The zoo is a place for animals to study the behavior of human beings.
The zoo is a place of confinement, not conservation.
A zoo is a good place to make a spectacle of yourself, as long as you don't make a spectacle of the animals.
Zoo animals are ambassadors for their cousins in the wild.
The only way to keep a wild animal in a zoo is to keep it in a zoo.
Zoos are becoming facsimiles - or perhaps caricatures - of how animals once were in their natural habitat.
I meant what I said, and I said what I meant. An elephant's faithful one-hundred percent!
The greatness of a nation and its moral progress can be judged by the way its animals are treated.
Until one has loved an animal, a part of one's soul remains unawakened.
If a zoo is a jail, then what is a city?
Animals are such agreeable friends―they ask no questions; they pass no criticisms.
The question is not, 'Can they reason?' nor, 'Can they talk?' but rather, 'Can they suffer?'
The more you learn about animals, the more you realize how amazing they are.
A zoo is a cultural institution, like a museum or a library.
I believe that zoos are part of the problem and not part of the solution.
In the end, we will conserve only what we love; we will love only what we understand and we will understand only what we are taught.
