What caused the extinction of the species of the previous earth.
-
According to the news, more than 10,000 species in the world are at risk of extinction, and for some endangered species, China has mainly adopted the following protection measures:
Establishment of protected areas in forests. The protection of endangered animals is not to keep them in captivity, but to establish a nature reserve in the area where they live, and in this protected area, it is necessary to deny entry to unrelated people to avoid threatening these endangered animals. It is also important to understand the habits of endangered animals and their diets.
For example, the current antelope, the golden snub-nosed monkey.
Or bison. etc have been well protected.
In the case of conditions,Artificial breeding of endangered animals can be used。Some endangered animals can only survive in the wild, and once the bacteria are raised, it will affect their living habits and accelerate the rate of extinction. However, there are some species that can be bred in captivity for artificial breeding, for example, China's giant panda breeding base is the care of giant pandas and artificial intervention in breeding, so that giant pandas get rid of the list of endangered animals.
Related species can be introduced from other regions. For example, antelope and bison are social animals, and if they are only a single species, they are basically in danger of extinction, so they can be introduced from other regions to keep them living in a group and establish a new survival tribe. Many of our conservation measures use this method, and there are many successful cases, the most typical of which is the pangolin.
Scientific research and monitoring of endangered animals. Extinct animals often have patterns, and researchers need to find patterns and stop them through research to understand how these species change. Finally, the risk of extinction of the species is eliminated through human intervention.
In general, no matter which species has the right to live on earth, human beings should not interfere too much with the survival of species, but if there is a species at risk of extinction, it can lend a helping hand if necessary.

Biodiversity is evolved over thousands of years, is the material basis for human survival, is the wealth of human reproduction, it provides a lot of industrial and agricultural raw materials, and the protection of biodiversity is to protect the survival and development of human beings. <>
As we all know, with the acceleration of urbanization, sewage discharge, indiscriminate logging, and the needs of economic development, biodiversity has been seriously damaged, especially in the early stage, various natural disasters occur frequently, making the problem of biodiversity increasingly serious. In this severe form, first of all, China attaches great importance to the conservation of biodiversity, the conservation of biodiversity as an important part of the construction of ecological civilization, and has also achieved certain results, China has also joined the Convention on the International Convention on Endangered Species of Wild Fauna and Flora, China firmly fulfills its obligations under the Convention, and actively promotes the implementation of the Convention, 90% of China's vegetation types and terrestrial ecosystems, 65% of higher plant communities, and 85% of key protected wild animal populations have been effectively protected. Make a greater contribution to the conservation of endangered animals.
Then we have established habitats for endangered animals in major regions, in order to better protect endangered animals, the country has also carried out a large number of afforestation, which can greatly increase the coverage of the earth, only by protecting the earth's vegetation, it is more likely to prevent the deterioration of the earth's environment, the problem of global warming, can make more endangered animals have a home. China has established botanical gardens, wildlife rescue and breeding bases, and germplasm resources to allow more animals to have a place to live. At present, tens of thousands of endangered animal species have been saved in our country.
In the face of unprecedented challenges in global natural environment governance, only the international community can jointly promote the construction of a beautiful world where humans, nature, and animals coexist in harmony with each other. <>

For example, returning farmland to forests to ensure the living space of animals, such as formulating strict laws and regulations on the killing of wild animals, and for example, the state has also stepped up publicity efforts to make everyone aware of animal protection.

The cause of endangerment and extinction of wild animals and plants is environmental pollution, destruction of vegetation, and indiscriminate hunting.
With the development of human beings, the population has increased dramatically, the area of concentrated human activities has been expanding, large-scale deforestation, indiscriminate logging, overgrazing, unreasonable reclamation (land reclamation, wetland development, etc.), environmental pollution has made the environment uncomfortable and the survival of organisms has destroyed the habitat of organisms, making the living environment of organisms smaller and smaller, resulting in fewer and fewer biological species.
In addition, indiscriminate hunting, poaching, etc., have also reduced the number of biological species, and these reasons are mainly caused by human activities. Therefore, the main reason for the endangerment and extinction of wild animals is the excessive hunting and logging of wild animal and plant resources by humans, and the pollution and destruction of the habitat environment.
The significance of protecting endangered species
1. Maintain ecological balance: Each species is an important member of the ecosystem, and through the relationship of the food chain, species play an interdependent and mutually restraining role. When there is a problem at one point in the food chain, the balance of the entire ecosystem is seriously affected.
2. Ensure the normal development of scientific research and educational activities: Endangered animals are the experimental materials for scientific research, and play an important role in the fields of zoology, evolution, ecology, genetics, modern ear leakage medicine, bionics and other disciplines.
3. Promote economic development and meet the needs of people's lives: The vast majority of endangered animals have high economic value or ornamental value.

The main cause of the endangerment and extinction of wild animals and plants is human activities.
Human activities such as urbanization, agricultural development, and mineral exploitation have destroyed the habitats of wild animals and plants, hunted wild animals and plundered plants, and affected the survival and development of wild animals and plants to varying degrees. These main reasons are explained in more detail below.
1.Habitat destruction
With the increase in population and demand, humans have built a large number of residential areas, commercial areas, roads, railways, reservoirs, dams and other infrastructure, which need to occupy the habitat of wild animals and plants, resulting in a sharp decline in the number of wild animals and plants.
2.Illegal hunting and smuggling**
Wildlife smuggling** is very common worldwide. In many countries, smugglers hunt and sell products from wild animals, such as fur, bones, horns, teeth, rare medicinal herbs, etc., further exacerbating the decline in the population of already endangered species.
3.Lust continues
A large part of the reason why many wild animals and plants hunt is due to the pursuit of various aspects of human beings. For example, in order to obtain animal fur, bones, horns, etc., to make fashionable clothes and hats, traditional Chinese medicinal materials and other products. It can be seen that human desires have also accelerated the extinction of wild animals and plants to a large extent.
4.Industrial pollution
In many industrialized and urbanized areas, a large amount of wastewater, waste gas, and solid waste have caused serious damage to the ecological environment and the physical space of wildlife living space, and the scope and depth of the damage are conceivable.
5.Global warming
Global warming has led to an increase in extreme weather events, with waterlogging, droughts, and forest fires all challenging the survival of wildlife. Global warming is likely to further exacerbate the problems of forest land return and loss of grazing rights, thereby causing the decline and even extinction of wild animals and plants to a large extent.
To sum up, the main reason for the endangerment and extinction of wild animals and plants is the encroachment of human beings on the environment and illegal activities of wild animals and plants, so we must be aware that protecting the environment can make all living things coexist better on this earth.

The main reasons for the endangerment and extinction of wild animals and plants are the over-hunting of wild animals and plants, and the pollution and alteration of their habitats.
As important ecological elements on the earth, wild animals and plants assume many ecological functions, which are of great significance for maintaining ecological stability and human access to ecological services. However, in recent years, with the acceleration of human economic and social development and the rapid growth of population, the living environment of wild animals and plants has been seriously threatened, resulting in them facing the risk of endangerment and extinction.
Overhunting of wildlife by humans is a major cause of their endangerment and extinction. In some areas, due to excessive human hunting activities, the number of rare animals such as elephants, tigers, and other rare animals has decreased sharply, and extremely rare and even went extinct. The illegal targeting of some wild bird tracks, plants and other plant resources has also brought a great threat to their survival, causing their numbers to shrink.
Pollution and alteration of wildlife habitats is another cause of their endangerment and extinction. The over-exploitation and pollution of the natural environment and resources, deforestation and accelerated urbanization have led to the reduction of wildlife habitats and serious damage to the ecological environment. Plants and animals have lost their habitat and food**, and their populations are rapidly declining or even extinct.
Measures for effective wildlife conservation:
1. Strengthening legal protection is the basic way to protect wild animals and plants.
**Stricter laws and regulations should be introduced to clearly stipulate the protection of wild animals and plants, and severe penalties should be imposed for violations of legal protection. At the same time, there is a need to increase public awareness and understanding of these legal protections so that more people can participate in wildlife conservation.
2. Promoting sustainable use is also an important tool.
For example, the development of sustainable tourism, agriculture, etc., so that local residents can obtain economic benefits from wild animals and plants, promote the development of local communities, and at the same time protect the habitat and resources of wild animals and plants, so as to achieve the purpose of combining conservation and utilization.
3. Strengthen regulatory law enforcement.
Wildlife protection work needs to be carried out by professional institutions and personnel, and it is necessary to strengthen supervision and law enforcement, formulate effective protection plans, and increase the crackdown on illegal wildlife activities, illegal hunting, and forest logging. Promote environmental protection knowledge, strengthen education and publicity for all sectors of society, and let more people understand the importance of wildlife protection.

The earliest human direct evidence to study the origins of humans comes from fossils. Anthropologists use the method of comparative anatomy to study various fossils of ancient apes and humans, determine their relative and absolute ages, so as to determine the age of human fossils, and roughly divide the evolutionary history of humans into several stages. Geneticists use biochemical and molecular biology methods to study the size and rate of mutation of proteins and deoxyribonucleic acid (DNA) between modern humans, various apes and other higher primates to calculate their respective origins and differentiation ages. >>>More
Anthropoids Scientists Discover Earliest Human Ancestors A French team found fossilized bones and teeth of ancient humans in Kenya last year, and after research, scientists found that these may be the earliest ancestral remains ever discovered. Researchers have shown the fossils to the world, pointing out that they are older than Lucy, an ancient human fossil found earlier, and that they may be more than twice as old as Lucy. This discovery will add more topics to the already fierce debate over the origins of mankind. >>>More
