Weisman identifies natural forces that lead to the destruction of human-made structures, such as rust, bird droppings, and leaves. Without human intervention, these causes can lead to significant deterioration over time. The discussion highlights the vulnerability of infrastructure to environmental processes when maintenance stops.

These elements, when left unattended, can cause significant deterioration and ultimately lead to collapse. The interconnectedness of these natural processes emphasizes the fragility of our infrastructure without human maintenance. ;
