The U.S. established the first national park, Yellowstone National Park, in 1872. Located primarily in Wyoming, it was created to preserve the unique geothermal features and abundant wildlife within its borders. The park's formation marked a significant milestone in environmental conservation, as it represented a commitment to protecting natural landscapes for future generations. Yellowstone served as a model for the establishment of national parks worldwide, promoting tourism and scientific study while emphasizing the importance of preserving natural beauty. This initiative reflected a growing appreciation for nature and the desire to protect it amid increasing industrialization and urbanization.
