Well, it is a closed sea with its disadvantages but a beautiful body of water. The problem is that it is very polluted after 50 years of various and multiple spills during the dictatorship and the proletariat. The absence and / or inefficiency of treatment plants does not help. Overfishing makes it almost nothing and eating fish by the sea is to promote the balance of trade .... It's a shame because there are landscapes to fall and it is a unique site to preserve and save urgently.
One of the peculiarities of this sea is that it was first freshwater lake and all the water below 60 to 70 meters is soft and above salty. The absence of oxygen in the deep layers allows for unique preservation of the wrecks, which remained intact after more than 2000 years under water.
