Hunting involves legally or illegally killing animals by chasing them and has specialized techniques. Historically, animals were hunted for food, trade, or other resources, while today hunting is often pursued for entertainment, skins, and body parts. While hunters argue it balances populations and funds conservation, critics note the unnecessary suffering of animals given alternative food sources and the threat to endangered species. Mexico's state of Chiapas and many African nations have popular and profitable hunting industries, though it is illegal in some countries. Animal rights groups protest the practice but have faced societal resistance to protecting hunted animals.
