海洋污染作文1
河流、海洋、湖泊、水潭的污染越来越大。
人们乱扔垃圾入江河、湖海,原来美丽的河流瞬间变成了一条臭水沟,多少水生物死于我们乱扔垃圾的行为啊!
还有,我们建立这么多工厂,本来是对环境影响不大,可是,那些工厂却把不达标的污水、垃圾、铅、毒…倒入河流和海洋。
一些海洋生物吃了这些垃圾之后造成死亡,如:海鱼,一旦吃了垃圾身体就会飘浮在水面上身亡。
我们这是自己走向灭绝,因为我们未来会很发达,楼房会占领了森林和田地,那些能让我们食用的海洋生物也被我们逼它们走向绝境,也是在逼我们走向绝境。我们不应该乱扔垃圾和排放化学物质入江河,海洋等水地。
我下定决心要在假期和休息日时把水里的垃圾清理干净,坚持环保并向人们宣传环保意识,让我们的生存环境可持续健康发展。为了我们的家园更美丽,请大家关注海洋污染,行动起来,保护我们的母亲河!
海洋污染作文2
从小老师就教育我们,大海孕育了我们的生命,每一个地球人都应为保护海洋环境贡献自己的力量。
众所周知,海洋对我们每个人都很重要。它占据地球表面积的71%,远远的从太空看,地球就像一颗晶莹剔透的蓝色水晶球,这就是地球又被人们称为“水球”的原因。因而破坏海洋的行为会对整个地球造成影响。
放假的时候我最喜欢到海边玩啦,光者脚丫子在海滩上跑,很快海水就会漫上来,盖住一串串脚印,跑累了就看看大海,站在高高的礁石上眺望远方的海平线,海水蓝蓝的.调皮的拍打着海岸,勇敢的海鸟在海浪中穿梭,多希望这一刻永远印在脑海中!
可是最近污染海洋的新闻越来越多,每当看到这些新闻,我就为海洋担心,为人类的自私感到羞愧,为人类盲目追求经济增长造成海洋污染的后果感到愤怒。我越来越担心大海里的小生命会受到伤害,担心海鸟失去生存的家园,担心总有一天人类会受到大自然的报复。
海洋无私的帮助我们,我们却反过来破坏它,这不是老师教我们以怨报德的故事吗?所以我们不能忘了大海的贡献,我们应当爱护它,把它当母亲一样关心、呵护。当我们伤害了它,我们应当感到内疚,应当做出更多补偿。
小学生人小力量不小,我们可以从点滴小事做起,比如说把平时的零用钱攒起来捐给爱护海洋基金,可以在放假时去海边捡捡垃圾,可以向身边的人宣传保护海洋的知识……让我们行动起来,为保护海洋奉献自己的力量吧!
海洋污染作文3
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 20xx, 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 20xx.
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.

Since childhood, the teacher has taught us that the sea has nurtured our life, and every earth man should contribute his strength to the protection of the marine environment.
As we all know, the ocean is very important to all of us. It occupies 71% of the earth's surface area, far from the space, the earth is like a crystal clear blue crystal ball, this is the earth is also known as "water polo" reasons. The destruction of the oceans would therefore affect the entire planet.
During the holidays I most love to the seaside, the light foot on the beach. Soon the water will diffuse to cover a string of footprints, running tired to see the sea, standing on the high rocks overlooking the distant horizon, the sea blue naughty beat the shore, brave bird the shuttle in the surf, hope this moment forever in my mind!
But the latest marine pollution news more and more, when I see the news, I was worried about the sea, for human selfishness shame, anger is human blind pursuit of economic growth caused by the consequences of marine pollution. I am increasingly worried that small life in the sea will be hurt, worried that seabirds lost their homes to live, and that one day people will be punished by nature.
The selfless help us, but we in turn destroy it, this is not the teacher taught us the story of ingratitude? Therefore, we must not forget the contribution of the sea, we should take good care of it, and treat it as a mother, care and care. When we hurt it, we should feel guilty and should make more compensation.
Primary small power is not small, we can start from little things, such as the usual pocket money saved up to protect marine funds, while on holiday to the seaside to pick up trash, can promote the protection of the ocean to the side of the man's knowledge...... Let us take action and dedicate ourselves to the protection of the seas!
海洋污染作文5
以前,我们的海洋是那样的美丽,波光粼粼,令人心旷神怡,流连忘返。但现在呢!这些海洋已遭受严重污染,无论是亚龙湾,还是浏阳河,都可以看到成堆的垃圾,散发出难闻的味道。
那这又是因为什么造成的呢?这都只能怪我们自己。(.)它们主要是从油船与油井出来的原油,农田用的杀虫剂和化肥。工厂排出的污水,矿产流出的酸性溶液,它们使得大部分的海洋,湖泊受到污染,结果不但生物不能生长,就是鸟类和人类也可能因吃了这些生物而中毒死亡。这是一个难以置信但千真万确的数字,每24小时便有2.5万人(包括儿童)死亡于吃了被污染的海水里的鱼虾。还不仅仅这样,中国工程院院长,湖泊环境研究主席,科学家刘鸿量教授对全国
5500千米河段进行研究调查,报告显示,百分之二十三点三的河水段水质污染严重而不能用于灌溉,百分之四十五的河段里鱼虾绝迹,百分之八十五的河段不符合人类饮水用水标准量,而且河流自洁等生态功能也严重衰退,形势异常严峻。当我们的宇航员飞上太空,目睹我们的地球,映入眼帘的是一个晶莹的球体,上面蓝色和白色的纹痕相互交错。但是如果我们再这样让海水受到污染,那么蓝色会渐渐消失,地球将变得一片白!
为了我们有一个美好明天,为了我们的子孙后代能够更好的生活,让我们共同努力吧!
海洋污染作文6
我是一名海上环保小组的成员,保护海洋环境,定期对海上生态情况进行检查是我的任务。
一天早上,我和两名小组成员向往常一样坐上巡检船去海上巡查,当我们的船航行到澳大利亚新南威尔州的亚姆巴海岸线时,海水检验系统突然发出“嘟嘟嘟。”的报警声,我赶快调出电脑监控图像查看,一看屏幕我被吓了一跳,平时蓝蓝的大海不见了,一层层白色的泡沫堆积在海面上,随着波浪一起一伏,好像巨大浴缸中的泡泡浴。
浑浊带着泡沫的海水冲向海滩,冲打着岸边的度假者,人们惊慌的四散而逃。出事了?那白色的是什么东西?为什么会这样?会不会有危险?一连串的问题出现在我的脑海里。我马上把险情报告上级,上级指示我们搞清情况。
为了搞清原因我们决定亲手取一些泡沫作样本,走进变成“卡布奇诺咖啡”一般的大海,我和组员都捏着一把汗,不知这种不明物质对人体有多大危害。我们穿上蓝色的潜水服,戴上长长的塑胶手套和防护境,手里拿着两个实验玻璃瓶,潜到海下,我发现海面下的海水还是深蓝色的,比平时的海水浑浊许多,白色的泡沫只浮于海水表面,没有什么刺激的味道。我们很快取到样本,随后向总部发出信号,等待专家的到来。
经过专家一番仔细检验,发现这种不明的白色泡沫,是由于大量从河里流出的淡水进入海洋,与海洋里的污染物质(如腐烂的塑料制品、鱼类和海藻的排泄物等等)相互作用而形成,此外,该地区正处在强气流的影响下,在海面上形成巨大的海浪,水流使泡沫迅速向上旋转,并在岸上聚集起来,浪越大泡沫就越多,对人体没有特别大的危害。
得知了专家的结论,我们悬着的心才算放下来,但心里还是有隐隐的担忧,现在海洋的生态形势不容乐观,原因很简单,就是那些不自觉的人无休无止的破坏,几乎每天都有报道,那个工厂又污染了那条河水,赤潮年年如期而至。海洋变得混浊不堪,甚至是海里充满了有毒物质。这是当今海洋环保工作最严重、最紧迫的问题之一,真希望大家都来自觉的保卫海洋,保卫我们蓝色的国土!

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.
