    Why are clean air and natural quiet in national parks being threatened?
    Growing national park visitation exacerbates traffic congestion and associated air and noise pollution. Pollution also comes from outside sources, including nearby and distant power plants and industries. Air pollutants have quantifiable effects on visibility, ecology, human health, and the economy of gateway communities surrounding parks.

Visitors find that many parks contain significant levels of noise and air pollution, and traffic congestion similar to that found on the city streets they left behind. |
