Across the United States there are hundreds of millions of acres of public lands. Indeed, there are more than 500 million acres of federal lands managed by the U.S. Bureau of Land Management, the U.S. Forest Service, and the National Park Service, just to name the three largest land managers in federal government.

A majority of those lands, the 245 million acres managed by the BLM and the 193 million managed by the Forest Service, are managed for multiple use. Logging, mining, recreation, and even official wilderness. The National Park Service lands, of course, are primarily managed for conservation of natural resources and enjoyment by you, the visitors.

But the Trump administration has an eye on some of those lands for energy development and mining, whether that's oil and gas production or hard-rock mining. To better understand what's at stake under that strategy we're joined today by Dan Hartinger, the senior director of agency policy at the Wilderness Society.
