Almost half of the earth's surface is covered by rangeland, a renewable resource, a primary source of food, fiber, and contentment--the three needs basic to human life.  As world population continues to expand at the annual rate of about 1.7 percent, the priority for food production remains foremost closely followed by the need for proper clothing and housing for an ever growing population. With affluency comes a demand for more nutritious food, better living conditions, and enhanced improvement in esthetic and recreational opportunities. This Nation's and the world' s rangelands can help provide basic needs in the form of goods, services, and values, as demanded by society.
