Final answer:
The National Hunting Act of 1945 is not a recognized federal act. While numerous environmental conservation and preservation laws have been enacted throughout U.S. history, the National Hunting Act of 1945 is not one of them.
Step-by-step explanation:
The question at hand is to identify which of the provided options is NOT a federal act. The options given are the National Trails System Act of 1983, the Land and Water Conservation Act of 1965, the Wild and Scenic Rivers Act of 1968, and the so-called National Hunting Act of 1945.
Throughout American history, various environmental policies and acts have been passed, including the National Environmental Policy Act of 1969, Clean Air Act of 1963, Clean Water Act of 1972, and the Endangered Species Act of 1973. Through public initiatives and presidential influence, such as that from Presidents Lincoln, Grant, and Roosevelt, conservationism has been a significant part of the nation’s legislative agenda, leading to the creation of national parks and the enactment of laws to protect wildlife and natural resources.
However, among the listed options, the National Hunting Act of 1945 is not a recognized federal act. Historically, there have been different acts such as the Migratory Bird Treaty Act of 1918 and later, the Endangered Species Act of 1973, but there is no legislation known as the National Hunting Act of 1945.
