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.
海洋污染英語作文六：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
3. 海洋垃圾危害圖片
具體如下：
1、垃圾污染
工業(yè)冷卻水和工程殘土,、垃圾及疏浚泥等,。前者入海后能提高局部海區(qū)的水溫，使溶解氧的含量降低 ,，影響生物的新陳代謝,，甚至使生物群落發(fā)生改變；后者可破壞海濱環(huán)境和海洋生物的棲息環(huán)境,。
2,、噪聲污染
利用天然聲納進(jìn)行導(dǎo)航和捕獵，讓無脊椎動(dòng)物深受其害,?？碧酱a(chǎn)生的聲音污染對頭足類動(dòng)物以及其他海洋動(dòng)物的生存造成不利影響。
3,、過度捕撈
人類的捕魚活動(dòng)導(dǎo)致海洋中生存的某種魚類種群不足以繁殖并補(bǔ)充種群數(shù)量?，F(xiàn)代漁業(yè)捕獲的海洋生物已經(jīng)超過生態(tài)系統(tǒng)能夠平衡彌補(bǔ)的數(shù)量，結(jié)果使整個(gè)海洋系統(tǒng)生態(tài)退化,。
4,、冰川融化
由于冰蓋的融化，奇特的低鹽度海水正在慢慢的消失,，截止到2002年,， 96%的低鹽度棲居環(huán)境已經(jīng)消失殆盡。大部分以冰川徑流作為供水源的地區(qū)將會(huì)發(fā)生嚴(yán)重的缺水危機(jī),。
5,、石油泄漏污染
石油污染在海洋表面形成面積廣大的油膜，阻止空氣中的氧氣向海水中溶解,，同時(shí)石油的分解也消耗水中的溶解氧,，造成海水缺氧，對海洋生物產(chǎn)生危害,，并禍及海鳥和人類,。
4. 海洋垃圾危害的結(jié)尾
人類給海洋帶來的壞處：
一、過度捕撈,，海洋生物多樣性對人類生存關(guān)系重大,，但是正面臨日益增長的巨大危險(xiǎn)，漁場耗竭是最令人關(guān)切的事項(xiàng)之一,。
二、人類活動(dòng)對海洋的污染對海洋生物的危害,。
人類活動(dòng)而直接或間接進(jìn)入海洋環(huán)境,，并能產(chǎn)生有害影響的物質(zhì)或能量。人們在海上和沿海地區(qū)排污可以污染海洋，而投棄在內(nèi)陸地區(qū)的污物亦能通過大氣的搬運(yùn),，河流的攜帶而進(jìn)入海洋,。海洋中累積著的人為污染物不僅種類多、數(shù)量大,，而且危害深遠(yuǎn),。
5. 海洋垃圾危害視頻
一、海洋中的塑料垃圾主要有三個(gè)來源：
1.暴風(fēng)雨把陸地上掩埋的塑料垃圾沖到大海里;
2.海運(yùn)業(yè)中的少數(shù)人缺乏環(huán)境意識(shí),，將塑料垃圾倒入海中;
3.各種海損事故,，貨船在海上遇到風(fēng)暴，甲板上的集裝箱掉到海里,，其中的塑料制品就會(huì)成為海上“流浪者”,。
二、海洋垃圾危害：
海洋垃圾不僅會(huì)造成視覺污染,，還會(huì)造成水體污染,，造成水質(zhì)惡化。
海洋中最大的塑料垃圾是廢棄的魚網(wǎng),，它們有的長達(dá)幾英里,，被漁民們稱為“鬼網(wǎng)”。在洋流的作用下,，這些魚網(wǎng)絞在一起,，成為海洋哺乳動(dòng)物的“死亡陷阱”，它們每年都會(huì)纏住和淹死數(shù)千只海豹,、海獅和海豚等,。其他海洋生物則容易把一些塑料制品誤當(dāng)食物吞下。
塑料垃圾還可能威脅航行安全,。廢棄塑料會(huì)纏住船只的螺旋槳,，特別是被稱為“魔瓶”的各種塑料瓶，它們會(huì)損壞船身和機(jī)器,，引起事故和停駛,，給航運(yùn)公司造成重大損失。
浩瀚南海碧藍(lán)的海水,，潔白的沙灘,，良好的生態(tài)，令人心碎,。然而,，快餐盒、塑料袋,、漁網(wǎng)等海洋垃圾不時(shí)漂浮于海面,，污染了美麗的南海,。
“海洋垃圾已污染了我們的藍(lán)色家園，對南海海洋生態(tài)構(gòu)成一定威脅,?！焙Ｄ蠋煼洞髮W(xué)教授畢華如是說。
畢華提供的一張死亡海鳥圖片著實(shí)令人觸目驚心：一只碩大的海鳥慘死于沙灘上,，解剖后,，海鳥腹中依稀可見一些塑料垃圾。
“綠色和平”組織發(fā)現(xiàn)至少267種海洋生物因誤食海洋垃圾或者被海洋垃圾纏住而備受折磨,，并導(dǎo)致其死亡,，這對海洋生物來說是致命。另外,，海洋垃圾可通過生物鏈危害人類,，如重金屬和有毒化學(xué)物質(zhì)可通過魚類的食入而在體內(nèi)富集，人類吃了這些魚類勢必對人體健康構(gòu)成威脅,。
人類海岸活動(dòng)和娛樂活動(dòng),，航運(yùn)、捕魚等海上活動(dòng)是海灘垃圾的主要來源,。據(jù)統(tǒng)計(jì),，塑料和聚苯乙烯類制品占海洋漂浮垃圾的90%。
專家們認(rèn)為,，海洋垃圾正在吞噬著人類和其他生物賴以為生的海洋,。如再不采取措施，海洋將無法負(fù)荷,，人類和其他生物都將無法生存,。
三、相應(yīng)措施
海洋垃圾監(jiān)測
為了掌握海洋垃圾的種類,、數(shù)量和來源,，并評估其演變趨勢，在監(jiān)測的同時(shí)清除海洋垃圾,，并加強(qiáng)公眾教育,。
海洋垃圾清除
清理海洋塑料垃圾的方法可按照區(qū)域分為海岸、海灘收集法和海上船舶收集法,。其中海岸,、海灘收集法要比海上船舶收集法簡單許多，因?yàn)槔坏┻M(jìn)入海洋便會(huì)具備持續(xù)性強(qiáng)和擴(kuò)散范圍廣兩個(gè)特點(diǎn),，這兩個(gè)特點(diǎn)加大了海上船舶收集垃圾的難度,。同時(shí)，海上收集垃圾時(shí)對船只的技術(shù)要求也很高,。船只要能形成高速水流通道,，同時(shí)還要具備翻斗設(shè)備和可升降聚集箱,，這樣才能將漂浮在海上的塑料垃圾聚集起來。
韓國漢城數(shù)字論壇發(fā)出聲明,，將在2016年啟動(dòng)全球海洋塑料垃圾清理行動(dòng)。數(shù)百萬噸的塑料進(jìn)入海洋,，影響了大量的海鳥和海洋哺乳動(dòng)物的生活,，對人類健康也產(chǎn)生很大的負(fù)面影響。有毒的化學(xué)物質(zhì)(包括多氯聯(lián)苯和滴滴涕)被塑料吸附,，濃度可增加100萬倍,。全球海洋塑料垃圾清理行動(dòng)第一階段業(yè)務(wù)試點(diǎn)部署，將在日本和韓國之間沿?？缭?000米的水域展開,，運(yùn)行歷時(shí)至少兩年，目標(biāo)是接近到對馬群島海岸附近,。而在未來5年的一系列大規(guī)模的任務(wù)中,，海洋清理行動(dòng)還將在夏威夷和加利福尼亞之間部署100公里長的清理系統(tǒng)，以清除約一半的泛太平洋垃圾帶,。
加強(qiáng)公眾教育
海上航行的船員們不愿將垃圾帶回港口,，也不愿打撈起扔在海洋中的垃圾。因此一些船員選擇將他們的垃圾丟棄在海上,。加強(qiáng)海洋垃圾傾倒罰款,，可以有效地阻止這一做法。例如在1993年美國豪華游輪"帝王公主號"因?yàn)閮A倒20個(gè)垃圾袋到海里被罰款50萬美元,。這個(gè)水平的罰款對隨意傾倒海洋廢棄物行為具有威懾力,。
建立創(chuàng)收項(xiàng)目
將回收及循環(huán)利用海洋污染物連接起來，尤其是在世界一些最貧窮的地區(qū),。 例如,，東非一些小規(guī)模項(xiàng)目能創(chuàng)造工作機(jī)會(huì)并減少海洋垃圾水平，這些項(xiàng)目將會(huì)進(jìn)一步推進(jìn),。
6. 海洋垃圾危害國內(nèi)研究
海洋主要給人類提供的物產(chǎn)有：海洋食品(魚,、蝦、海帶等),海鹽,、礦物資源(如鈾,、銀、金,、銅等),。
海洋還有其他功能:調(diào)節(jié)氣候(吸收二氧化碳)、蒸發(fā)水分有利降雨,、提供能源(潮汐能可以利用來發(fā)電),。引起海洋污染的原因主要有:油船泄漏,、傾倒工業(yè)廢料和生活垃圾、生活污水直接排進(jìn)海洋,。海洋污染給人類和海洋帶來許多危害,它使海洋食品中聚積毒素,人食用后會(huì)得?。皇购．a(chǎn)減少,危及人類的食物源;使浮游生物死亡,海洋吸收二氧化碳能力減低,加速溫室效應(yīng),；使海洋生物死亡或發(fā)生畸形,改變整個(gè)海洋的生態(tài)平衡,。
人類為保護(hù)海洋正在做出種種不懈的努力,包括禁止向海洋傾倒工業(yè)廢料和生活垃圾、生活污水處理之后再排放入海,。
