Senegal’s iconic Pink Lake, also known as Lac Retba, has regained its signature pink hue after nearly three years of discolouration caused by excessive rainfall, climate change, and pollution due to human activities. Apart from being a tourist attraction and being on UNESCO’s tentative list of World Heritage sites, the lake, which is located in Dakar, supports a thriving salt production industry, with thousands of people relying on it for their livelihoods | TRT Afrika
