'Sea snot' covering Sea of Marmara sparks concerns over global warming and water pollution
This aerial clip shows marine mucilage on the surface of the Sea of Marmara, Turkey.
Fishermen and marine experts have spoken about their concerns regarding the proliferation of mucilage.
The "sea saliva" is caused by the accumulation of nitrogen, phosphorus, and carbon in industrial and agricultural wastewater. Global warming is also believed to exacerbate it.
The footage was filmed on May 9, 2021, over Izmit Bay, Turkey.
