In movies, the apocalypse is always caused by something fast and tragic: a giant meteor colliding with the earth, a nuclear blast, a massive earthquake that destroys New York and triggers tsunamis around the world. Christine never believed that this was how life as she knew it would end. She always thought world war three would be fought over the last barrel of oil. People would become desperate, hungry, with no fuel to run tractors, to move produce to markets. History showed that starving people were desperate people. Violence would break out. Machinery would break down and stop running. It would be worse in the cities than the country. People who lived in cities relied on the system. Without fuel, and food, the system would break down. As the machinery of society broke down, people would stop going to work. Paychecks wouldn't fill an empty belly. Necessities that people had become accustomed to would fail. Basic sanitation would stop. The sewage plants would back up and the water would be undrinkable. Christine knew that survivors would have access to guns, water, and would know how to hunt and farm.
