For the past fifteen years Yellowstone National Park has been educating more than one million people a year on ways to reduce trash and be a good steward to the land. Yellowstone is observing its 15th year of the "Greening of Yellowstone" program this week.
Park Environmental Protection Specialist Jim Evanoff says that dealing with trash within the park has been a primary goal of the program since its inception.
Another benchmark for the park is the fact that the entire fleet of Yellowstone vehicles uses renewable fuel blends. A new project this year consists of harnessing the power of water without building a dam. Evanoff says a water pipe with a 1000-foot drop is being fitted with an internal turbine.
Evanoff said that the reduction in trash is not only important for environmental reasons, but that it plays a big role in overall safety in the park as well. Diverting trash outside of the park helps keep incidents between bears and humans fewer and far between.
