Material-Economic Resources of the USA (1856)
The mineral and agricultural resources of the United States are tremendous. Although the country was almost self-sufficient in the past, increasing consumption, especially of energy, continues to make it dependent on certain imports. It is, nevertheless, the world's largest producer of both electrical and nuclear energy. It leads all nations in the production of liquid natural gas, aluminum, sulphur, phosphates, and salt. It is also a leading producer of copper, gold, coal, crude oil, nitrogen, iron ore, silver, uranium, lead, zinc, mica, molybdenum, and magnesium. Although its output has declined, the USA is among the world leaders in the production of pig iron and ferroalloys, steel, motor vehicles, and synthetic rubber.
Agriculturally, the United States is the first in the production of cheese, corn, soybeans, and tobacco. The United States is also one of the largest producers of cattle, hogs, cow's milk, butter, cotton, oats, wheat, barley, and sugar; it is the world's leading exporter of wheat and corn and ranks third in rice exports. In 1995, US fisheries ranked fifth in the world in total production.
Main US exports include motor vehicles, aircraft, food, iron and steel products, electric and electronic equipment, industrial and power-generating machinery, chemicals, and consumer goods. Leading imports include ores and metal scraps, petroleum and petroleum products, machinery, transportation equipment (especially automobiles), and paper and paper products.
The major US trading partners are Canada (in the world's largest bilateral trade relationship), Mexico, Japan, the United Kingdom, South Korea, and Germany. The volume of trade has been steadily increasing.
The development of the economy has been stimulated by the growth of a complex network of communications not only by railroad, highways, inland waterways, and air but also by telephone, radio, television, computer (including the Internet), and fax machine. This infrastructure has fostered not only agricultural and manufacturing growth but has also contributed to the leading position the United States holds in world tourism revenues and to the ongoing shift to a service-based economy.
