Senegal's 'Pink Lake' recovers its rosy hue, reviving salt trade

Senegal's Lake Retba, commonly called the Pink Lake, has recovered its distinctive rosy hue, which has subsequently revived the local salt trade. The lake's unique coloration is produced by microorganisms, specifically Dunaliella salina algae, which thrive in highly saline conditions. This biological phenomenon allows the lake to maintain its vibrant appearance while supporting the economic activity of salt extraction, marking a return to previous levels of productivity for the regional salt industry.
