1)、物种自身的原因
物种特化和遗传衰竭,往往是导致物种濒危甚至灭绝的内在原因。某些种类的野生动物在长期的进化过程中,适应了某种特定的栖息环境而产生了特别的习性(包括食性),使其难以适应变化了的环境或其他环境,最终落得“不适者被淘汰”的结局。如大熊猫特化为主要以竹为食,一旦失去其现有栖息地或竹子大面积开花枯死,大熊猫无竹可食,必然大批死亡,出现生存危机。 一些野生动物在长期的演化过程中,由于种种原因而受到生活力减退和遗传力衰退的威胁,导致其种群数量难以恢复而趋于濒危
2)、栖息地破坏与丧失
人类为发展经济砍伐森林、围湖围海造田、过度放牧等,直接造成了野生动物栖息地丧失,间接导致了野生动物的濒危。森林和草原是野生动物,特别是兽类、鸟类、爬行类以及昆虫最主要的栖息地之一。森林的砍伐和紧随其后的开荒种地以及草原过度放牧,既占据了野生动物固有的家园,又将野生动物人为地分割成许多孤岛状的小种群,使得它们的生存繁衍遭到极大的影响。?
4)、环境污染
本世纪以来,由于农药、鼠药、化肥、煤炭、石油的广泛使用,产生了大量工业“三废”和有毒物质,严重污染了大气、土壤和水体,野生动物健康受到损害,繁殖力日渐低下,许多江河湖泊已不再适于水生野生动物的生存繁衍。某些生态位较高的野生动物因为食物链的关系也受到了程度不同的株连。

谢谢各位了!
语法要正确!太感谢了

The reasons for their species

Special species and genetic failure, often leading to endangered species and even the underlying causes of extinction. Certain types of wild animals in the long-term evolution, adapted to a particular habitat and have had a special habits (including diet) to make it difficult to adapt to changes in the environment or other environmental and eventually end up "does not have been Out of "ending. Such as the giant panda into a special bamboo mainly for food, lose their existing habitat or a large area of bamboo flowering dead, no giant edible bamboo, a large number of inevitable death, appeared to survive the crisis. Some of the wildlife in the long-term evolution, for various reasons have been viability receded and the heritability of the threat of a recession, leading to its population and tend to be difficult to restore endangered
