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.
保护野生动物
许多野生动物正面临绝种的危险,因为它们生活的环境发生了极大的变化。譬 如,随着城市的发展,杀虫剂的使用和严重的污染,野生动物的生活区域变得越来越狭小。许多野生动物目前正面临着食物方面的危机。同时,为了获取野生动物的毛、皮、角、牙齿和肉,人类正在屠杀野生动物。
为了保护生态资源,人们应当意识到任何物种的缺失,至少意味着知识资源和自然美的缺失。因此,应采取以下措施:制订污染标准以降低有毒物质;严禁杀害某些稀有物种;应建立国家公园作为野生动植物保护区。
