Attempts to clean up that look awkward at first given the extent of the pollution.
Turkey is trying to take action against the massive pollution in the Marmara Sea.
A thick layer of organic slime covers the water along the coast in ports and on beaches.
The Sea of Marmara is located south of the metropolis of Istanbul, between the Black Sea and the Greek Aegean Sea.
According to the Turkish Environment Minister, a total of 43 boats are busy cleaning the water surface, laying barriers and removing the slime.
Around 1000 people are in action.

“This is entirely because our sewer systems are inadequate. We just can't do biological treatment. The population is growing. The Marmara region has a large population. The sea defends itself. "
The so-called "Seerotz" threatens mussels and corals on the sea floor and also the fishing industry, as it makes the fishing nets unusable. The green-gray, viscous mass is the result of a strong increase in phytoplankton, which in turn is due to high temperatures and wastewater problems. The effects on underwater life are already dramatic: instead of the original 170, only about 25 species of fish are currently at home in the Marmara Sea. And there is also a risk of economic consequences - because tourists are likely to find the slime carpet in the water rather unattractive.
