What Are Ocean Dead Zones?
There is plenty of marine life under the depths of sea, but it is not the same everywhere. In this article I will tell you about dead zones, their formation, causes and effects. But do not confuse dead zones with the Dead Sea which we studied in a previous article. So lets find out about ocean dead zones Dead Zones are low-oxygen or oxygenless areas in oceans where marine life cannot be supported. The dead zones are not only devoid of fishes but also of any type of sea food. Today there are approximately 405 dead zones in the world today and many more are in the process of formation. Dead zones can be of any size, from few square kilometers to the largest of 70,000 square kilometers. Several human activities are leading to the formation of these dead zones. Dead zones are generally found near highly populated areas and even near coast lines. Dead zones are not just seen in oceans but many fresh water bodies too.
