A very large swath of marine green algae in the Yellow sea with a length of more than 410 square miles, stretches to the Chinese city of Qingdao and surrounded all of the local beaches.
These algae, it is not hazardous to health, but endanger the existence of the whole ecosystem, because you absorb very large amounts of oxygen, it is not leaving it to other marine flora and fauna.
Photos look absolutely certainly not cheerful, but local Chinese have become accustomed to this everyday phenomenon as it occurs for the third time in the last five years. Tsindao has experienced a serious invasion of algae in 2007, 2008 and 2010, which destroyed its water culture and brought a huge loss to flora and fauna.
In 2008, another influx of green algae threatened the Olympic games, which eventually was carried out quite successfully.
