Lithium is the third element in the Periodic Table of the Elements. If you haven't seen this movie, drop everything and go NOW. Besides being used as a treatment for anxiety, Lithium is also used in the manufacture of batteries, most notably laptop batteries, but also batteries that are used in electrically powered automobiles. There is much speculation that electric vehicles are the wave of the future, and as such, any resource that is necessary to the manufacture of such vehicles must take its place as one of the prime resources on the planet. There's an interesting article here about where most of the planet's Lithium comes from. It's a really nice looking place, too.
