When you're based in The Beaver State, once in a while you'll get around to talking about beavers. And we do, with Ben Goldfarb.
He wrote a book called Eager: The Surprising, Secret Life of Beavers and Why They Matter.
That last phrase is the key; beavers were instrumental in creating the landscape that early white visitors found when they arrived in the region.
And those visitors promptly set about trapping the beavers, thus changing the landscape. Can it look like that again?
We explore that question and more with the book's author.
