ABSTRACT
The article offers new briefs in the U.S. The most popular parks, including Grand Canyon, are still infamous for their long traffic jams and large summer-time crowds. In Yellowstone, the daily average of 250 snowmobiles release 114 tons of carbon dioxide a year, and monitoring over the last three years shows that the machines have exceeded noise standards. The U.S. National Park Service monitors air quality trends in regard to visibility, ozone and the amount of sulfates, and other pollutants.
