What killed 500 fish: Human pee or ice-skating?
Fishermen in Germany are blaming swimmers for peeing in a lake near Hamburg, resulting in the deaths of some 500 fish.
The fishermen contend that the large amount of phosphates contained in urine have caused large amounts of algae to grow, suffocating many fish.
