For hundreds of years until recently, Turks and Arabs occupied structures originally built by the Romans 2,000 years ago. The abandoned ancient buildings saved the late-comers the trouble of doing their own construction. Another example is the use of dressed stones in locations far away from where they were dressed. One finds the lintels of doorways from ancient Palestinian synagogues in contemporary homes in Syria. Humans' activities tend to increase the order and decrease the randomness of nature.
Production brings like elements together.
This concentration can be exploited by subsequent generations. Consider lead batteries in a dump, or the war rubble from which Berliners built seven hills which are now lovely recreational spots. Furthermore, humans perceive order, and create it. One can see this from the air if one looks for the signs of human habitation. Still more generally, humans have for tens of thousands of years created more than they have destroyed.
