Captives are individuals who are held against their will, often in situations involving conflict, crime, or captivity. This term can apply to hostages taken during a kidnapping or prisoners of war during military conflicts. Captives may be held for various reasons, including ransom, political leverage, or coercion. In some cases, captives can also refer to animals kept in captivity, such as those in zoos or aquariums. These animals are often removed from their natural habitats for conservation, education, or entertainment purposes. The treatment and welfare of captives, whether human or animal, raise important ethical considerations.
