The Wilderness Act, enacted in 1964, is a landmark piece of legislation that established a legal framework for the preservation of wilderness areas in the United States. It aimed to protect untouched natural lands from human development and exploitation, ensuring that these areas remain untrammeled by man and provide opportunities for solitude and recreation. The Act reflects the growing environmental awareness during the 1960s and is a crucial component of the broader conservation efforts that were part of the era's progressive policies.
