Final answer:
The author included the passage to emphasize the historical contributions of Theodore Roosevelt and other conservationists in establishing policies to protect Yellowstone National Park and natural resources in the U.S., a key aspect of American conservationism.
Step-by-step explanation:
The author included the passage about Roosevelt and his fellow club members working to protect Yellowstone National Park to highlight the efforts made towards conservation of natural resources in the United States during that period. These efforts by conservationists, including editorial writings, speeches, and lobbying lawmakers, were crucial in establishing policies that protect these resources. The passage serves to underscore the importance of these actions and how they were instrumental in safeguarding the park from exploitation, which is a significant theme in the historical narrative of American conservationism.
President Theodore Roosevelt's legacy in conservation was multifaceted; not only did he establish national parks and wildlife sanctuaries, but he also supported the creation of state agencies to regulate hunting for conservation purposes. Despite the controversial impact on the traditional ways of Native Americans and other rural dwellers, his efforts have had a lasting influence on the preservation of wilderness and the prevention of overhunting.
The article states the culmination of conservation efforts with the creation of the National Park Service during the Wilson Administration, a result of the mobilization of public support for conservation that was strongly encouraged by Roosevelt's own dedication to outdoor life and passion for preserving America's natural resources.
