Veganism is 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.”
*I have my doubts on whether one could call veganism a philosophy. I think veganism is a lifestyle, and sentientism the philosophy behind it. More on this soon.
