In a world that seems so troubled, how do we hold on to hope? Addressing this urgent problem, naturalist Jane Goodall and Douglas Abrams engage in a thought-provoking dialogue on one of the most sought after and least understood elements of human nature: hope. Telling the story of how she became a messenger of hope, Goodall reflects on World War II, her years in Gombe, and her role as an advocate for environmental justice. Goodall also unpacks her "Four Reasons for Hope": The Amazing Human Intellect, The Resilience of Nature, The Power of Young People, and The Indomitable Human Spirit.
