Air Pollution Threatens U.S. National Parks and their Tourism Revenue

Douglas McIntyre, editor-in-chief of Climate Crisis, discusses how air pollution is harming U.S. national parks, particularly in California. Sequoia National Park, home to millennia-old trees, is affected by smog from Los Angeles and wildfire smoke, discouraging visitors and impacting tourism revenues. The problem is not confined to California, as pollution from wildfires also reaches iconic parks such as Yellowstone. The discussion underscores how pollution in one region can have far-reaching effects on the nation’s natural treasures.
