Contrast when war or conflicts take place the animals are left on their own. The problem of zoo animals escaping would never be a problem if the animals could be free in their natural habitat.
In animals natural habitat, there ability to roam endlessly and to anywhere they want, comes naturally to them. The desire to walk around, socialize with other animals, and be free show the needs animals demand to stay mentally, physically, and emotionally stable. Take away these mobilities and the animal starts to act in unusual behaviors. As stated by Corrine Henn, " When we capture animals from the wild and put them in zoos, these animals become commodities. They are stripped of their ability to display natural behaviors and lead a stilted existence filled with stress and boredom" (" The Shocking Truth"). Over long periods of time, animals start to develop symptoms which do not compare with symptoms from their relatives in the wild. The symptoms of a zoo animal happens so frequently, the name of zoochosis, describes their behaviors. "When a captive animal is not capable of modifying or controlling its environment, animals begin to cope by exhibiting stereotypic behavior" (Henn, " No, That Tiger"). When the animals pace back and forth, bite their cell bars, sway from side to side, regurgitate their food to play with it, or over groom shows their discomfort and lack of desire to be in their situation. Many people believe the animals perform some of these actions for entertainment while the animals just want someone to let them go. .
Over periods of time, the effects of living in neglected conditions take tolls on the animals bodies and can cause depression and other mental problems. With visitors seeing sad and depressed animals as not being attractive, zoos give their animals antidepressants and psychoactive drugs to help them seem more happy and alive.
