What can we do about the air?

Protecting air quality, and resources sensitive to air quality, in the National Park System is a complex task that includes: active research and monitoring about the amount and effects of pollution in NPS areas; advocacy for pollution controls when they are likely to affect NPS areas; and education about the importance of clean healthy air to the NPS.
