Shapeshifting
There are old folktales and legends of people who can become animals. Animals who can become people. And there’s a lesson for our own time in those shapeshifting stories — a recognition that the membrane between what's human and more-than-human is razor thin.
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.

How To Be An Ethical Traveler
Before the pandemic upended all world travel, we aired a show about what it means to be an ethical traveler. Between masks and vaccinations, COVID-19 has added even more to the ethical baggage we carry with us when we travel. But part of recovering from the pandemic involves getting back out there and seeing the world.
So before you take your next trip abroad, we thought we would revisit some thoughts and advice in that episode. Safe journeys.
This show was produced in partnership with AFAR Magazine, whose May/June 2019 issue on ethical traveling inspired this episode.

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?
