The Anthropocene is the current geologic age, in which humans have profoundly reshaped the planet and its biodiversity. In this remarkable symphony of essays adapted and expanded from his podcast, bestselling author John Green reviews different facets of the human-centered planet on a five-star scale—from the QWERTY keyboard and sunsets to Canada geese and Penguins of Madagascar. Funny, complex, and rich with detail, the reviews chart the contradictions of contemporary humanity. As a species, we are both far too powerful and not nearly powerful enough, a paradox that came into sharp focus as we faced a global pandemic that both separated us and bound us together.
