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.

　　保護(hù)野生動物

　　許多野生動物正面臨絕種的危險，因為它們生活的環(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)。
