A new infographic has been released recently on Oceanic dead zones, hypoxic (or low-oxygen) areas in the world oceans and large lakes are caused by excessive nutrient pollution from human activities and other factors that deplete the oxygen required to sustain life.
Distance Learning, a website that provides everyone with the latest information about distance learning degrees, schools and news. It was formed in 1999, and since then, it has been helping students and educators find their niche in the world. For those dedicated to environmental issues, oceanic dead zones is important.
According to the infograph, the earth currently has more than 500 oceanic dead zones, with the count doubling every decade. A single dead zone may cover tens of thousands of square miles. They can occur naturally, but scientists are concerned about the amount of dead zones caused by human activity.
Hypoxic conditions are caused by eutrophication, agricultural run-offs or interfaces, such as well being dumped into rivers, and vehicular sewage and industrial emissions near a body of water. The New York Times reported on the subject, and said that global proliferation of dead zones, once mainly a problem of the developed world, has been fueled by industrialization all over the world, changing eating habits and population growth, which has led to more fertilizer use and more waste in the world’s watersheds.
Distance Learning also added several great facts about dead zones, in order to educate people on the issue. There are an estimated 530 aquatic dead zones including 166 in the United States’ waters alone, all amounting to 95,000 square miles. Unfortunately, 1.3 million metric tons of fish food each year in the Baltic Sea are lost as a result of dead zones, causing even further harm to aquatic life.
There are four types of Hypoxia in water. The first is permanent hypoxia, meaning that oxygen rarely rises about 2 milligrams per liter, and these usually occur naturally. The second type of hypoxia is temporary, which exists for hours or days, but generally gets the oxygen back to sustain life. Seasonal hypoxia occurs every year, but only during warm seasons. Generally, fish and other aquatic life will migrate, or like trees, die and rebirth. Lastly, Diel Cycling hypoxia occurs in warm nights and only at night time.
