On December 28, 1973, RN pledged to protect the nation’s endangered species from extinction. The move was part of his sweeping environmental agenda which included the National Environmental Protection Act and the creation of the EPA, the Clean Air and Clean Water Acts, and the Mammal Marine Protection Act:

I HAVE today signed S. 1983, the Endangered Species Act of 1973. At a time when Americans are more concerned than ever with conserving our natural resources, this legislation provides the Federal Government with needed authority to protect an irreplaceable part of our national heritage–threatened wildlife.

This important measure grants the Government both the authority to make early identification of endangered species and the means to act quickly and thoroughly to save them from extinction. It also puts into effect the Convention on International Trade in Endangered Species of Wild Fauna and Flora signed in Washington on March 3, 1973.

Nothing is more priceless and more worthy of preservation than the rich array of animal life with which our country has been blessed. It is a many-faceted treasure, of value to scholars, scientists, and nature lovers alike, and it forms a vital part of the heritage we all share as Americans. I congratulate the 93d Congress for taking this important step toward protecting a heritage which we hold in trust to countless future generations of our fellow citizens. Their lives will be richer, and America will be more beautiful in the years ahead, thanks to the measure that I have the pleasure of signing into law today.
