Despite clear evidence of the harms of industrial livestock, new research showed that in 2024, 11 leading international finance institutions invested $1.23 billion in factory farming and wider industrial animal agriculture supply chains.
The World Bank’s mission is to “create a world free of poverty on a livable planet.” However, the institution, along with its peer development partners, pumps billions of dollars into factory farming, appearing to turn a blind eye to the significant harm it causes.
We cannot meet the 1.5°C Paris agreement goal without reducing emissions from livestock. Animal agriculture is a leading cause of climate breakdown; already responsible for around 16% of global greenhouse gas emissions and set to rise.
Factory farming is also tearing apart our thriving ecosystems. In Latin America, high demand for industrial grazing pasture and land for growing animal feed has fueled devastating deforestation: 84% of all Latin America’s forest loss in the last 50 years can be attributed to land claimed for livestock farming. Factory farming also pollutes soils and freshwater sources that wild animals and rural communities rely on.
Development banks tasked with tackling poverty and climate change owe it to current and future generations to use their investments to help spur the transition toward more sustainable diets and forms of food production.
Yet despite clear evidence of the harms of industrial livestock, new research I conducted for the Stop Financing Factory Farming Coalition (S3F), based on data from the Early Warning System, showed that in 2024, 11 leading international finance institutions (IFI) invested $1.23 billion in factory farming and wider industrial animal agriculture supply chains. This is five times more than what they spend on more sustainable non-industrial animal agriculture projects. The World Bank and its private sector arm, the International Finance Corporation (IFC), were together responsible for over half the funding for industrial animal agriculture.
One of the investments IFC made last year was a $40 million loan to build a soybean crushing plant in Bangladesh, used to mass-produce animal feed. The soybeans will require an estimated 354,000 hectares of land annually to be grown, and will be sourced from Brazil and Argentina where soy production is associated with destruction of sensitive ecosystems. Communities living near the plant have documented the existing and potential impacts such as the contamination of coastal waters and freshwater sources, which would consequently lead to a reduction in the local fish stocks that local communities rely on to guarantee their livelihoods, and brought their concerns in front of representatives of the U.S. government.
Over the last 20 years, IFC has also made a number of investments in Pronaca, the largest food producer in Ecuador, to expand its factory farm operations. The company has built pig and poultry farms in Santo Domingo de los Tsáchilas, a region home to natural forest and Indigenous Peoples. Local Indigenous communities documented how the farms have polluted water resources that are traditionally used to sustain their livelihoods, forcing community members to migrate to preserve their traditional cultures.
Other IFIs have also made harmful investments. The European Bank for Reconstruction and Development (EBRD) boldly claims all its investments have been Paris-aligned since January 2023; however, recent spending to expand multinational fast food chains in Eastern Europe seem to show a different scenario. During the first half of 2025, the EBRD has provided $10 million for the expansion of KFC and Taco Bell restaurants in the Western Balkans, and proposed an equity investment of $46 million for the expansion of Burger King and Louisiana Popeyes in Poland, Romania, and Czech Republic.
The latter investment would have led to the opening of 600 restaurants in the region, with large adverse impacts in terms of public health and emissions of greenhouse gases. Restaurant Brands International, which owns Burger King and Popeyes, reported approximately 29 million metric tons of carbon dioxide-equivalent emissions along its value chain in 2024, more than the entire emissions of Northern Ireland. Thankfully, following civil society pressure, the investment was not approved by the EBRD’s Board of Directors.
While the overall picture is bleak, there is real room for hope. Between 2023 and 2024, IFI investments in factory farming nearly halved, and investments in more sustainable approaches tripled, from $77 million to US$244 million. Examples of promising investments include the Multilateral Investment Guarantee Agency and the Inter-American Development Bank providing support to smallholder farmers using climate-friendly techniques.
This is clearly good news; however, it remains too early to tell if these figures are a one-off blip, or part of a longer-term trend. My hope is that the next round of investment data will show that harmful investments have dropped further—if not stopped completely—and more sustainable ones additionally increased.
Development banks tasked with tackling poverty and climate change owe it to current and future generations to use their investments to help spur the transition toward more sustainable diets and forms of food production, rather than replicating and expanding the broken systems that are wrecking our planet. By only investing in animal agriculture projects that are sustainable—following agroecological principles such as promoting species diversity and using nature’s resources efficiently—banks can help move us closer toward “a world free of poverty on a livable planet.”
As we reflect on the wonder of migratory birds, and the spotlight focuses on how our cities and communities can be made more bird-friendly, we must also consider how our food system is posing a threat to their very existence.
For migratory and other wild birds, bird flu is a disaster. The U.S. Centers for Disease Control and Prevention, or CDC, states that 169 million U.S. poultry have been affected by highly pathogenic bird flu since January 2022. Yet worldwide, tens of millions of wild birds have died of bird flu—which has also spread to mammals, including over 1,000 US. dairy herds.
Saturday 10 May is World Migratory Bird Day, a global event for raising awareness of migratory birds and issues related to their conservation. The poultry industry and governments like to blame wild birds for bird flu. However, the Scientific Task Force on Avian Influenza and Wild Birds—which includes the United Nations Food and Agriculture Organization (FAO) and the World Organization for Animal Health (WOAH) stresses that wild birds are in fact the victims of highly pathogenic bird flu; they do not cause it. As a recent study states, “This panzootic did not emerge from nowhere, but rather is the result of 20 years of viral evolution in the ever-expanding global poultry population.”
Until recently, the bird flu viruses that circulate naturally in wild birds were usually of low pathogenicity; they generally caused little harm to the birds. It is when it gets into industrial poultry sheds—often on contaminated clothing, feed, or equipment—that low pathogenic avian influenza can evolve into dangerous highly pathogenic avian influenza.
Governments worldwide appear to have no strategy for how to end these regular bird flu outbreaks other than to hope they will eventually die down.
Industrial poultry production, in which thousands of genetically similar, stressed birds are packed into a shed, gives a virus a constant supply of new hosts; it can move very quickly among the birds, perhaps mutating as it does so. In this situation, highly virulent strains can rapidly emerge. The European Food Safety Authority warns that it is important to guard against certain low pathogenic avian influenza subtypes entering poultry farms “as these subtypes are able to mutate into their highly pathogenic forms once circulating in poultry.”
Once highly pathogenic avian influenza strains have developed in poultry farms, they can then be carried back outside—for example, through the large ventilation fans used in intensive poultry operations—and spread to wild birds. The Scientific Task Force states that since the mid-2000s spillover of highly pathogenic bird flu from poultry to wild birds has occurred “on multiple occasions.”
So, low pathogenic bird flu is spread from wild birds to intensive poultry where it can mutate into highly pathogenic bird flu, which then spills over to wild birds and can even return back to poultry in a growing and continuing vicious circle.
Following its evolution in farmed poultry, the highly pathogenic virus has adapted to wild birds, meaning that it is circulating independently in wild populations, with some outbreaks occurring in remote areas that are distant from any poultry farms.
While the health risk to humans from bird flu may be low, it cannot be ignored. Highly pathogenic avian influenza has spread to mammals including otters, foxes, seals, dolphins, sea lions, dogs, and bears. Worryingly, it has been found in a Spanish mink farm where it then was able to spread from one infected mink to another.
The U.S. Department of Agriculture has said that cow-to-cow transmission is a factor in the spread of bird flu in dairy herds. The ability for bird flu to move directly from one mammal to another is troubling as a pandemic could ensue if it could move directly from one human to another.
Scientists at Scripps Research reveal that a single mutation in the H5N1 virus that has recently infected U.S. dairy cows could enhance the virus’ ability to attach to human cells, potentially increasing the risk of passing from person to person.
A 2023 joint statement from the World Health Organization, the FAO, and WOAH stated that, while avian influenza viruses normally spread among birds, “the increasing number of H5N1 avian influenza detections among mammals—which are biologically closer to humans than birds are—raises concern that the virus might adapt to infect humans more easily.”
Some mammals may also act as mixing vessels, leading to the emergence of new viruses that could be more harmful.
Pigs can be infected by avian and human influenza viruses as well as swine influenza viruses. Pigs can act as mixing vessels in which these viruses can reassort (i.e. swap genes) and new viruses that are a mix of pig, bird, and human viruses can emerge. The U.S. CDC explains that if the resulting new virus infects humans and can spread easily from person to person, a flu pandemic can occur.
Governments worldwide appear to have no strategy for how to end these regular bird flu outbreaks other than to hope they will eventually die down. There is no sign of this happening. Without an exit strategy we are likely to face repeated, devastating outbreaks of bird flu for years to come. We need an action plan to restructure the poultry and pig sectors to reduce their capacity for generating highly pathogenic diseases.
We need to:
In light of pigs’ capacity for acting as mixing vessels for human, avian, and swine influenza viruses, the pig sector too needs to be restructured to make it less vulnerable to the transmission and amplification of influenza viruses. As with poultry, this would involve reducing stocking densities, smaller group sizes, and avoiding concentrating large numbers of farms in a particular area.
As we reflect on the wonder of migratory birds, and the spotlight focuses on how our cities and communities can be made more bird-friendly, we must also consider how our food system is posing a threat to their very existence. Failure to rethink industrial farming leaves us vulnerable, with the continued devastation of wild birds and poultry, and perhaps even a human pandemic.
Chickens are smart, emotional animals; they deserve our respect.
My wife Janet and I started keeping chickens 14 years ago; we currently have four. Since we eat eggs, we figured we should take some responsibility for how those eggs come to us (I went vegetarian at age 20 once I realized the cruelty and suffering involved in producing the hamburgers I devoured). We wanted to see whether we could obtain eggs ethically and in a way that gave us more connection with our food. And, as bird lovers, we wanted to get to know some hens.
Lately, with egg prices soaring, there’s widespread interest in keeping chickens as a way of saving money. That was not our purpose, and raising hens hasn’t lowered our food bills—though they do give us plenty of lovely eggs. We invested in a secure chicken house and a covered run big enough to give our girls space to scratch and dust-bathe when it’s raining (on most days, we let them roam everywhere in our backyard except the vegetable garden, which they would happily destroy if they could). We feed them the best organic chicken feed. And we take them to the vet if required (one of our sweetest hens ever, Silvie, needed a hernia operation, a significant expense; that happened a year ago, and she’s fine now). We haven’t tried to calculate how much each egg costs us, but it’s more than a pittance.
There’s both good and sad to report from our years of living with hens. But we’re still at it and still learning.
One of the biggest payoffs of our hen hobby is the experience of living with alien creatures. Chickens aren’t much like dogs or cats. Birds have brains that are organized differently from mammalian brains, and birds see colors we can’t register. Chickens communicate vocally with about 25 different calls, screams, whines, cackles, purrs, and clucks. Janet and I spend a lot of time trying to understand what our hens are thinking and feeling, and we’ve learned a little about what motivates them.
Food is certainly at or near the top of the list. Chickens display extraordinary enthusiasm for food and are vigorously competitive whenever any treat is on offer. Their motto: Eat fast and ask questions later.
Reproduction sometimes takes top priority in the hen brain. We don’t keep roosters, since we live within city limits and an ordinance forbids them. Nevertheless, we have outlaw neighbors with roosters, and we are reminded daily that the male of the Gallus gallus domesticus species can indeed make a lot of noise. Roosters are required for fertile eggs, but in the absence of males, hens lay anyway. Some of our hens go broody occasionally, spending a couple of weeks sitting in their nest trying to incubate eggs that aren’t there, because we’ve collected them and put them in our refrigerator. Broody hens need special care, as they tend not to eat enough to keep themselves healthy. The hens often squat for us, as they would for a rooster wishing to copulate; when they do, we give them a backrub to partially fulfill their instinctive need—and to take advantage of a receptive moment when we can pet them or pick them up.
In 14 years, we have gotten to know 10 hens and can recall each one (Janet has painted individual portraits of most of them). We’ve witnessed sad deaths, but also beautiful lives.
Curiosity may be proverbially associated with cats, but we’ve found that chickens are perpetually inquisitive. They spend a large portion of each day exploring every corner of our yard, scratching in the dirt and digging holes. What’s down there? Who knows what might turn up?
Cleanliness requires effort. Sometimes chickens and other birds roll around in the dust as a way of discouraging mites and other pests (spa day!); afterward they shake their feathers in satisfaction. Feather maintenance is always a priority, and time must be devoted daily to preening. The versatile and sensitive beak must be cleaned occasionally by carefully wiping it on a hard surface (or our pants). Chickens and humans have very different ideas about cleanliness, but hens do care about it in their own way.
Affection might not be the strongest chicken motivator, but it certainly deserves to be listed. At first, we thought our chickens’ seeming enjoyment of human cuddles was merely a clever way of begging for more food treats. But long-term observation has shown us that some hens are just as affectionate as any dog or cat, and that food is not a strategic goal of cuddles. One of our hens, Lulu (more about her below) demands at least one cuddling session every day, and will sit in your lap for half an hour or more, soaking up love and offering all the hugs she can give, considering that she has wings rather than arms. Silvie is a cuddler too, but less demanding in that regard than Lulu. The hens’ affection for one another is a little more complicated, as we’re about to see.

Chickens are highly social creatures and instinctively establish a pecking order: One hen occasionally pecks others on the back of the head (often when everyone is eating) to show her dominance.
Lulu is at the top of the social ladder, and she’s a big, loud, confident hen. Friends have asked us whether chickens have individual personalities; the best answer is an introduction to Lulu. She is bossy around the other hens and demanding toward us. If she wants treats or cuddles, she lets us know by screaming—sometimes for minutes at a time—and, unfortunately, she’s as loud as any rooster. Being the top hen comes with perks, but duties as well. It’s up to Lulu to keep social order, watch for danger, and manage relations with the humans.
Stella and Sparrow—of rare designer breeds, while Lulu and Silvie are Orpingtons—are smaller, lower in the order, and relatively quieter and more skittish. Whenever Lulu is close by, they must be wary of a peck. But they’re not constantly bullied and seem to be happy, well-adjusted hens. They know the order and get their needs met within it. Sparrow is a cute comedian, always evoking chuckles from us humans. Stella is a self-reliant, industrious, elegant loner; she’s the smallest of our hens and has a scratchy voice but lays big pastel green eggs.
Some of our clearest insights into chicken social behavior come at dusk, as the hens enter their house and choose a spot on the perch. Who gets to sleep where, and next to whom? The lineup is different every night, and each night there are several tense minutes of jockeying. Sparrow seems to love snuggling up against big, fluffy Lulu, despite the prospect of a peck. Stella likes ascending the henhouse ladder last, and, though low in the hierarchy, usually gets her choice of sleeping spot. Always-agreeable Silvie (our vet called her “a very personable chicken”) just takes whatever space is available.

I’ve been astounded to learn the degree to which chicken evolution has been hijacked by humans. Genes matter, and for thousands of years people have been wittingly or unwittingly selecting chickens for humanly desirable traits.
Often, chickens pay a price. Humans want eggs; so, they breed hens that lay up to 300 of them a year—an astonishing feat. Laying an egg is no small matter. It literally takes a lot out of you. While wild relatives of the domestic chicken can live 20 years, most commercial hens live short lives, often (when they’re not killed for meat) perishing after 2 to 5 years. And while they’re pumping out those eggs, they can easily suffer from nutritional deficiencies and bone problems.
People have also bred chickens for size, feather and egg color, and behavior (I’ll refrain from discussing the commercial chicken meat industry, which has its own breeding priorities). Indeed, breeding has created more extreme varieties of chicken than of any other animal species except Canis lupus familiaris (dog). All our most affectionate hens have been Orpingtons of one sort or another: no accident, as most Orpingtons tend to be friendly.
Is it right for one species to interfere so much with the evolution of another? Not many humans seem interested in entertaining the question. One could conclude that chickens have benefitted from their relationship with people: Gallus gallus is by far the most numerous bird species (there are nearly 30 billion of them). So, humans have contributed to chickens’ evolutionary success. But that success depends entirely on chickens’ continued utility to a capricious ape whose overall activities are wrecking the biosphere. My advice: If you love feathered creatures, keeping chickens can teach you a lot about them, but you’ll do far more for this broad class of animals by creating or restoring habitat for wild birds.
In 14 years, we have gotten to know 10 hens and can recall each one (Janet has painted individual portraits of most of them). We’ve witnessed sad deaths, but also beautiful lives. Chickens are smart, emotional animals. They can decimate local insect populations, but they are resilient and courageous. They deserve our respect.
Oh, did I mention the poop? There’s lots of it. Everywhere. Every day. It’s good for the compost pile and the garden.
