I wholeheartedly recommend visiting Bolivia's Salar de Uyuni (and rest of the country like Yungas death road, Titicaca or Potosi mines) - it is estimated that it contains 50% to 70% of the world's known lithium reserves in brine underneath the solid crust. It is a nature's marvel, sitting 3600m high, becoming a 70km wide mirror during rains, having less than 1m altitude variations so satellites are calibrated on its surface. I sure hope for greener future but would shed a tear if this wonder would be destroyed in the process...
