This unfortunate situation has many direct and indirect impacts.

Some of these include:

• Biodiversity – As the thick and slimy mucus covers the surface of Turkish Marmara Sea, fishes are dying due to reduced oxygen levels, disrupting the ecological balance.
• Socio-economic – it has disrupted the local ecosystems. Boats travelling through the Sea of Marmara are finding it difficult to navigate the grey sludge whereas fishermen are being prevented from working as it clogs up their nets and motors. As the sea snot floats to the surface, it dries up and began to release foul smell of decomposition, impacting tourism negatively in the nearby areas.
• Mucilage inhibits the transfer of oxygen as it covers an area of the sea surface up to 30 meters deep. It kills the immobile organisms in the sea such as the mussels, oysters, and pina especially sponges and corals. The mucilage also harms fish larvae and eggs, having an impact on the fishing industry in years to come.
• It has also been proposed that the mucilage bloom in the Marmara Sea may kill life in the Black Sea, the world's largest body of water without oxygen. The Danube River carries pollution from the Western Balkans to the Black Sea, but the Marmara Sea provides oxygen via an undercurrent. In addition, 60 percent of Turkey's fishing industry is in the Black Sea.
