It does seem from that article that the zoo isn't able to provide the changes in her enclosure that would benefit an elephant and unless I read it wrong, she's housed alone as their only elephant at that zoo. I really think that's awfully wrong as these are social creatures where all females live their entire lives within their matriarchial group. I don't support PETA but I do think that any zoo must put the animal's best interests above their own desire to exhibit that particular species.
