1. 海洋垃圾污染
每年約有1000萬(wàn)噸塑料被倒入海洋,,由此造成的污染一直備受關(guān)注,。我們可見的海洋漂浮塑料其實(shí)僅占其中的1%,剩下的99%被認(rèn)為流向了深海,,但具體去向一直是未解之謎,。近日,發(fā)表在《科學(xué)》雜志的一項(xiàng)研究試圖回答了這一問題,。
以下回答來(lái)源于《返樸》
圖片來(lái)源:europeanscientist.com/en/environment/ocean-currents-create-microplastic-hotspots-deep-in-the-mediterranean/
研究者收集了地中海海底的沉積物,,發(fā)現(xiàn)了有報(bào)告以來(lái)最高含量的微塑料——海底僅1平方米的薄層中就有多達(dá)190萬(wàn)個(gè)微塑料碎片,這一驚人的數(shù)字可謂遠(yuǎn)遠(yuǎn)超乎人們想象,。研究團(tuán)隊(duì)在實(shí)驗(yàn)室中分離微塑料進(jìn)行計(jì)數(shù)和紅外光譜分析,,并與深海洋流模型及海底測(cè)繪相結(jié)合,以展示深海洋流如何影響微塑料分布,。
研究表明,,深海洋流將微塑料碎片輸送到海底。微塑料并非均勻分布,,而是被深海洋流裹挾,、富集在沉積物中,進(jìn)而分布在特定海域,。由于洋流還攜帶氧氣和營(yíng)養(yǎng),,故相應(yīng)區(qū)域可能還容納著消耗吸收微塑料的生態(tài)系統(tǒng),。
微塑料被海底洋流收集攜帶,進(jìn)入海底沉積 | 圖片來(lái)源:參考文獻(xiàn)[2]
本研究首次將深海洋流與海底微塑料濃度聯(lián)系起來(lái),,將有助于預(yù)測(cè)深海微塑料富集區(qū)的分布,,研究微塑料對(duì)海洋生物的影響。正如研究負(fù)責(zé)人之一,、美國(guó)國(guó)家海洋學(xué)中心的邁克·克萊爾(Mike Clare)博士所說,,“海底洋流研究可幫助尋找深海‘失蹤’的微塑料,。研究結(jié)果也強(qiáng)調(diào)了政策干預(yù)的必要性,,我們應(yīng)限制塑料流入自然環(huán)境,盡量減少對(duì)海洋生態(tài)系統(tǒng)的影響,?!?/p>

2. 海洋垃圾污染的危害
有一天,一條小魚在海里自由自在地游來(lái)游去,。忽然,,很多的垃圾撲面而來(lái),于是,,小魚拿起一把舊的雨傘撐起來(lái),,它害怕垃圾會(huì)像冰雹一樣砸到雨傘上。這些垃圾有臭氣熏天的夾子和馬桶,,有很臟的海綿,,有舊的酒瓶,有被狗咬過的骨頭,,有破舊的梳子,,有臭氣熏天的襪子,大海成了海底垃圾場(chǎng),。小魚覺得身上的魚鱗在往下脫落,,它又覺得頭昏腦脹很難受。它好像得了癌癥的患者和垂死掙扎的人,,是垃圾污染了小魚的生命,。
這是我看到的一幅漫畫。我覺得漫畫里的小魚好可憐呀,!我們要保護(hù)大海,,要給小魚一個(gè)溫暖、幸福,、快樂的家。
3. 海洋垃圾污染繪畫
如果我們要完成一幅海洋畫,,那么我們就畫的很簡(jiǎn)單,,我們都知道在海洋里面有各種各樣的魚類,,還有各種各樣的珊瑚,以及各種各樣的旗袍,,還有各種各樣的貝殼類,,那么我們就可以去在我們的作品當(dāng)中把它完成好,然后涂上我們藍(lán)藍(lán)的顏色就可以了,。
4. 海洋垃圾污染現(xiàn)狀和數(shù)據(jù)
世界上每年向海洋中傾倒的廢棄物多達(dá)1200萬(wàn)噸,,每年都有1200萬(wàn)噸的垃圾最終流入了海洋,預(yù)計(jì)至2040年將會(huì)增加兩倍,。
公眾環(huán)境研究中心主任馬軍在接受《每日經(jīng)濟(jì)新聞》記者采訪時(shí)稱,,海洋塑料垃圾污染在水里,但是問題在陸地,。一定要嚴(yán)控陸源塑料的排放,,通過減量、回收,、再利用的路徑來(lái)推進(jìn)陸源塑料垃圾治理,,其中,加強(qiáng)垃圾分類能起到非常核心的作用,。
5. 海洋垃圾污染英語(yǔ)
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(yǔ)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(yǔ)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(yǔ)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(yǔ)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

2020年世界海洋日的主題是什么:為可持續(xù)海洋創(chuàng)新
聯(lián)合國(guó)于第63屆聯(lián)合國(guó)大會(huì)上將每年的6月8日確定為“世界海洋日”,。2009年,,聯(lián)合國(guó)將首個(gè)世界海洋日的主題確定為“我們的海洋,我們的責(zé)任”,;今年,,作為生物多樣性“超級(jí)年”的2020年,綠會(huì)國(guó)際部關(guān)注到世界海洋日官網(wǎng)已公布最新的海洋日主題——“為可持續(xù)海洋創(chuàng)新”,。
一年一度的世界海洋日,,旨在提醒人們海洋和海洋資源對(duì)于日常生活的重要性。海洋是地球的肺,,人類所呼吸的氧氣大多由海洋提供,。海洋日希望通過讓公眾了解人類活動(dòng)軌跡對(duì)海洋的影響,從而發(fā)起全球性的“海洋全民運(yùn)動(dòng)”,,動(dòng)員并團(tuán)結(jié)全世界民眾參與到世界海洋資源的可持續(xù)管理當(dāng)中,。同時(shí),海洋也是食物及藥品的主要來(lái)源,,更是生物生態(tài)圈的關(guān)鍵組成部分,。聯(lián)合國(guó)秘書長(zhǎng)潘基文曾致辭指出:“人類活動(dòng)正在使海洋世界付出可怕的代價(jià),個(gè)人和團(tuán)體都有義務(wù)保護(hù)海洋環(huán)境,,認(rèn)真管理海洋資源,。”
我們生活的地球擁有著非常豐富的海洋資源,,海洋生物資源,、海水化學(xué)資源、海洋礦產(chǎn)資源,、海洋能源等都對(duì)人類的生存,、發(fā)展和文明有著重大影響。然而,,隨著各國(guó)各地區(qū)社會(huì)生產(chǎn)力和經(jīng)濟(jì)的告訴發(fā)展,,海洋資源受到了不同程度的污染和破壞,這些污染情況的日益加劇給人類生存和發(fā)展帶來(lái)極為不利的后果,。各國(guó)政府和機(jī)構(gòu)都高度關(guān)注海洋環(huán)境問題,,國(guó)際社會(huì)也相繼制訂了一系列的公約,但海洋環(huán)境形勢(shì)仍是非常嚴(yán)峻,。
