Cannibalism is the act of consuming the flesh of one's own species. It has been observed in various cultures and species, including humans and animals. In humans, it can occur for various reasons, such as survival, ritualistic practices, or psychological disorders. Historically, some tribes, like the Fore people of Papua New Guinea, practiced cannibalism as part of their cultural rituals. In modern times, it is often associated with criminal behavior and is illegal in most countries. Cannibalism raises ethical and moral questions, making it a complex topic in anthropology and sociology.
