The Vegan Society defines veganism as, "A philosophy and way of living which seeks to exclude - as far as is possible and practicable - all forms of exploitation of, and cruelty to, animals for food, clothing or any other purpose; and by extension, promotes the development and use of animal-free alternatives for the benefit of animals, humans and the environment. In dietary terms it denotes the practice of dispensing with all products derived wholly or partly from animals."
Although most of us were raised to use animals in various forms, whether as food, by wearing their skins, making products from leather, wool and down; or by going to events like circuses, rodeos or zoos for entertainment, a sincere look at these practices shows us many faults in continuing to live that way.
Now more than ever we understand the abuse inherent in exploiting animals. Also now more than ever, there are guides to being vegan and a multitude of products, with more being developed every day, that we can employ to easily, healthily and happily go vegan.
Is veganism perfect? No. Nothing in this physical life is. But living a vegan lifestyle creates the least amount of harm done to animals, to our own health (particularly if we choose a whole food approach), and to the planet. Learn to go vegan here.
