Environmental issues

Animal species in Yosemite have slowly been declining due to the environment.  Some environmental issues like climate change, are especially challenging to the animals because they originate outside the park.  Invasive species have a negative impact on natural resources in Yosemite.  Some species are cleaning out the food leaving not enough for the other animals in the park.  Increased noise also disrupts wildlife behavior and it makes it hard to locate prey and display complex communication methods.  The environment for these animals can be changed depending on how we act to preserve the park.
