#14 Why hell nope? This is a natrual volcanic hot spring on Iceland. And the powerplant you see in the background is actually using the hot spring as a resource to make power and heat for the island.
Due to sulfur the area smells like shit, but it's actually one of the cleanest powerplants in the world.

But yeah, I can see how ignorant people thinks this pool is wastewater from a polluting powerplant..
