Captivity Drives Animals Insane 1

Zoos limit the natural behavior patterns of animals, including migration and in many cases, flight. Animals who would shun contact with humans in nature have no way to escape routine contact with them. Many develop neurotic and self-harming behavior (called “zoochosis”) that are rarely, if ever, observed in the wild. Some birds pluck out their own feathers. Elephants often sway back and forth. Tigers pace nonstop, and polar bears are often seen swimming endless figure-eights. Aquatic animals suffer, too and may repeatedly raise their heads above water or turn on one side and rub along the floor of the tank.
