"Sea snot" in Turkey expands to Black Sea: media (2)

Aerial photo taken on June 6, 2021 shows Mucilage, also known as "sea snot" in the Marmara Sea in Istanbul, Turkey. According to local press reports, the sea snot, which has started from the country's biggest city Istanbul, spread to several other provinces along the coast of the Marmara Sea and the northern Aegean Sea. The substance, which seriously threatens the environment and underwater life, now covered a large part of the Marmara Sea, forcing the government to take urgent action that will be launched on Tuesday in Istanbul.
