i think that they are both good and bad. this is because without the zoos extinct species in the wild would be extinct forever if it wasnt for the zoos. but thery are also a bad thing as the animals are put in tiny cages with barely any room to act normal, no space to hide from visitors and very little space. and also Elephants and other animals migrate for food and use the same path year after year and stop at the same watering hole. so as you can guess i think that they are bad really but in another sense i am all for them. another reason why they look so bad is because that most zoos are charity and so dont have a big budget to expand cages or make them big enough so its not their fault if its any bodys fault its the pochers because if they didnt kill the animals for little money we wouldnt have to build these cruel places.
