Red alert for China’s waters - World - Macleans.ca

There are two mythic rivers that run through China. One, the Yellow River, takes its name from the colour it naturally takes on as it carries clay from the Szechuan highlands to the sea. The other is the Yangtze, which is not supposed to have an unusual hue—but last week it suddenly flowed through the city of Chongqing a shocking, garish orange-red, a colour you would expect to find on fingernails or a car.
