"Carnism is the invisible belief system, or ideology, that conditions people to eat certain animals. Carnism is essentially the opposite of veganism; "carn" means "flesh" and "ism" denotes a belief system. Most people view eating animals as a given, rather than a choice; in meat-eating cultures around the world people typically don’t think about why they find the flesh of some animals disgusting and the flesh of other animals appetizing, or why they eat any animals at all. But when eating animals is not a necessity for survival, as is the case in much of the world today, it is a choice - and choices always stem from beliefs."
