The world would most likely fall into chaos. I'd have a giant kingdom with an army of rabbits (they can be very scary you know) and an island full of zombies that will barf up rainbows. The sun will magically have a giant smiley face upon it's surface and it will forever be smiling down upon the burning cities and raging zombies. No, not all cities will be filled with zombies and fire, I will have paradise where China USED to be. Paradise filled with rivers of wine (man made of course) and pools and lakes filled with clear fresh water. There will be banquets and balls and dinners and parties and EVERYONE will have something there that will make it pleasurable for them to stay in paradise.
Believe me. . . this wasn't my first thought of what I'd do with the world.
