Cannibalism has been practiced by various cultures throughout history, often in specific ritualistic or survival contexts. However, in contemporary times, there are no countries where cannibalism is a mainstream practice or widely accepted. Most nations have laws against cannibalism, and it is generally considered a taboo and a criminal act.
There have been isolated incidents or reports of cannibalism in certain contexts, such as extreme survival situations or criminal cases, but these do not reflect a cultural practice endorsed by the wider society. Some historical groups, such as certain tribes in Papua New Guinea and parts of the Amazon, engaged in cannibalistic practices, but these have largely been abandoned.
