Deforestation caused by human beings has been a problem for many societies since humans mastered agriculture to the present day. Once humans began to urbanize society, they began to deplete the natural resources around their settlements. Total deforestation and resource depletion was devastating for any culture that caused it. The Native American society that flourished in the Cahokia Mounds area of southern Illinois probably disappeared because they depleted their resources including deforestation for fuel and building materials as well as clearing land for planting domesticated crops. . . .
