Final answer:
The Outdoor Recreation Resources Review Commission (ORRRC) was initiated by President Dwight D. Eisenhower to assess and develop federal outdoor recreation policies.
Step-by-step explanation:
The Outdoor Recreation Resources Review Commission (ORRRC) was initiated by President Dwight D. Eisenhower. The ORRRC was established to review the status and needs of outdoor recreation in the United States, assess the demand and availability of resources for outdoor recreation, and make recommendations on policies and programs. While the passage provided mentioned conservation efforts in the early 20th century and figures like Theodore Roosevelt and John Muir, who were deeply involved in conservation and national parks, it was later, during Eisenhower's presidency, that the ORRRC was created in 1958. The commission played a significant role in the development of federal outdoor recreation policy and laid the groundwork for future environmental legislation.
