“The Anthropocene Reviewed” is neither book nor film nor album but deserves a review because in a real sense, this podcast is a book, an elegant, intelligent collection of essays wrought by a fine writer. Listening to the podcast, you can almost see John Green reading out the words, each episode immaculately conveyed. The conceit is that in each episode he rates, out of five, like a movie reviewer, a couple of aspects of humans in the Anthropocene Era in which humanity is remaking the planet Earth. Green intermingles the profound recollection underlying “Googling strangers” with an environmental reflection on lawn grass in “Kentucky Bluegrass” and quirkiness such as in “Piggly Wiggly.” Wise, humorous, and literary.
