Ulpukka (Nuphar lutea)

In this lake in southern Finland, Kaarina, Littoinen, there is a lot of blue-green algae. It is recommended not to swim in this lake or if you do, you should soon after swimming take a shower -at your house. You should also avoid any contact with water and your eyes or mouth. It is recommended not to let children or animals in the water at all. I tried to take a serious and cold picture of the state of our environment.
An earlier photo in the same place Tuesday 29 June 2010 looks quite different.
