这个是关于濒危动物大熊猫的,截选其中一段你认为合适的
The Giant Panda is a mammal classified in the bear family (Ursidae), native to central-western and southwestern China.[2] The Giant Panda was previously thought to be a member of the Procyonidae (raccoon) family.[3] It is easily recognized by its large, distinctive black patches around the eyes, over the ears, and across its round body. Though belonging to the order Carnivora, the Giant Panda has a diet which is 99% bamboo. The Giant Panda may eat other foods such as honey, eggs, fish, yams, shrub leaves, oranges, and bananas when available.
The Giant Panda lives in a few mountain ranges in central China, in Sichuan, Shaanxi, and Gansu provinces. It once lived in lowland areas, but farming, forest clearing, and other development now restrict the Giant Panda to the mountains.
The Giant Panda is a conservation reliant endangered species. According to the latest report,[4] China has 239 Giant Pandas in captivity and another 27 living outside the country. It also estimated that around 1,590 pandas are currently living in the wild.[4] However, a 2006 study, via DNA analysis, estimated that there might be as many as 2,000 to 3,000 Giant Pandas in the wild.[5] Though reports show that the numbers of wild pandas are on the rise,[6][7] the International Union for Conservation of Nature believes there is not enough certainty to remove the Giant Panda from the endangered animal list.[8]
While the dragon has historically served as China's national emblem, in recent decades the Giant Panda has also served as an emblem for the country. Its image appears on a large number of modern Chinese commemorative silver, gold, and platinum coins. Though the Giant Panda is often assumed to be docile, it has been known to attack humans, presumably out of irritation rather than predatory behavior.
这是介绍濒危动物的濒危动物 Endangered species An endangered species is a population of an organism (usually a taxonomic species), which because it is either (a) few in number or (b) threatened by changing environmental or predation parameters, is at risk of becoming extinct. Many countries have laws offering special protection to these species or their habitats: for example, forbidding hunting, restricting land development or creating preserves. Only a few of the many endangered species actually make it to the lists and obtain legal protection. Many more species become extinct, or potentially will become extinct, without gaining public notice. The greatest factor of concern is the rate at which species are becoming extinct within the last 150 years. While species have evolved and become extinct on a regular basis for the last several hundred million years, the number of species becoming extinct since the Industrial Revolution has no precedent in biological history. If this rate of extinction continues, or accelerates as now seems to be the case, the number of species becoming extinct in the next decade could number in the millions[1]. While most people readily relate to endangerment of large mammals or birdlife, some of the greatest ecological issues are the threats to stability of whole ecosystems if key species vanish at any level of the food chain. Species extinction is the ultimate concern, but there are four different reasons to have for concern with this outcome: Loss of a species as a biological entity; destabilization of an ecosystem; endangerment of other species; loss of irreplaceable genetic material and associated biochemicals. The loss of a species in and of itself is an important factor, both as diminution of the enjoyment of nature and as a moral issue for those who be
