The Mystery of the Pink Lake: Exploring Lake Natron

TLDRLake Natron, an unusually pink lake in East Africa, is home to an incredibly salty and alkaline environment. This unique ecosystem has two dominant microorganisms, the algae Dunaliella salina and the archaea Halobacterium salinarum, that have adapted to the extreme conditions. The lake's pink color is a result of the high concentration of dissolved salts and sodas. Lake Natron offers a glimpse into how life can survive in extreme environments, and provides insights into the ancient practice of mummification.
