Goodall writes in a way that serves equally for zoologists or school kids. She's clearly there as a narrator, but only enough to lend her good name to the animals and animal protection activists she honors. She sounds like a Dalai Lama of the global conservation movement, able to lift hearts by her presence. The stories themselves are gritty with grim detail on the fate of animals, and each featured case involves a near brush with total extinction. The activists resort to captive breeding, predator exclusion fences, even extermination of invasive species. Then they have to gain buy-in from the local people. They have to slowly work toward community agreements on ways of living that allow biodiversity, or maybe even stimulate it.
I think every public school system should use this as a textbook. The kids would get a world of insight and it would naturally ignite passion. The index is loaded with ways the classes could learn through engagement in making a difference.
