This week, we explore the underground world with Robert MacFarlane of Cambridge University in England. Robert is the best-selling author of Landmarks and The Old Ways, and was awarded the EM Forster Prize for Literature by the American Academy of Arts and Letters. His latest book, UNDERLAND, is an "epic exploration of the Earth's underworlds as they exist in myth, literature, memory, and the land itself." The book also details the three major things that humans do with or in the underground world. You'll have to listen to the interview (or read the book!) to find out what they are.

Katy and Robert discuss fascinating yet obscure concepts like deep-time, and how instead of making our lives seem insignificant, this concept can inspire us to live every second more fully.

Robert also points out how important it is to keep cognizant of our ignorance, and never stop exploring and learning, and how spending so much time underground has taught him how much he loves the light and the living. Listen all the way to the end to find out the very scariest underground experience MacFarlane ever had.

**We will be giving away two copies of this book this month (open worldwide). Stay tuned for our #bookgiveaway post later this week.**
