What does the olive branch on the United Nations flag mean?

The official symbol of the United Nations is a map of the world from the North Pole, surrounded by an olive branch. The background color of the United Nations flag is light blue, and the pattern in the middle is the white United Nations emblem. The olive branch symbolizes world peace and security, and circling the earth symbolizes the purpose of the United Nations and the maintenance of unity. Why use the olive branch to symbolize peace? There is a myth about Noah's Ark. In ancient times, one day, God found that the moral consciousness of human beings was getting worse and worse. He was very angry and decided to engulf all human beings with floods. But after careful investigation in all directions, I finally learned that a couple named Noah had good moral values, and God gave them the right to live. God told Noah and his wife to prepare a big square wooden boat with enough dry food and water, and to select all kinds of animals to board. When the flood came, all the creatures in the world failed to escape this disaster, only Noah's Ark was still drifting on the water. After a long time, the flood gradually subsided, and mountains, islands and land appeared in the distance. Noah and his wife were very happy, so they put a pair of pigeons on the boat and set them free. Soon, the dove flew back with an olive branch in her mouth, which meant that the earth was alive and everything was peaceful.

This small disk with a diameter of 16 inch shows the projection from the north pole center of the world map to 40 degrees south latitude, and draws four latitude circles. In order to show that the United States is the host country of the conference, the vertical axis of the projection is located at 100 degrees west of the prime meridian, so that the United States is at the center of the graph. The background color of the graphic is smoky blue, which is not used by the national flags of the participating countries, while the other parts of the graphic are golden yellow and covered with enamel. An olive branch symbolizing peace is added to the periphery of the figure. The Olive Branch is based on the story of Noah's Ark in the Bible, which symbolizes peace and hope.

The whole emblem is a plane projection of the world with the north pole as the center and equidistant directions. The land on the map is light blue and the waters are white. Its eight meridians extend to 60 degrees south latitude, and the latitudes are represented by five concentric circles, symbolizing that the United Nations is a worldwide international organization. The pattern is supported by a garland composed of two crossed golden olive branches, symbolizing world peace. The "national emblem" also has the abbreviation "UN" of the United Nations. Blue and white are the official colors of the United Nations.
