The Anthropocene Reviewed is the shared name for a podcast and 2021 nonfiction book by John Green. The podcast started in January 2018, with each episode featuring Green reviewing "different facets of the human-centered planet on a five-star scale". The name comes from the Anthropocene, the proposed geological epoch that includes significant human impact on the environment. Episodes typically contain Green reviewing two topics, accompanied by stories on how they have affected his life. These topics included intangible concepts like humanity's capacity for wonder, artificial products like Diet Dr. Pepper, natural species that have had their fates altered by human influence like the Canada goose, and phenomena that primarily influence humanity such as Halley's Comet.
