While these are some very beautiful photos of animals, I think most of them belong in the wilderness. They have simply not enough space to live in a zoo, for example the tiger shown in one of the photos has a habitat of round about 3000km in the wilderness.
If you are interested in helping animals, like the tiger, suffering from extinction due to hunting and rainforest conservation, you may have a look at my Vonation post. Helping was never this easy:
