We’re all familiar with the plot of a movie that occurs in a city still standing in a post-apocalyptic era. The streets are empty, except for a few survivors who wander aimlessly, searching for signs of life. Buildings begin to crumble and rust away after years of neglect, public transportation sits idle, and overgrown weeds spring from the cracks in the unmanaged sidewalks and streets. The scene feels eerie because we can’t imagine letting our physical environment sit in decay. It seems impossible that our built environments where we live and work each day suddenly fall silent. It’s a city without a pulse.
