More ethnic Tibetans in western China have been forced to find new ways of making ends meet, as the caterpillar fungus that was once a staple of their income, has become increasingly rare.
A rare fungus, also known as " Himalayan Viagra," is both a source of income and violence across the Himalayas in Nepal.
The caterpillar fungus, a cash cow for Tibetans, may die out in China in two decades, as a result of overexploitation on the Qinghai-Tibet Plateau, experts have warned.
