Conservation
National parks are facing difficulties in their sustenance because of increasingly large crowds, chronic underfunding, and climate change. This leads to habitat degradation and disruption of wildlife, since climate change alters the wildlife's natural environment, overcrowding can increase pollution and disturb animals, and the lack of budget can force the staff to cut people and other important technologies for the animals. Because of this, it can be difficult to maintain these national parks, which can cause harm to wildlife and damage to fragile landscapes.
