Every year, the global leather industry slaughters more than a billion animals.  If you're wearing leather, you're wearing the skin of a horribly abused animal. Today leather we wear comes from animals as cows , pigs , kangaroos . The production of leather hurts animals, the environment, and the workers who manufacture it. Raising animals for food and leather requires huge amounts of feed, pastureland, water, and fossil fuels. Animals on factory farms produce 130 times as much excrement as the entire human population, without the benefit of waste treatment plants.

Although  some leathermakers  deceptively  tout their products as "eco-friendly," turning skin into leather also requires massive amounts of energy and dangerous chemicals, including mineral salts, formaldehyde, coal-tar derivatives, and various oils, dyes, and finishes, some of them cyanide-based. Tannery effluent contains large amounts of pollutants, such as salt, lime sludge, sulfides, and acids. The process of tanning stabilizes the collagen or protein fibers in skins so that they actually stop biodegrading—otherwise the leather would rot right off your feet.

 People who work in and live near tanneries suffer too. Many die from cancer possibly caused by exposure to toxic chemicals used to process and dye the leather. The Centers for Disease Control and Prevention found that the incidence of leukemia among residents in an area near one tannery in Kentucky was five times the U.S. average.

 Arsenic, a common tannery chemical, has long been associated with lung cancer in workers who are exposed to it on a regular basis.  Additionally, raising the animals whose skin eventually becomes leather requires vast quantities of water and wide tracts of pastureland, which must be cleared of trees.

How we all can help?

With so many stylish synthetics now available, there is no excuse for supporting animal abuse. The best thing that we can do to help animals killed for their skin is to boycott all leather products and urge everyone we know to do so as well.

After all Animals are not for us to eat , wear , experiment on or use for entertainment or abuse in any way.
