TRANSCRIPT
The village of Wiscu sits on a barren, treeless, sloping landscape
in central Bolivia, nearly 12,000 feet above sea level.
Rocky ledges and boulders rise from thin mountain soil; it is clear that the best soil has long washed down the hillside.
Guinea pigs, not considered pets in Bolivia, provide
villagers with a desperately needed source of protein.
Guinea pigs are also low in fat and cholesterol.
Though destined for the dinner table, guinea pigs also play another part in the community’s food cycle…
However, the guinea pigs need to eat, too.
And fodder for animals is a scarce commodity
in the Andes Mountains.
The grass provides food for the guinea pigs, while the grass roots keep the soil in place and build up terraces for other crops.
