Salar de Uyuni, the world’s largest salt desert, takes up hundreds of square miles in southwest Bolivia and is visible from space. Underneath it is by far the world’s largest lithium deposit, containing somewhere between 40 and 70 percent of the world’s total reserves. The mineral is used to power a wide variety of consumer electronics, and this GlobalPost report argues that the metal will become increasingly important as climate change drives the search for alternative forms of energy.
The Bolivian government sees the potential for windfall profits from the resource, and already has a lab on the Salar to experiment with various extraction methods. But as one Bolivian pointed out to me, widespread extraction would mean potentially scarring the view of one of the world’s most unique natural features. Big money for Bolivia maybe, but it would make the scene a little less romantic for the Argentinean couple off in the distance here.
From the family farm near Cochabamba where I WWOOFed for two weeks. It was an amazing place: a large variety of organically grown crops and animals to help sustain a family of five, run by a stay-at-home agronomist dad and his working biologist wife. The site produced almost no waste. Food scraps get composted or fed to animals, urine and dishwater are filtered for irrigation, dry toilets are cleared out every few months to make fertilizer, and inorganic stuff like plastic is stuffed into empty coke bottles that are then used as construction material.
