What is the author's tone in My Life with the Chimpanzees by Jane Goodall?

The tone of My Life with The Chimpanzees is most appropriate for a pre-teen audience and that of a simplified autobiography. Its tone is mostly positive and attempts to inspire the reader to love animal life and protect it. While My Life with The Chimpanzees is primarily an autobiography, it also advances substantive views about how to treat animals but it maintains its softer tone throughout. The tone is only sad when things do not go well for Goodall, such as when she is divorced from Hugh or when her graduate students were captured. But these events are few and far between. Consequently, the book's tone is largely positive peppered only with bits of sorrow.
