Giant pandas have lived on Earth for at least 8 million years and are known as "living fossils". According to the third national giant panda population survey, there are less than 1,600 wild giant pandas in the world, which are China's national first-class protected animals. The lifespan of giant pandas in the wild is 18-20 years, and in captivity they can exceed 30 years.
The giant panda is endemic to China, and its main habitat is in the mountainous areas of Sichuan, Shaanxi and Gansu in China. The giant panda's feeding habits are one of its most peculiar and interesting habits, as it lives almost entirely on bamboo, which accounts for 99% of the year's annual diet of more than 50 species of plants that feed naturally in the wild.

The first point is what causes the animal to be endangered, is it a living environment, or is it a food for him, or a biosphere for his biological chain? Reached a devastation, and one of his is how to protect these endangered animals.
-
How should we protect endangered animals, whether to release them into nature, or to establish protection bases, and most importantly, whether to prohibit hunting and killing.
-
How did these animals become extinct? We should protect them, not hurt them.
-
There are many endangered animals in China that need to be protected, such as the Tibetan antelope, the giant panda in Sichuan, the Siberian tiger, the snow leopard in Taiwan, the golden snub-nosed monkey, the Yangtze white-sided dolphin, etc.
-
China's endangered animals include giant pandas, white-sided dolphins, and golden snub-nosed monkeys. Their number is decreasing. Coupled with man-made hunting and environmental changes, it is our responsibility to protect them.
-
As for endangered animals, we should take them seriously. Don't hurt them. and neither can they be killed.
-
When it comes to endangered animals, we should take them seriously. Don't hurt them.
-
The question about endangered animals is how did these animals become extinct?
-
We want to protect the animals and not harm them.
-
I have a lot of questions, I don't understand, and I want you to explain them to me.

Giant panda. Zhu. Alligator.

Why do some animals become extinct?
-
1. White-sided dolphins.
Since 1996, the white-sided dolphin has not been found in the wild, and several white-sided dolphins have died in captivity, and many domestic and foreign experts believe that the white-sided dolphin may be extinct.
2. South China Tiger.
The South China tiger is a subspecies of tiger endemic to China, which is only found within the territory of China. The South China tiger population has plummeted, and the endangered threat is due to a combination of habitat destruction, increased human activity, commercial or retaliatory hunting, and highly inbreeding of captive South China tigers. So far, there are about 110 South China tigers in captivity around the world.
3. Crested ibis. The current condition of the crested ibis is slightly better than that of the South China tiger, and although there are not many wild numbers, captive breeding has achieved good results. The crested ibis was called the crested ibis and the red crested ibis in ancient times, and the crested ibis is endemic to East Asia.

How can we protect the environment so that they have a place to live?

1. The direct destruction of natural disasters causes a large number of individuals in certain small animal populations to die. Severe food shortages caused by natural disasters have led to mass starvation and death of an animal population. For example, in 1983, the giant panda population died due to the large-scale flowering and death of the staple bamboo, which seriously threatened the survival of the giant panda population.
2. Due to the direct or indirect influence of human activities, animal populations form geographically isolated small populations, and such small populations are most likely to become special and difficult to adapt to drastic changes in habitats, and they are generally the first to become extinct;
3. Some large animals at the top of the food chain, such as South China tigers and Siberian tigers, are easily endangered once they encounter food and habitat damage and rapid changes due to their small populations.
4. Wild animals with high economic and commercial value, such as snow leopards and sika deer, are hunted in large quantities by humans and become endangered;
5. Population reproduction is impaired due to reduced gene exchange opportunities and inbreeding due to the reduction of gene exchange opportunities in animal residue populations;
6. Human economic activities and modern production have caused serious damage and pollution to the natural environment, resulting in the damage and death of individual animals, such as white-sided dolphins and red-necked cranes.
-
The key reason for this problem must be that there is no living space for animals, or that there are relatively few survivors due to diseases.
The former cause is more likely.

1. Giant pandas.
1. It is only distributed in the bamboo forests of the mountains and green mountains in about 40 counties of Sichuan, Shaanxi and Gansu in China, and lives a secluded life without contention. The giant panda, commonly known as the "panda", is one of the most precious animals in the world, the number is very rare, it belongs to the national first-class protected animals, the body color is black and white, and it is known as "China's national treasure".
2. As of 2014, the wild population of giant pandas in China has reached more than 1,800, and the threat level may be downgraded from endangered to vulnerable.
On September 4, the International Union for Conservation of Nature (IUCN) announced in Hawaii that the threat level of the giant panda would be changed from endangered to vulnerable.
2. White-sided dolphins.
1. The white-sided dolphin is an endemic water beast in the middle and lower reaches of the Yangtze River in China, there are more than 70 species of dolphins in the world, only 5 species in freshwater, and the only freshwater whale in China, which is narrowly distributed and older and rarer than the giant panda.
On August 8, the species was officially declared extinct.
3. South China Tiger.
1. The South China tiger is an endemic subspecies in China, which was originally the most widely distributed, the most numerous, and the smallest in size, but the oldest tiger species in China. There is only one species of tiger in the world, and both of them are found in Asia.
2. In the last century, there were still 8 subspecies: Bengal tiger, Siberian tiger, Javan tiger, South China tiger, Caspian tiger, Bali tiger, Sumatra tiger, but the latter three subspecies became extinct one after another, and China's Xinjiang tiger became extinct in the early 20th century.
Fourth, the Chinese alligator.
1. The Chinese alligator is the only crocodile species in China. There are 25 species of crocodiles in the world, and only the bay crocodile and the Chinese alligator are Chinese.
2. The bay crocodile is the largest reptile in the world, and the Chinese crocodile is now endemic to China and the only relict species from the ancient north that is distributed in the temperate zone.
5. Elk. 1. "Four Differences" is the common name of the elk, which is a wetland deer unique to China, which was extinct in China in 1900, but fortunately a small number survived in Europe, and the population was restored after a century of conservation.
2. Elk is a wetland animal, due to the adaptation to the wetland habitat, and the formation of a special form, that is, the so-called "four unlike", the horns like a deer not a deer, the face like a horse not a horse, the hooves like a cow not a cow, the tail like a donkey not a donkey.

China is a large country in the distribution of endangered animals. According to incomplete statistics, there are more than 120 species of endangered animals native to China (referring to species originating in China) that are listed in the appendix of the International Convention on Endangered Species of Wild Fauna and Flora, 257 species are included in the List of Wild Animals under National Key Protection, 400 species of birds, amphibians and reptiles and fish are listed in the Red Book of Endangered Animals of China, and hundreds of species are listed in the list of wild animals under key protection in various provinces, autonomous regions and municipalities directly under the Central Government. With the sustained and rapid development of the economy and the deterioration of the ecological environment, the number of endangered animal species in China will increase.
-
Now there are a lot of endangered animal species, I hope not to ask so general, some endangered animals have been effectively protected, the number is increasing year by year, some endangered animals are going extinct, because there is no time to protect, anyway, it is inseparable from human activities, so we must protect the environment.

1.Change and destruction of the living environment. Due to population growth and economic development, the demand for natural resources is increasing, and the over-cutting of forests, grassland reclamation, overgrazing of grasslands, and the reclamation of lakes and fields have all led to the destruction of the living environment of wild life, so that the life is on the verge of extinction.
2.Predatory exploitation and exploitation. Indiscriminate hunting and deforestation pose a clear threat to the survival of organisms3Environmental pollution. Such as industrial waste and domestic sewage.
4.Invasion or introduction of alien species into areas where natural predators are lacking.
