I mean, it's John Green. If you know this guy (or watch him on Youtube, I especially enjoy Vlog Brothers), then you know what's in store: personal stories that are a little bit funny, a little bit sad, and very moving and heartfelt (I keep using that word in my reviews). See the world of humanity through John Green's eyes as a father, as someone who suffers from depression, as a very smart man, as a famous writer of teen fiction (but this is non-fiction, this is him talking about the world, the human race, and then giving these bits of humanity a 1-5 star rating).

I give John Green's The Anthropocene Reviewed as an audio book... 3 and a 1/2 stars.
