The Endangered Species Act of 1973 (ESA; 16 U.S.C. § 1531 et seq.) is one of the few dozens of US environmental laws passed in the 1970s, and serves as the enacting legislation to carry out the provisions outlined in The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). Designed to protect critically imperiled species from extinction as a "consequence of economic growth and development untempered by adequate concern and conservation", the ESA was signed into law by President Richard Nixon on December 28, 1973. The U.S. Supreme Court found that "the plain intent of Congress in enacting" the ESA "was to halt and reverse the trend toward species extinction, whatever the cost." The Act is administered by two federal agencies, the United States Fish and Wildlife Service (FWS) and the National Oceanic and Atmospheric Administration (NOAA).

The near-extinction of the bison and the disappearance of the passenger pigeon helped drive the call for wildlife conservation starting in the 1900s. Ornithologist George Bird Grinnell wrote articles on the subject in the magazine Forest and Stream, while Joel Asaph Allen, founder of the American Ornithologists' Union, hammered away in the popular press. The public was introduced to a new concept: extinction.
Market hunting for the millinery trade and for the table was one aspect of the problem. The early naturalists also killed birds and other wildlife for study, personal collections and museum pieces. While habitat losses continued as communities and farmland grew, the widespread use of pesticides and the introduction of non-native species also affected wildlife.
One species in particular received widespread attention—the whooping crane. The species' historical range extended from central Canada South to Mexico, and from Utah to the Atlantic coast. Unregulated hunting and habitat loss contributed to a steady decline in the whooping crane population until, by 1890, it had disappeared from its primary breeding range in the north central United States. It would be another eight years before the first national law regulating wildlife commerce was signed, and another two years before the first version of the endangered species act was passed. The whooping crane population by 1941 was estimated at about only 16 birds still in the wild.
