If you want to revel in the wonder of the natural world, while still asking tough questions about our place in that world, I'd like to tell you about a podcast you might enjoy.

It's called Outside In. Hosted by Sam Evans Brown, Outside In tackles a broad range of subjects, from the environmental movement's troubling links to the

eugenics movement, to the fraught history between hydropower development and indigenous rights in

Canada. Outside Inn tries to capture the joy that attracts so many of us to the outdoors in the

first place. The show has taken listeners under the ice of

frozen lakes, to peat bogs in the Arctic, and up close to patches of moss in your own backyard.

Outside Inn features deeply investigated stories and the deliberately goofy. They've staged debates over which is the best animal and the best fruit,

and they've tried to identify the fastest way a human could travel

before the internal combustion engine.

Outside In makes you think and makes you laugh.

You can find Outside In in your favorite podcast app and at outside in radio.org.

Leave it as it is, he said. You cannot improve on it.

Roosevelt went on to preserve 230 million acres of American land, which was unprecedented.

Today's guest is the author of a book called Leave It As It Is.
