Million of years ago, a part of the Pacific Ocean found itself cut away and included in the rise of the Andes Chain. Eventually, all water evaporated and left a huge plain full of salt. It is a strange feeling to drive up to 150km on a virgin white surface. Seems like ice and that the ground is going to break at any time. The Uyuni Salar is obviously used to provide salt to all of Bolivia, even though the workers conditons are reminiscent of decades ago. Given the amount of supply, there is enough for billion years I guess. (click on pictures for high res)
