What are the main reasons for the extinction of the white sturgeon? Looking back at the extinction o

The Yangtze River white sturgeon is a species unique to the Yangtze River in China, and it is also a first-class protected animal in China, which has survived on the earth for about 100 million years and has a long history. However, on July 21, the relevant departments officially declared the Yangtze River white sturgeon extinct, which also shows that in China's Yangtze River basin, there is no longer a Yangtze River white sturgeon, which is a very sad thing for human beings, which means that the number of animal species living on the earth has decreased. There are two main reasons for the extinction of the Yangtze sturgeon, the first is overfishing, and the other is the impact of the living environment on the Yangtze sturgeon.

As we all know, the size of the Yangtze white sturgeon is very large, and the largest can even grow to seven or eight meters long, which is precisely because of its huge size and delicious taste, so that the Yangtze white sturgeon is favored by many consumers. Before the state issued a clear ban on it, many fishermen would catch a large number of Yangtze white sturgeon in order to obtain more economic benefits to cater to consumers. Therefore, overfishing by humans is one of the main reasons for the extinction of the Yangtze sturgeon.

With the continuous development of society, many dams have been built in the Yangtze River basin, and the emergence of these dams has seriously blocked the migration of the Yangtze white sturgeon, which has caused a certain degree of impact on their living environment. In addition, the sand and gravel mining that has been carried out by humans has also caused damage to the habitat of the Yangtze white sturgeon, and the lack of habitat has led to the inability of them to spawn and reproduce normally, and the number will naturally become smaller and smaller, and eventually lead to extinction.

There are also reasons for environmental pollution, the increase in population along the Yangtze River will inevitably cause pollution and damage to the water quality of the Yangtze River basin, which is also extremely unfavorable to the survival of the Yangtze River white sturgeon. Therefore, at present, if human beings still want to make amends, they must strengthen their awareness of the protection of the ecological environment and strictly prohibit the illegal activities of fishing wild animals.

I think the main reasons include the overcompensation of human beings for a long time, as well as the deterioration of the local water environment and people's pollution of the environment; If we can review the extinction of the white sturgeon, we can certainly make amends.

Including human interference, changes in the environment, changes in temperature, changes in water quality. Be sure to protect the environment, do not litter, do not emit a lot of harmful gases.

The sea level has dropped mainly due to the unclean water quality and the destruction of the ecological environment in the Yangtze River basin. I feel like we can protect the environment and minimize the extinction of other animals.

Therefore, after the extinction of the Yangtze River white sturgeon, many people feel very sorry, so the extinction of the Yangtze River white sturgeon is actually a lesson, there are many other endangered creatures in the world, these creatures need human protection, human beings must establish the idea of harmony between man and nature. At the same time of economic development, it is also necessary to protect the habitat of animals, strive for the survival of animals, and strive for the safe survival of endangered animals.

If it is really extinct, then we have no way to make up for it, but to protect the creatures that are still not extinct.

We can protect the marine environment, avoid fishing, and don't throw garbage at sea, so that some people don't come to play.

If human beings still want to make amends, they must strengthen their awareness of the protection of the ecological environment and strictly prohibit the illegal activities of fishing wild animals.

Hello, happy with your question.

Causes of the extinction of the Yangtze sturgeon.

Water pollution**: Water pollution is one of the most worrisome problems, affecting the habitat of the Yangtze sturgeon and hindering its normal reproduction.

Fishery activities**: Fishery sourcing activities are also an important reason, which can lead to the fishing of other species in the Yangtze River, and the probability of catching or remaining in the Yangtze white sturgeon should not be underestimated.

Riverbed destruction**: Riverbed destruction is also an important factor, as it destroys the habitat of the Yangtze sturgeon, thus depriving them of a place to live.

Fry introduction**: The Yangtze sturgeon is also affected by the introduction of fry, which competes with the Yangtze sturgeon for food, causing damage to the Yangtze eggplant.

Early Wild Nalitre Animal Conservation**: Early wildlife conservation was also a cause for its extinction, as wildlife conservation technology was relatively backward at that time, which could not effectively resist the hazards of the external environment, which led to the extinction of the Yangtze white sturgeon.

In short, attention must be paid to avoid the recurrence of such extinction events. I hope that everyone can reduce the damage to the natural environment and strive to realize the ideal of harmonious coexistence between man and nature.

In the past, many people used to catch a large number of Yangtze white sturgeons in the Yangtze River for their own interests, and there was no fishing ban on the Yangtze River in our country before. As time passed, more and more people around the Yangtze River basin began to hunt for more profits, which is one of the reasons for the extinction of the Yangtze sturgeon. <>

If a species wants to survive better, it must have a very good habitat, and only then can it reproduce better. However, many dams have been built in the Yangtze River basin, and these dams have also blocked the migration route of the Yangtze sturgeon. In addition, human beings have also carried out continuous sand and gravel mining in the Yangtze River basin, which has also destroyed the spawning grounds of the Yangtze white sturgeon, and it is precisely because of these two reasons that the habitat of the Yangtze white sturgeon has been completely lost, and finally slowly went extinct.

Although the water quality of the Yangtze River has gradually improved after the treatment in recent years, the water quality of the Yangtze River is relatively poor due to the impact of urban domestic sewage and industrial wastewater in the past, which also directly affects the survival of the Yangtze white sturgeon. You must know that the requirements for water quality of the Yangtze white sturgeon are very high. <>

In recent years, there have been more and more extreme weather, either the weather will be particularly cold or the weather will be particularly hot, and this has had a very big impact on the survival of the Yangtze white sturgeon. When extreme weather occurs, the water temperature in the Yangtze River will naturally be affected, and it is precisely because of this hot and cold water temperature that it directly leads to the extinction of the Yangtze white sturgeon. <>

In addition to the above reasons, there are actually many reasons, such as the Yangtze River itself is a waterway, so some Yangtze sturgeon were also killed by the propellers of ships.

According to reports, it is mainly due to the influence of human factors. The damming of the Yangtze River blocked the return channel of the white sturgeon, preventing it from returning to its original spawning grounds to reproduce, and they were unable to adapt to the new environment quickly, thus affecting the reproduction of the entire species. At the same time, pollution and overfishing have led to an overall decline in the number of fish in the Yangtze River, and the carnivorous white sturgeon has naturally encountered food shortages.

There are too many people who eat, so it is too late to produce at this time, which has caused such a problem, which is particularly serious.

The destruction of the environment has led to the fact that the white sturgeon has no place to live, and finally has to become extinct.
