破坏大自然的事例?英文双语对照

事例一:森林面积减少

森林被誉为“地球之肺”、“大自然的总调度室”,对环境具有重大的调节功能。因发达国家广泛进口和发展中国家开荒、采伐、放牧,使得森林面积大幅度减少。据绿色和平组织估计,100年来,全世界的原始森林有80%遭到破坏。另据联合国粮农组织最新报告显示,如果用陆地总面积来算,地球的森林覆盖率仅为26.6%。森林减少导致土壤流失、水灾频繁、全球变暖、物种消失等。一味向地球索取的人类,已将生存的地球推到了一个十分危险的境地。

事例二:臭氧层破坏和损耗

自1985年南极上空出现臭氧层空洞以来,地球上空臭氧层被损耗的现象一直有增无减。到1994年,南极上空的臭氧层破坏面积已达2400万平方公里。现在在美国、加拿大、西欧、前苏联、中国、日本等国的上空,臭氧层都开始变薄。在对消耗臭氧层物质(ODS)实行控制之前(1996年以前),全世界向大气排放的ODS已达到了2000万吨。

事例三:罗布泊消失了

塔里木河全长1321公里,是中国第一、世界第二大内陆河。据《西域水道记》记载,20世纪20年代前,塔里木河下游河水丰盈,碧波荡漾,岸边胡杨丛生,林木茁壮。1925年至1927年,国民党政府一声令下,塔里木河改道向北流入孔雀河汇入罗布泊,导致塔里木河下游干旱缺水,3个村庄的310户村民逃离家园,耕地废弃,沙化扩展。解放后的1952年,塔里木河中游因修筑轮台大坝,又将塔里木河河道改了过求。塔里木河下游生态环境得以好转,胡杨枝重吐绿叶,原来废弃的耕地长出了青草,这里变成牧场。

事例四: 水资源枯竭

水是生命的源泉,水,似乎无所不在。然而饮用水短缺却威胁着人类的生存。目前,世界的年耗水量已达7万亿立方米,加之工业废水的排放,化学肥料的滥用,垃圾的任意倾倒,生活污水的剧增,使河流变成阴沟,湖泊变成污水地;滥垦滥伐造成大量水分蒸发和流失,饮用水在急剧减少。水荒,向人类敲响了警钟。据全球环境监测系统水质监测项目表明,全球大约有10%的监测河流受到污染,生化需氧量(BOD)值超过6.5毫克/升,水中氮和磷污染,污染河流含磷量均值为未受污染河流平均值的2.5倍。另据联合国统计,目前全世界已有100多个国家和地区生活用水告急,其中43个国家为严重缺水,危及20亿人口的生存,其主要分布在非洲和中东地区。许多科学家预言:水在21世纪将成为人类最缺乏的资源。正如人们所希望的,不要让人类的眼泪成为地球上最后一滴水。

事例五:海洋资源破坏和污染

据估计,全世界有9.5亿人把鱼作为蛋白质的主要来源。但近几十年来,人类对海洋生物资源的过度利用和对海洋日趋严重的污染,有可能使全球范围内的海洋生产力和海洋环境质量出现明显退化。1993年,在全世界捕捞的1.01亿吨鱼中,有77.7%来自海洋。当年,联合国粮农组织估计,2/3以上的海洋鱼类已被最大限度或过度捕捞,特别是有数据资料的25%的鱼类,由于过度捕捞,已经灭绝或濒临灭绝,另有44%的鱼类的捕捞已达到生物极限。而另一方面,人类活动产生的大部分废物和污染物最终都进入了海洋。全球每年有数十亿吨的淤泥、污水、工业垃圾和化工废物等被直接排入了海洋,河流每年也将近百亿吨0淤泥和废水、废物带入沿海水域,引起沿海生境改变,使动物的栖息和繁殖地遭到破坏。海洋污染的主要来源和比例约是:城市污水和农业径流排放44%,空气污染33%,船舶12%,倾倒垃圾10%,海上油、气生产1%。

The main source of marine pollution and scale are about: Urban foul water and agricultural runoff are discharged 44% , air is polluted 33% , shipping 12% , dump rubbish 10% , production of maritime oil, gas 1% .
