There are a lot of them.

1.Northern white rhinoceros (Sumatran rhinocerous).

Congo's Garamba National Park is home to fewer than 25 of the world's remaining northern white rhinos, which are on the verge of disappearing from the planet entirely.

Located on the border with the Democratic Republic of the Congo, the Guaramba National Park was originally established with the intention of applying the park to become a World Natural Heritage Site, so the builders spared no effort to enclose a large area of grassland and forests. Guaramba National Park is home to many of the world's rarest animals, such as jungle elephants, bison, and chimpanzees, among others. Of course, the most precious animals are the northern white sky rhinoceros, which numbers less than 25.

There is a big genetic difference between the northern white rhino and the white rhinoceros in southern Africa, they were once bred in large numbers in Uganda, but gradually disappeared due to the neglect of protection in the local ** Douzhen. In the Guaramba National Park, their numbers reached 35 in the late eighties, 30 in April 2003, six were killed, four were newly born, and last month, two more were hunted, while nearly 1,000 elephants were killed.

Utilization of cat's claw vine.

Cat's claw vine is widely used as a folk medicine for inflammation, stomach ulcers, rheumatism, tumors, diarrhea, and contraception. For centuries, hermologists in Peru and other Latin American countries have used cat's claw vine for all kinds of ailments. In 1991, researchers discovered that cat's claw vine contains natural anti-inflammatory factors, confirming its arthritic efficacy.

Recent studies have also found that cat's claw vine can enhance immune function and potentially help prolong the life of AIDS patients. The results of this study caused a sensation, and natural food stores put up advertisements for "** cat's claw" to attract customers.

Reproduction, the death of an individual does not affect the reproduction of this species, unless a large number of deaths.

The Red Book of China's Endangered Animals was compiled by the International Union for Conservation of Nature (IUCN), and the endangerment classification of species is divided into: extinct wild, extinct, endangered, endangered, critical, rare, vulnerable, etc. It plays an important role in determining the degree of threat to endangered species in China.

The Red Book of Endangered Animals of China is divided into four volumes: birds, fish, amphibians, reptiles and mammals. This paper discusses in detail and comprehensively the endangered status, risk factors, and protection measures of endangered animals in China, aiming to make the first department, the scientific community and the public have a clearer understanding of the current status of animal species in China, improve the awareness of the protection of endangered species in China, and formulate and implement corresponding protection measures according to the current situation, so as to provide a scientific basis for the protection and sustainable use of species in China.

In addition, the Red Book of Endangered Animals database of China collects detailed descriptions of 592 endangered animal species in China, including endangered fishes, amphibians, reptiles, birds, and mammals.

This paragraph] about the bird volume.

Bird volume of the Red Book of Endangered Animals of China. This paper discusses the taxonomic status, endangerment level, population status, risk factors, existing protection measures, and breeding status of bird species in China. This book can be used as a reference for scientific researchers engaged in the study of endangered species, staff of agriculture, forestry, environmental protection and nature reserves, and teachers and students of relevant majors in colleges and universities.

Preface to the book: Editor's remarks: A description of the classification of endangered birds in China.

This paragraph] is about fish rolls.

These endangered species include: 52 species of carps, 11 species of catfish, 5 species of sturgeon, 6 species of salmon trout, and 18 species of the rest (eels, etc.).

There are 4 levels of endangerment: extinct (4 species), rare (23 species), endangered (28 species), and endangered (37 species).

While there are many causes of biological endangerment, the obvious causes are the loss of habitat and changes in the environment. For fish, the main causes of danger are environmental changes caused by hydropower projects, land reclamation, overexploitation of fishery resources, pollution of water bodies, blind introduction of fish and ineffective enforcement of fishery laws.

There are 2 rare species of mammals, including 2 species of water musk glider and Gansu mole, 3 endangered species of clouded leopard, golden leopard and forest musk deer, and 13 species of vulnerable species, including macaque, short-tailed monkey, compound toothed flying squirrel, wolf, black bear, black-throated marten, water cunning otter, great civet, leopard cat, golden cat, roe deer, impala and serow.

Endangered species include clouded leopards.

Biodiversity on Earth is declining at a high rate, and many species are threatened with extinction. The main threats to wildlife survival are habitat loss, commercial exploitation, and internationalization of wildlife and its products. At present, our resources are very limited, and we must be targeted and propose specific protection measures for the endangerment level of the species.

The Red Book of Chinese Plants is formulated with reference to the IUCN Red Book grades, and adopts three grades: "endangered", "rare" and "gradually endangered". 1) Endangered: A species is in danger of extinction at any time within all or significant ranges of its distribution.

These plants are usually sparsely grown, have low individual and population numbers, and are highly narrowly distributed. It is endangered due to habitat loss or destruction, or overexploitation. 2) Rare:

Although there is no immediate risk of extinction, species have very narrow or scattered ranges or are uncommon monospecific or oligogeneous. 3) Critical: The survival of species is threatened by human activities and natural causes, and these species may be classified as "endangered" in the near future due to dry deforestation, habitat degradation and overexploitation.

ICUN (International Union for the Conservation of Nature and Natural Resources), established in October 1948, is currently the largest nature conservation organization in the world. By the end of 1994, 100** and 550 non** groups in 126 countries had signed the IUCN Charter. IUCN has published the Red Data Book of Endangered Species since the 60s.

Species are classified as endangered according to their degree of threat and estimated extinction risk. Based on the information collected and available, and based on the report of the IUCN Species Survival Commission, the IUCN develops a global Red Book.

On June 19, the 2012 IUCN Red List of Threatened Species was unveiled at the United Nations Rio 20 Earth Summit. Of the 63,837 species assessed, 801 are extinct, 63 are extinct in the wild, 3,947 are critically endangered, 5,766 are endangered, and 10,104 are vulnerable (vulnerable). Of the 19,817 threatened species, 41% are amphibians, 33% are corals, 25% are mammals, 13% are birds, and 30% are pines and cypresses.

I haven't seen it in China this year.

It's just that some animals are extinct, not all! Otherwise, there wouldn't be us. There are many reasons for the extinction of animals, the most important reason should be the selection of the natural environment, and those who do not adapt to the environment will be extinct. Of course, there are many other factors, such as human factors.
