In 'The Anthropocene Reviewed,' author John Green explores our current geological age, the Anthropocene, where humans are the dominant force shaping the planet. He does this by reviewing different aspects of our world—from the mundane, like Diet Dr Pepper and the QWERTY keyboard, to the profound, like sunsets and the human capacity for wonder—on a five-star scale. Through these personal and often funny essays, Green examines the beautiful, heartbreaking, and deeply strange reality of living in a human-centered world. The book invites readers to look closely at the everyday marvels and contradictions of our shared existence.
