In this week\u2019s episode, host Margaret Walls talks with Casey Wichman, an assistant professor at the Georgia Institute of Technology and university fellow at Resources for the Future, about the influence of social media on the popularity of national parks. Wichman estimates in a recent study that more exposure of a national park on social media increases visits to that park. He discusses people\u2019s relationships with national parks in a digital age; the effects of increased visitation on persistent issues in national parks, such as overcrowding and underfunding; and the potential boost in revenue that social media exposure can provide to national parks.\n\nReferences and recommendations:\n\n\u201cSocial Media Influences National Park Visitation\u201d by Casey Wichman; https://www.rff.org/publications/journal-articles/social-media-influences-national-park-visitation/\n\n\u201cA New Study Finds Crowds at National Parks May Be Due to Social Media\u201d by Wes Siler in \u201cOutside\u201d magazine; https://www.outsideonline.com/outdoor-adventure/hiking-and-backpacking/national-parks-social-media/\n\n\u201cDo National Monuments Help or Hinder Local Economies?\u201d episode of the \u201cResources Radio\u201d podcast; https://www.resources.org/resources-radio/do-national-monuments-help-or-hinder-local-economies-margaret-walls/\n\n\u201cOutside\u201d magazine; https://www.outsideonline.com/\n\n\u201cMountain Gazette\u201d magazine; https://mountaingazette.com/\n\n\u201cThe Wolf, the Duck, and the Mouse\u201d by Mac Barnett and Jon Klassen; https://www.penguinrandomhouse.com/books/559535/the-wolf-the-duck-and-the-mouse-by-mac-barnett-illustrated-by-jon-klassen/
