In this episode of Across The Margin: The Podcast, host Michael Shields, with the help of author and National Park Service (NPS) authority Dr. Gil Lusk, celebrate the national treasure that is the United States’ National Park System. Dr. Lusk is a retired National Park Service employee with thirty-five years of experience. For his efforts, he was awarded the U.S. Department of Interior's two highest performance awards: the Meritorious Service and Distinguished Service awards, the latter presented by the Secretary of Interior and the President. Dr. Lusk’s book, National Parks: Our Living Treasure (A Time For Concern), recounts the origins and the rich history of the NPS, while also ushering readers into NPS’s current conflicted era, where an abundance of issues endanger the important mission and preservation goals of the NPS. In this episode, Michael and Dr. Lusk converse over what makes the National Parks and the National Park Service so special, break down the crucial concerns facing the National Park Service (particularly politically), and climatically, Dr. Lusk suggest a series of urgent changes that are needed to bring the NPS back to its prime and ensure the protection of one of America’s most wondrous treasures.
