Terrible data about dead seas on the oceans

Those are, causing a mass death of fish.

Sea creatures want to survive not only need water, but also have enough oxygen in the water. So in the oceans, there are areas of oxygen density that are just round numbers. They are called with a very similar name: the sea of ​​death, because the marine creature that came in here seemed to be sure of death.

Sea creatures died when entering the dead sea.

And according to a recent study, the total amount of oxygen-free water in the oceans has quadrupled compared to 50 years ago. Specifically, the oceans have lost about 2% more dissolved oxygen over the past half decade.

"Oxygen is an indispensable ingredient for life on the ocean. And oxygen depletion is one of the most serious phenomena, affecting the environment and people" - Dr. Denise Breiburgh - a home Oceanographic ecology at the Smithsonian Environmental Research Center commented.

This is the data given by experts from GO2NE (Global Oceanic Oxygen Network) - a research group under the auspices of the United Nations. According to research, and are two main reasons behind this phenomenon, and people are forced to find a way to solve it.

Algae poisoning explodes causing fish to die in mass.

" The effects of climate change and nutrient pollution have increased the number of deadly seas in the oceans and large waters. Here, the oxygen concentration is too low to support the live " - Dr. Vladimir Ryabinin, secretary of the International Oceanographic Association, where the shared GO2NE was formed.

Nutrient pollution is a concept that indicates the process of sewage and human waterways carrying too many nutrients, causing algae to explode, creating a " phenomenon " . Algae form and die, and the bacteria used to decompose them clean up oxygen in the water.

In addition, the process of global warming also makes it difficult for oxygen to dissolve into water. The more warm the sea is, the more oxygen escapes, and the catastrophe of mass destruction with marine life will occur.

Sea of ​​death will directly affect human industries.

In addition, because the dead waters cannot support life, marine life will escape. This seriously affects the biological distribution process.

But not yet, even in areas where the process of oxygen depletion is not too serious, the consequences are very unpredictable. Sea creatures will not die, but they grow more slowly, become smaller in size, and cannot reproduce.

Experts warn that the disappearance of oxygen in the oceans will directly affect humans.

"Entertainment, tourism, restaurants, hotels, even taxi services . will be badly damaged" - Dr. Lisa Levin, one of the study authors from the Institute of Oceanography Scripps said.

"This is a huge pressure on the oceans on the Earth. We have heard enough about the pollution of plastic garbage on the sea , " said Lyndsey Dodds, marine policy director at WWF International Fund for Nature . "Excessive fishing practices. Now there is one more problem that has not received proper attention, even though the consequences are very bad."

However, although the data is worrisome, experts are still very optimistic."This is a problem people can handle" - said Dr. Breitburg. "The prevention of climate change needs humanity, but only if the local authorities join hands is enough to temporarily handle the nutrient pollution".

The study is published in the journal Science.
