With Global Warming and Desalinization costs at an all-time high, fresh water has become a scarce resource reserved for the wealthy. Very little fresh water is circulating throughout the world. Wars break out over water, and eventually these wars escalate to a dark degree. Almost all major countries are fighting against each other, a World War III. Countries' tempers burn hotter and hotter, and they break the laws of war more and more. Someone in America pounds his fist on the table, and screams the order to nuke China. China and it's allies retaliate with more nukes. Two months later, the world has no armies, and a nuclear winter spans North and South America, Africa, Europe, and Asia. With the cities in ruins, and the water and food poisoned from fallout, life becomes endangered on Earth.
