That same year, the Environmental Protection Agency and the National Park Service teamed up to carry out the most sophisticated air pollution study every conducted, the B.R.A.V.O. Objectives of this study were to quantify the impacts of major pollution sources from Mexico and the United States on Big Bend National Park, determining what makes up park air pollution, the role of weather in park haze, and the paths that air pollution follows to reach the park. Data was collected from 42 different sites throughout Texas. When the results are released, park managers hope to gain a deeper understanding of what is causing the decline in park visibility and a wealth of needed information on how to protect the wonderful views of Big Bend National Park. What You Can Do Let people know that you care. Learn about local efforts and issues.
Public libraries contain references on various topics addressing air pollution.
Talk to your state or federal environmental agency to find out what it is doing in your area. During your visit to Big Bend join a ranger for a guided walk or evening presentation to learn more about issues affecting park resources. Get involved in local efforts by supporting ballot measures and candidates sensitive to air quality issues. Since automobiles are a major source of air pollution, how you drive and care for your car is important. Use an energy-conserving grade motor oil, use reformulated or clean fuels, and drive at a medium speed.
