One of the biggest problems for the National Parks today is not problems from the interior of the parks or problems of claiming lands of the parks, but instead the claiming of land around the park. Mainly the claiming of land that might be upstream. As shown here on E&E news posted on 4/26/2010, water in the high sierras are being tested and found contaminated with the bacterias of Giardia and E. coli. The problem with these bacterias is they can not be seen and show no trace of their presence. A mountain stream with winter runoff could look clear and fresh but could be contaminated. Studies show that water is contaminated from livestock grazing, mainly cattle. Although, problems with livestock and parks has been constant since the formation of Yosemite back in 1890. Both Tahoe Research Center director Charles Goldman and Robert Derlet who has been studying water for 10 years think that land upstream of a National park, should also be created into a national park.
Commercialism in the National Parks
Ken Burn's recent documentary "The National Parks: America's Best Idea" has sparked a renewed interest in the National Park System. Burns recently spoke in front of a Senate Commerce subpanel, and according to E&E news, "senators of both parties, parks officials and local business owners agreed yesterday that improvements should be made in marketing the parks as tourist destinations." Diane Shober, director of tourism for the state of Wyoming, called for the National Parks' tourism budget to be expanded from $200,000 to 1 million.
