Final answer:
Theodore Roosevelt's deep connection with the physical world stemmed from his love for the outdoors, his dedication to conservation, and his personal ethos of the 'strenuous life'. His presidency saw the creation of numerous national parks and wildlife refuges, and the founding of the U.S. Forest Service, which are cornerstones of his legacy as a wildlife advocate and a conservation pioneer.
Step-by-step explanation:
Theodore Roosevelt developed a deep connection with the physical world due to his affinity for the outdoors and his experiences exploring the natural environment. From his outdoor lifestyle in the Dakota Territory to his conservation efforts as president, Roosevelt was a prolific advocate for preserving America's wilderness. This connection was further deepened by his partnership with conservationists like John Muir, his personal challenge of the strenuous life, and his role in significantly expanding the national park system.
As president, Roosevelt's vision included the sustainable use and preservation of the nation's resources, exemplified through his creation of multiple national parks, wildlife refuges, and the establishment of the U.S. Forest Service, led by Gifford Pinchot. His policies were driven by a belief in conservation for recreation and future generations, leading him to set aside 148 million acres of forest reserves and establish over 150 national forests, which are today remembered as his legacy as a wildlife advocate.
Roosevelt's personal resolve and experiences, such as overcoming health challenges and embodying the 'strenuous life', coupled with his passion for nature and wildlife, fueled his dedication to environmental stewardship and left an indelible mark on the nation's conservation policies.
