1. 海洋污染的原因以及解決措施

防止海洋污染的措施主要有：

1.海洋開(kāi)發(fā)與環(huán)境保護(hù)協(xié)調(diào)發(fā)展,立足于對(duì)污染源的治理；

2.對(duì)海洋環(huán)境深入開(kāi)展科學(xué)研究,；

3.健全環(huán)境保護(hù)法制,加強(qiáng)監(jiān)測(cè)監(jiān)視和管理,；

4.建立海上消除污染的組織,；

5.宣傳教育,；

6.加強(qiáng)國(guó)際合作,共同保護(hù)海洋環(huán)境.

2. 海洋污染原因危害措施

就目前的開(kāi)采技術(shù)而言,，基本上無(wú)論是哪種方法,，都是促使可燃冰中天然氣與水的分離,，要促使其分離,，必然要改變其溫度及壓力環(huán)境,，這樣就可能會(huì)產(chǎn)生一系列不可預(yù)知的環(huán)境問(wèn)題，如溫室效應(yīng)的加劇,、海洋生態(tài)的變化及引起地質(zhì)災(zāi)害的可能,。

可燃冰的成分主要是甲烷，甲烷是一種強(qiáng)溫室氣體,，對(duì)大氣輻射平衡的影響僅次于CO2,。

目前探明全球可燃冰儲(chǔ)量的甲烷是大氣圈中甲烷的5000倍，在開(kāi)采的過(guò)程中,，即使如此巨大的甲烷總量哪怕是0.5%進(jìn)入大氣層,，對(duì)全球變暖的影響也是難以估量的，如果開(kāi)采中稍有不慎,，則必然會(huì)加劇溫室效應(yīng),。在海洋中開(kāi)采可燃冰帶來(lái)的環(huán)境問(wèn)題更多，一方面甲烷如果直接進(jìn)入海水中，則會(huì)很快發(fā)生微生物的氧化反應(yīng),，從而會(huì)改變海水的化學(xué)屬性,，如果大量進(jìn)入，其氧化過(guò)程中會(huì)消耗海水中大量的氧氣,，使得海洋缺氧,，這樣勢(shì)必會(huì)加速海洋生物的死亡；

另一方面大量直接進(jìn)入海洋的甲烷還可能會(huì)加速海洋氣化及海嘯,，導(dǎo)致海水加速流動(dòng)及氣壓卷吸,，會(huì)嚴(yán)重危害海面船只及作業(yè)平臺(tái)的安全，甚至強(qiáng)對(duì)流的海水會(huì)直入空中,，影響航空及陸地建筑的安全,。

在開(kāi)采可燃冰的過(guò)程中，會(huì)分解大量的水,，這些水會(huì)稀釋巖層空間,，使得地層結(jié)構(gòu)穩(wěn)定性變差，容易引發(fā)地質(zhì)災(zāi)害,。

在海洋環(huán)境中,，無(wú)論是減壓分解還是激熱分解，都會(huì)導(dǎo)致海底陸坡區(qū)的穩(wěn)定性下降,，嚴(yán)重則會(huì)發(fā)生海底坍塌,，如毀壞海底輸電或通信電纜和海洋石油鉆井平臺(tái)等設(shè)施。

就目前的開(kāi)采方法來(lái)看,，無(wú)論是哪種方法都不能單獨(dú)實(shí)施,，必須是幾種方法的結(jié)合，如果使用二氧化碳置換法,、化學(xué)試劑減壓法與其他方法的結(jié)合實(shí)施,，則勢(shì)必會(huì)產(chǎn)生新的問(wèn)題，這些化學(xué)試劑及二氧化碳注入到地下后,，會(huì)嚴(yán)重污染地下水源,。

7. 海洋污染的原因以及解決措施英語(yǔ)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!

海洋污染英語(yǔ)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!

海洋污染英語(yǔ)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.

海洋污染英語(yǔ)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.

海洋污染英語(yǔ)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.

海洋污染英語(yǔ)作文六：Sea Pollution

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
