The Salar De Uyuni, one of our favorite parts of our 2008 trip in Bolivia, is now at risk of serious changes. It seems that 70% of the world's known reserves of lithium which is of course an important element for all of the lithium-ion batteries in the cellphones, ipods, cameras, and laptops that people take on their trips to the salt flats to document their trip.

This time it was two grocery store employees together, two pairs in delivery trucks, and then the one that inspired me to write this post.
