Veganism increased significantly in popularity in the 2000s, in part for reasons of human health, and in part out of concern for animals or the environment.[1]
Vegans can be split broadly into three groups. Dietary vegans exclude animal products from their diets, often for health reasons, but may continue to wear clothes or use toiletries that contain them. Ethical vegans are concerned with animal rights, rejecting the commodification of animals entirely, and refusing to eat or use them in any way. Environmental vegans argue that a wholly plant-based diet is the only environmentally sustainable way to feed the expanding human species; Paul Watson, president of the Sea Shepherd Conservation Society, writes that the society's ships are vegan because its crews are marine conservationists, not because they are animal rights advocates.[2]
