The Earth Kingdom has a vast economy primarily based on agriculture, incorporating significant industrial elements as well. The Agrarian Zone of Ba Sing Se is a large, open farmland. The Water Tribe does have a form of currency, commonly referred to as Water Tribe money by other nations. Icebending is their primary form of construction. Ice is used as the main building material of buildings, walls, dikes, locks, and other structures, as it is a medium of their bending. One of the most prevalent natural resources of the Northern Water Tribe is ice. Since the end of the Hundred Year War however, the Water Tribe economy has developed to a more global scale, leveraging their maritime skills to become a leading force in the international shipping industry. Naturally, hunters and fishermen of the Water Tribes are some of the best in the world in their field. Skins from seals are used to create tents, while pelts from furry animals are used as clothing and to cover barren surfaces. Squid and seaweed can be used to make a wide variety of dishes, including soup, seasoning, and even bread and cookies. Sea prunes are a favorite, while giant sea crabs are considered a delicious delicacy to those in the Northern Sea. The Water Tribes are inherently dependent upon the oceans for a majority of their natural resources and well as the bounty of the frozen tundra. Trade with the other nations is rare, as the Water Tribe does not have many items available for the purpose nor many opportunities for trade. The Water Tribe economy is small and primarily focused on sustaining the survival of the tribe. The currency of the Water Tribes is blue in color. Monk Jinpa served as head of administration at the Southern Air Temple in 296 BG before being appointed as the personal secretary of Avatar Kyoshi. The air temples had administrative groups to handle logistics and finance when the Air Nomads were forced to deal with the material world. Industrialization was also largely neglected, as the use of airbending as their principal source of power rendered machinery and vehicles largely unnecessary. The Air Nomads practiced subsistence agriculture, growing enough food and crafting enough of the necessary implements to sustain their own survival without the need to trade with others.
