Answer: Abundance of halophilic green algae
Notes: Lake Retba, also known as Lac Rose or the Pink Lake, is located north of the Cap Vert peninsula in Senegal. Threatened by pollution and mining, its waters, primarily sourced from the sea, are home to halophilic green algae, Dunaliella salina. The algae's red pigments give the lake its distinctive pink color. A popular tourist destination, the Pink Lake's unique hue comes from the alga's salt-resistant qualities, supported by carotenoid pigments rich in vitamins and trace elements.
