A report found that 96 percent of 417 national parks have significant air pollution problems in at least one of four categories.
America’s national parks may seem like the perfect place to get away from the pollution that is rampant in many urban centers. But a study has found that 96 percent of the 417 national parks evaluated had significant air pollution problems in at least one of four categories: unhealthy air; harm to nature; hazy skies; and climate change.
“The poor air quality in our national parks is both disturbing and unacceptable,” Theresa Pierno, NPCA’s president and CEO, said in a statement. “Nearly every single one of our more than 400 national parks is plagued by air pollution. If we don’t take immediate action to combat this, the results will be devastating and irreversible.”
“When people think of iconic parks like Joshua Tree or the Grand Canyon, they think of unspoiled landscapes and scenic views,” Pierno said. “I think they would be shocked to know that these are actually some of our most polluted national parks. And in terms of harm to nature, 368 parks had levels of air pollution that damaged species and the local habitat.
“From microorganisms to large mammals, wildlife species are struggling to adapt,” the report read. “National parks are particularly vulnerable to changes in climate because of their sensitive natural environments and related risk of exposure to things like increased drought, flooding, fires and invasive species as well as sensitivity of plants, animals , water, glaciers, and historic and cultural resources.
