Long run aspects of environmental protection and of the use of resources are analyzed within a planning model. To this end fundamental concepts of thermodynamics are explained in a simple manner. The relationships between entropy, energy necessary for the extraction of a resource and the concentration of the resource is employed to establish a connection between the economic system and the environment.
