Natural resources and environmental technology

People require certain things to live. These are the essentials for living. Food, clothing, and shelter are included. Each of these comes from the resources that are naturally found on the earth. Without these resources, human life would not be possible. What about the future? Will we run out of resources? More people require more of the earth's resources. In some cases, the earth's resources are remaining constant. New resources are not being found or are formed very slowly. Understanding natural resources helps us to be better users. - p. 1.
