1. 防止海洋污染的英语作文

Pollution

Sea pollution is becoming an increasing problem for our planet and we have a responsibility to reduce sea pollution.

I need to describe the problem. Our ship currently dumps all its rubbish into the sea.It's easy to result in huge endanger. First of all, Non-organic substances such as plastic bags kill fish and whales. Because fish get trapped and whales cannot digest them. Secondly some rubbish is inherently toxic.

I can suggest some solutions. First and foremost we can create a better system of disposing of rubbish for instance. We ought to store rubbish. Next, we are supposed to make ships environmentally and friendly. A case in point is that we should stop providing plastic bags.

We must act now before it is too late!

海洋污染英语作文二:Reduce Sea Pollution

Several problems are caused by the non-organic substance. We ought not to pour wastes into the ocean, because it not only pollutes the ocean, but also lead to a series of harmful consequence. First and foremost, the non-organnic things, for instance, plastic bags, may kill fish and whales. Second, fishes can't digest them. Finally, some of the rubbish is inherently toxic, they will posion marine life.

We must take actions to protect our whale from dying. One thing we should do is creating a better system of disposing of rubbish. Another effective solution is making ships environmentally friendly. Sypermarkets shall stop the giving of plastic bags.

As a captain of the ship, you should spare no efforts to think more helpful ideas and stop dumping rubbish from now on. We all need to raise awareness of these problems. It now becomes necessary that we must act now, before it is too late!

海洋污染英语作文三:Sea pollution

Between 75 and 80% of marine pollution is caused by land, particularly agriculture. 30% of this is from the atmosphere. Around 12% of the pollution is caused by maritime transport.

In South America, 98% of domestic wastewater ends up, untreated, in the sea. The countries along the Mediterranean Sea throw 50 million tons of waste into it every year and the Chinese throw 60 million tons of waste into the Yellow sea daily. Over half of the hydrocarbon discharge comes from continents, 5% comes from oil tanker accidents, 20% comes from waste and other ship-related accidents, 4% from sea exploitation and 11 to 15% is due to natural causes. Accidental pollution through hydrocarbon is significantly decreasing and only represents a small percentage of waste through degassing estimated at between 1.5 and 3 million tons of oil a year. In 2003, according to the WWF, between 0.7 and 1.3 million tons of oil were spread by degassing in the Mediterranean. According to the Ifremer (the French Institute for Exploitation of the Sea), coastal water pollution cost the world economy almost 12.8 billion dollars in 2006.

Marine pollution is the result of products being thrown into seas and oceans, mostly by mnkind: domestic waste (sewage and rubbish, pollutants in runoff water...), industrial waste (hydrocarbons, metals, synthetic chemical and organic substances, radionuclides...) and agricultural waste (fertilisers, pesticides...).

This includes water pollution and marine sediments, and more generally all damage to marine ecosystems caused by harmful substances being discharged into the sea, either by their nature or their quantity.

海洋污染英语作文四:Sea Pollution

Marine environment is one in water, seawater tolerance hydrolyzate and suspended solids, seabed sediment and marine organisms, including complex systems. Ocean rich biological resources, mineral resources, chemical resources and power resources is an indispensable resource treasure house of human beings, with human survival and development of the relationship very close.

The main objective of the current marine conservation is to protect the living marine resources, so as not to failure, in order for human sustainable use. In particular, give priority to protect those valuable and critically endangered marine life. According to the UN for investigation, due to overfishing, accidental capture and killing of non-target to allow hunting of marine, coastal shoreline construction, mangrove deforestation, widespread marine pollution, at least the world's 25 most valuable fishery resources depleted, whales, sea turtles, manatees and many other marine animals face extinction risk. Is expected that with the expansion of the scale of ocean development,Marine living resources are likely to cause more damage.

The task of the first marine protected right to stop over-exploitation of living marine resources and secondly to protect the habitat of marine life or habitat, in particular, their migration, spawning, foraging, avoiding predators coast, tidal flats, estuaries, coral reefs, it is necessary to prevent the heavy metals, pesticides, oil, organic and easy to produce nutrients such as eutrophication of marine pollution. Preservation of the marine living resources of the natural regeneration capacity and water purification capacity, preservation of the marine ecological balance, to ensure sustainable human development and utilization of the oceans.

海洋污染英语作文五:Polluting the seas

The seas and oceans receive the brunt of human waste, whether it is by deliberate dumping or by natural run-off from the land.

In fact over 80% of all marine pollution comes from land-based activities and many pollutants are deposited in estuaries and coastal waters. Here the pollutants enter marine food chains, building up their concentrations until they reach toxic levels. It often takes human casualties to alert us to pollution and such was the case in Minimata Bay in Japan when many people died as a result of a pollutant building up in food chains. A factory was discharging waste containing methyl mercury in low concentrations into the sea and as this pollutant passed through food chains it became more concentrated in the tissues of marine organisms until it reached toxic levels.

As a consequence 649 people died from eating fish and shellfish contaminated with mercury and 3500 people suffered from mercury poisoning.

From the overall situation, wastewater emissions growth speed. Is expected in 2000 will reach 666 tons. City life sewage volume will continue to increase, in 2000 reached about 783 tons. The wastewater of low (estimated at 20% ~ 30%),most of untreated wastewater directly or indirectly discharged into the water body, the serious pollution of water resources. China's seven major river systems in nearly half of serious pollution, city section of river water qualitygenerally exceed the standard 86%. The polluted water, more serious is the Huaihe, Haihe, Liaohe, Songhua River, the downstream Yangtze River and the Pearl River Delta industries in developed region.

River city section of riverpollution, heavy on the river, north to south. In 1990, 94 river city section of evaluation, 65 are subject to different degrees of pollution, accounting for 69.1%, the main pollutants ammonia nitrogen, volatile phenol and oxygen consumption of organic matter. According to the survey, 700000000 peopledrinking water the Escherichi a coli exceed the standard, 164000000 people drink organic pollution of water, 35000000 people nitrate drinking water exceed the standard.

Huaihe is one of the most polluted rivers. Huaihe in the evaluation of the 2000kilometers of the river, 78.7% river does not meet the drinking water standard,the 79.7% section does not meet the standard of fishery water, 32% do not meet the standard of irrigation water. According to statistics, the national 3000 heavily polluting enterprises, enterprises of wastewater discharge of industrial pollution,Huaihe River Basin accounts for 160. A sewage units 1.55 182 towns within the basin, industrial wastewater emissions of 1610000000 cubic meters, 700000000 cubic meters of urban living water emissions. Huaihe sewage irrigation farmland,causing serious crop production; in 1989 the occasion of the Spring Festival, the sewage discharge upstream gate opening, the tap water in Huainan, Bengbu twocity is seriously polluted and not drinking, Huaihe basin, the public drinking watercrisis, people Voices of discontent.

4. 关于海洋污染的英语作文带翻译

就目前的开采技术而言,基本上无论是哪种方法,都是促使可燃冰中天然气与水的分离,要促使其分离,必然要改变其温度及压力环境,这样就可能会产生一系列不可预知的环境问题,如温室效应的加剧、海洋生态的变化及引起地质灾害的可能。

可燃冰的成分主要是甲烷,甲烷是一种强温室气体,对大气辐射平衡的影响仅次于CO2。

目前探明全球可燃冰储量的甲烷是大气圈中甲烷的5000倍,在开采的过程中,即使如此巨大的甲烷总量哪怕是0.5%进入大气层,对全球变暖的影响也是难以估量的,如果开采中稍有不慎,则必然会加剧温室效应。在海洋中开采可燃冰带来的环境问题更多,一方面甲烷如果直接进入海水中,则会很快发生微生物的氧化反应,从而会改变海水的化学属性,如果大量进入,其氧化过程中会消耗海水中大量的氧气,使得海洋缺氧,这样势必会加速海洋生物的死亡;

另一方面大量直接进入海洋的甲烷还可能会加速海洋气化及海啸,导致海水加速流动及气压卷吸,会严重危害海面船只及作业平台的安全,甚至强对流的海水会直入空中,影响航空及陆地建筑的安全。

在开采可燃冰的过程中,会分解大量的水,这些水会稀释岩层空间,使得地层结构稳定性变差,容易引发地质灾害。

在海洋环境中,无论是减压分解还是激热分解,都会导致海底陆坡区的稳定性下降,严重则会发生海底坍塌,如毁坏海底输电或通信电缆和海洋石油钻井平台等设施。

就目前的开采方法来看,无论是哪种方法都不能单独实施,必须是几种方法的结合,如果使用二氧化碳置换法、化学试剂减压法与其他方法的结合实施,则势必会产生新的问题,这些化学试剂及二氧化碳注入到地下后,会严重污染地下水源。

6. 海洋污染的英语演讲稿

海洋是生命的摇蓝。从第一个有生命力细胞诞生至今,仍有20多万种生物生活在海洋中,其中海洋植物约10万种,海洋动物约16万种。从低等植物到高等植物,植食动物到肉食动物,加上海洋微生物,构成了一个特殊的海洋生态系统,蕴藏着巨大的生物资源。据估计,全球海洋浮游生物的年生产量(鲜重)为5000亿吨,在不破坏生态平衡的情况下,每年可向人类提供300亿人食用的水产品,这是一座极其诱人的人类未来食品库!   海洋生物资源有其自身的特点:它是有生命的,能自行增殖,并不断更新的资源,但从另一方面说,它因为是通过活的动植物体来繁殖发育,使资源以更新和补充,具有一定的自发调节能力,是一个动态的平衡过程。但是一旦其生态系统平衡遭到破坏,就意味着海洋生物资源的破坏。   藻类在海洋生物资源中占有特殊的重要地位。它能够自力更生的进行光合作用,产生大量的有机物质,为海洋动物提供充足的食物。同时,它在光合作用中还释放大量的氧气,总产量可达360亿吨(占地球大气含氧量的70%),为海洋动物甚至陆上生物提供必不可少的氧气。   到这里,还不能不提到一点的是,它是在最初地球大气转变为现代大气中的“功臣”,有了它们,才有了现代生机勃勃的生物界。所以,海洋植物是维持整个海洋生命的基础,是坚固的“金字塔基”。它们主要包括在水中随波逐流的浮游藻类和海底生长的大型藻类。前者如硅藻、绿藻等,它们个体微小,而形状各异,如圆形、方形、三角形、针形等。若仅从外表看上去,你绝想不到它们竟然是活生生的植物。   大型藻类有人们熟悉的紫菜、海带等。它们在海底构成“海底农场”,有森林,又有草原。有一种巨藻,堪称世界植物之最,从几十米,至上百米,最高可达500米高,重达180多公斤,生长速度之快,一年可长50余米,而且它的年龄可长达12年之久。海藻在工业、农业、食品及药用方面有很重要的价值,除食用外,可从中提取褐藻胶、琼脂、甘露醇、碘等,可作为一种新的生物能源。   海洋生物中最重要、最活泼的当属动物资源,其中有1.5-4万种鱼类,对虾等壳类2万多种,贝壳等软体动物8万多种,还有鲸、海参、海豹、海象、海鸟等,构成了生机盎然的海洋世界,也构成了经济效益很好的海洋水产业,其中鱼类是水产品的主体,也最重要。   目前,全世界从海洋中捕捞的6000万吨水产品中,90%是鱼类,其余为鲸类、甲壳类和软体动物等。鱼类种类较多,可供食用的就有1500多种。鱼类可谓全身是宝,营养经济价值很高,含有大量的蛋白质,味道鲜美。据说,吃鱼可使人大脑聪明,还有的具有医疗价值和作为精细化工业的贵重原料。   在水产上,鱼、虾、蟹总是相提并论的,它们不仅是席上珍馐,而且可从它们的甲壳中提取许多有用的东西——甲壳质,在工业上用途很广。其中生长在南极的一种磷虾被誉为“21世纪的流行食品”因为它有着极为惊人的资源量和很高的营养价值,在南极是鲸类吞食的对象,小小磷虾喂巨鲸,这也是一种奇闻吧。   在海洋中,有一个不可忽视的部分就是海洋微生物,主要是细菌、放线菌、雪菌、酵母菌、病毒等,它们数量极大,分布不均。假设海洋中没有微生物存在,那么海洋中一切物质就不能循环,但它们的活动,也使渔业生产受到一定的损失。近年来,研究表明,在海洋微生物中可以提取一些特殊的生物活性物质,对治疗疾病有奇效。   有一位美国作者提出:“下个世纪,谁来养活中国人”的问题:世界上没有哪个国家有这样的能力,而海洋产业可以将这一任务分担起来,而传统的渔业已达到或超过它的再生能力,所以人们只有转向于研究海洋生物资源开发技术上来,巨大的海洋生物资源,等着开发时代的到来。

鲸落(Whale Fall),指鲸死去后沉入海底的现象。当鲸在海洋中死去,它的尸体最终会沉入海底,生物学家赋予这个过程以鲸落的名字。一座鲸的尸体可以供养一套以分解者为主的循环系统长达百年。鲸落是指鲸鱼死亡后落入深海形成的生态系统,与热液、冷泉一同被称为是深海生命的“绿洲”。在北太平洋深海中,鲸落维持了至少有43个种类12490个生物体的生存,促进了深海生命的繁荣。
