Veganism is the practice of eliminating the use of non-human animal products. Ethical vegans reject the commodity status of animals and the use of animal products for any purpose, while dietary vegans or strict vegetarians eliminate them from their diet only. Another form, environmental veganism, rejects the use of animal products on the premise that the industrial practice is environmentally damaging and unsustainable.
The term "vegan" was coined in England in 1944 by Donald Watson, co-founder of the British Vegan Society, to mean "non-dairy vegetarian"; the society also opposed the use of eggs as food. It extended its definition in 1951 to mean "the doctrine that man should live without exploiting animals," and in 1960 H. Jay Dinshah started the American Vegan Society, linking veganism to the Jainist concept of ahimsa, the avoidance of violence against living things.
