For anyone who has ever stared down the abyss of factory farming data, the psychological weight can be paralyzing. Billions of land animals are slaughtered globally every year—hundreds of millions every single day, and thousands in the time it takes to read a single sentence. When faced with figures that are as abysmal as they are mind-numbing, the typical human response is self-preservation through detachment: people simply tune out and ignore the problem altogether.
For those who do let the reality sink in, the traditional prescribed remedy is an absolute lifestyle overhaul: adopt a strictly vegetarian or vegan diet. Some make it stick. The author of this approach, for instance, has maintained a meat-free lifestyle for two decades. However, behavioral data from organizations like Faunalytics indicates that for the vast majority of people, full-scale dietary conversion does not stick. The friction of completely abandoning familiar diets proves too high.
Yet, groundbreaking new research reveals that a binary choice—eat meat or go entirely plant-based—is a false dichotomy. Ditching beef entirely is not the only path to making a profound impact on animal welfare. Instead, a burgeoning body of research highlights an alternative strategy that is nearly as effective for reducing total animal suffering and exponentially easier for the average consumer to implement: eating fewer small animals.
The realization that animal products carry vastly different ethical footprints has led researchers to formalize a concept known in advocacy circles as the “small body problem.” Recently published by researcher Chris Bryant—an honorary research associate at the University of Bath—in collaboration with the animal welfare research group Faunalytics, a new analysis seeks to quantify the hidden toll of our plates.
The core premise is stark: the sheer number of animals who suffer to produce food, and the intensity of that suffering, varies wildly depending on the species. Large animals, such as beef cattle, are farmed in much lower numbers and yield massive quantities of meat per individual. Conversely, smaller-bodied animals like farmed fish, chickens, and shrimp yield very little meat per individual.
Consequently, to produce a single pound of consumable protein, the industrial food system must breed, confine, and slaughter exponentially more small animals than large ones. By examining food production through a "suffering footprint"—modeled similarly to the carbon footprints popularized by the climate movement—researchers are offering a practical middle ground. For consumers who feel overwhelmed by the prospect of veganism, simply targeting small animals and poultry provides a high-impact, highly manageable way to vote against industrial cruelty.
Detailed Chronology: Unpacking the "Small Body Problem"
To understand how researchers arrived at these counterintuitive conclusions, it is necessary to examine the methodology behind the Faunalytics and Bryant study. For years, food systems analysis has been dominated by environmental metrics: greenhouse gas emissions, land use, and water footprints. While invaluable for tackling climate change, these metrics left a blind spot regarding the subjective experience of the sentient creatures caught inside the supply chain.
Bridging the Data Gap
Allison Troy, research director at Faunalytics, noted that the motivation for the study stemmed from a noticeable void in consumer awareness. "We are somewhat used to seeing, especially from the climate movement, data and other kinds of tools that help us think about the carbon footprint of the choices that we make, and we think that’s really important," Troy explains. "Pero we felt like there was a gap in terms of thinking about more of a ‘suffering footprint’ when it comes to choosing to purchase animal products."
To fill this gap, researchers embarked on a comprehensive data-synthesis project. They pulled extensive agricultural statistics from the United States Department of Agriculture (USDA), the United Nations Food and Agriculture Organization (FAO), and various independent agricultural databases. Their goal was straightforward: calculate how much edible meat, milk, or eggs a typical farmed animal produces across its lifespan in the industrial system.
Factoring in the Invisible Chain
The researchers went a step further than previous models by incorporating indirect sources of animal suffering. For instance, many carnivorous or omnivorous farmed fish species—such as farmed salmon—are fed meal and oil derived from wild-caught or smaller farmed "feeder" fish. These secondary casualties were factored directly into the equations to construct a holistic accounting of the aquatic supply chain.
Once the datasets were unified, the research team crunched the numbers to answer two pivotal questions per pound of food:
How many days of animal suffering are embedded in a given product?
How many individual animal lives are ended to produce that single pound?
The results challenged conventional wisdom about which foods inflict the greatest harm.
Supporting Context & Metrics: The Shocking Scale of Small Animals
The findings of the Faunalytics analysis upend many common assumptions about ethical eating, particularly regarding seafood and poultry.
The Shrimp Paradox
At the apex of the "suffering footprint" sits an animal few people associate with factory farming: the shrimp. Due to their minuscule size, colossal numbers of shrimp must be harvested, transported, and processed to yield a single serving of seafood.
According to the data, a single bite of shrimp scampi results in drastically more days of animal suffering—and requires the destruction of far more individual lives—than consuming an entire beef burger. A family sitting down for a steak dinner consumes roughly half a percent of a single cow, spreading that animal’s life and death across dozens of heavy portions. By contrast, eating a plate of shrimp means consuming dozens of distinct, sentient lives in a single sitting.
The Dominance of Poultry
While seafood carries an immense per-pound suffering footprint, it does not form a major baseline component of most Western diets, with many consumers eating none at all. When seafood is isolated from the equation, the data points directly to poultry—chicken meat, turkey meat, and eggs—as the single largest driver of dietary animal suffering for the average consumer.
Poultry production requires the slaughter of staggering numbers of animals to meet market demand. This disparity is entirely a function of body mass. Because chickens and turkeys are physically small, the industrial machine must churn through millions of birds to match the tonnage yielded by a fraction of the cattle industry.
Furthermore, the welfare conditions for poultry are notoriously bleak. Broiler chickens (raised for meat) have been selectively bred through aggressive genetics to grow so rapidly and heavily that a significant percentage suffer from debilitating skeletal deformities, rendering them unable to stand or walk normally. Meanwhile, approximately half of all egg-laying hens in the United States spend their entire lives crammed into battery cages so small they cannot even fully extend their wings.
Pig and Cattle Realities
None of this is to suggest that larger livestock experience humane treatment. The industrial pork industry routinely subjects piglets to painful mutilations—such as castration and teeth-clipping—without anesthetics or pain relief. Mother pigs (sows) spend successive reproductive cycles locked inside gestation crates so restrictive they cannot turn around. Beef cattle face branding, castration, and dehorning without pain relief before spending their final months packed into dense, muddy feedlots.
However, because these mammals are massive, their individual suffering is distributed across an immense volume of meat. One steer yields hundreds of pounds of beef, meaning the suffering per bite is mathematically lower than it is for a bird or a crustacean.
Official Statements & Expert Perspectives
To maintain journalistic rigor, the study’s scope and limitations must be contextualized through peer review and independent commentary. Because the Faunalytics report was not published in a traditional peer-reviewed journal, we reached out to Trevor Woolley, an assistant professor of agricultural and applied economics at the University of Wisconsin-Madison, for an independent evaluation.
The Value of "Days" as a Metric
Woolley noted that while consumers must treat the figures as analytical estimates rather than absolute mathematical certainties, the framework is fundamentally sound.
"It’s important to recognize that the numbers that are included in their equation are estimates," Woolley stated via email, adding that "the exact numbers should not be taken as precise, but in the right ballpark."
He praised the researchers’ choice of metrics, noting that comparing animal products by the number of individual lives and days spent in production offers a vital lens for consumers.
"Comparing animal products in terms of lives and (especially) days broadly makes sense," Woolley added. "’Days’ is a really nice metric because farm animal species have such drastically different lifespans on the farm."
The Nuance of Suffering Intensity
Despite its utility, experts acknowledge a major limitation inherent in the study: the model does not quantify the severity or quality of suffering experienced by different species.
Allison Troy acknowledges this methodological choice. "We made a choice methodologically to define ‘animal suffering’ as days of life [on a farm]," Troy explains. "And I think that that’s a useful, albeit simple, metric. But it is not the only one."
Consider the qualitative differences: dairy cows live much longer lives than egg-laying hens, often being farmed for several years. While their day-to-day welfare may not always match the acute misery of a caged hen, does the compounding duration of years spent in industrial dairies equal or exceed the intense, shorter suffering of poultry? Current metrics cannot fully answer these nuanced questions, though specialized initiatives like the Welfare Footprint Project continue striving to build more complex multidimensional models.
Future Outlook: A Pragmatic Blueprint for Conscious Eaters
As public awareness of factory farming expands, the conversation around food ethics is shifting away from all-or-nothing dogmas. The traditional demand that consumers instantly transform into puritanical vegans has historically alienated many well-intentioned people, creating an all-or-nothing trap where feeling unable to go fully plant-based leads individuals to abandon animal welfare concerns entirely.
The "small body problem" reframes this dynamic. It suggests that perfection is not the prerequisite for progress. By understanding that a pound of chicken, a plate of shrimp, or a dozen factory-farmed eggs carries an exponentially higher body count and suffering footprint than a serving of beef or pork, consumers are empowered to make strategic, low-friction adjustments.
Practical Takeaways for the Everyday Consumer
Target Poultry First: For meat-eaters unwilling to give up animal protein entirely, reducing consumption of chicken, turkey, and eggs yields an outsized reduction in the number of individual lives impacted.
Scrutinize Seafood: Eliminating or sharply curbing shrimp and small farmed fish consumption removes some of the most densely packed suffering from a diet.
Upgrade Welfare Standards: When purchasing animal products, opting for pasture-raised eggs or higher-welfare certifications can mitigate some of the worst abuses associated with caged systems.
As Marina Bolotnikova aptly noted in prior commentary on the scale of industrial agriculture, the sheer magnitude of the suffering can easily cause the mind to shut down. But by shrinking these cosmic figures down to the manageable level of our own grocery carts, we can think smaller—and, in doing so, radically reduce the amount of pain embedded on our plates.
