1. 發(fā)展海洋旅游

中國海洋大學旅游管理專業(yè)還是容易找到工作的,。中國海洋大學屬于211,，本身學歷就很好，旅游管理專業(yè)就業(yè)前景也是不錯的,，畢業(yè)后可以當導(dǎo)游,，旅游咨詢公司,，公務(wù)員考試,，景區(qū)的管理開發(fā)等相關(guān)工作。我周圍很多旅游管理的同學,，他們畢業(yè)后都能找到不錯的工作,。

2. 發(fā)展海洋旅游業(yè)的例子

2012年11月8號提出的，要求提高海洋資源開發(fā)能力,發(fā)展海洋經(jīng)濟,保護海洋生態(tài)環(huán)境,堅決維護國家海洋權(quán)益,建設(shè)海洋強國,。

海洋經(jīng)濟,，一般包括為開發(fā)海洋資源和依賴海洋空間而進行的生產(chǎn)活動，以及直接或間接開發(fā)海洋資源及空間的相關(guān)產(chǎn)業(yè)活動,，由這樣一些產(chǎn)業(yè)活動形成的經(jīng)濟集合均被視為現(xiàn)代海洋經(jīng)濟范疇,。主要包括海洋漁業(yè)、海洋交通運輸業(yè),、海洋船舶工業(yè),、海鹽業(yè)、海洋油氣業(yè),、濱海旅游業(yè)等,。

3. 發(fā)展海洋旅游業(yè)的利與弊

1、海洋是一個完整的水體,。海洋本身對污染物有著巨大的搬運、稀釋,、擴散,、氧化、還原和降解等凈化能力,。但這種能力并不是無限的,，當局部海域接受的有毒有害物質(zhì)，超過它本身的自凈能力時,，就會造成該海域的污染,。

2、我國目前經(jīng)濟發(fā)展的現(xiàn)狀已經(jīng)嚴重影響了生態(tài)環(huán)境的平衡,，海洋產(chǎn)業(yè)的快速發(fā)展也造成了同樣的問題,。雖然海洋產(chǎn)業(yè)的發(fā)展極大的推動了我國經(jīng)濟的進步，但是海洋環(huán)境問題也變得更加突出,。所以如果不能處理好海洋環(huán)境保護的問題,，海洋產(chǎn)業(yè)的發(fā)展就會受到直接的影響，再間接地影響到海洋經(jīng)濟和國家經(jīng)濟的總體發(fā)展,。也就是說海洋環(huán)境保護對于我國的經(jīng)濟發(fā)展是至關(guān)重要的,。

3、 保障人類食物來源安全

從生物進化的角度分析,，是海洋孕育了地球上的生命,，是生命之母,。人類也是水生生物不斷進化的產(chǎn)物，海洋是地球上所以生物賴以生存的基本條件,。

4,、 為人類提供宜居的環(huán)境

海洋對氣候具有強大的調(diào)節(jié)作用，沿海地區(qū)是地球上最適合人類居住的區(qū)域,，自古以來人類都會有意識的選擇靠近海洋的地區(qū)定居,，如今沿海地區(qū)的人口數(shù)量更是爆炸式的增長，有些地區(qū)的人口數(shù)量已經(jīng)超出了當?shù)氐娜丝诔休d極限,。

人口數(shù)量的大幅增加給海洋環(huán)境帶來了更大的壓力,，造成了海洋環(huán)境的破壞，這種結(jié)果反過來也影響了沿海居民的居住環(huán)境,。因此海洋環(huán)境保護的另一重要內(nèi)容便是通過各種手段解決沿海地區(qū)的人口壓力,，這樣才能在人類和海洋之間建立起友好的關(guān)系，對破壞海洋環(huán)境的行為要嚴厲處罰,，珍惜海洋為我們提供的寶貴的環(huán)境資源,。

5、國家安全不僅僅是指維護國家主權(quán)和領(lǐng)土完整,，保證國家不受侵犯,，它還包括了生態(tài)環(huán)境安全，經(jīng)濟發(fā)展安全等等很多的內(nèi)容,，這些方面的國家安全問題雖然不如軍事領(lǐng)域的國家安全看上去那么令人緊張,，但是一旦國家生態(tài)環(huán)境出現(xiàn)問題就會從國家內(nèi)部根本上對國家的方方面面產(chǎn)生嚴重的影響。

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
