1. 海洋被污染的危害
你好，给你提供几条概括性的影响危害，具体的自己发挥一下。
1.污染影响：工业废水（如海洋石油开发、炼油厂、排海工程、海岸工程、远洋运输危险货等）
2.生态影响 ：对海洋生态影响，影响生物量、生物多样性、影响珍稀濒危海洋生物的
栖息地、食源地、迁徙、繁殖）,有可能引发赤潮。
总之，环境污染后作为地表水和地下水最终受纳水体的海洋，因其环境容量局部海域有限（尤其是海湾或者封闭海域），在大量污染物质进入海洋环境后不能够很快的进行稀释净化，污染物累积进而出现各种危害效应。
2. 海洋污染的危害及措施
人类对海洋的破坏主要是污染海洋环境，海洋污染物依其来源、性质和毒性，可分为以下几类：
1、石油及其产品（见海洋石油污染）。
2、金属和酸、碱。包括铬、锰、铁、铜、锌、银、镉、锑、汞、铅等金属，磷、砷等非金属，以及酸和碱等。它们直接危害海洋生物的生存和影响其利用价值。
3、农药。主要由径流带入海洋。对海洋生物有危害。
4、放射性物质。主要来自核爆炸、核工业或核舰艇的排污。
5、有机废液和生活污水。由径流带入海洋。极严重的可形成赤潮。
6、热污染和固体废物。主要包括工业冷却水和工程残土、垃圾及疏浚泥等。前者入海后能提高局部海区的水温，使溶解氧的含量降低 ，影响生物的新陈代谢，甚至使生物群落发生改变；后者可破坏海滨环境和海洋生物的栖息环境。扩展资料海洋防止海洋污染的措施主要有：海洋开发与环境保护协调发展，立足于对污染源的治理；对海洋环境深入开展科学研究；健全环境保护法制，加强监测监视和管理；建立海上消除污染的组织；宣传教育；加强国际合作，共同保护海洋环境。1、海洋开发与环境保护协调发展，立足于对污染源的治理；2、对海洋环境深入开展科学研究；3、健全环境保护法制，加强监测监视和管理；4、建立海上消除污染的组织；5、大力宣传教育和科学6、加强国际合作，共同保护海洋环境。

飞逝的礁石读后感
海边有块礁石，涨潮时没入水中，退潮后露出海面。
退潮了，海滩上坐着两个人，一个是世居海边的年长者，一个是刚搬进海边别墅的年轻人。年轻人提着小桶跟赶海的工具要到露出水面的礁石上赶海。
“年青人，别去了，那上面什么也不。”年长者提示他。
“不会吧？这块礁石不是叫蛎子石吗？怎么会没有海蛎子？”
年轻人不解。
讲起蛎子石的故事。于是年长者颇有兴趣地说：“这块礁石叫蛎子石不假，早些年那上面长满了海蛎子，多到什么水平？这么跟你说吧，全部礁石上全长满了海蛎子，年年采年年有，每天采每天有，凌晨采早晨有，傍晚采薄暮有，就像神话传说中的聚宝盆。再说那海蛎子个头大，味道鲜，弄回家下面条、炒鸡蛋，那个滋味，今天想想都流口水。后来产生了天然灾祸，很多处所饿逝世了人，就是这块蛎子石，救了我们全村人的命。再后来城市越来越大，都盖到咱们村了，我们祖祖辈辈住的冬暖夏凉的海带草屋子拆了，盖成了高楼大厦，冒着臭味的黑水、黄水一个劲儿地往海里涌，这海再大也抗不住这么折腾。鱼跑远了，跑到深海里去了。海蛎子死了，光剩下了海蛎子皮。有一年，我下海游泳，游到蛎子石这儿想站一站，歇一歇，没想到，让海蛎子皮割得我双脚流血。我想，也该，这也算是大海对人的赏罚吧！谁叫你们不尊敬年夜海？”
年长者的故事讲完了，年轻人的嘴里吐出一声无奈的叹气。
4. 海洋被污染的危害有哪些
污水给鱼儿带来的只有死亡，如果人们吃了被污染的海里的鱼，大多数会生病的就海洋污染而言，是个大问题呀！海洋生物物种一旦遭难，生态就会失去平衡，也许会就此产生新物种来适应这种恶劣环境也说不定。但最大的可能就是愈演愈烈，最终地球将会成为一颗“死亡星球”。到时我们就惨了，还是现在好好保护吧。
5. 海洋污染的危害性
海洋中漂浮着逾5万亿件污染性塑料。大太平洋垃圾带正在持续扩大。我们每从海洋中取出一磅金枪鱼，就要放回两磅塑料。因此，我们亟需大胆的干预措施来减少塑料污染。我们每个人都可以贡献自己的力量，例如拒绝使用吸管、餐具和食品包装容器等一次性塑料。这些东西在我们的生命中只存在几秒钟，但随后可能会在海洋中循环好几个世纪，造成重大的危害。
6. 海洋污染的危害有哪些
来自长江和省内6大水系所携带的大量工农业废水和生活污水排入海中，使我省87％的近岸海域受到不同程度的污染，基本已无I类海水，沿海特别是河口海水中无机氮和无机磷严重超标，海水中磷酸盐合量在沿海省、自治区和直辖市中排居首位。
近岸海底沉积物中氮、磷超标严重，成为海水二次污染的潜在危害源。另外，个别海域（如杭州湾和舟山海域）船舶排污及碰撞漏油，海上石油开采溢油等加剧了近岸海域的污染，有机污染和重金属也对海水水质产生明显的影响。
海洋灾害频繁——每年发生大小赤潮近20次
我省是风暴潮、赤潮等海洋灾害最为严重的省份之一。每年因台风给我省海洋渔业造成的直接经济损失在数十亿元以上。由于海水水质下降和富营养化，导致赤潮灾害发生的频率逐年上升，给我省的海洋经济带来巨大的损失，近年来，每年发生的大小赤潮灾害近20次，年直接经济损失达数亿元。
围海造地——许多珍稀濒危野生生物绝迹，破坏生态
我省沿海滩涂资源359．04万亩，主要分布在钱塘江和杭州湾两岸，以及各海湾。由于不合理的围海造地，使沿海自然滩涂湿地面积缩减，不仅破坏了多种鸟类的栖息地，也使重要的经济鱼、虾、蟹和贝类生息、繁衍场所消失，许多珍稀濒危野生生物绝迹，而且大大降低了滩涂湿地调节气候、储水分洪、抵御风暴潮、净化地表径流及护岸保田等的能力，同时改变了海区的水动力方向，加速了航道和港口的淤积。
海洋食物链已经遭到严重破坏——经济鱼类资源大幅度降低
随着海洋开发话动的增多，海洋生态环境遭受破坏，使生物多样性衰减，某些生物种类已近绝迹，传统的经济鱼类资源大幅度降低，再也形不成渔汛，海洋食物链已经遭到严重破坏。东海生态系统中的主要经济物种严重衰竭，整体结构发生显著变异，系统内部自我调节的能力受到严重损害。
请勿将废水和生活垃圾直接排入海中
造成海水如此恶劣的污染源主要有陆上和海上两大类。陆上污染源主要是工业污水、居民的生活废水以及农田中使用的农药通过河流流入大海，沿海企业和居民直接将污水和废水排入海中。海上的污染源主要有船舶上和港口的油污和生活废水，养殖场、海洋工程、海岸工程产生的污染。
为了使我们的海域不再受污染，省有关部门已经颁布了一系列的政策法规对海域污染进行了治理。同时也提醒沿海的居民不要将废水和生活垃圾直接排入海中，出海的渔民应该把该回收的都要回收，而不要一丢完事。

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
