1. 海洋污染的危害有哪些英语

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

2. 海洋污染英文小短文

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。

3. 海洋污染用英语怎么说

国际海事组织(英文:International Maritime Organization)是联合国负责海上航行安全和防止船舶造成海洋污染的一个专门机构,总部设在英国伦敦。该组织最早成立于1959年1月6日,原名“政府间海事协商组织”。

1982年5月更名为国际海事组织,截止2012年9月,已有171个正式成员。国际海事组织(简称IMO)的作用是创建一个监管公平和有效的的航运业框架,普遍采用实施。涵盖包括船舶设计、施工、设备、人员配备、操作和处理等方面,确保这些方面的安全、环保、节能、安全。

4. 海洋污染的危害有哪些英语作文

海洋被称为“蓝色的油田”,“天然的鱼仓”的别称。对我们有很大的帮助。

  虽然大海占地球的71%,但我们也要保护它。目前海洋正受到我们人类的一些破坏,例如;向海洋排放污水,石油泄漏……这些现象导致海内大量的鱼死掉,严重的还发生赤潮。赤潮是海洋中一些微藻,原生动物或细菌发性增殖或聚集,引起水体变色或对海洋中其他生物产生危害的一种生态异常现象。赤潮是世界性公害。

  海洋是地球上相对稳定的生态系统,然而随着全球工业的发展,海洋污染日益严重,造成局部海域鱼类等海洋生物大量死亡,对海洋的生态平衡构成了危害。全球海洋是相互连通的一个整体,一个海域污染了,往往会扩散到周边海域,甚至有的后期效应还会波及全球。你们不为世界想想也为你们的生活想想呀。

  海洋真的能为我们做很多事,它就像一位母亲,哺育着我们。如果你“伤害”“母亲”那么你就是一个……开发利用海洋,是解决当前人类社会面临的人口膨胀,环境恶化,资源短缺等系列难题的有效途径。

  让我们一起保护大海吧!为了我们的世界,为了我们的地球,为了我们的家。

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.

Huaihe basin in many areas of cancer incidence rate than the normal area than 10 times to hundreds of times, some villages in 2/3 of hepatomegaly. At the same time, due to the pollution of the estuary, anadromous fish resources has been damaged, the sharp drop in output, part of the in

答案D

海洋石油污染不仅影响海洋生物的生长、降低海滨环境的使用价值、破坏海岸设施,还可能影响局部地区的水文气象条件和降低海洋的自净能力。据实测,每滴石油在水面上能够形成 0.25平方米的油膜,每吨石油可能覆盖5×106平方米的水面。油膜使大气与水面隔绝,减少进入海水的氧的数量,从而降低海洋的自净能力。油膜覆盖海面还会阻碍海水的蒸发,影响大气和海洋的热交换,改变海面的反射率,减少进人海洋表层的日光辐射,对局部地区的水文气象条件可能产生一定的影响。海洋石油污染的最大危害是对海洋生物的影响,油膜和油块能粘住大量鱼卵和幼鱼,使鱼卵死亡、幼鱼畸形,还会使鱼虾类产生石油臭味。
