What are the animals that have been rescued but are still extinct

There are more than 794 species of wild animals in the world that are endangered due to the lack of due environmental protection More than 300 species of plants in 76 families are endangered The above information is only what humans know at present, and it is not known how many unknown species are disappearing. Did you know that the number of animal species on Earth is decreasing dramatically, one after the other, one after the other. Organisms on Earth are naturally interdependent as food chains.

Some people ask how long if only humans are left in this world, how long can humans last? Consider the alarming accounts of recent animal extinctions: the dodo (India, 1781), the blue wildie (South Africa, 1799), the Marion tortoise (Tongue Ser, 1800), the great puffin (Atlantic, 1844), the European wild horse (Europe, 1876), the spotted donkey (Asia, 1883), the white-rumped langur (China, 1893), the passenger pigeon (North America, 1914), the Florida monkey (North America, 1917), the Carolina parrot (North America, 1918), the Chinese rhinoceros (China, 1922), Caucasian Bison (Europe, 1925), Bali Tiger (Indonesia, 1937), Red Duck (India, 1942), Przewalski's Horse (China, 1947), Thylacine (Australia, 1948), Hooded Shelduck (Asia, 1964), Javan Tiger (Indonesia, 1972).

A golden frog in the United States, the Japanese wolf, a subspecies of tortoise (there was only one left when it was discovered, because it could not see its companions, it lost its sexual function, and it was impossible to even mate it with genetically similar tortoises). Most of them were rescued by humans too late, and the earlier ones were like giant pandas, dolphins, and cetaceans, all because of human overhunting.

Each organism has its own specific position and role in the ecosystem of nature, and they live in interdependent and mutually restrictive communities, maintaining a delicate ecological balance. If a creature disappears from the earth, it will have a chain reaction, even bringing unintended consequences, and even endangering the survival of human beings themselves. For example, spiders are a type of arthropod with many species, and this ugly-looking small animal mostly feeds on insects.

According to the data, spiders eat more insects (mostly pests) each year than the entire population of the United Kingdom in the United Kingdom alone, so if spiders disappear from the earth, won't the harmful insects on the earth be overflowing?

Endangered animals are experimental materials for scientific research and play an important role in zoology, evolution, ecology, genetics, modern medicine, bionics and other disciplines. For example, the vast majority of the tens of thousands of cynomolgus monkeys and macaques domesticated and bred in China are used as experimental animals or to produce vaccines against diseases. Scientific research institutes, colleges and universities, zoos and museums collect, display or exhibit specimens of endangered animals, and play an important role in scientific research and teaching, publicity and education, and law enforcement activities.

Biodiversity is an important part of the natural environment and a valuable natural resource, which has great economic value, but also inestimable environmental, scientific and spiritual value.

One of the most important reasons for protecting wildlife is because of its potential value in ecosystems, which have been predators or carry genes to overcome certain hazards in the billions of years of biological evolution, and once these genetic resources are lost, humans will become more vulnerable in the ecosystem, and it will be difficult to overcome biological disasters in the event of a biological disaster.

Summary. Hello dear, it is a pleasure to answer for you : why are they endangered animals, + what do people do to save their dear, the answer is:

1. Establish nature reserves: The fundamental measure to protect endangered animals is to protect their habitats, and the main way to protect habitats is to establish nature reserves, through the establishment of nature reserves, not only can protect endangered animals and their habitats, but also other kinds of wild animals and plants can be well protected. 2. Carry out domestication and breeding

Domestication and breeding is an effective way to protect, develop and rationally utilize endangered animal resources. The development of artificially propagated populations can not only prevent or delay the extinction of relevant species, but also meet the production and living needs of the people, reduce the hunting pressure on wild populations, and provide seed sources for the implementation of reintroduction projects to rebuild or expand the wild populations of relevant species. 3. Implement the reintroduction project

The reintroduction of wild populations is an important means of protecting and expanding the wild populations of critically endangered animals, and the so-called reintroduction is in areas where a species was once distributed but is now extinct. Dear, I hope mine can help you

Why they became endangered animals, + what people did to save them.

Hello, dear, I am happy to answer for you: why did they become endangered animals, + what measures did people take to save their relatives, the answer is: 1. Establish a nature reserve:

The fundamental measure to protect endangered animals is to protect their habitats, and the main way to protect habitats is to establish nature reserves, through the establishment of nature reserves, not only can protect endangered animals and their habitats, but also make other kinds of wild animals and old plants can be well protected. 2. Carry out domestication and breeding: domestication and breeding is an effective way to protect, develop and rationally utilize endangered animal resources.

The development of artificially propagated populations can not only prevent or delay the extinction of relevant species, but also meet the production and living needs of the people, reduce the hunting pressure on wild populations, and provide seed sources for the implementation of reintroduction projects, and rebuild or expand the wild populations of relevant species. 3. Implement the reintroduction project: the development and expansion of the wild population reintroduction project is an important means to protect and expand the wild population of critically endangered animals, the so-called reintroduction, that is, in the area where a species was once distributed but is now extinct.

Dear, I hope mine can help you

Hello, dear. Resource monitoring and scientific research are necessary steps for the conservation and sustainable use of endangered animals, and through resource monitoring, we can understand the growth and decline of wild populations of endangered animals and the changes in distribution areas. It provides a scientific basis for the national policy on the management and utilization of the protection of tall oak.

At present, the relevant departments are studying the establishment of a national resource monitoring system. Dear, I hope mine can help you
