Great Passion Fruit Famine

The  was an event in world history mentioned by Sierra Petrovita in Fallout 3.

Background
Little is known about the causes of the famine, but it can be assumed that passion fruit crops died out en masse. During this time, the soft drink company, Nuka-Cola, had to change the flavor of its trademark soft drink because the supply of fruit (passionfruit in particular) was so low. Because there is no real geological evidence to suggest there was actually a large die out, and there were certain events, such as the Vaults being built, occurring around the world at the time, it is possible that as Vaults went heavily into production, large amounts of canned foods and such were required to stock them. This would have caused a severe effect on the public markets, so it is possible that perishable foods were diverted to the Chinese and Alaska front lines for the soldiers while the non-perishables went to 106 or Raven Rock in order to hide the fact that the U.S. government's secret project was underway.

Effects
Passion Fruit was one of the many fruit flavors used in the making of Nuka-Cola. Despite having been introduced only a few months before the famine, people noticed the change in flavor.
