"The Overstory may present an even greater challenge to the sense of exceptionalism we humans carry around inside us. It’s the story of immense, long-lived creatures whom many people think of as little more than simple automatons, but who, in fact, communicate and synchronize with each other both over the air and through complex underground networks, who trade with and protect and sustain their own and other species. It’s about immensely social beings with memory and agency who migrate and transform the soil and regulate the weather and create a breathable atmosphere. As the great Le Guin put it, the word for world is forest."
