Climate change is a big environmental factor for this park. This can be very harmful to the animals living there. They could have to relocate to a different location. It has decreased the amount of snowfall in the park. This affects everything you see when you come to the park, as well as everyone and everything living downstream. Warmer temperatures are quickening the melting of glaciers. They are also reducing snowpack which is really bad. Thawing permafrost disrupts the structural basis of large regions. Climate change can have a very big impact on Yellowstone and it must be reduced.
