The Endangered Species Act (ESA) was passed by Congress in 1973 during the Nixon administration. The ESA is a law that provides for the protection of endangered and threatened species and the habitats in which they live. It is aimed at preventing extinction and promoting the recovery of listed species.
The Environmental Protection Agency (EPA) was also established under the Nixon administration in 1970. The EPA is a federal agency responsible for protecting human health and the environment by enforcing environmental laws and regulations, conducting research, and providing information to the public.
Therefore, the acts that were passed under the Nixon administration were the Endangered Species Act and the establishment of the Environmental Protection Agency.
