"Keeping elephants in an area that experiences prolonged, cold winters means that the elephants must be kept indoors for a great deal of time. Some may not get outside for weeks. This can lead to problems with foot disease, joint disorders and obesity," also adds Doyle.
The bottom line is this: Some people don't frequent zoos because they don't believe animals should be in captivity at all. But if you do visit a facility, use your common sense. If the animals look miserable, and if you leave with a sense of sorrow in your stomach, then the zoo isn't right for you.
