Eating Beef Is Worse for the Environment Than Eating Grains and Vegetables.
Near people accept heard it past now: Our meat habit is bad for the world. Polling suggests that tens of millions of people are taking this message seriously: One in 4 Americans said they tried to cut back on meat in the last twelvemonth, and half of those cited environmental concerns as a major reason. The popular food site Epicurious recently announced they've stopped publishing recipes with beef in them, because of beefiness's climate impacts, setting off the latest round of discussion on meat'due south furnishings on the surroundings.
Cutting meat consumption is every bit smart an idea as advertised. Industrial farming — the source of 99 per centum of the meat Americans eat — provides the globe with inexpensive meat, but it does so at a terrible environmental and moral cost.
Where it gets complicated is when people make up one's mind which meat, exactly, they'll be cutting dorsum on. Often, it's beef that loses out in that calculus. And oftentimes, the messaging is that nosotros can salve the world by switching out our beef consumption for chicken.
The trouble with this bulletin is that switching beef for chicken basically amounts to trading one moral ending for another.
The environmental reasons for cutting beef from one'southward diet are clear. Most of the climate impact of creature agronomics comes from raising cows for beef. Cows produce methane, a greenhouse gas that is a major contributor to global warming; information technology's much more potent than carbon dioxide. Transitioning away from eating beef to eating other manufacturing plant-farmed creature products undoubtedly reduces the carbon impact of a person's nutrition.
Just the transition away from beefiness can end upwardly being a Pyrrhic victory if it drives up the world's speedily rising craven consumption. That ends up swapping one disaster — the climate crisis and beef farming's role in it — for another: the moral disaster of industrial chicken production.
To put it simply, it takes many, many more chicken lives than cow lives to feed people. Cows are big, so raising one produces most 500 pounds of beef — and at the charge per unit at which the average American eats beef, it takes nigh 8.5 years for one person to swallow ane moo-cow. But chickens are much smaller, producing just a few pounds of meat per bird, with the average American eating about ane whole chicken every two weeks. To put it some other way, each year we eat about 23 chickens and just over 1-tenth of i cow (and about a tertiary of 1 pig).

The option to swap beef for chicken is further compounded by the differences in their quality of life. Cows are raised for slaughter on pastures and feedlots — enclosed spaces where they're fed grain in training for slaughter. Virtually animate being well-existence experts say that the life of a cow raised for beef is punctuated past traumatic events and cut needlessly short, but it's not ceaseless torture.
On the other hand, factory-farmed chickens — and that'southward 99 per centum of all chickens we swallow — have an awful life from the moment they're born to the moment they're slaughtered. The nigh efficient way to raise chickens is in massive, ammonia-high-strung, noisy warehouses, where the birds grow so rapidly (due to genetic choice for excessive size) that their legs tin't support their weight. They live near six weeks and so are killed.
And so switching from cows to chickens is a way to somewhat reduce carbon emissions — but it comes with a massive increment in creature suffering.
Choosing between the two is a knotty dilemma that tends non to be discussed often. But this tension isn't inevitable. After all, climate advocates and brute advocates are on the same side: supporting a transition away from industrial agronomics. And most people care well-nigh both animals and the surround, so addressing mill farming is a simple win-win.
The solution to manufacturing plant farming's many harms tin't be shuffling consumers betwixt chicken and beefiness depending which of their devastating impacts is on the top of our minds. And consumers shouldn't take as inevitable the choice between torturing animals and dramatically worsening global warming. There is a path to a food system that doesn't force the states to choose, but nosotros're going to need to take much bigger steps, in terms of policy and consumer option, to get in that location.
The climate impacts of fauna agriculture
There'southward no manner around it: Raising beef actually is bad for the earth.
About 15 pct of all global greenhouse gas emissions come from livestock. Beef is the biggest culprit, bookkeeping for about 65 percent of all greenhouse gas emissions from livestock. Cattle produce marsh gas, and they also require lots of carbon-intensive land conversion and carbon-intensive feed. According to the Earth Resources Institute, an environmental research nonprofit, beef requires twenty times more than state and emits 20 times more greenhouse gas emissions per gram of edible protein than common plant proteins, like beans.
Beef'due south defenders have argued that it doesn't have to be that style. Proposals from feeding cattle seaweed in society to reduce their methyl hydride emissions to "regenerative farming" that tin ameliorate soil and land have been aired, and some take been implemented on a small-scale scale.
Just American consumers shouldn't kid themselves: If y'all buy beef from a grocery store shelf or in a restaurant in America, unless y'all go very far out of your fashion to trace, source, and verify the sustainable history of that meat, you lot're getting the product of a carbon-intensive industrial process.
Epicurious nodded to this reality in its proclamation that information technology would terminate publishing beefiness recipes: "Nosotros know that some people might assume that this conclusion signals some sort of vendetta confronting cows — or the people who eat them. Merely this decision was not made because nosotros detest hamburgers (we don't!). Instead, our shift is solely about sustainability, about not giving airtime to i of the globe's worst climate offenders. We think of this determination as non anti-beefiness but rather pro-planet."
A May 20 article in the New York Times virtually the rise of "climatarians" underscored the emerging primacy of climate in people's dietary choices, noting that climate-conscious eaters accept moved in a meatless management, simply that many even so believe that "chicken or lamb are much ameliorate choices than beef."
It's entirely understandable that some consumers have decided it'due south time to motility abroad from beef. And yes, individual consumer decisions do matter: Researchers accept studied what's called the elasticity of supply for meat — that is, how much consumer demand affects production — and determined that when consumers demand fewer hamburgers, fewer cows are raised.
Just whether that'southward, on the whole, a good affair depends a lot on what y'all choose instead.
The animate being-cruelty bending
It's no fun to exist a cow on a factory farm. But animal welfare experts agree: Being a chicken is much worse.
That's because of the commercial incentives behind both cow and chicken production. Ranchers take found it most efficient to enhance cows outdoors on pasture and then fatten them for slaughter on feedlots. There's a lot incorrect with how nosotros raise them — cows are painfully dehorned, mass distribution of antibiotics keeps them healthy at the expense of breeding antibiotic resistance, and while there's a federal law that requires pigs and cattle to be rendered unconscious prior to slaughter, it's not e'er followed and simply minimally enforced.
But chickens have it much worse. The cheapest way to raise chickens is in massive, crowded indoor warehouses where they never see the sunday. Over time, companies take bred chickens to grow and so fast their joints fail as they reach full size. Observational studies suggest they spend much of their time sitting still, in besides much pain to motility.
"In most cases, they suffer far more than beef cattle, who take more than legal protections, suffer fewer health problems, and are generally less intensively confined," Leah Garces, the president of Mercy for Animals, has argued.
And while a cow suffers and is slaughtered to produce around 500 pounds of meat, a craven produces about 4 to 5 pounds of meat. And then a switch from beef to chicken is actually a switch from a tough life for one cow to an awful life for around 100 chickens.
That's why many advocates calling for an end to industrial farming take mixed feelings nigh the movement against beef. Is it correct to try to save some carbon emissions by causing even more fauna suffering?
And craven is no panacea for the climate either. "Its impact on the climate only looks benign when compared with beef's," Garces points out. "Greenhouse gas emissions per serving of poultry are 11 times college than those for one serving of beans, so swapping beef with chicken is alike to swapping a Hummer with a Ford F-150, non a Prius."
Some other frequently proposed choice is switching to fish. But aquaculture, likewise, causes intense fauna suffering and massive ecological consequences. At that place simply aren't humane, sustainable, widely available, and cheap meats.
Giving consumers better choices
Consumers who are reconsidering their meat consumption — for the sake of animals, the planet, or both — are doing a courageous thing, and the point of observing the added complications of this choice isn't to discourage them. Fixing our cleaved nutrient system is going to require substantial policy and corporate changes, as well equally consumers making better choices. The beef versus chicken chat is part of how we get in that location.
Only what the dilemma lays bare is that there's no meat consumption that will salve the earth. Meat is i of the most popular foods, and nevertheless building a meliorate world is going to require inducing consumers to switch abroad from it — and not but switch between different categories of meat as they weigh the different environmental and moral catastrophes it causes.
That's why some beast advocates in the last few years take switched from convincing consumers to go vegan — which tin exist likewise big of a leap for many — to advocating for plant-based meat products. These establish-based products are already difficult to distinguish from the originals, while having a lighter carbon footprint and no affect on animals. If you avoid beef past switching to plant-based meat products, yous really are improving the earth and improving conditions for the humans and animals that live on it.
But despite all these complications, when prominent food sites take beef out of their lineup or when Americans tell pollsters they're trying to cut back on beef, information technology's crusade for optimism — even though in the brusque term, depending what they replace information technology with, information technology could make things worse. Our food organization delivers meat cheaply at an awful price. Starting more conversations well-nigh that toll and how we tin mitigate it is a skillful thing, fifty-fifty if it'due south a chat a long way from a satisfying resolution.
Correction, May 24: A previous version of this commodity misstated a resource-per-calorie comparison of meat and vegetables. Information technology has been updated to state that "beef requires xx times more land — and emits 20 times more greenhouse gas emissions — per gram of edible protein than common institute proteins."
