This picture reminds me why I'm always a little sad when I go to the zoo. It's wonderful to see all the beautiful animals, the colors and the smells, how it brings a little bit of the world here to us. But then I see an animal like this, and start thinking about how they live in a box, instead of a jungle... This guy's sitting on concrete and leaning against plexiglas, when he should be swinging from tree to tree, miles away from the nearest human.
