Global Warming 原因 中英對(duì)照.doc

原因分析人為因素1.人口劇增因素Dramatic increase in the population人口的劇增是導(dǎo)致全球變暖的主要因素之一。同時(shí)，這也嚴(yán)重地威脅著自然生態(tài)環(huán)境間的平衡。這樣多的人口，每年僅自身排放的二氧化碳量就將是一驚人的數(shù)字，其結(jié)果就將直接導(dǎo)致大氣中二氧化碳的含量不斷地增加。The population factor is one of the main reasons in global warming. At the same time, this is a serious danger to the balance between natural environment. So large the population is, each year only the amounts of their own carbon dioxide emissions would be a staggering figure. And this result will lead directly to the increase of carbon dioxide in the atmosphere. 2.大氣環(huán)境污染因素Environmental factors環(huán)境污染的日趨嚴(yán)重已構(gòu)成一全球性重大問(wèn)題，同時(shí)也是導(dǎo)致全球變暖的主要因素之一。21世紀(jì)，關(guān)于全球氣候變化的研究已經(jīng)明確指出了自上個(gè)世紀(jì)末起地球表面的溫度就已經(jīng)開始上升。Nowadays environmental pollution has turned major global problem, also lead to global warming. Now, global climate change research has clearly pointed out that since the end of last century , the Earths surface temperature has begun to increase .3.海洋生態(tài)環(huán)境惡化因素Deterioration of the marine environment factors海平面的變化是呈不斷地上升趨勢(shì)，根據(jù)有關(guān)專家的預(yù)測(cè)到下個(gè)世紀(jì)中葉，海平面可能升高50cm。如不采取及對(duì)措施，將直接導(dǎo)致淡水資源的破壞和污染等不良后果。At present, the sea-level was constantly on the rise, according to the experts forecast ,at the middle of the next century, sea levels could rise by 50cm. And if we do not take measures, that will lead to the damage and pollution of fresh water resources . 4.土地遭破壞因素The land damage factors眾所周知良好的植被能保持水土流失。但人類活動(dòng)由于為獲取木材而過(guò)度砍伐森林、開墾土地用于農(nóng)業(yè)生產(chǎn)以及過(guò)度放牧等原因，仍在對(duì)植被進(jìn)行著嚴(yán)重的破壞,可能造成大范圍洪澇災(zāi)害和沙塵暴，給社會(huì)造成重大經(jīng)濟(jì)損失，并惡化生態(tài)環(huán)境。As is known to all, a good vegetation can prevent the soil and water loss. But due to human activities to get wood and cut down forest, cultivate land for agricultural production, there is still much serious damage to vegetation. And it can cause floods and dust storms, cause great economic loss to the society and worsen natural environment.5.森林資源銳減因素the sharp drop in forest resources factor在世界范圍內(nèi)，由于受自然或人為的因素而造成森林面積正在大幅度地銳減。Due to natural or man-made factors, forest resources around the world is significantly reduced.6.酸雨危害因素Acid rain酸雨給生態(tài)環(huán)境所帶來(lái)的影響已越來(lái)越受到全世界的關(guān)注。酸雨能毀壞森林，酸化湖泊，危及生物等。世界上酸雨多集中在歐洲和北美洲，多數(shù)酸雨發(fā)生在發(fā)達(dá)國(guó)家，一些發(fā)展中國(guó)家，酸雨也在迅速發(fā)生、發(fā)展。Acid rains impact on the environment has drawn more and more attention around the world. Acid rain can do damage to forests, lakes and threaten the biological. At present, acid rain occurred in most developed countries, but in some developing countries, acid rain also happened rapidly.7.物種加速滅絕因素Speed up the extinction of species on Earths biological factor地球上的生物是人類的一項(xiàng)寶貴資源，而生物的多樣性是人類賴以生存和發(fā)展的基礎(chǔ)。但是地球上的生物物種正在以前所未有的速度消失。Biological species on Earths is a valuable resources and biological diversity of species is the basis of human existence and development. However, the biological species on earth is disappearing at an unprecedented rate.8.水污染因素Water Pollution factors據(jù)全球環(huán)境監(jiān)測(cè)系統(tǒng)水質(zhì)監(jiān)測(cè)項(xiàng)目表明，全球大約有10%的監(jiān)測(cè)河水受到污染。人類的用水量正在急劇地增加，同時(shí)水污染規(guī)模也正在不斷地?cái)U(kuò)大。由此可見(jiàn)，水污染的處理將是非常地迫切和重要。According to the Global Environment Monitoring System of water, about 10% river water is polluted. Water consumption is in a sharp increase , water pollution is becoming more and more serious.This shows that taking measures to protect water will be very important and urgent.9.有毒廢料污染因素 Toxic waste factor不斷增長(zhǎng)的有毒化學(xué)品不僅對(duì)人類的生存構(gòu)成嚴(yán)重的威脅，而且對(duì)地球表面的生態(tài)環(huán)境也將帶來(lái)危害。The growing number of toxi
