Leather: Animals Abused And Killed for Their Skins

Every year, the global leather industry slaughters more than a billion animals and tans their skins and hides.1 Many of these animals endure all the horrors of factory farming—including extreme crowding and confinement, deprivation, and unanesthetized castration, branding, and tail-docking—as well as cruel treatment during transport and slaughter.

Everything but the Moo

The multibillion-dollar meat industry profits from more than just animals’ flesh. The coproducts of meat consumption include fat and blood that are used in livestock feed, tires, explosives, paints, and cosmetics; organs that are used in pet food; and heart valves that are used in medicine.2,3 The skin of the animal is often considered to be a significant economic co-product of the meatpacking industry.4

When the milk production of cows in the dairy industry declines, their skin is made into leather. The hides of their calves, who are frequently raised for veal, are made into high-priced calfskin. The economic success of slaughterhouses and dairy farms is directly linked to the sale of leather goods.

The Whole Ark

Most leather produced and sold in the U.S. is made from the skins of cattle and calves, but leather is also made from sheep, lambs, goats, and pigs. Other species are hunted and killed specifically for their skins, including zebras, bison, kangaroos, elephants, crocodiles, alligators, ostriches, lizards, and snakes.

Other “exotic” animals, such as alligators and crocodiles, are factory-farmed for their skins and meat. The young reptiles are often kept in tanks above ground, while bigger animals live in pools half-sunken into concrete slabs.5  According to Florida’s regulations, it is legal to put as many as 350 6-foot alligators into a space the size of a typical family home.6 The industry is so large and unregulated in that state that alligators and eggs are often poached for high prices.7 One Georgia farmer had 10,000 alligators living in four buildings, where, according to the Los Angeles Times, “[h]undreds and hundreds of alligators fill every inch of [each] room.”8

Dr. Clifford Warwick, a reptile biologist, says that such confinement can cause injuries and stress. “[Alligators’ and crocodiles’] biology and behaviour do not lend themselves to a captive life,” he says. “To a casual observer—and that often includes the people who run crocodile farms who are not usually scientifically qualified—the animals may seem peaceful and relaxed. But an animal behaviourist can see that they are stressed.”9

Although alligators can live up to 60 years, farmed alligators are usually butchered before the age of 2, as soon as they reach 4 to 6 feet in length.10,11 Alligators on farms may be beaten to death with mallets and axes, sometimes remaining conscious and in agony for hours after they’re skinned.12 On alligator and crocodile farms in Texas and Africa, PETA eyewitnesses saw alligators packed in dank pools and crocodiles crowded in barren concrete pits for months or even years before finally being slaughtered for their skins. An investigation into crocodile farms in Vietnam revealed that animals were skinned alive, and a biologist who viewed video footage of the slaughter concluded that “there was no probability the animals died instantly, and that they likely remained conscious and sensitive to stress and pain for up to two hours after the process.”13 For more on the appalling conditions in which these animals are raised and/or killed for “luxury” bags, belts, and watchbands, visit PETA.org.

Kangaroos are slaughtered by the millions every year, and their skins are often used for soccer shoes.14 Although the Australian government requires that hunters shoot the animals, orphaned joeys and wounded adults are, according to the government, to be decapitated or hit sharply on the head “to destroy the brain.”15 After learning about these cruel killing methods, soccer star David Beckham switched to shoes made from synthetic materials in 2006, and Adidas stopped using kangaroo skin for most of its shoes in 2012.16 In 2023, both Nike and Puma announced they would stop using kangaroo skins in their products, including soccer shoes.17

Snakes may be nailed to trees and skinned from one end to the other. In many cases, they’re still alive as they’re skinned.18 A PETA Asia investigation into a farm in Vietnam that supplies snakeskin for use in the global leather industry revealed horrific cruelty to snakes, including sealing their mouths and anuses with rubber bands and then inflating them to death with an air compressor, crushing their heart and causing severe pain. PETA Asia’s footage shows a snake’s tail moving during the lethal inflation, indicating that the pythons may still be alive as workers tear their skin off and disembowel them. The investigator did not see anyone checking vital signs before beginning the butchery. The snakes were held in cramped, dirty wire cages without water, food, or any enrichment. After learning that many of them had mites, a PETA Asia investigator asked about veterinary care, and a worker replied, “What’s the point [of treating the snakes]? We skin them anyway.” For more on this investigation, please visit PETA.org.

 The skins of unborn calves and lambs—some purposely aborted, others from slaughtered pregnant cows and ewes—are considered a “luxury.”19

The Western Cape of South Africa is home to the largest ostrich slaughter companies in the world, which supply “luxury” ostrich skins to Hermès, Prada, and other major fashion houses. PETA eyewitnesses saw young birds tightly packed into open-topped vehicles for the terrifying journey to slaughterhouses, where workers forcibly restrained each bird, electrically stunned them, and then cut their throats. Moments later, the feathers were torn off the birds’ bodies, and they were skinned and dismembered. For more about this investigation, please visit PETA.org.

Shearling, contrary to many consumers’ misconceptions, is not sheared wool—the term refers to a yearling sheep who has been shorn just once. A shearling garment is made from the skin of a sheep or lamb who is shorn shortly before slaughter. The skin is tanned with the wool still on it.

Tannery Toxins

Although leather makers like to tout their products as “biodegradable” and “eco-friendly,” the process of tanning actually stops the leather from biodegrading by stabilizing the collagen or protein fibers.

Until the late 1800s, animal skin was air- or salt-dried and tanned with vegetable tannins or oil, but today, animal skin is turned into finished leather with a variety of much more dangerous substances, including formaldehyde, coal-tar derivatives, mineral salts, and various oils, dyes, and finishes, some of which are cyanide-based.

Most leather produced in the U.S. and around the world is chrome-tanned. The Environmental Protection Agency considers all wastes containing chromium to be hazardous. In addition to the toxic substances mentioned above, tannery effluent also contains large amounts of other pollutants, such as protein, hair, salt, lime sludge, sulfides, and acids. A chrome-tanning facility wastes nearly 15,000 gallons of water and produces up to 2,200 pounds of “solid waste” (e.g., hair, flesh, and trimmings) for every ton of hides that it processes.20

Among the disastrous consequences of this noxious waste is the threat to human health from the highly elevated levels of lead, cyanide, and formaldehyde in the groundwater near tanneries. In Bangladesh, which exports leather goods to the United States, chemical exposure and equipment accidents pose such a great hazard that workers (many of them children) aren’t expected to live beyond age 50.21 The Centers for Disease Control and Prevention found that the incidence of leukemia among residents in an area surrounding a tannery in Kentucky was five times the national average.22 Arsenic, a common tannery chemical, has long been associated with lung cancer in workers who are exposed to it on a regular basis. Several studies have established links between sinus and lung cancers and the chromium used in tanning.23Studies of leather-tannery workers in Italy and Sweden found cancer risks “between 20% and 50% above [those] expected.”24

Raising animals for food and leather creates waste and pollution. Huge amounts of fossil fuels are consumed in livestock production: It takes about 35 calories of fossil fuel to make one calorie of beef and 68 calories of fossil fuel to make one calorie of pork.25 Researchers at the University of Chicago found that the typical American diet (nearly 30 percent of which comes from animal sources) generates the equivalent of nearly 3,300 pounds more carbon dioxide per person per year than a vegan diet with the same number of calories.26

Trees are cut down to create pastureland, vast quantities of water are used, and run-off from feedlots and dairy farms is a major source of water pollution. A California study found that a single cow on a dairy farm “emits 19.3 pounds of volatile organic compounds per year, making dairies the largest source of the smog-making gas, surpassing trucks and passenger cars.”27

According to the United Nations’ Food and Agriculture Organization, tanneries have largely shifted operations worldwide from developed to undeveloped nations, where labor is cheap and environmental regulations are lax.28

What You Can Do

Try vegan leather! It can be made from polyurethane, a resilient, flexible, and durable material that can be molded into a variety of goods, or from materials such as pineapple leaves, cork, apple peels, other fruit waste, or recycled plastic. Chlorenol (called “Hydrolite” by Avia and “Durabuck” by Nike) is a material that is perforated for breathability and is used in athletic and hiking shoes. It stretches around the foot with the same “give” as leather, provides good support, and is machine-washable. As a coproduct of the meat industry, cow leather is worse for the environment than any vegan leather.

Leather alternatives can be found just about anywhere you might shop. But some places, such as discount shoe and variety stores, offer larger selections. Designers such as Liz Claiborne, Capezio, Sam & Libby, Steve Madden, and Nike offer an array of nonleather handbags, wallets, and shoes.
