1. 发展海洋旅游
中国海洋大学旅游管理专业还是容易找到工作的。中国海洋大学属于211,本身学历就很好,旅游管理专业就业前景也是不错的,毕业后可以当导游,旅游咨询公司,公务员考试,景区的管理开发等相关工作。我周围很多旅游管理的同学,他们毕业后都能找到不错的工作。
2. 发展海洋旅游业的例子
2012年11月8号提出的,要求提高海洋资源开发能力,发展海洋经济,保护海洋生态环境,坚决维护国家海洋权益,建设海洋强国。
海洋经济,一般包括为开发海洋资源和依赖海洋空间而进行的生产活动,以及直接或间接开发海洋资源及空间的相关产业活动,由这样一些产业活动形成的经济集合均被视为现代海洋经济范畴。主要包括海洋渔业、海洋交通运输业、海洋船舶工业、海盐业、海洋油气业、滨海旅游业等。
3. 发展海洋旅游业的利与弊
1、海洋是一个完整的水体。海洋本身对污染物有着巨大的搬运、稀释、扩散、氧化、还原和降解等净化能力。但这种能力并不是无限的,当局部海域接受的有毒有害物质,超过它本身的自净能力时,就会造成该海域的污染。
2、我国目前经济发展的现状已经严重影响了生态环境的平衡,海洋产业的快速发展也造成了同样的问题。虽然海洋产业的发展极大的推动了我国经济的进步,但是海洋环境问题也变得更加突出。所以如果不能处理好海洋环境保护的问题,海洋产业的发展就会受到直接的影响,再间接地影响到海洋经济和国家经济的总体发展。也就是说海洋环境保护对于我国的经济发展是至关重要的。
3、 保障人类食物来源安全
从生物进化的角度分析,是海洋孕育了地球上的生命,是生命之母。人类也是水生生物不断进化的产物,海洋是地球上所以生物赖以生存的基本条件。
4、 为人类提供宜居的环境
海洋对气候具有强大的调节作用,沿海地区是地球上最适合人类居住的区域,自古以来人类都会有意识的选择靠近海洋的地区定居,如今沿海地区的人口数量更是爆炸式的增长,有些地区的人口数量已经超出了当地的人口承载极限。
人口数量的大幅增加给海洋环境带来了更大的压力,造成了海洋环境的破坏,这种结果反过来也影响了沿海居民的居住环境。因此海洋环境保护的另一重要内容便是通过各种手段解决沿海地区的人口压力,这样才能在人类和海洋之间建立起友好的关系,对破坏海洋环境的行为要严厉处罚,珍惜海洋为我们提供的宝贵的环境资源。
5、国家安全不仅仅是指维护国家主权和领土完整,保证国家不受侵犯,它还包括了生态环境安全,经济发展安全等等很多的内容,这些方面的国家安全问题虽然不如军事领域的国家安全看上去那么令人紧张,但是一旦国家生态环境出现问题就会从国家内部根本上对国家的方方面面产生严重的影响。

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.
海洋污染英语作文六: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
