smash him into the earth.
Theseus encounters Pinebender, a villain who murders people by tying their limbs to the bowed trunks of pine trees. Theseus murders Pinebender by tying his limbs to the bowed trunks of pine trees.
Theseus encounters Sciron, a villain who murders people by kicking them off a cliff when they attempt to wash their feet. Theseus murders Sciron by kicking him off a cliff when he attempts to wash his feet.
And so on.
Theseus, the hero, rids the world of monsters by doing unto monsters precisely what they would do to him.
Then Theseus meets the Minotaur.
The Minotaur – a monster with a human body and bovine head – was born because his mother was unsatisfied with her husband and went to great efforts – constructing a wooden cow costume, etc. – to have sex with a bull instead.
Obviously, this myth was concocted by a man. Many men fear that they’re lousy in bed; many men assume that a larger penis would make them IRRESISTIBLE to women; many men tell stories about “wicked women” turning faithless in the face of someone better endowed.
And – also obviously – in a man’s story, the Minotaur’s monstrous genesis had to be a wicked woman’s fault.
The Minotaur is known to be a monster because he eats humans. The Minotaur’s father imprisoned him inside a giant labyrinth. In an annual ritual, the Minotaur’s father also locks defenseless young people inside the labyrinth. Then the Minotaur eats them.
But Theseus seduces the Minotaur’s fully-human sister, convinces her to give him a secret map to navigate the labyrinth, and then smuggles in a sword during the night. After skulking through the labyrinth, Theseus slays the sleeping Minotaur.
The Minotaur – we recognize him as a monster by his big bovine head. But all bovines only eat plants. It’s actually the monster’s human gullet, stomach, & intestines – the monster’s human appetite – that must be feared. The Minotaur has an herbivorous head but is a meat-eating monstrosity beneath the neck.
During his travels, Theseus has often feasted upon bovine flesh. He’s already mirrored the monstrosity of the Minotaur: eating the other’s people. But inside the labyrinth, Theseus does not devour the Minotaur. This is the only time when Theseus does not strictly mirror the behavior of an enemy.
Which might have revealed too much about the boundaries being policed: Only humans may eat the world.
The fundamental horror – what made all of Theseus’s enemies monstrous – was never about what they’d done, but rather who had done it.
In Jess Zimmerman’s essay collection Women and Other Monsters, she describes the ways that myths are used to define the boundaries of acceptable behavior. A human who eats other animals can be a hero; an animal (or animal-headed entity) who eats humans would be a monster.
Zimmerman offers advice: What should we do when we recognize the hypocrisies in our ancestors’ sacred stories?
For women, the boundaries of acceptability are strict, and they are many. We must be seductive but pure, quiet but not aloof, fragile but industrious, and always, always small. We must not be too successful, too ambitious, too independent, too self-centered – and when we can’t manage all the contradictory restrictions, we are turned into grotesques. Women have been monsters, and monsters have been women, in centuries’ worth of stories, because stories are a way to encode these expectations and pass them on.
We’ve built a culture on the backs of these monstrous women, letting them prop up tired morals about safety and normalcy and feminine propriety. But the traits they represent – aspiration, knowledge, strength, desire – are not hideous. In men’s hands, they have always been heroic.
The monsters of myth have been stationed at those borders in order to keep us out; they are intended as warnings about what happens when women aspire beyond what we’re allowed. … They mark areas on a map: Do not enter. Here be monsters.
But if stepping outside the boundaries makes you monstrous, that means monsters are no longer bound. What happens if we charge through the gates and find that living on the other side – in all our Too Muchness, oversized and overweening and overcomplicated as we are – means living fully for the first time? Then the monster story stops being a warning sign, and starts to be a guide.
At the end of “Just Use Your Thinking Pump!”, a lovely essay that discusses the evolution (and perhaps undue elevation) of a particular set of practices now known as the scientific method, Jessica Riskin writes:
Covid-19 has presented the world with a couple of powerful ultimatums that are also strikingly relevant to our subject here. The virus has said, essentially, Halt your economies, reconnect science to a whole understanding of yourself and the world, or die.
With much economic activity slowed or stopped to save lives, let us hope governments find means to sustain their people through the crisis.
Meanwhile, with the din of “innovation” partially silenced, perhaps we can also use the time to think our way past science’s branding, to see science once again as integral to a whole, evolving understanding of ourselves and the world.
True, the world has presented us with an ultimatum. We must halt our economies, reconnect science to a whole understanding of ourselves and our world, or die.
Riskin is a professor at Stanford. Her skies are blackened with soot. In the words of Greta Thunberg, “Our house is on fire.”
For many years, we’ve measured the success of our economy in terms of growth. The idea that we can maintain perpetual growth is a delusion. It’s simple mathematics. If the amount of stuff we manufacture – telephones, televisions, air conditioners – rises by 3% each and every year, we’ll eventually reach stratospheric, absurd levels.
In the game “Universal Paperclips,” you’re put in control of a capitalist system that seeks perpetual growth. If you succeed, you’ll make a lot of paperclips! And you will destroy the planet.
Here in the real world, our reckless pursuit of growth has (as yet) wrought less harm, but we’ve driven many species to extinction, destroyed ancient forests, and are teetering at the precipice of cataclysmic climate change. All while producing rampant inequality with its attendant abundance of human misery.
We must reconnect science to a whole understanding of ourselves and the world, or die.
We are in danger. But Covid-19 isn’t the major threat we’re facing.
I consider myself to be more cautious than average – I would never ride a bicycle without a helmet – and I’m especially cautious as regards global pandemic. Antibiotic resistance is about to be a horrific problem for us. Zoogenic diseases like Covid-19 will become much more common due to climate change and increased human population.
I’m flabbergasted that these impending calamities haven’t caused more people to choose to be vegan. It seems trivial – it’s just food – but a vegan diet is one of our best hopes for staving off antibiotic resistant plagues.
A vegan diet would have prevented Covid-19. Not that eating plants will somehow turbocharge your immune system – it won’t – but this pandemic originated from a meat market.
And a vegan diet will mitigate your contribution to climate change, which has the potential to cause the full extinction of the human race.
Make our planet uninhabitable? We all die. Make our planet even a little less habitable, which leads to violent unrest, culminating in warring nations that decide to use nukes? Yup, that’s another situation where we all die.
By way of contrast, if we had made no changes in our lives during the Covid-19 pandemic – no shutdown, no masks, no social distancing, no PCR tests, no contact tracing, no quarantines – 99.8% of our population would have survived.
Indeed, we often discuss the Covid-19 crisis in a very imprecise way. We say that Covid-19 is causing disruptions to learning, that it’s causing domestic violence or evictions. On the front page of Sunday’s New York Times business section, the headline reads, “The Other Way that Covid Kills: Hunger.”
Covid-19 is a serious disease. We need to do our best to avoid exposing high-risk people to this virus, and we should feel ashamed that we didn’t prioritize the development of coronavirus vaccines years ago.
But there’s a clear distinction between the harms caused by Covid-19 (hallucinogenic fevers, cardiac inflammation, lungs filling up with liquid until a person drowns, death) and the harms caused by our response to Covid-19 (domestic violence, educational disruption, starvation, reduced vaccination, delayed hospital visits, death).
Indeed, if the harms caused by our response to Covid-19 are worse than the harms caused by Covid-19 itself, we’re doing the wrong thing.
In that New York Timesbusiness article, Satbir Singh Jatain, a third-generation farmer in northern India, is quoted: “The lockdowns have destroyed farmers. Now, we have no money to buy seeds or pay for fuel. …. soon they will come for my land. There is nothing left for us.”
Covid-19 is awful. It’s a nasty disease. I’m fairly confident that I contracted it in February (before PCR tests were available in the United States), and my spouse says it’s the sickest she’s ever seen me.
Yes, I’d done something foolish – I was feeling a little ill but still ran a kilometer repeat workout with the high school varsity track team that I volunteer with. High intensity workouts are known to cause temporary immunosuppression, usually lasting from 3 to 72 hours.
My whole family got sick, but I fared far worse than the others.
It was horrible. I could barely breathe. Having been through that, it’s easy to understand how Covid-19 could kill so many people. I wouldn’t wish that experience on anyone.
And I have very low risk. I don’t smoke. I don’t have diabetes. I’m thirty-seven.
I wish it were possible to protect people from this.
Obviously, we should have quarantined all international travelers beginning in December 2019. Actually, ten days probably would have been enough. We needed to diecitine all international travelers.
By February, we had probably allowed Covid-19 to spread too much to stop it.
By February, there were probably enough cases that there will always be a reservoir of this virus among the human species. 80% of people with Covid-19 feel totally fine and don’t realize they might be spreading it. By talking and breathing, they put viral particles into the air.
By the end of March, we were much, much too late. If you look at the numbers from New York City, it’s pretty clear that the preventative measures, once enacted, did little. Given that the case fatality rate is around 0.4%, there were probably about 6 million cases in New York City – most of the population.
Yes, it’s possible that New York City had a somewhat higher case fatality rate. The case fatality rate depends on population demographics and standard of care – the state of New York had an idiotic policy of shunting Covid-19 patients into nursing homes, while banning nursing homes from using Covid-19 PCR tests for these patients, and many New York doctors were prescribing hydroxychloroquine during these months, which increases mortality – but even if the case fatality rate in New York City was as high as 0.6%, a majority of residents have already cleared the virus by now.
The belated public health measures probably didn’t help. And these health measures have caused harm – kids’ schooling was disrupted. Wealthy people got to work from home; poor people lost their jobs. Or were deemed “essential” and had to work anyway, which is why the toll of Covid-19 has been so heavily concentrated among poor communities.
The pandemic won’t end until about half of all people have immunity, but a shutdown in which rich people get to isolate themselves while poor people go to work is a pretty shitty way to select which half of the population bears the burden of disease.
I am very liberal. And it’s painful to see that “my” political party has been advocating for policies that hurt poor people and children during the Covid-19 pandemic.
Because we did not act soon enough, Covid-19 won’t end until an appreciable portion of the population has immunity – at the same time.
As predicted, immunity to Covid-19 lasts for a few months. Because our public health measures have caused the pandemic to last longer than individual immunity, there will be more infections than if we’d done nothing.
The shutdowns, in addition to causing harm on their own, will increase the total death toll of Covid-19.
Unless – yes, there is a small glimmer of hope here – unless we soon have a safe, effective vaccine that most people choose to get.
Yes, there are clear positive externalities to vaccination, but I think this sounds like a terrible idea. Ethically, it’s grim – the Covid-19 vaccines being tested now are a novel type, so they’re inherently more risky than other vaccines. By paying people to get vaccinated, we shift this burden of uncertainty onto poor communities.
We already do this, of course. Drug trials use paid “volunteers.” Especially phase 1 trials – in which drugs are given to people with no chance of medical benefit, only to see how severe the side effects are – the only enrollees are people so poor that the piddling amounts of money offered seem reasonable in exchange for scarfing an unknown, possibly poisonous medication.
Just because we already do an awful thing doesn’t mean we should make the problem worse.
And, as a practical matter, paying people to do the right thing often backfires.
To illustrate, consider the recent introduction, in many Indian states, of schemes of cash incentives to curb sex-selective abortion. The schemes typically involve cash rewards for the registered birth of a girl child, and further rewards if the girl is vaccinated, sent to school, and so on, as she gets older.
These schemes can undoubtedly tilt economic incentives in favor of girl children. But a cash reward for the birth of a girl could also reinforce people’s tendency to think about family planning in economic terms, and also their perception, in the economic calculus of family planning, that girls are a burden (for which cash rewards are supposed to compensate).
Further, cash rewards are likely to affect people’s non-economic motives. For instance, they could reduce the social stigma attached to sex-selective abortion, by making it look like some sort of ‘fair deal’ — no girl, no cash.
What happens if it takes a few years before there are sufficient doses of an effective vaccine that people trust enough to actually get?
Well, by then the pandemic will have run its course anyway. Masks reduce viral transmission, but they don’t cut transmission to zero. Even in places where everyone wears masks, Covid-19 is spreading, just slower.
I’ve been wearing one – I always liked the Mortal Kombat aesthetic. But I’ve been wearing one with the unfortunate knowledge that masks, by prolonging the pandemic, are increasing the death toll of Covid-19. Which is crummy. I’ve chosen to behave in a way that makes people feel better, even though the science doesn’t support it.
We, as a people, are in an awful situation right now. Many of us are confronting the risk of death in ways that we have not previously.
More than 37 percent of deaths in 1900 were caused by infectious diseases, but by 1955, this had declined to less than 5 percent and to only 2 percent by 2009.
Of course, this trend will still hold true in 2020. In the United States, there have been about 200,000 Covid-19 deaths so far, out of 2,000,000 deaths total this year. Even during this pandemic, less than 1% of deaths are caused by Covid-19.
And I’m afraid. Poverty is a major risk factor for death of all causes in this country. Low educational attainment is another risk factor.
My kids am lucky to live in a school district that has mostly re-opened. But many children are not so fortunate. If we shutter schools, we will cause many more deaths – not this year, but down the road – than we could possibly prevent from Covid-19.
Indeed, school closures, by prolonging the pandemic (allowing people to be infected twice and spread the infection further), will increase the death toll from Covid-19.
School closures wouldn’t just cause harm for no benefit. School closures would increase the harm caused by Covid-19 and by everything else.
Recently, a local science teacher sent me an essay written by a climate change skeptic.
Well, okay. I figured that I could skim the essay, look over the data, and briefly explain what the author’s errors were. After all, it’s really important to help teachers understand this topic, because they’re training our next generation of citizens.
And I thought to myself, how hard can this be? After all, I’m a scientist. I felt unconcerned that I’ve never read research papers about climate science before, and that it’s been years since I’ve worked through the sort of differential equations you need for even basic fluid mechanics calculations, and that I’ve never run any simulations on oceanic heat transfer or glacier melting.
Since then, I’ve read a fair bit about climate science. I’ll be honest: I didn’t go through the math. All I did was read the papers and look over the processed data.
This is lazy, I know. I’m sorry. But my kids are at home. At the moment, this is the best I’ve got.
Prominent climate change skeptic Richard Lindzen, an emeritus professor of meteorology, recently delivered a lecture to the Global Warming Policy Foundation. I wholeheartedly agreed with Lindzen when he stressed that the science behind climate change is really, really complicated.
Former senator and Secretary of State John F. Kerry is typical when he stated, with reference to greenhouse warming, ‘I know sometimes I can remember from when I was in high school and college, some aspects of chemistry or physics can be tough. But this is not tough. This is simple. Kids at the earliest age can understand this.’
As you have seen, the greenhouse effect is not all that simple. Only remarkably brilliant kids would understand it. Given Kerry’s subsequent description of climate and its underlying physics, it was clear that he was not up to the task.
Climate science is tricky. In a moment, I’ll try to explain why it’s so tricky.
When people make predictions about what’s going to happen if the average global temperature rises by half a degree – or one degree, or two – their predictions are probably incorrect.
My assumption that I could skim through somebody’s essay and breezily explain away the errors was incredibly arrogant. I was a fool, I tell you! A fool!
But my arrogance pales in comparison to the hubris of climate change skeptics. Once I started learning about climate science, I realized how maddeningly difficult it is.
Lindzen, who should know better, has instead made brash claims:
So there you have it. An implausible conjecture backed by false evidence and repeated incessantly has become politically correct ‘knowledge,’ and is used to promote the overturn of industrial civilization. What we will be leaving our grandchildren is not a planet damaged by industrial progress, but a record of unfathomable silliness as well as a landscape degraded by rusting wind farms and decaying solar panel arrays.
There is at least one positive aspect to the present situation. None of the proposed policies will have much impact on greenhouse gases. Thus we will continue to benefit from the one thing that can be clearly attributed to elevated carbon dioxide: namely, its effective role as a plant fertilizer, and reducer of the drought vulnerability of plants.
Meanwhile, the IPCC is claiming that we need to prevent another 0.5ºC of warming, although the 1ºC that has occurred so far has been accompanied by the greatest increase in human welfare in history.
So. What aspects of climate science can we understand, and what’s too hard?
Let’s start with the easy stuff. Our planet gets energy from the sun. The sun is a giant ball of thermonuclear fire, spewing electromagnetic radiation. When these photons reach Earth, they’re relatively high energy – with wavelengths mostly in the visible spectrum – and they’re all traveling in the same direction.
What we do – “we” here referring to all the inhabitants of our planet, including the rocks and plants and other animals and us – is absorb a small number of well-organized, high-energy photons, and then release a larger number of ill-organized, low-energy photons. This is favorable according to the Second Law of Thermodynamics. We’re making chaos.
And here’s the greenhouse effect: if the high-energy photons from the sun can pass through our atmosphere, but then the low-energy photons that we release get absorbed, we (as a planet) will retain more of the sun’s energy. Our planet heats up.
And, in defense of former senator John Kerry, this is something that a kid can understand. My children are four and six, and this summer we’re going to build a solar oven out of a pane of glass and a cardboard box. (After all, we need stuff to do while all the camps are closed.)
If we fill our air with more carbon dioxide, which lets the sun’s high-energy photons in but then won’t let our low-energy photons out, the planet should heat up, right? What’s the hard part?
Well, the problem – the reason why climate science is too difficult for humans to predict, even with the most powerful computers at our command – is that there are many feedback loops involved.
Some of these are “negative feedback loops” – although atmospheric carbon dioxide causes us to absorb more energy from the sun, various mechanisms can buffer us from a rise in temperature. For example, warm air can hold more water vapor, leading to more cloud formation, which will reflect more sunlight back into space. If the sun’s high-energy photons can’t reach us, the warming stops.
And some are “positive feedback loops” – as we absorb extra energy from the sun, which causes the planet to heat up a little, various mechanisms can cause us to absorb even more energy in the future, and then the planet will heat up a lot. This may be what happened on Venus. The planet Venus may have been habitable, a long long time ago, but then runaway climate change led to the formation of a thick layer of smog, and now it’s broiling, with sulfuric acid drizzling from the sky.
On Earth, an example of a positive feedback loop would be the melting of polar ice caps. As polar ice melts, it reflects less light, so our planet absorbs more of the sun’s energy. Heat made the ice melt in the first place, but then, once the ice has melted, we heat up even more.
And it turns out that there are a huge number of different positive and negative feedback loops. After all, our planet is really big!
For instance, the essay I was sent included graphs of ice core data suggesting that, in the ancient past, changes in average global temperatures may have preceded changes in the concentration of atmospheric carbon dioxide.
But this is just another feedback loop. In the past, there was no mechanism for carbon dioxide to pour into our atmosphere before temperatures rose – dinosaurs didn’t invent internal combustion engines. This is the first time on Earth when carbon dioxide levels could rise before temperatures, and we don’t know yet what the effect will be.
Extra carbon dioxide will probably cause an increase in temperature, but a planet’s climate is really complicated. We have huge quantities of poorly mixed water (otherwise known as oceans). Our topography is jagged, interspersed with valleys and mountains. There are huge forests (only some of which are on fire). The air is turbulent.
We might find that temperatures are buffered more than we thought. The ocean might act like a giant heat sink.
Or then again, the ocean might warm up, accelerate polar ice loss by lapping at the undersides of glaciers, and magnify the changes.
The mathematics underlying fluid mechanics and heat transfer within an enormous, inhomogeneous system are so complex that it’s almost impossible to say. Nobody knows how much detail you’d need to put into a simulation to get accurate results – all we know for sure is that we can’t simulate the world with as much detail as actually exists. All our models are approximations. Some of them contradict each other.
With my admittedly limited understanding, I don’t think anybody knows enough to assert with confidence whether our climate will exhibit either buffered or switch-like behavior. Maybe we can muck about without hurting much. Or we might bring about our own doom with a tiny mistake.
Our planet’s climate is so complex that you could make a similar argument – we really don’t know whether we’re going to be buffered from future changes, or whether we’re at the precipice of doom – no matter what evidence we obtain.
Maybe sea levels start rising – well, perhaps that will somehow reduce the further heating of our planet. Maybe we get more horrible tropical storms – well, perhaps they’re linked to a greater density of sunlight-reflecting clouds.
Maybe things seem to be changing fast for a little while, but then we enter another stable state.
Or, insidiously, maybe it will seem like we’re in a well-buffered system – pumping large amounts of carbon dioxide and methane into the atmosphere without seeing much harm – until, suddenly, we tip over the edge. We often see that sort of behavior from positive feedback loops. Nothing seems to happen, for a while, then everything changes at once. That’s how cooperative binding of oxygen to hemoglobin works in your body.
Another problem is that climate change will probably happen on a very different rhythm from our lives. Weather happens on timescales that we can understand. A decade of droughts. Two years of tropical storms. A few hard winters, or hot summers. But climate happens over hundreds or thousands of years. Most of the time, it changes more slowly than we’d notice.
A two degree shift in average global temperatures, spread out over a few decades? That’s bad, but it’s boring. Which was the main focus of Jonathan Safran Foer’s We Are the Weather.
History not only makes a good story in retrospect; good stories become history. With regard to the fate of our planet – which is also the fate of our species – that is a profound problem. As the marine biologist and filmmaker Randy Olson put it, “Climate is quite possibly the most boring subject the science world has ever had to present to the public.”
Climate science doesn’t fit our culture. Especially not now, when the pressures of surveillance capitalism have forced even the New York Times to run like an advertising company. They earn more from news that gets clicks. Stories need to be sensational. Yes, they run stories about climate change. For these, the polar bears need to be dying, now, and there needs to be an evil villain like Exon lurking in the shadows.
Nobody wants to click on a story explaining that we, collectively, have made and are making a whole lot of small shabby decisions that will cause grizzly bears and polar bears to re-mix and de-speciate.
I got bored even typing that sentence.
Life is incredibly robust.
Our planet has swung through many extremes of temperature. At times, it’s been much hotter than it is now. At times, it was much colder. And life has marched on.
The human species is much less robust than life itself, though. Our kind has flourished for only a brief twinkling of time, during which our climate has been quite stable and mild. A small change could drive us to extinction. An even smaller change could cause our nations to collapse.
Disrupt our food supply – which could happen with just a few years of bad weather, let alone climate change – and there will be war.
So. I tried to learn about climate change, focusing on the work of skeptics. And in the end, I partly agreed with the skeptics:
I agree that climate science is too complicated for anyone to understand.
I appreciate that people are trying. I had fun learning about ice cores, atmospheric modeling, energy absorption, and the like. Well, sometimes I was having fun. I also gave myself several headaches along the way. But also, my kids were being wild. They’ve been home from school for three months now! I was probably on the precipice of headaches before I even began.
Here’s where I disagree with the skeptics, though: given that climate science is too complicated for us to understand – and given that we know that small changes in average temperature can make the world a much worse place to live – why would be blithely continue to perturb our climate in an unprecedented way?
Maybe things will be fine. Yay buffers! Or maybe we’ll reduce the carrying capacity of the planet Earth from a few billion humans to a few million, dooming most of our kind.
I know, I know – eventually our universe will dwindle into heat death, so our species is terminal anyway. We will go extinct. It’s guaranteed.
I still think it would be neat if our great-great-grandchilden were out there among the stars. At least for a little while.
Or even, if they stay here on Earth, it’s nice to imagine them living on a comfortable planet with lots of beautiful trees, and interesting animals to see.
Also, I’m biased.
After all, what are the things that you’re supposed to do if you want to reduce your carbon emissions?
Eat fewer animal products. Live in a smaller home. Drive less. Fly less. Buy less stuff.
Those are all things that I’d recommend to most Americans, for ethical and philosophical reasons, even if we weren’t concerned about climate change. So for me, personally, I don’t need to see much proof that we’ll ruin our climate unless we do these things. I think we should be doing them anyway.
Instead, I think the burden of proof should fall to the people hawking Big Macs. I’d want them to show that a world full of CAFO-raised cows won’t cause climate change, won’t propagate antibiotic resistant bacteria, won’t condemn billions of conscious beings to a torturous existence.
Midway through dinner, I thought I heard a strange sound. A faint bleating, maybe, that seemed to be coming from our backyard. Many musicians studying at the Jacobs School live in the apartment complex behind our house – we can often hear them practicing – but this didn’t sound like a conventional instrument.
I stood up, walked over to the window, and opened it, looking around our yard. It’s currently grackle mating season – watching a male grackle inflate his plumage to double his size is pretty incredible – and they make a variety of noises. So I suspected an ardent bird. I lingered there a moment, looking and listening, trying to determine where the sound had come from.
Those few seconds were too long.
I heard it again, and, with the window open, recognized the distress cry of a young rabbit.
I pulled off my socks, ran outside. Sprinted around our house to the small fenced enclosure where we have our air conditioning unit.
A large rabbit fled from the HVAC enclosure when it saw me. It bolted across the yard and slipped through the back fence.
Yes. Our yard has a lot of fences. We have dogs. The back fence keeps them inside the yard. The fence around the HVAC unit keeps our dogs from crashing into the various wires and tubing and ripping them from the wall (which our younger dog did last year, necessitating expensive repairs).
The distress call had stopped, but now I knew where to look. And there, sprawled on the mulch, was a juvenile rabbit, about as big as my hand. His fur had been ripped from his face, leaving his nose raw and bleeding; he was also bleeding from gaping wounds down his back, and his hind legs were broken. (I’m assuming gender here because I think that’s what triggered the attack – probably a territorial adult male felt that this juvenile was impinging on his territory.)
The mutilated juvenile sat watching me for a moment, then tried to hop away. He couldn’t. His legs kicked back slowly and he toppled.
Prostrate on his side, the wounds looked even worse. He was breathing heavily, watching me.
My children, still inside the house, called through the window to ask what was happening. I shook my head.
“There’s a baby rabbit, and he’s very, very hurt. He’s going to die.”
The kids wanted to come see. I didn’t really want them to – they are only four and six years old – but we all have to learn about death. Our elder child visited her grandfather in hospice while he was dying after a stroke, and she understands that her grandmother died after somebody hurt her. Our younger child is at an age where many of the stories she tells involve death, but I’m not sure she understands the permanence yet.
And the thing I really didn’t want to talk about – but would have to, for them to understand – is the brutality of territorial violence. I hadn’t known that it was so horrific in rabbits. This baby bunny had been murdered by an irate elder.
And the violence that we humans use to claim and protect territory is one of the worst aspects of our species. We are a brilliantly inventive species. Many – perhaps most – of our inventions sprang from the desire to make better weapons.
The world was here before us, but we pound sticks into the ground and say “This part of the world is mine.”
We’re far too fond of building walls.
The kids joined me outside. My spouse came out; as soon as she saw the poor rabbit, she cried. I tried, as gently and non-pedantically as I was able, to explain what had happened.
My younger child clasped her hands in front of her chin. “I’m sad the baby bunny is going to die.”
The rabbit’s breathing was clearly labored. I wonder how well he understood that this was the end.
“Yeah,” I said. “I’m sad, too.”
The sun was setting, and the air was starting to grow chilly. My spouse went back inside and cut up one of my old socks (I typically wear socks until they disintegrate, and my spouse thinks that any sock missing both the heel and toes is fair game to destroy, so we always have spare fabric on hand) to make a small blanket.
The dying rabbit probably felt scared – I’d asked the kids to keep a respectful distance, but we humans are quite large. Still, I tried to make myself as small as possible as I reached out to cover the rabbit’s torso with the blanket. I left my hand there, gently resting over his chest, for warmth. I could feel his panting breaths rise and fall beneath my palm.
I quietly offered my apologies and said a prayer. The rabbit watched me. I tried to smile with no teeth. I stayed crouching, immobile, until the rabbit’s breathing stopped five minutes later.
Then I went inside and finished eating dinner.
At times, being vegan is a comfort. All of us, in living, impose harms upon the world – that’s the unfortunate nature of existence. To grow food crops, we till the soil. Spray pesticides. And kill all those plants.
Our lives matter, too. If we don’t take care of ourselves, and strive to enjoy our time alive – if we don’t place value on our own lives – then how could we value others?
Still, my family tries to minimize the harm we wreck by being here. We live well, but try to be cognizant of the costs.
I was glad that the meal I returned to was made from only plants.
After I finished eating, I went and sat on our front porch with my children. We spread a blanket over our laps. We watched birds flit between the trees. A chipmunk dashed across the lawn. Two squirrels chased each other through a neighbors yard.
Our elder child clutched me tightly. I hugged her back. We sat silently. I didn’t know what to say.
Then it was time for the kids to go to bed.
It was my spouse’s turn to read the bedtime stories that night, and our dogs wanted to go outside, so I took them to the back yard.
I don’t think our dogs would hurt a rabbit – when my father-in-law died, the dwarf rabbit he’d purchased as a love token for his twenty-year-old ladyfriend came to live with us (they’d broken up a few days before his stroke, which is why she didn’t want to adopt the rabbit), and when our dogs dug up a rabbit’s nest two years ago, they gently carried a newborn bunny around the yard (we returned it to the nest and it survived until it was old enough to hop away).
I didn’t want for the dogs to carry the dead rabbit around our yard, though. Or hide it somewhere for the kids to find.
So I walked over to the HVAC unit, ready to explain to the dogs not to bother it. But the rabbit was gone. The sock blanket was still there, but no corpse.
We don’t live in a particularly rural area – we’re in Bloomington, about half a mile south of the Indiana University campus. Our backyard is shared with a sixty-unit apartment complex. And yet. Even here, the natural world is bustling enough that a dead thing can disappear within twenty minutes. I’ve seen hawks, vultures, crows, raccoons, possums, skunks. Many deer, and a groundhog, although they wouldn’t eat a rabbit. One semi-feral cat. I’ve seen foxes down the street from us, in fields a half mile away, but never in our yard.
And, it’s strange. The dead rabbit lay in our yard for less than twenty minutes. If we had been listening to music over dinner – which we often do – I wouldn’t have heard his cries through the glass windowpane.
Scientists often pride ourselves on our powers of observations. But noticing, this time, only made me sad. If I hadn’t heard that faint sound, I never would have realized that anything untoward had happened in our yard. And I could have remained blissfully ignorant of the ruthless violence that rabbits apparently inflict upon young children.
The natural world is not a peaceful place.
Still. I would rather know. Understanding the pervasive violence that surrounds us helps me to remember how important it is – since we have a choice – to choose to do better.
The choices we’re making might cause everyone to die.
kind of sad. I like being alive, and I
like the thought that other humans might be alive even after I am gone.
Some people – the original Millennials, for instance – prefer to imagine that the world would end when their world ends. But for those of us who feel that helping others adds to the meaning of our lives, it’s more satisfying to imagine humanity’s continued existence. Each good deed is like a wave, rippling outward, causing people to be a little kinder to others in turn.
These waves of kindness can’t last forever – our universe began with a finite quantity of order, which we use up in order to live – but they could persist for a very long time. Humans could have many billions of years with which to colonize the stars.
Unless we go extinct sooner. Which we might. We’re destabilizing the climate of the only habitable planet we know.
Venus used to be habitable. We humans could’ve flown there and set up a colony. But a blip of excess greenhouse gas triggered runaway climate change. Now Venus has no liquid water. Instead, the planet is covered in thick smog. Sulfuric acid rains from the sky.

There are things you can do to help. In We Are the Weather, Jonathan Safran Foer lists the (abundant!) evidence that animal agriculture is the leading cause of climate change.

driving, do it! Every effort you make to
waste less energy is worthwhile!
But it helps to take stock of the numbers. If everyone with a conventional automobile could suddenly exchange it for a hybrid vehicle, we’d still be emitting 96% as much greenhouse gas. If everyone decided to eliminate animal products from their diet, we’d be emitting 50% as much.

Deciding to eat plant-based foods would.
it’s hard to make this switch.
Not least because the peril we’ve placed ourselves in doesn’t feel
compelling. It’s like the difference
between venus flytraps and pitcher plants.
With a venus flytrap, you can see the exact moment that a bug is
doomed. Those spikey mandibles close and
that’s the end! When a bug lands on a
pitcher plant, though, its fate is sealed well before the moment when it
finally topples into the digestive water.
The lip of a pitcher plant is sloped and slippery; the actual boundary
between life and death is unnoticeable.
climate change will be exacerbated by so many feedback loops, by the time we
see the precipice it’ll be too late.
In Foer’s words,
The chief threat to human life – the overlapping emergencies of ever-stronger superstorms and rising seas, more severe droughts and declining water supplies, increasingly large ocean dead zones, massive noxious-insect outbreaks, and the daily disappearance of forests and species – is, for most people, not a good story.
planetary crisis matters to us at all, it has the quality of a war being fought
over there. We are aware of the
existential stakes and the urgency, but even when we know that a war for our
survival is raging, we don’t feel immersed in it. That distance between awareness and feeling
can make it very difficult for even thoughtful and politically engaged people –
people who want to act – to act.
not only makes a good story in retrospect; good stories become
history. With regard to the fate of our
planet – which is also the fate of our species – that is a profound
problem. As the marine biologist and
filmmaker Randy Olson put it, “Climate is quite possibly the most boring
subject the science world has ever had to present to the public.”
that Foer tries to wring empathy from this dull story. He writes about his personal struggles to be
good. If it were necessary to blow hot
air from a hairdryer into a small child’s face each time we bought a
cheeseburger, few people would buy them.
But it’s more difficult to restrain ourselves when we instead know
vaguely – rationally, unemotionally – that each cheeseburger we buy will
exacerbate the hot air – and floods, and droughts, and malaria – that children
will one day have to bear.

understand it, but we can’t feel it.
that’s the message of Foer’s book. How
can we – collaboratively – create a world in which it’s easy to do the right
thing? How can we make cheeseburgers feel
An intellectual understanding – cheeseburgers requires farms with cows, cows emit methane, cows take space, farmers destroy forests to make space, cheeseburgers cause climate change – isn’t enough to create that feeling. Climate change is too dull a story.
worse, climate change isn’t even the most boring story to tell about our
extinction. In We Are the Weather
– an entire book in which Foer castigates himself for contributing to harms
that will befall his descendants some 100 to 200 years in the future (because
that’s when climate change will get really bad) – Foer doesn’t even
mention that he’s also causing harms that will befall his descendants 30 to 60
years in the future.

even more dull.

Most farmed animals are constantly given low doses of antibiotics. As it happens, this is exactly the protocol you’d use for a directed evolution experiment if you were trying to make antibiotic-resistant bacteria.
There’s an old story about a king, Mithridates, whose father was assassinated with poison. Mithridates trained his body with exposure to low doses of poison so that he would be able to survive higher doses.

animal agriculture – any of those dozen infections could have killed my kids.
You should watch the New York Times video about antibiotic resistance. By 2050, it’s likely that more people will die from antibiotic resistant bacterial infections than from cancer.
Huge quantities of money are being spent to develop new anti-cancer drugs – new ways for elderly people to stave off time. Meanwhile, it’s not just that we spend so little developing antibiotics. We are actively making these drugs worse.
resistance isn’t a compelling story, though.
To feel a connection between a cheeseburger and your someday
grandkid dying in bed, feverish and septic, you’d have to understand the
biochemistry of lateral gene transfer, DNA replication, mutation, drug
metabolism. You’d need to be able to see
in your mind’s eye the conditions that farmed animals are raised in.

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.

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

Amazon rain forest. In retrospect, I’m

arrangement was supposedly akin to a rental or purchase of those trees.
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.

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.
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.

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.

and cheeses are responsible for somewhere between 20% and 50% of all
(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.)
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.

Every living thing needs
energy. But our world is finite. Energy has to come from somewhere.
Luckily, there’s a lot of potential energy out there in the universe. For instance, mass can be converted into energy. Our sun showers us with energy drawn from the cascade of nuclear explosions that transpire in its core. A tiny difference in mass between merging hydrogen atoms and the resultant helium atom allows our sun to shine.
Our sun radiates about 10^26 joules per second (which is 100,000 times more than the combined yearly energy usage from everyone on Earth), but only a fraction of that reaches our planet. Photons radiate outward from our sun in all directions, so our planet intercepts only a small sliver of the beam. Everything living here is fueled by those photons.
When living things use the sun’s energy, we create order – a tree converts disordered air into rigid trunk, a mouse converts a pile of seeds into more mouse, a human might convert mud and straw into a house. As we create order, we give off heat. Warming the air, we radiate infrared photons. That’s what night vision goggles are designed to see. The net effect is that the Earth absorbs high-energy photons that were traveling in a straight beam outward from the sun … and we convert those photons into a larger number of low-energy photons that fly off every which way.
We the living are chaos machines. We make the universe messier. Indeed, that’s the only way anything can live. According to the Second Law of Thermodynamics, the only processes that are sufficiently probable so as to occur are those that make the world more random.
We’re lucky that the universe started out as such a bland, orderly place – otherwise we might not even be able to tell “before” from “later,” let alone extract enough energy to live.
The earliest living things took energy from the sun indirectly – they used heat, and so they were fueled by each photon’s delivery of warmth to the Earth. (Please allow me this little hedge – although it’s true that the earliest life was fueled only by warmth, that warmth might not have come from the sun. Even today, some thermophilic bacteria live in deep sea vents and bask in the energy that leaks from our Earth’s molten core. The earliest life might have lived in similar nooks far from the surface of the Earth. But early life that resided near the surface of the seas seems more likely. Complicated chemical reactions were necessary to form molecules like RNA. Nucleic acids were probably first found in shallow, murky pools pulsed with lightning or ultraviolet radiation.)
Over time, life changed. Organisms create copies of themselves through chemical processes that have imperfect fidelity, after all. Each copy is slightly different than the original. Most differences make an organism worse than its forebears, but, sometimes, through sheer chance, an organism might be better at surviving or at creating new copies of itself.
When that happens, the new
version will become more common.
Over many, many generations, this process can make organisms very different from their forebears. When a genome is copied prior to cell division, sometimes the polymerase will slip up and duplicate a stretch of code. These duplication events are incredibly important for evolution – usually, the instructions for proteins can’t drift too far because any change might eliminate essential functions for that cell. If there’s a second copy, though, the duplicate can mutate and eventually gain some new function.
About two billion years ago, some organisms developed a rudimentary form of photosynthesis. They could turn sunlight into self! The energy from our sun’s photons was used to combine carbon dioxide and water into sugar. And sugar can be used to store energy, and to build new types of structures.
Photosynthesis also releases oxygen as a biproduct. From the perspective of the organisms living then, photosynthesis poisoned the entire atmosphere – a sudden rise in our atmosphere’s oxygen concentration caused many species to go extinct. But we humans never could have come about without all that oxygen.
Perhaps that’s a small consolation, given that major corporations are currently poisoning our atmosphere with carbon dioxide. Huge numbers of species might go extinct – including, possibly, ourselves – but something else would have a chance to live here after we have passed.
In addition to poisoning the atmosphere, photosynthesis introduced a new form of competition. Warmth spreads diffusely – on the early Earth, it was often sheer chance whether one organism would have an advantage over any other. If you can photosynthesize, though, you want to be the highest organism around. If you’re closer to the sun, you get the first chance to nab incoming photons.
That’s the evolutionary pressure that induced plants to evolve. Plants combined sugars into rigid structures so that they could grow upwards. Height helps when your main goal in life is to snatch sunlight.
Nothing can live without
curtailing the chances of other living things.
Whenever a plant absorbs a photon, it reduces the energy available for
other plants growing below.
Plants created the soil by
trapping dirt and dust, and soil lets them store water for later use. But there is only so much desalinated
water. Roots reach outward: “I drink your
milkshake!”, each could exclaim.
For a heterotroph, the
brutality of our world is even more clear.
Our kind – including amoebas, fungi, and all animals – can only survive
by eating others. We are carbon
recyclers. Sugar and protein
refurbishers. We take the molecular
machines made by photosynthesizing organisms … chop them apart … and use the
pieces to create ourselves.
Some heterotrophs are
saprophages – eaters of the dead. But
most survive only by destroying the lives of others.
For the earliest heterotrophs, to eat was to kill. But, why worry? Why, after all, is life special? Each photosynthesizing organism was already churning through our universe’s finite quantity of order in its attempt to grow. They took in material from their environment and rearranged it. So did the heterotrophs – they ingested and rearranged. Like all living things, they consumed order and excreted chaos.
The heterotrophs were
extinguishing life, but life is just a pattern that repeats itself. A living thing is a metabolic machine that
self-copies. From a thermodynamic
perspective, only the energetics of the process distinguish life from a
crystal. Both are patterns that grow,
but when a crystal grows, it makes matter more stable than its environment –
life makes matter less stable as it’s incorporated into the pattern.
Your ability to read this
essay is a legacy of the heterotrophs’ more violent descendants. The earliest multicellular heterotrophs were
filter feeders – they passively consumed whatever came near.
But then, between 500 and 600 million years ago, animals began to hunt and kill. They would actively seek life to extinguish. To do this, they needed to think – neurons first arose among these hunters.
Not coincidentally, this is also the time that animals first developed hard shells, sharp spines, armored plates – defenses to stop others from eating them.
The rigid molecules that allow plants to grow tall, like cellulose, are hard to digest. So the earliest hunters probably began by killing other animals.
With every meal, you join
the long legacy of animals that survived only by extinguishing the lives of
others. With every thought, you
draw upon the legacy of our forebear’s ruthless hunt.
Even if you’re vegan, your meals kill. Like us, plants have goals. It’s a matter of controversy whether they can perceive – perhaps they don’t know that they have goals – but plants will constantly strive to grow, to collect sunlight and water while they can, and many will actively resist being eaten.
But it makes no sense to value the world if you don’t value yourself. Maybe you feel sad that you can’t photosynthesize … maybe you’d search out a patch of barren, rocky ground so that you’d absorb only photons that would otherwise be “wasted” … but, in this lifetime, you have to eat. Otherwise you’d die. And I personally think that any moral philosophy that advocates suicide is untenable. That’s a major flaw with utilitarianism – rigid devotion to the idea of maximizing happiness for all would suggest that you, as another organism that’s taking up space, constantly killing, and sapping our universe’s limited supply of order, simply shouldn’t be here.
At its illogical extreme, utilitarianism suggests that either you conquer the world (if you’re the best at feeling happy) or kill yourself (if you’re not).
We humans are descended from carnivores. Our ancestors were able to maintain such large brains only by cooking and eating meat. Our bodies lack an herbivore’s compliment of enzymes that would allow us to convert grass and leaves into the full compliment of proteins that we need.
And we owe the very existence of our brains to the hunts carried out by even more ancient ancestors. If they hadn’t killed, we couldn’t think.
Just because we were blessed by a legacy of violence, though, doesn’t mean we have to perpetuate that violence. We can benefit from past harms and resolve to harm less in the present and future.
Writing was first developed by professional scribes. Scientific progress was the province of wealthy artisans. None of the progress of our culture would have been possible if huge numbers of people weren’t oppressed – food that those people grew was taken from them and distributed by kings to a small number of privileged scribes, artisans, philosophers, and layabouts.
When humans lived as hunters and gatherers, their societies were generally equitable. People might die young from bacterial infections, dehydration, or starvation, but their lives were probably much better than the lives of the earliest farmers. After we discovered agriculture, our diets became less varied and our lives less interesting. Plus, it’s easier to oppress a land-bound farmer than a nomadic hunter. Stationary people paid tribute to self-appointed kings.
This misery befell the vast majority of our world’s population, and persisted for thousands of years. But the world we have now couldn’t have come about any other way. It’s horrific, but, for humans to reach our current technologies, we needed oppression. Food was taken from those who toiled and given to those who hadn’t.
Mostly those others
created nothing of value … but some of them made writing, and mathematics, and
Although the development
of writing required oppression, it’s wrong to oppress people now. It was wrong then, too … but we can’t go back
and fix things.
Although the origin of
your brain required violence, I likewise think we ought to minimize the
violence we enact today. We can’t help
all the animals who were hurt in the long journey that made our world the place
it is now. And we can’t stop killing –
there’s no other way for heterotrophs like us to live.
To be vegan, though, is to reckon with those costs. To feel a sense of wonder at all the world pays for us to be here. And, in gratitude, to refrain from asking that it pay more than we need.
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.
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.
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.
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.
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.
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.
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.
world has treated me pretty well.

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