There are signs of a resurgence of extinct species, what is causing this phenomenon?

Now there are some creatures that are basically all extinct, and it seems that they are appearing in the field of vision one after another, what does this prove? Proving that the Earth's environment is gradually changing is not necessarily a good sign, because adapting to the survival of endangered species means becoming less and less suitable for human existence. In a sense, human beings are at odds with the requirements of the living environment of these endangered or declared extinct species.

The increasing range of human activities has affected the natural environment more and more, resulting in the loss of living space for some organisms, and then the difficulty of reproduction and gradual extinction, which is a normal process of gradual disappearance of species in nature. But some extinct species seem to be gradually appearing, which proves that the natural environment is gradually changing to adapt to the existence of those organisms, I don't know if you have carefully observed, in recent years, the frequency of natural disasters seems to be much higher than before, **, volcanic eruptions, typhoons and the like are more numerous, and the frequency of drought and flood disasters seems to be higher, which is not a good sign. <>

Because this means that the living environment of human beings themselves may be more harsh, and the survival of certain creatures is getting easier and easier, and the survival of human beings will become more and more difficult. Because how is it possible to say that people can live in harmony with nature, and that humans can live well, and those animals are not affected? Different species require different reproductive environments, and sometimes some species prefer the kind of spoiling and humid environment, can humans live in this environment?

Some species are in the forest, and in order to cut down timber and reverse industry, human beings must cut down forests, build flat land, and build human settlements, isn't this all conflict? <>

The increasing number of extinct species in these cases is not because the natural environment has become better, not because people have achieved better results in protecting nature in recent years, but because nature itself is changing. The living environment of human beings is getting worse and worse. Whether it is the emergence of this contagious virus or the frequency of volcanic eruptions, droughts, and floods, it makes it more difficult for human beings to survive.

When the last individual of a species dies, the species meets the definition of "extinct". However, in practice, it is difficult to determine whether the dead individual is the last individual of the species. Species that have been extinct for too long lack relevant research and research, and by chance they are discovered by someone who knows the species, and there is a "reappearance of extinct species".

First of all, it may come from competition between organisms, survival of the fittest, and then it may be due to natural disasters, such as floods, **.

Another cause of extinction comes from competition between organisms, such as predation between predators, or diseases of the genes within organisms.

We often hear the word extinction in our daily lives, and in recent years, more and more species have gradually disappeared from the world. According to research, there was an unprecedented catastrophe 66 million years ago, which directly wiped out 75% of the world's life, and after this catastrophe, many species disappeared in just 1,000 years, and dinosaurs were among the victims. The extinction of most species is either a natural disaster or a man-made disaster.

It takes a long time for a new species to be born, and it takes a lot of time to create a new species, but it is too difficult for now. And this also has a certain relationship with the life span of human beings, many species need to evolve and evolve gradually in the process of reproduction, biological evolution is a process, not to say that it suddenly mutates at a certain time, so this process is very slow, compared to the life span of humans, it is difficult to observe the changes in these animals. For example, the polar bear is the evolution of the brown bear, so the birth of a new species is not something that can be seen in an instant, so it is rare to see the birth of a new species.

There are many reasons for this extinction, one is natural and the other is man-made. If it is a natural cause, in the long historical process of organisms, some species will gradually evolve in order to adapt to the environment, and some can not adapt to the new environment will be reduced in number or even extinct. However, there are some causes of species extinction due to human destruction, and now human activities have destroyed the living environment of many organisms, and many human beings will hunt other species for different reasons, resulting in species extinction.

It is very easy to destroy a species, but it is very difficult to want to be affected by a species, it is very easy for nature and human beings to destroy an animal, but if you want to wait for the birth of a new species, it takes a very long process, so if human beings want to protect animals, they must not only act themselves, but also call on the people around them to act together and call for the protection of animals.

This is because the time of extinction is not the same as the birth of a new species, and the time that occurs after the extinction of a species is particularly short, and the birth of a new species takes a long time.

Because species extinction is easy, the birth of new species requires a very harsh birth ring, and the birth of new species takes a long time, but the life span of human beings is relatively short.
