Recently, a large number of bizarre marine carcasses have been found in coastal areas in many parts of Japan, causing concern among local people and environmentalists.
From the fishermen who found a large whale carcass 10 to 15 meters long on the shore of Tottori Prefecture,
It is understood that the carcass of a large whale found by fishermen off the coast of Tottori Prefecture is suspected to be a Sai whale or a Bryde's whale, and the carcass has been floating at sea to rot and change color for a long time.
In December, Hokkaido's roughly one-kilometre coastline was covered with more than 1,100 tonnes of dead sardines and some mackerel carcasses, and it took the local government 18 days to clean up.
Immediately afterwards, the fishing port of Shima City, Mie Prefecture, was also buried by hundreds of tons of rotting and dead fish, emitting a foul smell.
Such a shocking scene has undoubtedly aroused concerns and questions about Japan's current marine ecological environment. Some fishermen suspect that the frequent short-term discovery of large numbers of dead fish may be a sign of changes in Japan's offshore ecosystem.
However, Japanese officials explained that the main cause of the fish kills was due to a lack of oxygen, and that there was no involvement in nuclear contamination such as the Fukushima nuclear power plant leak. However, given the persistence of a large number of bizarre fish deaths, it is inevitable that this explanation will be questioned.
So, is there some kind of marine ecological anomaly caused by deep-seated environmental changes that we have not yet understood? Perhaps this requires more in-depth and detailed investigation and analysis by the relevant Japanese authorities to restore the truth of the incident.
Coincidentally, a large number of dead fish carcasses also appeared in the waters of Xiuying District, Haikou City, Hainan Province in mainland China not long ago, and the preliminary investigation and analysis may be related to the recent eutrophication and hypoxia of seawater. It can be seen that the marine ecological environment is fragile and needs to be jointly cared for and maintained by all parties.
Historically, events such as the mass death of marine life have a long history.
Scientists speculate that some of them may be related to natural disasters such as asteroid impacts and volcanic eruptions.
Today, the main challenges facing the marine ecosystem come from human factors, such as overfishing, marine pollution, climate change, etc. It is imperative to protect the earth, the home on which it depends. Everyone should play their part.
Although mankind has made great strides in science and technology, it has never understood the mysteries of the natural world. We need to be humble and reverent, to understand and explore the world with an open and inclusive mind, and to live in harmony with nature. Only in this way can the earth's ecosystem develop sustainably and benignly, and future generations of mankind can share a green home.
