Japan's seafood products have always been the income of many Japanese fishermen, but since Japan decided to discharge nuclear wastewater, not many people in Japan have dared to eat seafood products, because everyone is worried that Japan's nuclear wastewater discharge will affect the mutation of fish, and worry about infecting other things in the process of eating, so Japanese fishermen are also greatly affected.
Although Japan has been saying that the row or not depends on the situation, on December 12, Japan's Yomiuri Shimbun reported that there have been a large number of fish deaths in Japan's coastal waters, and we can clearly see that the surface of the sea is densely packed with fish carcasses, which are all over the sea level.
And this fish is similar to the carcasses of sardines and other fish, all over the width of the sea level, about 4000 meters in length, width of about 50-100 meters in the area, and this situation in Japan's Maritime Guard said that this situation is because in the vicinity of the sea where a large number of fish die, there is no news of ship sinking, which makes many people wonder, if there is no ship sinking and other reasons, why these fish will die in large numbers to cause this situation? Could it be that Japan discharged nuclear wastewater as a result of this? With these questions in mind, let's take a look at why.
In order to understand whether it is a problem of discharging wastewater, we must first look at the causes of the large number of fish deaths in the sea, and in general, the causes of fish deaths, there are the following 4 situations.
(1) Discharge of a variety of toxic wastewater, this is very well understood, in the past many factories in the production, will be discharged into the sea, resulting in biological death of the case, this wastewater can also be like nuclear wastewater these, if the nuclear wastewater drainage into the sea, it will also lead to the death of many organisms, resulting in such a problem.
(2) Oil spills lead to events, oil spills will also cause a large number of animal deaths, because in oil, contains a lot of toxic compounds, such as toluene, these toxic compounds leaked into the sea, will pollute the seawater algae and various mammals, once exposed to the phenomenon of death.
This is also why after a large number of Fish Carcasses in Japan appear in the sea, the relevant departments will report that there are no accidents nearby, and the reason is that it is worried that the oil ships or other toxic substances will cause the death of the fish after the accident.
(3) The impact of red tide causes disasters, in addition to the two situations mentioned above, there is also a situation in which the ocean often breaks out, that is, red tide, the primary condition caused by this red tide is the eutrophication of seawater, to put it bluntly, it is too much nitrogen, phosphorus and other nutrients.
Because of these nutrients too much, will cause changes in the color of the seawater, such as red and other colors, the most common is red, so the red tide is also known as the red tide, with the change of seawater, and then will affect the survival of fish, such as the occurrence of red tide, it is easy to cause fish suffocation and death, that is, hypoxia state, some fish mistakenly eat toxic algae, it will also cause a large number of fish deaths, so there will be a large number of fish deaths like Japan.
(4) Earthquakes cause accidents in submarine volcanoes, and the last possible situation is that the activity of seabed magma has caused such a situation, and I think everyone knows that there have been many earthquakes in Japan recently, although it is not so large, but the number of occurrences is too much.
Therefore, it is possible that the earthquake caused the eruption of magma on the seabed, which caused these fish in the sea to be burned to death by high temperatures, causing these fish to surface after death.
As we just said, when the red tide occurs, it will cause changes in the color of the ocean, but if you look at the photos from the relevant reports, there is no change in the ocean, and if it is an oil spill, then there is almost an accident in the vicinity, but in the Global Times report, Japan's Coast Guard also said that there was no news of a ship accident nearby.
If none of this is true, could it be that Japan's secret discharge of nuclear wastewater would cause the pollution of the oceans and cause a large number of fish deaths?
In fact, relatively speaking, this is not necessarily, because as we said above, in addition to factory pollution, there may be various reasons caused by seabed magma, to know that the current Japanese earthquakes have been frequent, although the earthquake level is not large, but overall, it is still too frequent, so this can not be excluded.
However, in general, the final result will definitely wait for the investigation of the relevant Japanese departments before we can learn the truth of the matter.
The above is the relevant content brought by xiaobian for everyone, how do you think about such a large number of deaths in Japan? Feel free to leave a message in the comments section below.
