Parks and the Clean Air Act
By enacting clean air legislation, Congress expressed the national desire to preserve the scenic values we have come to expect in our national parks.
In spite of Big Bend’s remote location and presumed immunity to such urban problems as air pollution, noticeable changes in the park’s air quality appeared during the 1970s.
