文檔簡介
1、1.海洋作為我們這個世界必不可少的部分,緩解氣候變化帶來的危害,為我們提供視頻和許多現(xiàn)代藥物。但是海洋與人類之間的這種聯(lián)系卻一直沒有引起人們的足夠重視。直到近來,由海洋保護生物學(xué)家Dr.Wallace帶領(lǐng)的團隊,從多學(xué)科角度,探索人類大腦于海洋之間的聯(lián)系,提出一個新的研究方向-神經(jīng)保護。這一研究引起了海洋科學(xué)方面的一場革命。著名海洋學(xué)家Wall Broecker 博士,把深層水流動現(xiàn)象稱為“海洋循環(huán)帶”。這種說法太過簡單的描述了一個復(fù)雜的過程。杜克大學(xué)的Susan Lozier 博士綜合考慮各種證據(jù)后,推翻了我們對于海洋顛覆的觀點。無論這場革命結(jié)果如何,有一點毋庸置疑的,海洋緊密的將地球聯(lián)系在
2、一起。我們呢要摒棄傳統(tǒng)的看法,從一種新的視角來保護海洋。The ocean, as an indispensable part of our world, buffers our weather, and provides us with food and many of modern medicines. However, we just ignored (didnt give enough at tention to the connectivity between the ocean and human sphere. Only until recently, have the team
3、 led by marine conservation biologist Dr. Wallace J. Nichols started to explore the connection between human minds and the ocean from multidisciplinary perspectives. They put forward a new research field neuroconservation, which led to a revolution in marine science.Dr. Wally Broecker, a famous ocea
4、nographer, called the phenomenon of deep water circulation “Ocean Conveyor Belt”. This statement is an oversim plification of a complex process. Dr. Susan Lozier from Duke University overwhelmed the idea about ocean overturning after considering/weighing different pieces of evidence. Whatever the ou
5、tcome would be, there is no doubt that the ocean holds our planet tightly. We have to abandon the old notion and try to protect the ocean from a new perspective.2.海洋是生命的發(fā)源地,因此,對海洋生態(tài)的研究不但有利于保護生物的生存環(huán)境,而且至直接關(guān)系到海洋生物資源的開發(fā)和利用。海洋研究者發(fā)現(xiàn),海洋微生物可以維持地球大氣中氧氣和二氧化碳的平衡,藻類制成的防曬霜可用于皮膚護理行業(yè),鐵施肥自然機制有利于解決海洋鐵缺乏癥,過度捕撈海魚獲取魚油
6、帶來了物種滅絕的風(fēng)險,未經(jīng)處理的廢水或污水流入海水吧人類病原體傳播給了海洋珊瑚,這些都是海洋科學(xué)中一些開拓性研究的發(fā)現(xiàn)。目前,科學(xué)家正在進行一些包括海洋溢油,海洋物種變性,海洋可再生資源的合成等問題的研究。如果將來自實現(xiàn)了在海藻中獲的生物燃料,將對解決人類能源危機等問題有非常重要的作用.The ocean is the cradle of life. Therefore, the study of marine ecology is not only conducive to the survival of the conservation of biological environment,
7、 and is directly related to the development and utilization of marine living resources. Ocean researchers find that marine microbes play an important role in maintaining the oxygen and carbon dioxide balance in the Earth's atmosphere; sunscreens made of algae can be used in skin care industry; a
8、 natural mechanism for iron fertilization is helpful to solve iron deficiency; mass catching of fish for obtaining oil poses risks for extinction of the overfished species; untreated wastewater or sewage which flow into the sea transmits human pathogen to marine corals. These are path-breaking findi
9、ngs in marine science. Researchers are going on various marine biology issues such as oil spills in marine water, ability of some marine species to change their sex and synthesis of renewable energy source. If it is feasible to obtain biofuel from seaweed in the future, it will be a priceless contri
10、bution for solving energy crisis of human beings.3.海洋的狀況堪憂,證據(jù)不勝枚舉。海水變酸,是的許多海洋生物生存困難。某些物種的稀缺會破壞食物鏈,從而導(dǎo)致整個生態(tài)系統(tǒng)的失衡。作為海洋雨林的珊瑚礁,由于受到過度采集,水溫過高,海洋酸化等因素的影響,大部分已受到嚴(yán)重損害。全球變暖使海洋升溫,冰川融化,導(dǎo)致海平面上升,使沿海地區(qū)居民處于危險的境地。人類施加給生態(tài)系統(tǒng)太多壓力,這些壓力可能會永久地改變海洋。對于人類而言。每一種改變都是巨大的災(zāi)難。坐視不管或把這些當(dāng)成小麻煩都不是明智之舉。相反,該是我們采取必要措施扭轉(zhuǎn)這一局面的時候了。在某些情況下,應(yīng)該
11、廢除漁業(yè)補貼,可轉(zhuǎn)讓捕撈配額。在為時已晚之前,我們必須制定出來有效的策略。The sea is suffering. The evidence abounds. It becomes acid, making marine life difficult. The dearth of some species will disrupt the food chain, which will in turn destabilize the entire ecosystem. The coral reefs, as the rainforests of the sea, are affected by
12、 overfishing, overheating, ocean acidification, etc. Most of them are therefore gravely endangered. Global warming causes oceans to warm up and glaciers to melt, which will raise the sea level and endanger the inhabitants of coastal areas. Humans inflict too many stresses on marine ecosystem, which
13、may permanently change the ocean. For humans, each of these changes is a catastrophe. It is not wise for us to sit back or take it for minor distractions. Conversely, it is high time we did something to put matters right. Fishing subsidies should be abolished and fishing quotas be made transferable
14、in some cases. We must develop effective strategies before it may be too late.4.一些科學(xué)家認為有必要采用更為寂靜的方法,即改造地球的方法,來處理氣候問題。這是個有趣的想法。通過對大氣層或海洋驚醒大規(guī)模的改造來改變氣候,這樣的風(fēng)險將會很高,過程也超乎尋常的復(fù)雜。其中有一種方案是增加大氣中的污染物,這一有悖常理的論調(diào)在過去曾被廣泛吹捧,其缺點是它會產(chǎn)生無法預(yù)知的連鎖反應(yīng)。但是另外的一個途徑,即讓全球的人口防竊化石燃料,被證明的極其困難的。即使地球工程的倡導(dǎo)者們,地球工程是不能輕易實施的,但我們也不能完全忽略它的價值。面
15、對全球變暖的威脅,所有的方案都值得探討。地球工程,正如人們所知,可能會為向低碳經(jīng)濟順利過渡贏得一些時間。5.海水中富含微生物。有些產(chǎn)生劇毒,有些通過聚集到一起產(chǎn)生危害。這些對人類造成危害的海藻就叫有害藻類。它步進對人類的健康產(chǎn)生影響(如一些已知,甚至為之的疾病,還對野生動物危害巨大。事實上,50%的海洋動物的非正常死亡和有害藻類有關(guān)。有害藻類對生態(tài)系統(tǒng)的影響是另外一個社會焦點。這種影響有時是自上而下的,比如,對食肉動物和食草動物的影響;有時是自上而下的,比如對浮游生物的影響。盡管人們采取了一些預(yù)防措施,有海藻類對社會經(jīng)濟的影響依然巨大。政府每年花費巨額資金來處理有害藻類所帶來的問題。政府花在公
16、共健康上的錢最多,其次花在了商業(yè)捕魚和旅游業(yè)方面。Marine waters teem with microscopic life. Some of them create potent toxins and some of them do harm by accumulating. The algae causing harm is called Harmful Algal Blooms. It not only has impact on health of human beings (such as some known and even unknown diseases, but on
17、 wild life as well. In fact, more than 50% of the unusual marine mortality events are now associated with HABs. It is another societal concern that HABs have profound influence on ecosystem. Sometimes, the impact works from bottom up (such as affecting predators and grazing, and sometimes from botto
18、m-up (such as affecting plankton. In spite of the precautions, the socioeconomic impact is substantial. Many millions of dollars are spent annually addressing the HAB-related problems. The money on public health accounts for the largest part, followed by commercial fisheries and tourism.6.潮汐能不僅是綠色能源
19、,而且潛力巨大。但英國政府同丹麥和瑞典相比,對它們的利用卻一直不盡如人意。但是事情目前有了轉(zhuǎn)機。英國政府的一項潮汐能利用計劃可能會極大的提高它的利用率。這項計劃將在世界第二大潮差的塞文河上建立三個大壩和兩個潮湖。這項計劃的有時在于潮汐能不同于風(fēng)能,海浪等,他是可預(yù)期的。并且,該項目規(guī)模巨大,可以滿足英國每年5%的發(fā)電量。但是環(huán)保主義者反對,因為大壩將會擾亂塞文河附近的鳥類和魚類的生活。同時也有人認為納稅人將為高昂的建設(shè)成本買單,該項目成本遠高于風(fēng)能項目。該項目到底該何去何從呢?政府考慮到它能創(chuàng)造更多的就業(yè)機會,很可能會通過。到那時將是一個潮汐能利用的里程碑。Tidal power is not
20、 only one of green energy, but also its potential is vast. But compared to Denmark and Sweden, the British governments exploitation is not satisfying. But now things seem to be changing. The project of the British government could provide an enormous boost. It will build three barrages and two tidal lagoons on the river
