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."
