According to reports, on a coast in the United Kingdom recently, since a few weeks ago, there have been many corpses of marine life here, especially this week, and a large number of marine organisms have appeared at once, looking like tens of thousands, piled up on the coast into a hill, which makes the local residents feel very afraid.
Judging from the piled up carcasses of marine life, not only the carcasses of various shellfish and sea crabs, but also the large lobsters have also died in large quantities, in addition, a large amount of seagrass has also been washed to the shore, which also carries some dying marine life.
At present, the local authorities have stepped in to investigate and want to see what causes the death of a large number of marine organisms, and the current view is that it is either a large-scale marine pollution incident or related to the disease of animals in the ocean.
<h1 class="pgc-h-arrow-right" data-track="4" > so what causes a large number of marine life to die? </h1>
At present, in many seas around the world, the most likely to cause large-scale marine life deaths is the "red tide", for example, in July this year, the coastal area of Florida, the United States, there was a large-scale red tide, when more than 1,000 tons of dead fish were washed ashore, the scene is extremely spectacular.
In addition, in 2016, there was also a serious red tide off the coast of Chile, when it was also a large number of shellfish and marine mollusks, etc., which were washed ashore after a large number of deaths and piled up on the beach.
So, what is red tide? Simply put, it is an anomaly in the marine ecosystem, and when it occurs, the number of plankton in the ocean also increases, resulting in the emergence of harmful marine ecological phenomena.
In addition to the red tide, due to the different colors of plankton and bacteria, the red tide will also be divided into a variety of colors, as well as green, blue, brown, etc., of course, no matter which color of the red tide, it is extremely harmful.
So, how is the red tide formed? Speaking of which, this is mainly related to people's pollution of the ocean, when a large number of pollutants into the sea, it will lead to an increasing content of organic compounds in the ocean, so that the pollution problem of the ocean begins to become more and more serious.
Among the organic compounds, it is rich in a large number of nutrients, these nutrients for microorganisms in the ocean, plankton, are one of the most important food sources, so in the case of high nutrients in seawater, it will lead to the intake of a large number of nutrients of microorganisms, plankton, etc., began to multiply on a large scale, thus forming a red tide.
So how does red tide cause a large number of marine life to die? This is actually related to the lack of oxygen in seawater. When marine microorganisms, plankton, etc. multiply in large quantities, it will lead to a continuous decline in the oxygen content in the seawater, resulting in large-scale hypoxia of marine life, naturally, many marine organisms will die as a result, and eventually washed ashore by the seawater.
<h1 class="pgc-h-arrow-right" data-track="21" > so, is there any other cause besides red tide that can lead to mass death of marine life? </h1>
The answer is yes, taking the large-scale death of marine life in the United Kingdom this time, if it is caused by red tide, then the relevant media will not be unable to tell the reason when reporting, and the local researchers in the United Kingdom will not sample to investigate.
Therefore, this also means that this time there is a large-scale death of marine life in the United Kingdom, which is most likely unrelated to the red tide, so what other reasons besides the red tide will lead to the mass death of marine life?
The first is the emission of pollutants, such as the discharge of toxic substances, when pollutants enter the ocean, under the action of the greenhouse effect, it will accelerate the release and diffusion of pollutants, which will lead to a large number of plankton accelerated death, and lead to problems in the marine ecological chain, so that the upstream organisms of the ecological chain also die due to food shortages.
The second is the oil spill problem, some time ago, there was an oil spill in California, the United States, which also caused the death of tens of thousands of marine organisms. In addition, there will be a large number of higher marine organisms, as well as seabirds, etc., will also die, but at present, the large-scale death of marine life in the United Kingdom is not related to oil spills.
In addition, there is a certain infectious disease in the ocean, which has led to the death of a large number of marine organisms, which is also one of the reasons speculated by British researchers.
Overall, this time there is a large-scale death of marine life in the United Kingdom, one is related to unknown pollution, and the other is that it may be related to unknown marine biological infectious diseases, of course, the specific need for further laboratory analysis to get the answer.
Regardless of the outcome, it is clear that the large-scale death of marine life is not a good sign, it means that the local marine ecological environment has been seriously damaged, and this destruction is basically related to human beings, and human beings have to reflect on themselves!
