Michigan Advance’s Susan J. Demas writes, “We’ve rethought a lot of our ideas about conservation since Yellowstone was established as the nation’s first national park in 1872. Roads were built everywhere to accommodate travelers, often with little regard for the lands that were supposed to be protected. Wildlife was fed for visitors’ amusement, but we’ve sadly learned the toll that’s taken on the parks’ first inhabitants. Stemming the flow of visitors in our busiest parks is a win-win for the environment and weary travelers who will have more space to revel in their majesty.”
