Pollution from household waste in Turkey has caused Sea Snot Plague
 

[A thick layer of "sea snot" thought to be
the largest on record has hit the Turkish coast,
endangering marine life and fishing trade.
The marine mucilage is a slimy layer
of grey sludge that forms when algae
is overloaded with nutrients as a result
of hot weather and water pollution.
It was first found in Turkey in 2007 but has
also been discovered in the
Aegean Sea near Greece.
Turkey's recent outbreak along its
Sea of Marmara coast is believed to be the
biggest in history and is causing chaos
for local communities.]

[The 'sea snot' - officially known as
marine mucilage - suffocates wildlife,
wrecks havoc with fishing nets, and can clog
the propellers of other boats which sail through it]
