You might not know it, but you are at war.

The eastern United States is home to two-thirds of the country’s population and two-thirds of the continental forested area. With forests come deer, geese, coyotes, beavers, squirrels. 

Jim Sterba, the author of Nature Wars, says Americans live in closer proximity to more wild animals, birds and trees in the eastern United States than anywhere else on the planet at any time in history.

Sterba says we are engaged "in battle" with those critters—a battle that has changed dramatically over the years with deforestation, urban sprawl, and the good intentions of conservation. Sterba sat down with Emily Rooney in the BPR studios, where they also heard from listeners who shared some of their close encounters of the furry kind.
