Question: 3 percent of antarctic ice is penguin urine?
Answer: It is been reported that 3% of the glaciers in Antarctica is composed by the urine of penguins, and which is indeed an amazing fact. Since the temperature over there is much below 0 centigrade. The urine of penguins has to freeze in the ice, and the urine has no scope to get washed off or can get evaporated out.
