s has increased the amount of wear an tear that park facilities sustain each year, and this increases the amount of repair requests and new structures that need to built annually. However, with a limited fund, these repairs and improvements often have to take a back seat to more pressing issues. While improvements to roads, trails, and facilities are important to the enjoyment of the park, the amount of park rangers available helps to protect the safety of park visitors. With shortages in funding the number of rangers at these parks is declining which impairs public safety. [27] at national parks is also threatened by the increasing popularity of these areas. More visitors means that there are more people approaching wild animals to take pictures and watch their В«natural behaviors.В» While these observations don't necessarily harm the animals if done discretely from a distance, there are a few irresponsible individuals who take risks to get close to animals. They harass the animals and provoke them in order to get an action shot or to prove their В«manhood.В» This practice not only puts the human at risk for injury or death, but it could also stress the animal and cause it to be injured. As funding is lost, private landowners may buy portions of land that once belonged to the park and set up cattle grazing areas, or put the land to some other use. The sale of national land depletes vital habitat for a wide variety of animals and increases the chances that diseases will be spread from domesticated animals to wildlife, or from wildlife to domesticated animals.concession system is another issue that is plaguing the national park system. In this case, private companies bid to sell their products in the park to visitors. While they are able to monopolize a market, and they are allowed to operate on national park property, they only return twenty five percent of the money earned to the government. This percentage doesn't make up for the amount of pollution they create from the tourists littering, or from the environmental impacts of their concession stand and sales.big concern is the potential exercising of mining claims on national parks. For example in the Grand Basin National Park in Nevada there are two hundred forty seven mining claims that still exist. If any of these claims were to be developed, it could dramatically impact the health of the ecosystems within the park, and it could threaten the health and sustainability of the park.pollution is yet another issue that national parks face. Acid rain caused by industrial and automobile exhaust impacts the health of water systems within national parks, and harms delicate organisms like amphibians and fish. Smog is also a problem that impacts the health and enjoyability of national parks. With more people visiting parks, vehicle traffic has increased and so has auto emissions near and in parks. This creates smog which can obscure the visitors 'views and impede their abi...
