21 July, IUCN.
Declared the Yangtze white sturgeon.
Extinction, they have lived on the earth for 200 million years, and they have disappeared in the long stream of history, and it is understood that the owner of the Yangtze white sturgeon "freshwater fish."
The title of "king", the main food is fish and shrimp in fresh water, etc., with a length of more than two meters and a weight of about 200 catties. The reason for the extinction of the Yangtze white sturgeon is also due to human aggression towards the natural environment.
The destruction of land reclamation has reduced the living space of the Yangtze white sturgeon. <>
Many years ago, in order to develop the economy and science and technology, in vain to other species of creatures on the earth, and constantly shrink their living space, their habitats were seriously damaged, the oxygen content of rivers declined, the difficulty of survival and reproduction increased, and the number of species declined sharply. <>
After the extinction of the Yangtze white sturgeon, biodiversity was reduced.
On the bright side, the extinction of the Yangtze white sturgeon has hindered the development of the country's biodiversity, which is not conducive to the country's biological research, and the serious damage to the ecological environment may threaten freshwater fish, and other fish may reproduce rapidly because of the extinction of the Yangtze white sturgeon without the threat of survival, which is not conducive to the development of the biological chain of freshwater organisms. <>
The demise of the Yangtze sturgeon is a warning to human beings to speed up the protection of nature, not to let the environment be destroyed, to maintain biodiversity, so that the organisms in every place can grow and develop in their own fields and continue to thrive in their own living space, and human beings, as the top of the biological chain, should also reflect, minimize behaviors that are not conducive to the ecological environment, and include the protection of the ecological environment in the constitution, so that the maintenance of the ecological environment is engraved in the hearts of every people.

The decline in oxygen levels in rivers has made it more difficult to survive and reproduce, and the population has declined sharply, and the extinction of the Yangtze white sturgeon is the best example of protecting the ecological environment.

According to the latest news reports, the white sturgeon, an endemic species of the Yangtze River, has become extinct, and it is a first-class protected wild animal in China. The extinction of the white sturgeon has destroyed the ecological balance of the Yangtze River basin to a certain extent.

Hello dear and happy to answer for you. What are the ecological impacts of the extinction of the Yangtze sturgeon: The Yangtze sturgeon was officially declared extinct and lived for about 200 million years, and the extinction of some species may have the same impact on human life to a certain extent, because some species may have some unknown impacts on the ecosystem after the extinction.
The extinction of some species may bring about the extinction of genes, because after all, human beings have to study genes in the history of development, and the extinction of any species may affect human research on genes, and the disappearance and extinction of species may be due to the impact of human activities, so the disappearance of these species may also affect the development of some things to a certain extent, so protecting these species is also protecting human beings. Hope mine is helpful to you! Don't forget to give it a thumbs up!
I wish you a happy life, peace and joy!

The Yangtze white sturgeon was officially declared extinct, which is a species endemic to the Yangtze River, which has survived for many years, and the extinction of the species actually reflects the serious damage to biodiversity, which is very large, so that biodiversity can allow everyone to survive and develop.
Biological diversity provides food, fiber, medicine, etc. for human beings, so to truly maintain biodiversity, then cherry blossoms to maintain species diversity, the extinction of the white sturgeon is actually because the awareness of ecological protection is not strong, the intensity is not enough, because these white sturgeon have no place to produce value, they have no spawning ridge, and at the same time can not be artificially cultivated, they are gradually going extinct.
Human beings are constantly encroaching on the environment, but because the construction of the Yangtze River water conservancy project has also hindered their history and growth, which is equivalent to habitat destruction, sewage, shipping, construction, these activities will lead to water pollution, even if it is a white bear, but because they are timid by nature, and at the same time have a very strong character, refuse to eat, it is difficult to survive.
Their extinction actually sounded the alarm for everyone, everyone should abide by the law of survival limits, human beings want to survive, nature is the most basic condition, so the protection of the ecological environment is to protect productivity, while protecting biodiversity, in fact, it is in disguised protection of themselves, it is because of people's overfishing that the fish in the Yangtze River has slowly shrunk, and even the cherry blossom is a sharp decline, and the protection of the ecology of the Yangtze River is an urgent matter. This also has a great impact on species diversity, not only to save these creatures, but also to save humanity itself.
Species diversity, on the one hand, is the degree of ecological species distribution, species diversity is actually an indicator to measure the richness of biological resources in a region, the more types of these organisms, the more varied, then the better for the good operation of the earth.

Human behavior is overly intrusive.
In fact, sometimes the extinction of natural species is more related to the excessive interference of human behavior, and the main reason for the extinction of the endemic species of the Yangtze River in China is because the construction of dams has cut off the migration route of the white sturgeon, which will have a very great impact on the habits and life of the white sturgeon to a certain extent, and they cannot quickly adapt to the changes in the environment, so they will slowly go extinct. Although this problem was also taken into account in the process of dam construction, and fishing channels were built next to it, unlike humans, they did not have too much will to clearly design the trajectory of the dam, and the closure was still related to our excessive transformation.

The white sturgeon is a fish from the Cretaceous period of the Mesozoic Era to the present. Being declared extinct indicates that this biological chain has been affected and the inheritance of the species has been broken. The impact is very large.

The Yangtze white sturgeon is a small part of a certain "ring" of the food chain, and without the Yangtze white sturgeon, it will not directly damage the "ring" and break the entire food chain, so ordinary people will not be affected in a short time. Rakai.
Mine is also Lenovo G480, that's because you use the battery maintenance mode, which can only be charged to sixty percent, which is good for the battery, if you want to rush to 100 percent. Let's change the battery mode to full mode. However, if you often use power supply and less battery power, use maintenance mode, so that the battery life is long. >>>More
