By definition, 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.
Veganism is the practice of abstaining from the use of animal products, especially in diet, and an associated philosophy that rejects treating animals like commodities.
An individual who follows this philosophy is a vegan.
