I think that the national park service should make eletric shuttle trains that runs from the entrance to the rim of the canyon, so people could help the national park with the polution problem and also the cayon will look more better and the view will be clear. Also I think that ther should be less air plan tours through the canyon because even the plans give off alot of carbon monoxide. experts say that most of the haze(the dust like polution in the canyon) is from the tuorist transportation,such as the trains, power plants, transportation, ect....
So that is what I think the Grand Canyon national park should do.  
 

I think that this picture is fuzzy because of the haze in Grand Canyon. Grand Canyon    
Has pollution because of the power plant and forest fires make pollution an that is way it is fuzzy at Grand Canyon.
