Look Who’s Talking: It’s the Animals--and They’re Very Upset

Look Who’s Talking

It’s the animals, and they’re very upset

Leo Kim/THE BAFFLER MAGAZINE
November 18, 2024

DURING THE HEIGHT OF THE PANDEMIC, when life was reduced to our screens, a poodle named Bunny captivated the world by speaking. More accurately, she captivated us by pressing buttons on a DIY soundboard that played a range of preprogrammed words. At first, Bunny had simple requests: a walk here, a treat there. Over time, however, Bunny’s ideas appeared to become more complex. In one video, she faced a mirror and button-mashed the question, “What, Bunny?” Many found themselves asking the same thing. Some saw her as a circus act for the TikTok age, while others saw a creature attempting to genuinely express itself.

The Seal of Solomon was once said to have granted the Israelite king the ability to speak to animals. These days, we have less faith in scriptural abracadabra; yet in their stead, a new magic has emerged: technology. Since Bunny first said hello to the world, this magic has only grown in scale and complexity. Just a few years later and that soundboard already appears like a primitive relic of a distant past, gone the way of Solomon. Now it’s no longer low-tech buttons but sleek “artificial intelligence” — that newest and most powerful of our sacred technologies — that has captured our imagination and hopes of interspecies communication.

Having successfully translated English to French and French to Russian and Russian to Japanese, researchers are now interested in using neural networks to translate Whale to English, Chimpanzee to French. The proposal may sound like the stuff of fairy tales, but the idea has gained traction amid a hype-driven mediascape in which just about anything slapped with the AI label is considered of potentially epochal importance. Buzzy headlines have started to speculate how “Artificial Intelligence Could Finally Let Us Talk with Animals,” questioned “How First Contact With Whale Civilization Could Unfold,” and giddily anticipated the “AI Pet Translator Apps” to come. In the future, Bunny will be legion.

Lest one accuse this project of superfluity, its proponents have bestowed a certain moral urgency on the effort. Using technology to help us hear these creatures out and witness their plight, the thinking goes, will shake us from the murderous apathy that has plagued our relationship with the natural world. Though past attempts at appealing to the better angels of our nature haven’t exactly stopped the slaughter, these techno-solutionists assure us that AI will allow us to resolve this problem of miscommunication once and for all by letting us hear straight from the literal horse’s mouth. We won’t be able to brush off the desperate pleas of these creatures any longer because they’ll be begging for their lives in fluent English.

The notion that speaking with animals might deliver us to some deeper empathic attunement with the natural world is relatively new. For most of Western history, we assumed that animals simply didn’t have anything interesting to say. Two millennia ago, Aristotle insisted that logos — the capacity for reflection, reason, and language — separated man from the rest of the animal world. During the first throes of the Enlightenment, Descartes, who had constructed his entire worldview off of the singular certainty of the thinking mind, described nonhuman animals as thoughtless meat machines reacting impulsively to stimuli. Even at the end of the nineteenth century, mainstream anthropologists thought that humans might have arisen from a “revolution” in cognition that ruptured us from the mute animal world.

All that now separates us from enlightenment is a few more rounds of funding.

Only in the past century did we begin to earnestly explore the possibility that animals might suffer and hope and feel. The 1960s and 1970s in particular saw a surge of interest in animal cognition and communication. It was during this time that researchers taught chimps like Washoe sign language and worked to decode the complex signals of species like songbirds and dolphins. Even considering the more gruesome experiments carried out in this consciousness-expanding spirit (honorable mention goes to the researchers that killed an elephant by injecting it with 297 mg of LSD and the Navy project to enlist dolphins in the fight against godless communism), this period is generally remembered for countering our dismissive view of the animal kingdom. We started to see these creatures as more than mindless automata. When we learned that whales sing, for instance, we played their songs to galvanize public support against whaling.

Inspired by this history, contemporary techno-solutionists have figured that we might bring this arc of empathy to its zenith by tearing down the final barrier they see as separating us: language. There are now research initiatives looking to decode everything from elephant calls to the dancing movements of bees and melodies of birdsong, all inspired by this notion that piecing together the fragments of Babel and restoring communication between earth’s creatures will finally usher in an era of harmony. These tools will help “a society that is disconnected from nature to reconnect with it,” as one leading researcher told Wired. Or as the highly publicized Cetacean Translation Initiative, or Project CETI for short, put it, if the discovery that whales could sing helped ban whaling, then just “imagine what would happen if we could understand” them.

The sentiment has opened wallets. Project CETI has raised upwards of $33 million for their plan, which they lay out in three easy steps:

1. Achieve advancements and breakthroughs in interspecies communication.

2. Transform human understanding & connectivity.

3. Share our learnings with the world.

As the background of the team — composed largely of machine-learning researchers from both academia and for-profit companies like Google — makes clear, these “advances and breakthroughs” are expected to come from the domain of machine learning: an application of AI focused on developing systems that autonomously refine their performance over time. In its simplest terms, these technologies would map the structure of the whale-speak, plotting different linguistic units within a multidimensional matrix of relationships; then, by overlaying the complex “shape” of whale language to that of our own, researchers could translate between the two without the need of a mediating Rosetta Stone since overlapping points on these maps would indicate a corresponding definition. From there, the transformation of “human understanding and connectivity” would follow, obviously.

Similar enterprises have sprung up across the board, looking to get in on the action. Apps like MeowTalk and such organizations as Zoolingua have set their sights on our furry friends — using AI to mediate our relationships with our domesticated cats and dogs, respectively. Meanwhile more grandiose (and better funded) organizations like the Earth Species Project have projects underway to help decode the communication of crows and beluga whales, among others. “Like the telescope, these new tools will forever change our perspective,” they proclaim. Though one might reasonably question whether these “new tools” will actually resemble the telescope as much as the parade of pernicious platforms and technologies that Earth Species’ cofounders — which include a founding member of the platform formerly known as Twitter, the creator of the infinite scroll, and “an early member” of the Facebook team — have had a hand in developing in the past.

Regardless, these plans continue to gleam with the confidence of a syllogism. Having conceptually intertwined technological innovation with empathic transformation, all that now separates us from enlightenment is a few more rounds of funding. Yet the foundations underlying this dream of tech enabled eco-communion are dubious at best. In fact, subjected to even the mildest of scrutiny, it becomes clear that this salvific faith in technology betrays less a commitment to transforming ourselves for the better than it does a lazy desire to double down on the same traits that landed us in this mess: a persistent belief in the power of individual reason, an overreliance on techno-fixes, and a constant need to shape the world in our own image.

Given that this whole scheme relies on the transformative power of language, it’s surprising that the perils that surround this power are so often ignored — a consequence, perhaps, of the fact that these projects rarely employ more than a handful of actual linguists. Language is not the blindly unifying tool that these techno-delusionists characterize it as; it not only builds bridges but burns them down. My grandfather grew up learning Japanese because his native tongue, Korean, had been banned by the colonial government. It’s a familiar story for anyone who has suffered under imperialism, whether you’re Korean, Cherokee, Algerian, Irish, (the list goes on). Language contains and constructs worlds, serves as the vehicle through which culture disseminates and politics arise. To control language is to control the medium that conditions thought. No wonder that the forced imposition of language is a favorite tactic of empire.

These initiatives are little more than red herrings that, like most techno-fixes, puts the onus of change on individual self-betterment instead of systemic upheaval.

Seen in this light, the desire to translate nonhuman thought into human language is anything but innocuous. The philosopher of language Ludwig Wittgenstein once quipped that “if a lion could talk, we could not understand him.” This aphorism is a reminder that the umwelten of these animals — the phenomenal shape of their experience, the mental states that orient them toward the world — are so radically different from our own, the language we have crafted for our all too human lives cannot capture the full breadth of their existence. It’s one reason why, as a recent New Yorker article observed, many animal communications experts don’t expect “straightforward translations” to be forthcoming, since “animals live in perceptual worlds that are just too different.” Eco-theorists have built on this, arguing that an honest relationship with the nonhuman requires us to first acknowledge the fundamental differences that shape us. Only by cultivating an empathy that cuts across these divides might we move beyond the narcissism that has long polluted our relationship to the broader world.

Yet rather than help us appreciate this radical diversity and overcome our self-centeredness, AI translation aims to smooth everything out into easily legible conformity. This wouldn’t deliver us to real understanding as much as its false pretense — turning bats, lions, and whales into cheap caricatures robbed of complexity. Conveniently, this would also allow us to avoid the difficult task of teaching ourselves to see and listen to these animals in a way that respects all that’s unique about them. Why stretch our networks of care to these alien forms of existence when we can just reinforce the self-serving notion that life only matters to the extent that it is “like us?” Having confronted something wonderful and new, we’ve opted not to explore these vast unknowns — by crafting new concepts or modes of experience capable of capturing the unfamiliar — but have told them to speak English.

Despite these concerns, there will be those who continue to believe in the possibility of meaningful translation. For these techno-optimists’ sake, let’s assume that everything miraculously works out. Let’s assume that we’ll successfully extend our already bloated surveillance apparatuses into the oceans and forests to scrape enough data to feed these models — and that the shapes of these animal and human signaling systems will line up so perfectly that these creatures become our new English-speaking, all-American pen pals. Even in this best case scenario it’s still unclear what we would say to each other, much less what this would actually achieve.

After all, it’s not like we’re utterly incapable of understanding animals right now. The idea that we might use this line of communication to ask whales if shipping vessels have grown too loud or if they can feel the effects of climate change, as some have proposed, betrays an implausible naivete. Of course our boats are too loud; of course whales can feel the effects of climate change. Their suffering is no great mystery — just look at how they die, starving with bellies full of plastic. AI couldn’t do more to convey what is already so obvious to anyone willing to look. We’re not destroying the planet because we lack the right “facts of the matter” but because our devastating systems are fundamentally irrational, premised on paradoxical axioms like perpetual growth.

Not to say that versions of these tools don’t have useful local implementations. Author and researcher Karen Bakker, for instance, has observed how shipping lanes can respond to whale traffic by employing digital bioacoustics and predictive AI to identify the paths of these creatures and reroute ships accordingly. Yet absent is the sense that global winds of consumption blowing these ships across oceans (and straight into twenty thousand whales annually) will change from speaking to these animals. Though we might prevent a few hit-and-runs, a multimillion dollar equivalent of a school crossing guard is a far cry from the transformative panacea that this technology is being hyped up to be.

If these technologies do hold the appeal of total transformation, the nature of this transformation lies elsewhere. We sense it when, for example, considering the question of what we might say to these animals, the late biologist Roger Payne remarked that “sorry would be a good word.” Tellingly, it’s a sentiment frequently echoed in conversations about this research. In the end, we seem to desire purification through the sacrament of confession more than hearing what these creatures would say in order to actually act on it. We’ve convinced ourselves that saving these animals first requires us to save ourselves by assuaging our own guilt. In short, as we so often do, we’ve made it all about us.

These initiatives are little more than red herrings that, like most techno-fixes, puts the onus of change on individual self-betterment instead of systemic upheaval. Yet no amount of feel-good personal enlightenment will alter anything without first dismantling the economic and legal infrastructures desecrating the planet. The romantic role of whale song in banning whaling shouldn’t overshadow the mundane fact that overhunting and the invention of resource alternatives like kerosene and vegetable oils had already made whaling a far less profitable prospect by that point. Hearts may bleed, but until wallets do, few things tend to change.

Like the investor pitches of so many failed startups, the promise of AI animal communication sells us transcendence while delivering something that already exists wrapped up in silicon packaging — this time with the added irony that we’re being asked to funnel millions of dollars into a water-guzzlingemissions-pumping technology to save nature by teaching us basic empathy. If we continue to wait for the machine to equip us with the capacity to care, it’ll be too late. By the time we’ve figured out how to apologize to the whales, their songs will have long fallen silent.

Modern Zoos Are Not Worth the Moral Cost by Emma Marris for THE NEW YORK TIMES


Modern Zoos Are Not Worth the Moral Cost

  • GUEST ESSAY

After being captives of the pandemic for more than a year, we have begun experiencing the pleasures of simple outings: dining al fresco, shopping with a friend, taking a stroll through the zoo. As we snap a selfie by the sea lions for the first time in so long, it seems worth asking, after our collective ordeal, whether our pleasure in seeing wild animals up close is worth the price of their captivity.

Throughout history, men have accumulated large and fierce animals to advertise their might and prestige. Power-mad men from Henry III to Saddam Hussein’s son Uday to the drug kingpin Pablo Escobar to Charlemagne all tried to underscore their strength by keeping terrifying beasts captive. William Randolph Hearst created his own private zoo with lions, tigers, leopards and more at Hearst Castle. It is these boastful collections of animals, these autocratic menageries, from which the modern zoo, with its didactic plaques and $15 hot dogs, springs.

The forerunners of the modern zoo, open to the public and grounded in science, took shape in the 19th century. Public zoos sprang up across Europe, many modeled on the London Zoo in Regent’s Park. Ostensibly places for genteel amusement and edification, zoos expanded beyond big and fearsome animals to include reptile houses, aviaries and insectariums. Living collections were often presented in taxonomic order, with various species of the same family grouped together, for comparative study.

The first zoos housed animals behind metal bars in spartan cages. But relatively early in their evolution, a German exotic animal importer named Carl Hagenbeck changed the way wild animals were exhibited. In his Animal Park, which opened in 1907 in Hamburg, he designed cages that didn’t look like cages, using moats and artfully arranged rock walls to invisibly pen animals. By designing these enclosures so that many animals could be seen at once, without any bars or walls in the visitors’ lines of sight, he created an immersive panorama, in which the fact of captivity was supplanted by the illusion of being in nature.

Mr. Hagenbeck’s model was widely influential. Increasingly, animals were presented with the distasteful fact of their imprisonment visually elided. Zoos shifted just slightly from overt demonstrations of mastery over beasts to a narrative of benevolent protection of individual animals. From there, it was an easy leap to protecting animal species.

The “educational day out” model of zoos endured until the late 20th century, when zoos began actively rebranding themselves as serious contributors to conservation. Zoo animals, this new narrative went, function as backup populations for wild animals under threat, as well as “ambassadors” for their species, teaching humans and motivating them to care about wildlife. This conservation focus “must be a key component” for institutions that want to be accredited by the Association of Zoos and Aquariums, a nonprofit organization that sets standards and policies for facilities in the United States and 12 other countries.

This is the image of the zoo I grew up with: the unambiguously good civic institution that lovingly cared for animals both on its grounds and, somehow, vaguely, in their wild habitats. A few zoos are famous for their conservation work. Four of the zoos and the aquarium in New York City, for instance, are managed by the Wildlife Conservation Society, which is involved in conservation efforts around the world. But this is not the norm.

While researching my book on the ethics of human interactions with wild species, “Wild Souls,” I examined how, exactly, zoos contribute to the conservation of wild animals.

A changing climate, a changing world

Climate change around the world: In “Postcards From a World on Fire,” 193 stories from individual countries show how climate change is reshaping reality everywhere, from dying coral reefs in Fiji to disappearing oases in Morocco and far, far beyond.

The role of our leaders: Writing at the end of 2020, Al Gore, the 45th vice president of the United States, found reasons for optimism in the Biden presidency, a feeling perhaps borne out by the passing of major climate legislation. That doesn’t mean there haven’t been criticisms. For example, Charles Harvey and Kurt House argue that subsidies for climate capture technology will ultimately be a waste.

The worst climate risks, mapped: In this feature, select a country, and we’ll break down the climate hazards it faces. In the case of America, our maps, developed with experts, show where extreme heat is causing the most deaths.

What people can do: Justin Gillis and Hal Harvey describe the types of local activism that might be needed, while Saul Griffith points to how Australia shows the way on rooftop solar. Meanwhile, small changes at the office might be one good way to cut significant emissions, writes Carlos Gamarra.

A.Z.A. facilities report spending approximately $231 million annually on conservation projects. For comparison, in 2018, they spent $4.9 billion on operations and construction. I find one statistic particularly telling about their priorities: A 2018 analysis of the scientific papers produced by association members between 1993 and 2013 showed that just about 7 percent of them annually were classified as being about “biodiversity conservation.”

Zoos accredited by the A.Z.A. or the European Association of Zoos and Aquaria have studbooks and genetic pedigrees and carefully breed their animals as if they might be called upon at any moment to release them, like Noah throwing open the doors to the ark, into a waiting wild habitat. But that day of release never quite seems to come.

There are a few exceptions. The Arabian oryx, an antelope native to the Arabian Peninsula, went extinct in the wild in the 1970s and then was reintroduced into the wild from zoo populations. The California condor breeding program, which almost certainly saved the species from extinction, includes five zoos as active partners. Black-footed ferrets and red wolves in the United States and golden lion tamarins in Brazil — all endangered, as well — have been bred at zoos for reintroduction into the wild. An estimated 20 red wolves are all that remain in the wild.

The A.Z.A. says that its members host “more than 50 reintroduction programs for species listed as threatened or endangered under the Endangered Species Act.” Nevertheless, a vast majority of zoo animals (there are 800,000 animals of 6,000 species in the A.Z.A.’s zoos alone) will spend their whole lives in captivity, either dying of old age after a lifetime of display or by being culled as “surplus.”

The practice of killing “surplus” animals is kept quiet by zoos, but it happens, especially in Europe. In 2014, the director of the E.A.Z.A. at the time estimated that between 3,000 and 5,000 animals are euthanized in European zoos each year. (The culling of mammals specifically in E.A.Z.A. zoos is “usually not more than 200 animals per year,” the organization said.) Early in the pandemic, the Neumünster Zoo in northern Germany coolly announced an emergency plan to cope with lost revenue by feeding some animals to other animals, compressing the food chain at the zoo like an accordion, until in the worst-case scenario, only Vitus, a polar bear, would be left standing. The A.Z.A.’s policies allow for the euthanasia of animals, but the president of the association, Dan Ashe, told me, “it’s very rarely employed” by his member institutions.

Mr. Ashe, a former director of the U.S. Fish and Wildlife Service, suggested that learning how to breed animals contributes to conservation in the long term, even if very few animals are being released now. A day may come, he said, when we need to breed elephants or tigers or polar bears in captivity to save them from extinction. “If you don’t have people that know how to care for them, know how to breed them successfully, know how to keep them in environments where their social and psychological needs can be met, then you won’t be able to do that,” he said.

The other argument zoos commonly make is that they educate the public about animals and develop in people a conservation ethic. Having seen a majestic leopard in the zoo, the visitor becomes more willing to pay for its conservation or vote for policies that will preserve it in the wild. What Mr. Ashe wants visitors to experience when they look at the animals is a “sense of empathy for the individual animal, as well as the wild populations of that animal.”

I do not doubt that some people had their passion for a particular species, or wildlife in general, sparked by zoo experiences. I’ve heard and read some of their stories. I once overheard two schoolchildren at the Smithsonian’s National Zoo in Washington confess to each other that they had assumed that elephants were mythical animals like unicorns before seeing them in the flesh. I remember well the awe and joy on their faces, 15 years later. I’d like to think these kids, now in their early 20s, are working for a conservation organization somewhere. But there’s no unambiguous evidence that zoos are making visitors care more about conservation or take any action to support it. After all, more than 700 million people visit zoos and aquariums worldwide every year, and biodiversity is still in decline.

In a 2011 study, researchers quizzed visitors at the Cleveland, Bronx, Prospect Park and Central Park zoos about their level of environmental concern and what they thought about the animals. Those who reported “a sense of connection to the animals at the zoo” also correlated positively with general environmental concern. On the other hand, the researchers reported, “there were no significant differences in survey responses before entering an exhibit compared with those obtained as visitors were exiting.”

2008 study of 206 zoo visitors by some members of the same team showed that while 42 percent said that the “main purpose” of the zoo was “to teach visitors about animals and conservation,” 66 percent said that their primary reason for going was “to have an outing with friends or family,” and just 12 percent said their intention was “to learn about animals.”

The researchers also spied on hundreds of visitors’ conversations at the Bronx Zoo, the Brookfield Zoo outside Chicago and the Cleveland Metroparks Zoo. They found that only 27 percent of people bothered to read the signs at exhibits. More than 6,000 comments made by the visitors were recorded, nearly half of which were “purely descriptive statements that asserted a fact about the exhibit or the animal.” The researchers wrote, “In all the statements collected, no one volunteered information that would lead us to believe that they had an intention to advocate for protection of the animal or an intention to change their own behavior.”

People don’t go to zoos to learn about the biodiversity crisis or how they can help. They go to get out of the house, to get their children some fresh air, to see interesting animals. They go for the same reason people went to zoos in the 19th century: to be entertained.

A fine day out with the family might itself be justification enough for the existence of zoos if the zoo animals are all happy to be there. Alas, there’s plenty of heartbreaking evidence that many are not.

In many modern zoos, animals are well cared for, healthy and probably, for many species, content. Zookeepers are not mustache-twirling villains. They are kind people, bonded to their charges and immersed in the culture of the zoo, in which they are the good guys.

But many animals clearly show us that they do not enjoy captivity. When confined they rock, pull their hair and engage in other tics. Captive tigers pace back and forth, and in a 2014 study, researchers found that “the time devoted to pacing by a species in captivity is best predicted by the daily distances traveled in nature by the wild specimens.” It is almost as if they feel driven to patrol their territory, to hunt, to move, to walk a certain number of steps, as if they have a Fitbit in their brains.

The researchers divided the odd behaviors of captive animals into two categories: “impulsive/compulsive behaviors,” including coprophagy (eating feces), regurgitation, self-biting and mutilation, exaggerated aggressiveness and infanticide, and “stereotypies,” which are endlessly repeated movements. Elephants bob their heads over and over. Chimps pull out their own hair. Giraffes endlessly flick their tongues. Bears and cats pace. Some studies have shown that as many as 80 percent of zoo carnivores, 64 percent of zoo chimps and 85 percent of zoo elephants have displayed compulsive behaviors or stereotypies.

Elephants are particularly unhappy in zoos, given their great size, social nature and cognitive complexity. Many suffer from arthritis and other joint problems from standing on hard surfaces; elephants kept alone become desperately lonely; and all zoo elephants suffer mentally from being cooped up in tiny yards while their free-ranging cousins walk up to 50 miles a day. Zoo elephants tend to die young. At least 20 zoos in the United States have already ended their elephant exhibits in part because of ethical concerns about keeping the species captive.

Many zoos use Prozac and other psychoactive drugs on at least some of their animals to deal with the mental effects of captivity. The Los Angeles Zoo has used Celexa, an antidepressant, to control aggression in one of its chimps. Gus, a polar bear at the Central Park Zoo, was given Prozac as part of an attempt to stop him from swimming endless figure-eight laps in his tiny pool. The Toledo Zoo has dosed zebras and wildebeest with the antipsychotic haloperidol to keep them calm and has put an orangutan on Prozac. When a female gorilla named Johari kept fighting off the male she was placed with, the zoo dosed her with Prozac until she allowed him to mate with her. A 2000 survey of U.S. and Canadian zoos found that nearly half of respondents were giving their gorillas Haldol, Valium or another psychopharmaceutical drug.

Some zoo animals try to escape. Jason Hribal’s 2010 book, “Fear of the Animal Planet,” chronicles dozens of attempts. Elephants figure prominently in his book, in part because they are so big that when they escape it generally makes the news.

Mr. Hribal documented many stories of elephants making a run for it — in one case repairing to a nearby woods with a pond for a mud bath. He also found many examples of zoo elephants hurting or killing their keepers and evidence that zoos routinely downplayed or even lied about those incidents.

Elephants aren’t the only species that try to flee a zoo life. Tatiana the tiger, kept in the San Francisco Zoo, snapped one day in 2007 after three teenage boys had been taunting her. She somehow got over the 12-foot wall surrounding her 1,000-square-foot enclosure and attacked one of the teenagers, killing him. The others ran, and she pursued them, ignoring all other humans in her path. When she caught up with the boys at the cafe, she mauled them before she was shot to death by the police. Investigators found sticks and pine cones inside the exhibit, most likely thrown by the boys.

Apes are excellent at escaping. Little Joe, a gorilla, escaped from the Franklin Park Zoo in Boston twice in 2003. At the Los Angeles Zoo, a gorilla named Evelyn escaped seven times in 20 years. Apes are known for picking locks and keeping a beady eye on their captors, waiting for the day someone forgets to lock the door. An orangutan at the Omaha Zoo kept wire for lock-picking hidden in his mouth. A gorilla named Togo at the Toledo Zoo used his incredible strength to bend the bars of his cage. When the zoo replaced the bars with thick glass, he started methodically removing the putty holding it in. In the 1980s, a group of orangutans escaped several times at the San Diego Zoo. In one escape, they worked together: One held a mop handle steady while her sister climbed it to freedom. Another time, one of the orangutans, Kumang, learned how to use sticks to ground the current in the electrical wire around her enclosure. She could then climb the wire without being shocked. It is impossible to read these stories without concluding that these animals wanted out.

“I don’t see any problem with holding animals for display,” Mr. Ashe told me. “People assume that because an animal can move great distances that they would choose to do that.” If they have everything they need nearby, he argued, they would be happy with smaller territories. And it is true that the territory size of an animal like a wolf depends greatly on the density of resources and other wolves. But then there’s the pacing, the rocking. I pointed out that we can’t ask animals whether they are happy with their enclosure size. “That’s true,” he said. “There is always that element of choice that gets removed from them in a captive environment. That’s undeniable.” His justification was philosophical. In the end, he said, “we live with our own constraints.” He added, “We are all captive in some regards to social and ethical and religious and other constraints on our life and our activities.”

What if zoos stopped breeding all their animals, with the possible exception of any endangered species with a real chance of being released back into the wild? What if they sent all the animals that need really large areas or lots of freedom and socialization to refuges? With their apes, elephants, big cats, and other large and smart species gone, they could expand enclosures for the rest of the animals, concentrating on keeping them lavishly happy until their natural deaths. Eventually, the only animals on display would be a few ancient holdovers from the old menageries, animals in active conservation breeding programs and perhaps a few rescues.

Such zoos might even be merged with sanctuaries, places that take wild animals that because of injury or a lifetime of captivity cannot live in the wild. Existing refuges often do allow visitors, but their facilities are really arranged for the animals, not for the people. These refuge-zoos could become places where animals live. Display would be incidental.

Such a transformation might free up some space. What could these zoos do with it, besides enlarging enclosures? As an avid fan of botanical gardens, I humbly suggest that as the captive animals retire and die off without being replaced, these biodiversity-worshiping institutions devote more and more space to the wonderful world of plants. Properly curated and interpreted, a well-run garden can be a site for a rewarding “outing with friends or family,” a source of education for the 27 percent of people who read signs and a point of civic pride.

I’ve spent many memorable days in botanical gardens, completely swept away by the beauty of the design as well as the unending wonder of evolution — and there’s no uneasiness or guilt. When there’s a surplus, you can just have a plant sale.
