Maybe essentially the most essential thought for understanding our species’ future on this planet boils down to 2 boring phrases: land use.
To mitigate local weather change, people might want to extract essential minerals to construct huge numbers of photovoltaic cells and wind generators. We’ll want hundreds of thousands of tons of copper to wire continent-spanning energy grids. However essentially the most immutable useful resource constraint we face — the one we are able to’t mine extra of — is land.
Though many people don’t see it, as a result of most people now dwell in city areas, the story of land constraints can be a story about agriculture, which devours practically half of our planet’s liveable land; city and suburban areas take up solely a tiny fraction.
We’re not utilizing all that farmland very properly. Beef farming, for instance, occupies “practically half the world’s agricultural land to supply simply 3 p.c of its energy,” the journalist Michael Grunwald writes in his new ebook, We Are Consuming the Earth. Partially as a result of it consumes a lot land, agriculture contributes between 1 / 4 and a 3rd of all greenhouse gasoline emissions, and as humanity’s numbers climb, its footprint will swell. “If present traits maintain, the world’s farmers will clear a minimum of a dozen extra Californias’ price of land to fill practically 10 billion human bellies by 2050,” Grunwald writes.
Grunwald’s ebook — a energetic, reportorial world tour by way of the misunderstood science and politics of agriculture, typically defined through Gen X film references — is amongst a slate of latest titles that I like to consider because the abundance agenda of meals.
Abundance, Ezra Klein and Derek Thompson’s bestselling it-girl of wonk manifestos, shares mental DNA with a rising set of concepts bringing supply-side financial rules to the way forward for farming. Simply as we are able to’t resolve the housing disaster or the inexperienced vitality hole with a politics of shortage, we are able to’t repair agriculture’s planetary affect by merely producing much less meals. We’ve got to develop sufficient meals to affordably and sustainably feed a world of 8 billion and counting. And since there’s a tough restrict on land, which means determining find out how to squeeze extra meals out of our treasured acreage.
The proposed options may shock you. They don’t seem to be crunchy farming philosophies like native agriculture or so-called regenerative ranching — woefully inefficient, low-productivity programs that, if deployed at scale, would imply mowing down the world’s remaining forests, accelerating local weather change and mass extinction. That’s as a result of wild, carbon-sequestering ecosystems are our greatest pure defenses in opposition to local weather change, which is one thing that no agricultural sample can replicate. “Each farm, even the scenic ones with crimson barns and rolling hills that artists paint and writers sentimentalize, is a form of environmental crime scene,” Grunwald writes. And at present, “international agriculture is shifting south, towards tropical forests and wetlands which can be the world’s most dear carbon sinks,” just like the Amazon.
Meaning crucial determinant of agriculture’s planetary affect is how a lot land it sucks up — what Grunwald calls “the eating-the-earth drawback.” By this measure, standard, intensive, industrial crop farming like that practiced throughout the US, and closely criticized by many environmentalists, outperforms natural agriculture or low-yield farming widespread in low-income nations, for the easy purpose that it produces essentially the most meals on the least land (although there may be, to make sure, nuance to this debate).
We Are Consuming the Earth is joined by a grumpier, extra tutorial provocation on meals sustainability. Meals Battle, by UC Davis agricultural economist Richard Sexton, decries the insurance policies being applied all over the world, typically within the identify of serving to the surroundings, that may make farming much less productive and fewer sustainable, and meals costlier. “By no means have governments actively intervened to implement insurance policies assured to scale back meals manufacturing the way in which they do at present and promise to do into the longer term,” he argues, dismantling approaches starting from mindless ethanol mandates within the US and elsewhere to Europe’s pro-organic and anti-GMO insurance policies.
These are clever, extremely well timed books that get many issues proper, surfacing the misguided pastoral fantasies and deadly misunderstandings of land use that make it onerous for us to pursue sane agricultural insurance policies. They encourage due respect for a contemporary industrial meals system that, for all its issues, has achieved spectacular feats of productiveness essential to assist a planet of billions of individuals.
However their emphasis on intensification additionally leads them someplace way more ominous: a protection of the worst a part of our meals system, one that may result in ever-more horrifying ranges of struggling and loss of life.
The rise of anti-anti-factory farming
Repairing our meals system is so confoundingly tough partly as a result of it typically feels extra intractable than it must be. We already know we might alleviate plenty of the issue by consuming much less meat and dairy — the meals equal of coal energy — and extra crops, however convincing customers to try this by way of both coverage or suasion is basically, actually onerous. (Consider me, I strive).
“One American pollster instructed me meat taxes have been essentially the most unpopular coverage he ever surveyed, ‘up there with veterans’ advantages for ISIS,’” Grunwald grimly remarks. And one of many surest bets you possibly can place on the longer term, as each authors level out, is that as folks in low- and middle-income nations change into richer, they are going to eat tons extra animal merchandise. People already slaughter an eye-watering 80 billion land animals per 12 months, a quantity that may proceed to soar.
Resigned to that dismal actuality, each We Are Consuming the Earth and Meals Battle mirror an concept that’s more and more prevalent in way forward for meals debates — that manufacturing unit farms, regardless of their cruelty, are a vital evil. Name it anti-anti-factory farming.
The reasoning is simple sufficient. Animal agriculture takes up a lot of land and assets — that’s why meat is dangerous for the surroundings within the first place. The one approach to produce it at scale with out blowing up local weather targets and clearing rainforests is to lift animals as intensively as attainable by way of what’s referred to as “sustainable intensification.”
Manufacturing facility farms don’t exist merely to be evil, in spite of everything, however quite as a result of they produce animal merchandise with the fewest attainable inputs. Simply as a lot as these books puncture Michael Pollan-esque pipe goals of feeding the world with pasture-raised steak, additionally they have little persistence for animal rights activists who need to regulate manufacturing unit farming out of existence.
Thus included on Sexton’s checklist of misguided insurance policies are animal welfare legal guidelines like California’s Proposition 12, which ban a number of the most excessive types of confinement for cattle, together with caging feminine breeding pigs in crates so small they’re similar to spending a complete human life trapped inside a coffin.
“Insurance policies being imposed within the identify of animal welfare scale back the productiveness of those animals and lift the prices of manufacturing animal merchandise,” he writes. In equity to Sexton, whom I’ve an infinite quantity of respect for and have interviewed for quite a few tales, he suggests what he argues is an alternate, less expensive path to reaching the welfare advantages of Prop 12. “I like animals and wish them to be handled properly,” he writes.

Grunwald extra gingerly suggests manufacturing unit farms stay an inevitable, if inhumane and never ideally suited, a part of meals manufacturing. In a controversial New York Occasions essay final December, he argued, “the inconvenient reality is that manufacturing unit farms are one of the best hope for producing the meals we are going to want with out obliterating what’s left of our pure treasures and vaporizing their carbon into the ambiance.”
One of many surest, most practical methods to scale back meat’s outsize land and carbon footprints this century, Grunwald writes, is for diets to exchange beef with poultry and pork, that are far decrease in local weather affect. However that commerce can be morally calamitous — it takes way more particular person chickens and pigs to supply the identical quantity of meat as beef cattle, and people animals are handled far worse.
The anti-anti-factory farming ethos is actually a manner of taking a look at our meals system. There’s a brutal logic to it that anti-factory farm advocates need to study to cope with.
Take dairy cows as only one illustrative instance: Breeding them for maximal productiveness has meant that “since World Battle II, the US dairy herd has shrunk by two-thirds, but produces two-thirds extra milk,” Grunwald writes. Had that not occurred, we’d have extra dairy cows emitting extra greenhouse gases, and we’d probably have cleared extra land and harmed extra ecosystems to develop the crops that feed them. In a lot of the remainder of the world, dairy herds are a lot much less productive, thereby consuming extra assets and polluting the local weather extra for each gallon of milk produced.
But America’s hyper-productive turbo-cows have come at a extreme value to animal welfare. Dairy cows are a number of the most depressing animals in our meals system: Like all mammals, they solely make milk after giving beginning, to feed their infants, however they’ve been bred to supply excess of a calf would drink. These astronomical yields destroy the dairy cow’s physique, forcing her to channel “freakish” quantities of vitality into milk manufacturing, because the meals historian Anne Mendelson has written. (One may argue that the counterfactual can be even worse: a world with extra, less-productive dairy cows, every enduring a lifetime of continuous being pregnant and separation from their calves. However, the sheer extremity of the fashionable turbo-cow’s struggling, and the prospect of bringing many extra of them into the world, crosses an ethical threshold.)
All this for a meals that also, even after cows have been pushed past the bounds of decency, stays considerably worse for the surroundings than merely consuming plant-based meals. So is industrial milk actually a win for the planet?
One among my favourite visualizations the worldwide meals system comes from Our World in Information:
Plant-based meals — that’s, the whole lot that’s not meat, dairy, and eggs — already provide greater than 80 p.c of the world’s energy, and practically two-thirds of our protein, with simply 16 p.c of world agricultural land. One conclusion you can draw from this chart is that animal agriculture is so inherently inefficient — we develop feed crops to lift animals that we then slaughter to feed ourselves — that now we have to work onerous to seek out methods of creating it extra productive. One other manner of taking a look at it’s that animal agriculture is so inefficient — and, by the way in which, it comes at an unthinkable ethical value, and it’d begin the following pandemic — that it will be the definition of lunacy to squander restricted international carbon budgets to supply an ever-greater share of our meals this manner.
However there’s no single council of humanity that may make that call for our species — solely billions of people making market decisions. And so they have proven each signal that they’re going to hold consuming meat.
So Grunwald requires an all-of-the-above method. We Are Consuming the Earth roots for the success of meat options like plant-based and cell-cultivated meat — and it made me really feel extra optimistic about their future than I’ve in a very long time — simply as a lot because it embraces intensive animal manufacturing. Innovation can even make intensive crop agriculture extra planet-friendly, as Grunwald explores, by making it much less depending on inputs that hurt wildlife, like chemical pesticides.
The logic of anti-anti-factory farming genuinely challenged me, as a result of as unimaginable as its decisions really feel — will we torture a number of billion extra animals per 12 months, or let the Amazon burn? — they’re actual trade-offs that policymakers face daily.
It’s onerous to check the despoiling of irreplaceable ecological wonders to the infernal horror of the manufacturing unit farm in accordance with a cost-benefit evaluation, as a result of they really feel incommensurate. But when we tried to do it truthfully, I’m unsure the reply can be as clear as manufacturing unit farming’s defenders recommend. Their case solely works as a result of meals programs evaluation sees animals as financial inputs, not a lot completely different than a bushel of wheat, quite than as who they are surely. It doesn’t significantly have interaction with what it actually means to cattle for meals — the incessant ache of a contemporary broiler hen, or the mind-numbing despair of a caged mom pig used as a reproductive machine.
So let me provide yet another new ebook advice: my good friend the thinker John Sanbonmatsu’s The Omnivore’s Deception. One other rebuke of Michael Pollan and his protection of consuming animals, it’s the uncommon ebook that unshrinkingly names our tyranny over animals as a “civilizational error,” as Sanbonmatsu writes. It’s “about what occurs after we arrange our society, financial system, and every day lives round a radical evil, then have interaction in self-deception to maintain the reality of that evil from ourselves.”
We Are Consuming the Earth is, to a fantastic extent, a piece of unsentimental pragmatism, which makes the spirited case for principled idealism within the ebook’s ultimate moments all of the stronger. Typically progress relies on a “refusal to learn the room and cease saying issues no one wished to listen to,” Grunwald writes. “It pays to maintain working and combating the great struggle, as a result of perhaps one thing good will occur. Perhaps it received’t, however should you don’t hold working and combating, it positively received’t.”
We must always have a look at animal agriculture the identical manner. We might proceed turning our planet into an enormous manufacturing unit farm, however then, what are we even doing all this for? If we proceed to disregard one of many biggest atrocities of our time — and develop it even additional — what can be the purpose of constructing such a world?
All around the globe, there are animal advocates urging their fellow people to alter course, and the one manner we’ll really feel our manner out of the manufacturing unit farm entice is to decide to that job. We don’t know if we’ll ever persuade humanity to desert the “radical evil” of manufacturing unit farming, however it will be an abdication to surrender making an attempt.
