California is the world's fifth-largest supplier of food. Its Central Valley — a rich plot of agricultural gold that's nearly the size of West Virginia — is where America gets virtually all of its almonds, tomatoes, pistachios, lemons, and artichokes.

Next time you grab a handful of almonds, think about the fact that every single one of those deliciously crunchy nuts required an entire gallon of water.

Happy snacking!
