The sulphur carriers, small skinny toothless men who carry over 80 kg of yellow mineral on their shoulders from the bottom of the crater to the valley 20 km away, for a ridiculously low wage, have a life expectancy of just 40 years with an unpleasant and dangerous job in the midst of sulpher fumes. They are members the Treters cooperative in Indonesia at the foot of the Welirang mountain, over 3000 metres high,and they live in huts where they suffer from the cold during the night. Their only wealth is the hut and the sulphur wrenched from the mountain.
