3: Making the World Go Round Presented by Michel Pelssel
In the Tibetan Kingdom of Zanskar there is no word for technology. To them, machines were invented to grind corn, or to make incense-not to make money. Yet the technology is there - to irrigate their high-altitude desert valley, to build their houses, to get gold from the rivers, to cure their horses, trap the wolves and to extract the dyes, medicines and insecticides from the many plants that grow in the short summer.
Film editors PETER SYMES , DAVID FARLIE Produced by PETER MONTAGNON (Nodrup's Monastery: Thursday 7.30)
