That they don't let animals roam in different cages == Animals in Zoos ( America, or anywhere to be fair, but I will use America as an example, just to prove my point that America is not perfect) can be beaten, and treated appallingly. One such example took place when an African elephant was transferred from the San Diego Zoo to the San Diego Wild Animal Park; her old caretakers reported seeing her chained to the ground, and beaten on the head with axe handles for two days. Some of the blows were described as "home run swings." Also, another Zookeeper in San Francisco was quoted as saying of Elephants, "You have to motivate them and the way you do that is by beating the hell out of them." This happened in San Diego, and San Francisco, of America. For details see the site listed below.
I believe that zoos use animals for there own need. 1 out of 10 people care about there pet and 1 out of 50 zoos care about the animals the way they should. Bad zoos use cement cages and don't let animals stand on their own feet. This causes them to be unable to fend for themselves. This problem is mostly seen in places like Ethiopia. Unfortunately I cannot find the doco I watched on Australia's ABC channel showing cruelty to bears in poorer countries zoos. Another mistake many zoos make is separating and isolating pack animals. They are called pack animals for a reason. When separated from their pride, pack, pod, flock or herd many animals will die. And in many zoos, not only do they isolate them but, put them in cages with concrete floors, and bars. How would you feel to suddenly be taken from your home where you ran free with your family and put in a cage with a cold, hard floor to be stared at by people day in and day out. Most only looking for less than 30 seconds before making some derogatory remark and walking off. This fact has been proved in a study, which was conducted in America. Most people don't care about the animals, they are just looking for another way to entertain themselves. We have brains for a reason, learn how to use it. *Certain contributions to this question have been moved to the discussion field during the editing process of this answer.
Some people think animals should be kept in the wild.
Some people view zoos as bad because they feel animals are detained. Some zoos are no trained properly to care for the animals they own. Zoos who provide proper medical care, proper diets, and proper living facilities are safe for the animals. Some zoos actually house many injured animals, and care for the ones who could never be returned to the wild.
the majority of zoos are bad for animals
Because zoos' temparature is not better for penguins.
Zoos that have bad minds. Get them out of the zoo!
yes. Killed them, taken there homes put them in Zoos and many bad things
Some zoos have goats but not all zoos.
Good things about zoos are that the zookeeper does research on the animal so, they can feed it, care for it and breeding it.
That depends on your opinion, but good zoos do provide opportunities for education and also they help endangered species grow back. Bad zoos, where they use the animals only for entertainment, are cruel and should be banned, but good zoos have their uses.
its every thing
It is a matter of ones opinion. Some think zoos are good and educational, while others think zoos are bad. I think it depends on the zoo in question. I've seen some with environmentally stimulating habitats and alert, inquisitive animals, and others with only the most basic requirements and bored, unmotivated animals. It's also a matter of opinion like you^ said.
At some Zoos they do.
