President Trump’s proposed 2,000-mile long, 30-foot high border wall would obstruct more than just a pretty landscape. It could bring an end to the species that live in the lush coastal grasslands, searing hot deserts, and staggering mountain peaks in the path of the wall. In this episode of Trump on Earth, we team up with a fellow environmental podcast, Generation Anthropocene, as Stanford student Maddy Belin talks with Penn State University Professor Jesse Lasky for their episode entitled “Oh Right, the Animals.”

About one-third of the country is federally-owned. That means it belongs to all of us -- the public. But that also gives the President a lot of power over these places. Today on Trump on Earth, we’re taking a closer look at what’s at stake, and what we can expect next for our public lands.
