The Anthropocene Reviewed started out as a podcast, where bestselling author John Green tried to make sense of some of the contradictions of human life – how we can be so compassionate, and yet so cruel. So persistent, yet so quick to despair. Green says that above all, he wanted to understand the contradiction of human power; how we are too powerful in our ability to shape the climate and biodiversity, for example, and yet not powerful enough to save those we love from suffering.
