When Mountains Are Gods
If you look at a mountain, you might see a skiing destination, a climbing challenge, or even a source of timber to be logged or ore to be mined. But there was a time when mountains were sacred. In some places, they still are. What changes when you think of a mountain not as a giant accumulation of natural resources, but as a living being?
Today’s show is part of our project on kinship with the more-than-human world — produced in collaboration with the Center for Humans and Nature, and with support from the Kalliopeia Foundation. You’ll find more information about the project at ttbook.org/kinship and humansandnature.org.

How Africans Are Building The Cities Of The Future
Africans are moving into cities in unprecedented numbers. Lagos, Nigeria, is growing by 77 people an hour — it's on track to become a city of 100 million. In 30 years, the continent is projected to have 14 mega-cities of more than 10 million people. It's perhaps the largest urban migration in history.
These cities are not like Dubai, or Singapore, or Los Angeles. They’re uniquely African cities, and they’re forcing all of us to reconsider what makes a city modern. And how and why cities thrive.
To find out what's going on, we go to Addis Ababa, Ethiopia, to talk with entrepreneurs, writers, scholars and artists. In this hour, produced in partnership with the Consortium of Humanities Centers and Institutes (CHCI) — a global consortium of 270 humanities centers and institutes — we learn how the continent where the human species was born is building the cities of the future.

Eye-To-Eye Animal Encounters
There's a certain a kind of visual encounter that can be life changing: A cross-species gaze. The experience of looking directly into the eyes of an animal in the wild, and seeing it look back. It happens more often than you’d think and it can be so profound, there’s a name for it: eye-to-eye epiphany. So what happens when someone with feathers or fur and claws looks back? How does it change people, and what can it teach us?
Human identity cannot be separated from our nonhuman kin. From forest ecology to the human microbiome, emerging research suggests that being human is a complicated journey made possible only by the good graces of our many companions. In partnership with the Center for Humans and Nature and with support from the Kalliopeia Foundation, To The Best Of Our Knowledge is exploring this theme of "kinship" in a special radio series.
