KANGDING, SICHUAN, CHINA - 2003/09/01: Selling mushrooms at a makeshift street market in Kangding, a small border town between Tibet and China. Fungi fertile, the land creeping onto the Tibetan Plateau hosts some of the most exotic mushrooms in the world, like Matsutake and caterpillar fungus, both sold for top prices in the markets of Beijing, Tokyo and Hong Kong. For many Tibetans, collecting the different mushrooms now provides up to 80% of their once subsistence incomes. (Photo by Leisa Tyler/LightRocket via Getty Images)
