1. 不同海洋生物的介绍作文
海底世界，千姿百态，鱼成群结队地在珊瑚丛中穿来穿去，好看极了。
有的全身布满彩色的条纹；有的头上长着一簇红缨；有的周身像插着好些扇子，游动的时候飘飘摇摇；有的眼睛圆溜溜的，身上长满了刺，鼓起气来像皮球一样圆。
各种各样的鱼多得数不清，最有趣的要算海龟了。
每年四五月间，庞大的海龟成群爬到沙滩上来产卵。
海鸥有的飞在半空，有的贴近水面，锐利的眼睛紧紧地盯住海面上冒出的一个个水泡泡。
要是有小鱼浮出水面，就用尖尖的长嘴把它叼起来，与蓝天碧海构成一幅幅美丽的画卷！

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.

10. 不同海洋生物的介绍作文怎么写
水滴鱼：水滴鱼又名忧伤鱼或软隐棘杜父鱼、波波鱼，由于长着一副哭丧脸，被称为“全世界表情最忧伤”的鱼。这种海底怪鱼确实有理由郁闷：科学家警告称，由于深海捕捞作业，水滴鱼正遭受灭绝的威胁。水滴鱼生活在澳大利亚和塔斯马尼亚沿岸，最深达1200米的海底当中，由于很难达到这种鱼的栖息地，所以很少被人类所发现。 水滴鱼（Blobfish）身体呈凝胶状，可长到12英寸（约合30.5厘米）。
翻车鱼：老司机翻车鱼长得很离奇，它体短而侧扁，背鳍和臀鳍相对而且很高，尾鳍很短，看上去好像被人用刀切去一样。因此，它的普通名称也叫头鱼。翻车鱼游泳速度缓慢。它生活在热带海中，身体周围常常附着许多发光动物。它一游动，身上的发光动物便会发出明亮的光，远远看去像一轮明月，故又有“月亮鱼”之美名。翻车鱼这种头重脚轻的体型很适宜潜水，它常常潜到深海捕捉深海鱼虾为食。
烛光鱼：会发光的不只是有萤火虫、电鳐，还有烛光鱼。烛光鱼其腹部和腹侧有多行发光器，犹如一排排的蜡烛，故名烛光鱼深海的光头鱼头部背面扁平，被一对很大的发光器所覆盖，该大型发光器可能就起视觉的作用。PS：鱼类发光实际上是由一种特殊酶的催化作用而引起的生化反应。
蝠鲼（Mobula）：又称“魔鬼鱼”。魔鬼鱼是一种庞大的热带鱼类，学名叫前口蝠鲼。它的个头和力气常使潜水员害怕，因为只要它发起怒来，只需用它那强有力的“双翅”一拍，就会碰断人的骨头，致人于死地。所以人们叫它“魔鬼鱼”。有的时候蝠鲼用它的头鳍把自己挂在小船的锚链上，拖着小船飞快地在海上跑来跑去，使渔民误以为这是“魔鬼”在作怪，实际上是蝠鲼的恶作剧。
