CNN News | The majestic views overlooking the Grand Canyon make it one of America's favorite destinations, but a new report finds several man-made threats are contributing to the deterioration of Grand Canyon National Park.
Scientists and park staff working on the "State of the Parks" Grand Canyon report highlight areas and resources in the park that are threatened, the history of those threats and what can be done to correct them.
What they found is a national park that continues to decline from factors ranging from climate change to mining to aircraft flyovers as well as management of the Colorado River upstream from the canyon.
