Suffocating sea compilation - 4K 影片檔

4K Underwater footage compilation of suffocating ocean. This video is shot in the delicate ecosystem of Oeresund (Øresund) in Denmark, and shows the result of farming activities, failure of wastewater management, sludge displacement, and urban construction projects. Most importantly, fertilisers and excess nitrogen runoff from farming leads to ocean eutrophication, promoting the rapid growth of algae and phytoplankton. As these organisms die and decompose, they deplete oxygen levels in the water, causing the formation of dead zones where marine life struggles to survive. Eventually, sulfur bacteria and toxic hydrogen sulphate gas on sea bed will kill all existing life, including sea grass, fish, mussels, crabs and other invertebrates. This tragic loss of marine biodiversity could be countered by responsible governmental regulations and green, technological solutions.
