Introduction The United States established Yellowstone as a national park in 1872 and initiated the worldwide movement to protect such areas as national treasures. One hundred years later, during the Nixon administration, the United States proposed the World Heritage Convention to the international community and was the first nation to ratify it. The World Heritage Convention, the most widely accepted international conservation treaty in human history, is the American national park idea being carried out worldwide.
