Oruro, Bolivia – I’m walking through a mining tunnel in Bolivia, dark but not too narrow, with a deafening brass band marching behind me. A stumbling drunk miner stops to urinate on the wall near me. The choking smoke of a bonfire inside the mine mixes with the sharp tea-like smell of the coca leaves the miners are chewing. Just ahead of me other miners are carrying four trussed-up llamas, drenched with beer and festooned with ribbons and confetti. The miners forced firewater down the llamas’ throats in a ceremony at the mouth of the mine and now they are bringing them into the mine to sacrifice them and ask for safety and abundance in the dangerous shafts.
