The global leather industry is responsible for torturing and murdering animals as well as exposing our environment to hazardous toxins in order to make its final product. Most of the leather in the U.S. comes from India, where cows are marched hundreds of miles in the heat without food or water. They have their tails broken and chili peppers and tobacco rubbed into their eyes in order to force them to get back up after they collapse. In the slaughterhouse, their throats are cut and they’re skinned, often while they’re still alive—all this just to make a shoe or a belt.

Leather—The Meat and Dairy Industries’ BFF

The multibillion-dollar meat industry profits from more than just animals’ flesh. The byproducts of meat consumption include organs that are used in pet food, heart valves that are used in the pharmaceutical industry, and fats and blood that are used in livestock feed, tires, explosives, paints, and cosmetics.1,2 The skin of the animal, however, represents “the most economically important byproduct of the meat packing industry.”3

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.

Torture and Slaughter

Most leather produced and sold in the U.S. is made from the skin of cows and calves, but leather is also made from horses, sheep, lambs, goats, and pigs who are slaughtered for meat. Other species are hunted and killed specifically for their skins, including zebras, bison, water buffalo, boars, kangaroos, elephants, eels, sharks, dolphins, seals, walruses, frogs, turtles, crocodiles, lizards, and snakes.

Other “exotic” animals, such as alligators, are factory-farmed for their skin and flesh. Young alligators are often kept in tanks above ground, while larger animals live in pools half-sunken into concrete slabs.4 According to Florida’s regulations, as many as 350 6-foot alligators can legally inhabit a space the size of a typical family home.5

Humane treatment isn’t a priority for those who poach and hunt animals to obtain their skin or those who transform skin into leather. Alligators on farms may be beaten to death with hammers and axes, sometimes remaining conscious and in agony for up to two hours after they’re skinned.6

Snakes and lizards may be skinned alive because of the belief that live flaying makes leather more supple. Kid goats may be boiled alive to make gloves, and the skin of unborn calves and lambs—some purposely aborted, others from slaughtered pregnant cows and ewes, respectively—are considered especially “luxurious.” Shearling, contrary to many consumers’ misconceptions, is not sheared wool. The term refers to a yearling sheep who has been shorn once. A shearling garment is made from the skin of a sheep or lamb who was shorn shortly before slaughter. The skin is tanned with the wool still on it.

Animals who are used to produce leather in other countries often suffer horribly as well. A PETA investigation into cattle slaughter in India—where many people mistakenly believe that cows are treated well because they’re revered by some Indians—revealed that old cows are sold at auction and then marched long distances to illegal transport trucks. Often sick and injured from the grueling march, as many as 50 cattle are crammed into trucks designed to hold no more than a dozen animals. They’re then driven over rutted roads—all the while goring and trampling each other—to ancient slaughterhouses where all four feet are bound together and their throats are slit.

Leather’s Toll on Human Health and the Environment  

Although leathermakers like to tout their products as “biodegradable” and “eco-friendly,” the process of tanning stabilizes the collagen or protein fibers so that they actually stop biodegrading. Animal skin is turned into finished leather with a variety dangerous substances, including mineral salts, formaldehyde, coal-tar derivatives, 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. All wastes containing chromium are considered hazardous by the Environmental Protection Agency. 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.7

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. The Centers for Disease Control and Prevention found that the incidence of leukemia among residents in an area surrounding one tannery in Kentucky was five times higher than the national average.8 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 cancer and the chromium used in tanning.9

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.10

Raising animals whose skins eventually become leather creates waste and pollution. Researchers at the University of Chicago found that the typical American diet (of which nearly 30 percent 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.11 Trees are cut down to create pastureland, vast quantities of water are used, and feedlot and dairy-farm runoff is a major source of water pollution.

3 Things You Didn’t Know About Leather 

  1. Hundreds of thousands of dog and cat skins are traded in Europe each year (with an estimated 2 million dogs and cats killed in China to meet the demand). Many of the items made from them are bought by unsuspecting consumers because they are often deliberately mislabeled and don’t accurately indicate the origin of the skin.12 In France, more than 20,000 cats are stolen for the skins trade annually.13 During a police raid on a tannery in Deux-Sèvres, France, 1,500 skins, used to make baby shoes, were seized.14 When you buy leather products, you may unknowingly be purchasing leather from dog and cat tanneries.
  2. Kangaroos are slaughtered by the millions every year. Their skins are considered prime material for soccer shoes.15,16
  3. Alligators used for their skin often live in horribly inhumane conditions for the duration of their short lives until they’re slaughtered. One Georgia farmer had 10,000 alligators living in four buildings, where “[h]undreds and hundreds of alligators fill every inch of [each] room,” according to the Los Angeles Times.17

What You Can Do

You can help animals used for their skin by not buying products made from leather or any other type of animal skin. It’s easy to find vegan leather shoes, belts, and jackets. You can also take action for animals by sharing our “Where Leather Is Born” video with everyone you know!
