Answer:
Endangered Species Act of 1973
Step-by-step explanation:
The Endangered Species Act of 1973 was signed into law by president Richard Nixon. The Act provides legal measures for the protection of endangered species in the U.S. territory.
The provisions of the Act are enforced by the National Marine Fisheries Service, a division of the U.S. Department of Interior, and the United States Fish and Wildlife Service, a division of the NOAA ( the National Oceanic and Atmospheric Administration).
The act classifies endangered species in four categories: delisted, threatened, endangered, and extinct.
