In economics all resources are considered those means that contribute to the production and distribution of goods and services that use human beings make. Economists understand that all resources are always scarce in the range and diversity of human desires, which is like explaining the needs and defined precisely in the economy as the science that studies the laws governing the distribution of those resources among the various possible ends. Under this view, natural resources relate to factors of production provided by nature without prior amendment made by man, and differ from human and cultural resources that are not generated by humans (such as processed goods, the work or technology). The use of any natural resource brings two concepts to consider: resistance, which must be overcome to achieve operating and interdependence.
