1. 解决海洋问题的措施

据资料表明,海上污染的80%来自陆地,陆源污染物向海洋转移,是造成海洋污染的主要根源。

除此之外,来自大气层中的烟尘和一些化学物质也源源不断地归入海洋,某些国家沉放在深水区的放射性物质也有增无减等等。

如今的海洋再也承受不了日益加重的污染负担,人类不能等到海洋的蓝色消失后,再来控制污染、整治海洋。

当务之急是制定并实施保护海洋环境的具体措施。海洋环境保护是在调查研究的基础上,针对海洋环境方面存在的问题,依据海洋生态平衡的要求制定有关法规,并运用科学的方法和手段来调整海洋开发和环境生态间的关系,以达到海洋资源持续利用的目的。

总之,人类应该从失误中尽快觉悟,按自然规律办事,不断提高科学文化素养,树立科学发展观,健全必要的管理法规,依法治理,还海洋一个清洁的水体,让海洋造福人类。我们应该牢记:污染海洋,就是危害人类自己!保护海洋,就是拯救人类自己!

2. 解决海洋争端的方法有哪些

中国不仅有960万平方千米的陆地国土,还有300万平方千米的蔚蓝国土和海岸线。在21世纪一个波及全球的海洋经济时代来临之际,我们不能再漠视周边国家对我国海洋权益的侵犯。必须针对不同情况找到合理、有效的解决机制。只有这样我们才能拥有本属于我们自己的资源。

在解决争端的过程中我国首先应该加强海防,因为有实力才有谈判,国家的利益只能靠实力获得。没有强大的海军,周边国家未必愿意让出已经侵占到手的海洋权益。其次,我国在处理争端时应当唯国家利益是问,以合作为主,适当强硬。因为国家之间只有永恒的利益没有永恒的朋友。我国虽然需要一个安定的国际环境进行改革,但是不能为了一时的经济利益将海洋权益拱手让人。

3. 解决海洋争端的有效途径

长期以来,东亚合作得以顺利推进,很大程度上归功于东盟国家按照“东盟方式”搁置争议、增进共识、形成合力,这种精神也应为东亚合作各方所共同倡导和遵循。中国和东盟国家有足够的智慧和能力,在不受外部干扰的条件下,妥善处理包括领土和海洋权益争端在内的各种问题,维护东亚合作发展大局。

4. 解决海洋资源问题的措施

1、海洋矿物资源。海洋矿产资源,又名海底矿产资源,是海滨、浅海、深海、大洋盆地和洋中脊底部的各类矿产资源的总称。主要有石油、煤、铁、铝钒土、锰、铜、石英岩等。

2、海水化学资源。主要有氯、钠、镁、硫、碘、铀、金、镍等,它们溶解在海水中,其性质同海洋矿物资源一样,都是矿物资源(区别于生物资源)

3、海洋生物资源。又称海洋水产资源,指海洋中蕴藏的经济动物和植物的群体数量,是有生命、能自行增殖和不断更新的海洋资源。其特点是通过生物个体种和种下群的繁殖、发育、生长和新老替代,使资源不断更新,种群不断补充,并通过一定的自我调节能力达到数量相对稳定。

4、海洋动力资源。主要指海水运动过程中产生的潮汐能、波浪能、海流能及海水因温差和盐度差而引起的温差能与盐差能等。其特点为:①蕴藏量大,可再生。②能流分布不均、密度低。③能量多变,不稳定。

5. 解决海洋问题的措施英语作文

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.

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
