Before 1540 when Europeans immigrated to the Grand Canyon, this site was used as a habitat for Native Americans and later as a pilgrimage site for the Pueblo peoples. When Theodore Roosevelt became President of America he worked hard to preserve the area as he appreciated its great beauty, and also enjoyed hunting there. Today, the Grand Canyon lies within the Grand Canyon National Park, which in itself is considered a natural wonder of the world. This park is used to conserve the area that it comprises, allowing tourists to visit and explore it safely, without damaging any of the natural structures.
The Grand Canyon has also been declared a World Heritage Site by UNESCO, which (along with the fact that it is a national park) has helped to protect it from various proposals, such as the damming of the Colorado River that runs within it.
