Final answer:
In the 19th century, American attitudes towards wilderness changed, leading to an appreciation for nature's beauty and the beginning of the conservation movement alongside westward expansion. This transformation was influenced by figures like John Muir and promoted through the art of Western artists, while Manifest Destiny spurred settlement and economic development in the 'New West.'
Step-by-step explanation:
In the 19th century, American attitudes towards wilderness transformed significantly. Initially seen as chaotic and bewildering, the wilderness began to be appreciated for its beauty and potential thanks to figures like John Muir, who championed the idea that nature had spiritual and restorative qualities. This shift in perception coincided with America's westward expansion and the adoption of the concept of Manifest Destiny, with settlers and environmentalists alike exploring the 'New West' and uncovering economic opportunities along with a newfound appreciation for natural landscapes.
The rapid exploration and documentation of the West's uncharted territories by Western artists played a role in changing public perceptions about the wilderness. Their work, often idealizing the scenes they depicted, helped to capture the nation's imagination and reinforce the mythology of the American frontier experience. Furthermore, the era saw the beginnings of the conservation movement, driven both by a desire to preserve natural areas for recreation and by the recognition of the negative impacts of human activity on the environment, which laid the groundwork for the establishment of national parks and the modern environmental movement.
