Chinese lake turns pink on one side, remains green on other
The 500-million-year-old Yuncheng lake in China has turned pink on one side while remaining green on the other. The annual phenomenon is the result of rising temperatures and light intensity causing organisms called Dunaliella salina to change their hue. Yuncheng lake is called the 'Dead Sea' of China as its salinity is nearly equivalent to that of the Dead Sea.
