-Land includes all the natural resources such as acreage and raw materials. In a primitive economy, land is the most important factor of production. For example, the Indians hunt, fish and collect honey or wild seeds. The forest is their main resource to produce the goods required for their survival.
This primitive form of economy now only applies to a few tribes in Amazonian, in Borneo or in Africa (the pygmies). Historically however, it was by far the most important. The hunting and gathering economy began 100,000 years ago when homo sapiens was born, and continued until 9000 BC. This date marks the appearance of a sedentary form of agriculture in a few areas of the planet.
