Ms. Shelbourne's numerous stories are extremely thought provoking and her comments on how zoos need to change so that they really educate people on the behavior and emotional needs of their residents are important for future generations of captive animals who simply cannot be released into the wild. The questions with which she ends her book, including "What is being done to conserve the habitat of the animal concerned? (p. 125)" need to taken to heart when people are making decisions about "donating your well-earned cash to a wildlife project." If the habitat of a species is disappearing as individuals of that species live in captivity a donation won't really do much for their future. Likewise, it's essential to know how the local human community can also be helped so that they welcome the animals back at some future time.
I highly recommend both books to a wide audience. They raise numerous important and challenging questions about the nature of human-animal relationships (anthrozoology) and are extremely inspirational. Each also shows how we can easily rescue, help, and heal other animals and how they can in turn rescue, help, and heal us, a topic about which I've recently written.
