22 In the very first pages of Scripture we read these words: "Fill the earth and subdue it."(19) This teaches us that the whole of creation is for man, that he has been charged to give it meaning by his intelligent activity, to complete and perfect it by his own efforts and to his own advantage. Now if the earth truly was created to provide man with the necessities of life and the tools for his own progress, it follows that every man has the right to glean what he needs from the earth. The recent Council reiterated this truth: "God intended the earth and everything in it for the use of all human beings and peoples. Thus, under the leadership of justice and in the company of charity, created goods should flow fairly to all." (20) All other rights, whatever they may be, including the rights of property and free trade, are to be subordinated to this principle. They should in no way hinder it; in fact, they should actively facilitate its implementation. Redirecting these rights back to their original purpose must be regarded as an important and urgent social duty.
