A Naturally Occurring Bright Pink Lake
Lake Retba, in the Cap Vert peninsula of Senegal, is also known by another name – Lac Rose. Why? Well, for one reason, the entire lake is colored bubblegum pink. 
The lake has a particularly high salt content, and like that of the Dead Sea, allow people to float naturally. But the salinity also makes the water conducive to the algae Dunaliella salina, which is known for its healthful antioxidant properties for humans, and also makes the water look like pink lemonade.
The world is an amazing place.
