This document discusses how climate change threatens natural beauty in national parks. It notes that while national parks aim to preserve natural landscapes, changing weather and a warming climate cannot be sheltered by laws or fences. The document explains that the National Park Service faces the challenge of preserving natural and cultural resources while making parks accessible, but this is difficult when the environment changes but park borders do not. It also states that while animals can migrate, trees that provide color, beauty, and shade to national parks are at risk from climate change as they cannot quickly relocate.
