Wallace Stegner's quote emphasizes the intrinsic value of wilderness to our identity as a people. He suggests that allowing the destruction of remaining wild areas would signify a loss of something essential in our character. Wilderness represents a challenge that has shaped who we are, and preserving it is crucial for maintaining our connection to our roots and our humanity.

In Kevin Fedarko's book "The Emerald Mile," this theme is central as it explores the relationship between people and the natural world. It highlights the importance of safeguarding what little wilderness remains, pointing out that these areas hold not only ecological significance but also a vital part of our cultural heritage and identity. Stegner's words remind us of the responsibility we bear to protect these sacred spaces for future generations.
