1. 海洋垃圾污染

每年约有1000万吨塑料被倒入海洋,由此造成的污染一直备受关注。我们可见的海洋漂浮塑料其实仅占其中的1%,剩下的99%被认为流向了深海,但具体去向一直是未解之谜。近日,发表在《科学》杂志的一项研究试图回答了这一问题。

研究者收集了地中海海底的沉积物,发现了有报告以来最高含量的微塑料——海底仅1平方米的薄层中就有多达190万个微塑料碎片,这一惊人的数字可谓远远超乎人们想象。研究团队在实验室中分离微塑料进行计数和红外光谱分析,并与深海洋流模型及海底测绘相结合,以展示深海洋流如何影响微塑料分布。

研究表明,深海洋流将微塑料碎片输送到海底。微塑料并非均匀分布,而是被深海洋流裹挟、富集在沉积物中,进而分布在特定海域。由于洋流还携带氧气和营养,故相应区域可能还容纳着消耗吸收微塑料的生态系统。

本研究首次将深海洋流与海底微塑料浓度联系起来,将有助于预测深海微塑料富集区的分布,研究微塑料对海洋生物的影响。正如研究负责人之一、美国国家海洋学中心的迈克·克莱尔(Mike Clare)博士所说,“海底洋流研究可帮助寻找深海‘失踪’的微塑料。研究结果也强调了政策干预的必要性,我们应限制塑料流入自然环境,尽量减少对海洋生态系统的影响。”

2. 海洋垃圾污染的危害

有一天,一条小鱼在海里自由自在地游来游去。忽然,很多的垃圾扑面而来,于是,小鱼拿起一把旧的雨伞撑起来,它害怕垃圾会像冰雹一样砸到雨伞上。这些垃圾有臭气熏天的夹子和马桶,有很脏的海绵,有旧的酒瓶,有被狗咬过的骨头,有破旧的梳子,有臭气熏天的袜子,大海成了海底垃圾场。小鱼觉得身上的鱼鳞在往下脱落,它又觉得头昏脑胀很难受。它好像得了癌症的患者和垂死挣扎的人,是垃圾污染了小鱼的生命。

这是我看到的一幅漫画。我觉得漫画里的小鱼好可怜呀!我们要保护大海,要给小鱼一个温暖、幸福、快乐的家。

如果我们要完成一幅海洋画,那么我们就画的很简单,我们都知道在海洋里面有各种各样的鱼类,还有各种各样的珊瑚,以及各种各样的旗袍,还有各种各样的贝壳类,那么我们就可以去在我们的作品当中把它完成好,然后涂上我们蓝蓝的颜色就可以了。

4. 海洋垃圾污染现状和数据

世界上每年向海洋中倾倒的废弃物多达1200万吨,每年都有1200万吨的垃圾最终流入了海洋,预计至2040年将会增加两倍。

公众环境研究中心主任马军在接受《每日经济新闻》记者采访时称,海洋塑料垃圾污染在水里,但是问题在陆地。一定要严控陆源塑料的排放,通过减量、回收、再利用的路径来推进陆源塑料垃圾治理,其中,加强垃圾分类能起到非常核心的作用。

5. 海洋垃圾污染英语

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

8. 海洋垃圾污染宣传语

2020年世界海洋日的主题是什么:为可持续海洋创新

联合国于第63届联合国大会上将每年的6月8日确定为“世界海洋日”。2009年,联合国将首个世界海洋日的主题确定为“我们的海洋,我们的责任”;今年,作为生物多样性“超级年”的2020年,绿会国际部关注到世界海洋日官网已公布最新的海洋日主题——“为可持续海洋创新”。

一年一度的世界海洋日,旨在提醒人们海洋和海洋资源对于日常生活的重要性。海洋是地球的肺,人类所呼吸的氧气大多由海洋提供。海洋日希望通过让公众了解人类活动轨迹对海洋的影响,从而发起全球性的“海洋全民运动”,动员并团结全世界民众参与到世界海洋资源的可持续管理当中。同时,海洋也是食物及药品的主要来源,更是生物生态圈的关键组成部分。联合国秘书长潘基文曾致辞指出:“人类活动正在使海洋世界付出可怕的代价,个人和团体都有义务保护海洋环境,认真管理海洋资源。”

我们生活的地球拥有着非常丰富的海洋资源,海洋生物资源、海水化学资源、海洋矿产资源、海洋能源等都对人类的生存、发展和文明有着重大影响。然而,随着各国各地区社会生产力和经济的告诉发展,海洋资源受到了不同程度的污染和破坏,这些污染情况的日益加剧给人类生存和发展带来极为不利的后果。各国政府和机构都高度关注海洋环境问题,国际社会也相继制订了一系列的公约,但海洋环境形势仍是非常严峻。
