Oceanic dead zones are a fairly recent problem that has been discovered during the 1970s. They are hypoxic areas in the world's oceans and large lakes, which result in large inhabitable zones. These can range in size from a square kilometer to 70,000 square kilometers. An increasing number of oceanic dead zones in recent years merits an increasing concern to prevent the creation of more dead zones and to reduce the sizes of current ones.
