海洋污染作文1
河流、海洋、湖泊、水潭的污染越來越大。
人們亂扔垃圾入江河、湖海，原來美麗的河流瞬間變成了一條臭水溝，多少水生物死于我們亂扔垃圾的行為�。�
還有，我們建立這么多工廠，本來是對環(huán)境影響不大，可是，那些工廠卻把不達標的污水、垃圾、鉛、毒…倒入河流和海洋。
一些海洋生物吃了這些垃圾之后造成死亡，如：海魚，一旦吃了垃圾身體就會飄浮在水面上身亡。
我們這是自己走向滅絕，因為我們未來會很發(fā)達，樓房會占領(lǐng)了森林和田地，那些能讓我們食用的海洋生物也被我們逼它們走向絕境，也是在逼我們走向絕境。我們不應(yīng)該亂扔垃圾和排放化學(xué)物質(zhì)入江河，海洋等水地。
我下定決心要在假期和休息日時把水里的垃圾清理干凈，堅持環(huán)保并向人們宣傳環(huán)保意識，讓我們的生存環(huán)境可持續(xù)健康發(fā)展。為了我們的家園更美麗，請大家關(guān)注海洋污染，行動起來，保護我們的母親河！
海洋污染作文2
從小老師就教育我們，大海孕育了我們的生命，每一個地球人都應(yīng)為保護海洋環(huán)境貢獻自己的力量。
眾所周知，海洋對我們每個人都很重要。它占據(jù)地球表面積的71%，遠遠的從太空看，地球就像一顆晶瑩剔透的藍色水晶球，這就是地球又被人們稱為“水球”的原因。因而破壞海洋的行為會對整個地球造成影響。
放假的時候我最喜歡到海邊玩啦，光者腳丫子在海灘上跑，很快海水就會漫上來，蓋住一串串腳印，跑累了就看看大海，站在高高的礁石上眺望遠方的海平線，海水藍藍的.調(diào)皮的拍打著海岸，勇敢的海鳥在海浪中穿梭，多希望這一刻永遠印在腦海中!
可是最近污染海洋的新聞越來越多，每當看到這些新聞，我就為海洋擔心，為人類的自私感到羞愧，為人類盲目追求經(jīng)濟增長造成海洋污染的后果感到憤怒。我越來越擔心大海里的小生命會受到傷害，擔心海鳥失去生存的家園，擔心總有一天人類會受到大自然的報復(fù)。
海洋無私的幫助我們，我們卻反過來破壞它，這不是老師教我們以怨報德的故事嗎?所以我們不能忘了大海的貢獻，我們應(yīng)當愛護它，把它當母親一樣關(guān)心、呵護。當我們傷害了它，我們應(yīng)當感到內(nèi)疚，應(yīng)當做出更多補償。
小學(xué)生人小力量不小，我們可以從點滴小事做起，比如說把平時的零用錢攢起來捐給愛護海洋基金，可以在放假時去海邊撿撿垃圾，可以向身邊的人宣傳保護海洋的知識……讓我們行動起來，為保護海洋奉獻自己的力量吧!
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.
海洋污染作文4
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，我們的海洋是那樣的美麗，波光粼粼，令人心曠神怡，流連忘返。但現(xiàn)在呢！這些海洋已遭受嚴重污染，無論是亞龍灣，還是瀏陽河，都可以看到成堆的垃圾，散發(fā)出難聞的味道。
那這又是因為什么造成的呢？這都只能怪我們自己。(.)它們主要是從油船與油井出來的原油，農(nóng)田用的殺蟲劑和化肥。工廠排出的污水，礦產(chǎn)流出的酸性溶液，它們使得大部分的海洋，湖泊受到污染，結(jié)果不但生物不能生長，就是鳥類和人類也可能因吃了這些生物而中毒死亡。這是一個難以置信但千真萬確的數(shù)字，每24小時便有2.5萬人（包括兒童）死亡于吃了被污染的海水里的魚蝦。還不僅僅這樣，中國工程院院長，湖泊環(huán)境研究主席，科學(xué)家劉鴻量教授對全國
5500千米河段進行研究調(diào)查，報告顯示，百分之二十三點三的河水段水質(zhì)污染嚴重而不能用于灌溉，百分之四十五的河段里魚蝦絕跡，百分之八十五的河段不符合人類飲水用水標準量，而且河流自潔等生態(tài)功能也嚴重衰退，形勢異常嚴峻。當我們的宇航員飛上太空，目睹我們的地球，映入眼簾的是一個晶瑩的球體，上面藍色和白色的紋痕相互交錯。但是如果我們再這樣讓海水受到污染，那么藍色會漸漸消失，地球?qū)⒆兊靡黄祝?/p>
為了我們有一個美好明天，為了我們的子孫后代能夠更好的生活，讓我們共同努力吧！
海洋污染作文6
我是一名海上環(huán)保小組的成員，保護海洋環(huán)境，定期對海上生態(tài)情況進行檢查是我的任務(wù)。
一天早上，我和兩名小組成員向往常一樣坐上巡檢船去海上巡查，當我們的船航行到澳大利亞新南威爾州的亞姆巴海岸線時，海水檢驗系統(tǒng)突然發(fā)出“嘟嘟嘟�！钡膱缶�，我趕快調(diào)出電腦監(jiān)控圖像查看，一看屏幕我被嚇了一跳，平時藍藍的大海不見了，一層層白色的泡沫堆積在海面上，隨著波浪一起一伏，好像巨大浴缸中的泡泡浴。
渾濁帶著泡沫的海水沖向海灘，沖打著岸邊的度假者，人們驚慌的四散而逃。出事了?那白色的是什么東西?為什么會這樣?會不會有危險?一連串的問題出現(xiàn)在我的腦海里。我馬上把險情報告上級，上級指示我們搞清情況。
為了搞清原因我們決定親手取一些泡沫作樣本，走進變成“卡布奇諾咖啡”一般的大海，我和組員都捏著一把汗，不知這種不明物質(zhì)對人體有多大危害。我們穿上藍色的潛水服，戴上長長的塑膠手套和防護境，手里拿著兩個實驗玻璃瓶，潛到海下，我發(fā)現(xiàn)海面下的海水還是深藍色的，比平時的海水渾濁許多，白色的泡沫只浮于海水表面，沒有什么刺激的味道。我們很快取到樣本，隨后向總部發(fā)出信號，等待專家的到來。
經(jīng)過專家一番仔細檢驗，發(fā)現(xiàn)這種不明的白色泡沫，是由于大量從河里流出的淡水進入海洋，與海洋里的污染物質(zhì)(如腐爛的塑料制品、魚類和海藻的排泄物等等)相互作用而形成，此外，該地區(qū)正處在強氣流的影響下，在海面上形成巨大的海浪，水流使泡沫迅速向上旋轉(zhuǎn)，并在岸上聚集起來，浪越大泡沫就越多，對人體沒有特別大的危害。
得知了專家的結(jié)論，我們懸著的心才算放下來，但心里還是有隱隱的擔憂，現(xiàn)在海洋的生態(tài)形勢不容樂觀，原因很簡單，就是那些不自覺的人無休無止的破壞，幾乎每天都有報道，那個工廠又污染了那條河水，赤潮年年如期而至。海洋變得混濁不堪，甚至是海里充滿了有毒物質(zhì)。這是當今海洋環(huán)保工作最嚴重、最緊迫的問題之一，真希望大家都來自覺的保衛(wèi)海洋，保衛(wèi)我們藍色的國土!

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.
