Indeed. As shown by the dedication plaque, it is what is says on the tin. Animal Kingdom is about animals.
Conservation, Adventure, Exploration....these are *aspects* of animals (real, ancient or imaginary) that you could apply to individual attractions or stories you want to tell about particular animals, but it's projection, misdirection, indirection or whatever to then say that those are the aims of the park therefore more attractions based on adventure, but not necessarily animals, are fitting. Those associated aspects are being used to justify what they want to do, as if that's the main aim of the park, not the animals.
