Growing up near Bolivia's Uyuni salt flats, Franz Ali Ramos remembers playing in the high-altitude wetlands near his home during the rainy season.

Now, the wetlands have given way to cracked, sunbaked earth a change that Ali Ramos blames on nearby operations by Bolivia's state lithium corporation, Yacimientos de Litio Bolivianos (YLB).
