Senegal's Lake Retba, or as the French refer to it Lac Rose, is pinker than any milkshake.

Lake Retba has a high salt content, much like that of the Dead Sea, allowing people to float effortlessly in the massive pink water.

The remainder of the ice shelves which used to extend roughly 3900 square miles over the Weddell Sea had completely disappeared by 2002. Global warming is changing the habitat for all Ice dwelling inhabitants.
