Animals Need Protecting
Everyone knows animals are our friends. So we should be friendly to them. But some people kill the rare animals, such as pandas, golden monkeys and so on in order to get money. It will cause these animals to disappear soon. I think our government should punish those people severely who kill the rare animals. It is our duty to protect the endangered animals.

Animals Need Protecting
Animals are natural resources that people have wasted all through our history. Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today. About 170 kinds in the United States aloneare considered in danger.
Why should people care? Because we need animals, and because once they are gone, there will never be any more.Animals are more than just beautiful or interesting. They are more than just a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems. For example, when farmers killed large numbers of hawks, the farmers' stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice, with no hawks to keep down their numbers, the rats and mice multiplied quickly.

Animals Need Protecting
Earth's biological diversity is being fast decline of many species facing extinction. Threat to the survival of wild animals and plants is a major factor in habitat loss, business development, and wild animals and plants and their products in international trade. Resources are limited, it is necessary for the endangered species, to propose specific measures of protection level. We can formulate the corresponding endangered species laws, application to establish nature reserves, endangered species breeding centers, means of conservation biology, endangered species, the implementation of in situ conservation and ex situ conservation. At the same time, we must restrict international trade in Endangered Species of Wild Fauna and Flora, to make laws to protect endangered species.

Many wild animals are facing the danger of extinction, because the environment that they are living in has changed greatly. For example, with the developmet of cities, the using of insecticide and serious pollution, their living areas have become narrowcr and narrower. Many of the wild animals, now are confronted with food crisis. At the same time, man is killing off species just for getting their fur, skin, horns, teeth and meat.
In order to protect our resources of ecology, people should realize that the loss of any species is at least the loss of source of knowledge and a source of natural beauty. There fore, measures of the following should be taken: pollution standards are made to keepdown poisons; killing off certain rare species is prohibited; national parks should be set up as wild life, reserves.
Only if we human beings take some drastic measures can wild animals be preserved.
許多野生動物正面臨絕種的危險，因?yàn)樗鼈兩畹沫h(huán)境發(fā)生了極大的變化。譬 如，隨著城市的發(fā)展，殺蟲劑的使用和嚴(yán)重的污染，野生動物的生活區(qū)域變得越來越狹小。許多野生動物目前正面臨著食物方面的危機(jī)。同時，為了獲取野生動物的毛、皮、角、牙齒和肉，人類正在屠殺野生動物。
為了保護(hù)生態(tài)資源，人們應(yīng)當(dāng)意識到任何物種的缺失，至少意味著知識資源和自然美的缺失。因此，應(yīng)采取以下措施：制訂污染標(biāo)準(zhǔn)以降低有毒物質(zhì);嚴(yán)禁殺害某些稀有物種;應(yīng)建立國家公園作為野生動植物保護(hù)區(qū)。
我們只有采取一些有力措施，才能保護(hù)野生動物。

Many animal populations facing threats
A worldwide study has found that almost twenty-five percent of wild mammals are in danger of permanently disappearing. Scientific researchers considered all known mammal populations. The researchers say permanent disappearance threatens at least one thousand one hundred forty-one species or groups of animals. Mammals are the closest relatives to human beings.
The researchers are blaming loss of habitat, or living space, and hunting for threatened land mammals. They say water mammals suffer more from pollution, being hit by ships and caught in fishing nets.
One thousand seven hundred experts worked on the study. They are from one hundred thirty countries. Their findings were reported at the World Conservation Conference of the International Union for Conservation of Nature in Barcelona, Spain.
The report was presented in connection with the Red List of Threatened Species. The World Conservation Conference announces the Red List each year. The list contains almost forty five thousand animals and plants. Of those, almost seventeen thousand, or about thirty eight percent, are threatened with extinction.
Some scientists say the report provides evidence that Earth's wildlife is going through widespread extinction. The last such period may have taken place millions of years ago, when dinosaurs became extinct.
Jan Schipper led the writing of the report. He directs the I.U.C.N.'s program that observes animal populations worldwide.
Mister Schipper says up to thirty six percent of mammals could be facing extinction. He says this is true because not much information exists about some species. At least seventy-six mammals have permanently disappeared since fifteen hundred.
The director general of the I.U.C.N., Julia Marton-Lefevre, says human activity could cause loss of hundreds of species. She says that is a frightening sign of what is happening to habitats. Still, the report said human efforts also could help save some species. Miz Marton-Lefevre is calling for action to make that happen.
For study purposes, the I.U.C.N. divides animals into groups. The scientists call animals that have disappeared, or almost disappeared, extinct or nearly extinct. A frog-like creature called Holdridge's toad was declared extinct. It lived only in Costa Rica.
Other divisions depend on the amount of threat the animals face. The animals in most danger are considered critically endangered.
For example, the Iberian lynx is called critically endangered. As few as eighty-four adult members of the large, cat-like animals remain alive.
The Red List identifies the second most threatened animals as endangered. The scientists named a Southeast Asian animal, the fishing cat, as among the endangered. Part of the fishing cat's wetland habitat no longer exists.
A new study suggests the last woolly mammoths in Siberia were native to North America. Scientists had believed these mammoths came from Europe or Asia.
The study involved genetic evidence from the remains of the ancient animal. Woolly Mammoths share an ancestor with modern-day elephants. The mammoth is recognizable for its long hair and large tusks.
Woolly mammoths disappeared thousands of years ago, after Earth's most recent ice age. But mammoths were able to survive for thousands of years. During this period, they slowly changed to live in extremely cold climates.
Scientists believe the ancestors of woolly mammoths came from Africa. As the African mammoths moved north to Eurasia, scientists believe, they grew long hair to protect them from the extreme cold of Siberia.
To better understand these animals, an international research team examined genetic material from more than one hundred woolly mammoth remains. The remains were found in North America, Europe and Asia. These fossils came from woolly mammoths that lived between forty-four thousand and eleven thousand years ago.
Hendrik Poinar is a molecular evolutionary geneticist at McMaster University in Ontario, Canada. He and his team examined genetic material from fossilized teeth and pieces of bones from woolly mammoths. They also examined results of earlier woolly mammoth studies.
Until recently, many scientists believed that mammoths came from Europe and Asia because that is where the oldest fossils were found. Earlier studies of the mammoths involved only one continent at a time. The researchers discovered that mammals traveled back and forth several times between Eurasia and Alaska over thousands of years. The animals were able to travel on a land bridge that connected Siberia and Alaska during low sea levels.
The researchers discovered that the mammoths were divided in three major groups. One group lived mainly in Asia. Another group lived mainly in the Americas. And, a third group lived in both places. They believe the American mammoths traveled back across the Bering Strait and in time replaced the other populations of mammoths.
The researchers believe the animals moved the great distances in search of food. A report with their findings was published in Current Biology. Other researchers disputed the findings. They say the study is based on only limited information.
