Many vegans follow this lifestyle "for ethical reasons". These reasons are usually related to avoiding animal suffering and exploitation. Moreover, some vegans might see the concern for the environment as a matter of ethics. Is there any other reason why people decide to go vegan?
Clarification: The question "Reasons for being vegetarian or vegan other than ethical reasons?" addresses non-ethical reasons. Here I ask for ethical reasons apart from "avoiding animal and environmental explotation", if any. If there are not other reasons, then the answer might simply be "there are not other reasons".
