People who support them would argue that they preserve threatened animal species.... Then the arguments against zoos are mainly "the animals have no privacy"; "there isn't enough space for the animals"; "[insert species] needs [insert number] square MILES that they can't get in a zoo exhibit"; "the animals aren't meant for captive life, so they're miserable"; and "too many zoo animals are taken from the wild for life "in cages"". What are your feelings toward zoos? Support them? Oppose them? Think they're a 'necessary evil'? Think they're good for the most part, but have at least one fault that was mentioned above (or any others you can think of)? Or can you disprove every argument against them that was listed?
