Cannibalism is as old as the hills. It is the act or practice of humans eating the flesh or internal organs of other human beings. The expression cannibalism has been extended into zoology to mean one individual of a species consuming all or part of another individual of the same species as food, including sexual cannibalism. It has been both practiced and fiercely condemned in several wars, especially in Liberia and Congo. It was still practiced in Papua New Guinea as of 2012 for cultic reasons and in ritual and in war in various Melanesian tribes.
