海洋蕴藏着丰富的资源，是人类和所有地球生命的摇篮，也是为人类未来生存和发展提供庇护的蓝色伊甸园。远古时期，我们的祖先已经住在了海边，在大海上张网捕鱼；600多年前，中国人驾着大船驶向海洋，追波逐浪；可是今天，由于过度捕捞，向大海排放污水，以及沙滩污染物，造成海洋污染急速增加，使我们的海洋环境遭到严重破坏。近五十年来，世界海洋的污染使成千种海洋生物消亡于无形。而随着对海洋无节制开发使用，这个过程越来越剧烈，海洋环境污染与生态破坏，已经对人类的社会经济发展和人们的正常生活构成了威胁。这种势头如果得不到遏制，会给人类带来严重的后果。有人指出污染严重的渤海，可能在十年后变成死海，而如果海洋死亡，人类和一切生命也就不复存在……

要解决日益严峻的环境问题，除依靠政府的努力之外，公众的自觉行动至关重要。牢固树立公众的环境保护新思想、新道德、新风尚，是保护我们美好家园的希望所在。今天作为一个公民，爱护环境，崇尚文明，无疑更是一份必须的责任。

21世纪我们有必要选择一种更健康、环保的生活方式。为此，我们呼吁大家参与“保护海洋，从我做起”行动，树立保护环境的意识，养成健康、文明的消费方式，改变传统的行为方式和价值观念；培养自觉保护环境的道德情操，形成“保护环境，人人有责”的良好社会风尚。

为此，我们提出以下海洋环保的几条倡议：

1、大力宣传和普及海洋环境保护知识，提高国民海洋意识，要向朋友、同学、儿童和周围的人广泛宣传节约环保知识，形成大家共同参“关心大海、爱护大海”的良好风气。

2、为了保护海洋环境及资源，不向海洋及沙滩丢弃垃圾，防止污染损害，保护生态平衡。

3、减少海滩餐饮业和水产养殖的污染，使用无磷洗衣粉，不要将未经处理的.污水随意排放到河流、湖泊、海洋中。

4、不损害海洋生态资源，不捕捞受保护的海洋生物，不购买珊瑚、海龟等法律规章禁止的海洋生物制品，保护海洋生物多样性，保护海洋生态环境。

5、以“关爱海洋—我们一起行动”为，树立关心海洋、了解海洋、热爱海洋的意识，争取未来投身海洋事业。

作为热爱大海的青少年，我们更有义务担当起保护海洋的重任，成为大海的“保护者”，只有这样，大海才会更美，为了这份美丽，让我们永远地承担起保护她的责任。

海洋环境，是人类赖以生存的必要条件，保护海洋环境就是保护我们自己。人类只有一片蔚蓝色的海洋，心动不如行动，让我们携手努力把保护大海付诸行动，让全社会都动员起来，共同关心、支持海洋环境保护工作，一起做一些力所能及的保护海洋环境的事情，共同保护好、建设好美化我们的家园。通过我们自己的努力，使海洋永久美丽、家园永久安宁。

大家好!

海洋约占地球总面积的三分之二。海洋里有各种各样的生物，还有其他丰富的资源。我们生活在海岛上，大海为岛上渔民增加了很多经济收入，为岛民带来了很多方便和乐趣。同时还吸引了外地很多旅游观光者，到岛上旅游、探秘。特别是“南澳一号”的发现、考古，引起了海内外，乃至全世界的关注。作为岛民，我们感到无限骄傲。

但近几十年来，人类对海洋的污染无所顾忌，随便向海洋里倒入污染物、有害物质等，使一些海洋生物濒临灭绝，大量开采海底下的资源，使得海里很多珍贵鱼种大批量死亡，甚至有的已经灭绝。

记得我才四五岁的时候，每逢炎炎夏日，我经常和爸爸一起去大海里游泳。但在前年的时候，不知道那些没公德心的人，竟把一些日常垃圾堆在沙滩边。经海浪一冲，垃圾自然也到海里去了。看见海面上漂浮着令人作呕的垃圾。我和爸爸想游泳的心思也没了，只能叹口气摇摇头回家了。

随着人口不断增长，人们大量捕捉鱼儿，使得鱼儿越来越少，鱼儿供应不足，价钱越来越贵，人们纷纷叫苦吃鱼难。直到国家发布了禁海的条令，每年定时禁海，还定时组织相关单位的人员到大海里放养鱼苗，鱼儿的数量才慢慢多了起来。一些濒临灭绝的鱼种得到较好的繁殖，这才叫人们松了一口气。

水是生命之源。大海占整个地球的面积如此之大，她还为人们带来了那么多的益处。大家应该携手一起来保护海洋，保护海洋就是保护地球，也就是保护我们的家园。让海洋环境变得更加瑰丽，让海洋更好造福于我们的子孙后代吧!

谢谢大家!

书的海洋演讲稿篇3

pollution in the ocean is a major problem that is affecting the ocean and the rest of the earth, too. pollution in the ocean directly affects ocean organisms and indirectly affects human health and resources. oil spills, toxic wastes, and dumping of other harmful materials are all major sources of pollution in the ocean. people should learn more about these because if people know more about pollution in the ocean, then they will know more about how to stop pollution.

what are toxic wastes?

toxic wastes are poisonous materials that are being dumped into the ocean. they harm many plants and animals in the ocean and have a huge impact on our health. toxic waste is the most harmful form of pollution to sea life and humans. when toxic waste harms an organism, it can quickly be passed along the food chain and may eventually end up being our seafood. in the food chain, one toxic organism gets eaten by another, larger animal, which gets eaten by another animal, and can end up being our seafood. toxic waste gets into seas and oceans by the leaking of landfills, dumps, mines, and farms. farm chemicals and heavy metals from factories can have a very harmful effect on marine life and humans.

many fishermen believe that the toxic chemicals in the ocean are killing much of the fish population. one of the most harmful chemicals in the ocean is lead. lead can cause many health problems. it can damage the brain, kidneys, and reproductive system. lead can also cause birth defects for people. it has been shown to cause low iq scores, slow growth, and hearing problems for small children. house and car paint and manufacturing lead batteries, fishing lures, certain parts of bullets, some ceramic ware, water pipes, and fixtures all give off lead.

many things found in the ocean may cause seafood to be dangerous to human health. the effect on humans from contaminated seafood may include birth defects and nervous system damage. medical waste found in the ocean is being tested to see if swimmers have a chance of developing hepatitis or aids. other waste has been known to cause viral and bacterial diseases. this type of pollution can be stopped by watching what pollution we are letting into the ocean. people are trying to decrease the amount of waste in the oceans by recycling as much garbage as they can so there is a smaller amount of very harmful materials in the ocean.

boating pollution prevention tips

whenever someone takes their boat onto the water for a ride, it is creating pollution that can be very harmful to the sea life. boating pollution is the pollution that comes from the boatsquo;s engine when it is running, and it pollutes the water, killing animals with the chemicals in the exhaust from the engine. the engine gives off excess gasoline, which pollutes the waters and ends up killing the animals. in order to make as little pollution as possible, what everyone can do to help is:

only turn a boat engine on all the way when you need to.

donsquo;t take your boat out into the water if you donsquo;t need to.

be sure to store and transport gasoline in places where there isnsquo;t any direct sunlight because the gasoline will evaporate, and all of the gases that have been evaporated will pollute the air.

every year, buy new or cleaner marine engines for your boats.

garbage dumping

garbage dumping is the dumping of harmful materials into the ocean like human waste, ground-up garbage, water from bathing, and plastics. most of the waste that has been dumped into the ocean in the early 1990squo;s is still there today. one main cause of garbage dumping occurs when sewage pipes share their space with storm water drains. rainfall causes the sewage pipes to overflow and the sewage waste mixes with the storm water drain, which flows into another water source such as a lake or river. after that, the garbage pollutes the ocean, kills plants and animals in the water (for example, the plastic rings that are around pop cans can get around an animalsquo;s neck, causing it to suffocate), and makes the water dirty.

亲爱的老师、学生们：

大家好！

我今天演讲的是：保护海洋环境，大家共同参与。

人类只有一个地球，它是生命的摇篮，是人类共同的家园。在我们的地球上，有广阔的海洋。

有人称海洋为＂蓝色宝库＂，因为海洋蕴藏着丰富的资源，是人类和整个地球生命的摇篮，也是为人类未来生存和发展提供栖身之所的蓝色家园。

海洋中蕴藏着丰富的油气资源，人们在海面上建立起高高的钻井平台，不断地将石油和天然气从海底输送到陆地。

海洋里有无数的鱼、虾和蟹贝类，自古以来，生活在海边和岛屿上的人们一直靠海洋为生。每一个捕鱼季节，渔船总是会满载而归。海洋真不愧是一座＂蓝色宝库＂。

然而，人们把大量的垃圾倒入水中，排放废水，使海洋的危害日益增加，海洋不断受到污染，人们不知道这对海洋有多大的危害。鱼，有些翻着白肚皮，其它在海里的`动物，也遭到了厄运。

总有一天，海洋会变成一个臭气熏天的垃圾场。此外，还有很多鱼、虾、螃蟹、贝类散发出腥臭味，在那之前，人类就会明白自己做错了什么。

人们还把海洋中的所有资源运输到陆地上。虽然海洋中有很多资源，但如果每天不断地将海洋中的资源送到陆地上。

慢慢地，海洋就会逐渐变小，有一天，人们又来取了，但大海早就变成了一个湖泊。人们就开始认识到自己的错误了。

海洋中有许多生物，其中有超过16万种。它们生活在不同的海水深处，一条＂生物链＂将它们连接在一起；有些鱼和虾吃藻类或蜉蝣生物，有些大鱼专门吃小鱼。海洋生物是宝贵的渔业资源，每天为人类提供丰富的鱼、虾和各种海鲜。

人类在海洋中捕杀大量的生物，有些吃掉，而另一些人则利用自己的条件将它们加工成日常必需品。海洋中的生物逐渐减少，虽然它们也繁殖后代。

但人类将各种废物倾倒到海里，造成严重的海洋污染，使海洋中的生物难以生存，大量死亡，最终都会死亡！

future marine

know you today from the 2009, let me do a return tour, you tour in 2030 with the "ocean", i think you must be harvested. as we all know, oceans of the earth's seven tenths, very serious marine pollution in 2009, but in 2030, due to advanced science and technology, "decontamination robot" has become the bane of marine pollution, so, when there is no pollution in the ocean. now, i take you first "multi-functional reception", and replace "changes in the marine location device", it all took us off to another world. today's oceans, is home to human beings, 50 percent of people worldwide live in the ocean, you will find it very curious about how to survive in the ocean? fact well, sea world, where there is an "oxygen control room," oxygen produced from here, through the "oxygen cylinder" sent to every corner of ocean, people breathing in fresh oxygen, emit carbon dioxide, and then by the "oxygen control room" to receive, but also to create such a cycle of oxygen ... ....

harbour fish is strange, since the sea water into fresh water, the fish learned human language, but also to talk with people it can be fun! you to the front of a large group of fish, fish said: "good morning!" fish will speak english, i am really not believe it. listen to my introduction to you on the residential areas. although before you see is a blank, but people live here. the sea and land were not the same person, they food is simple, a "simple food dan" can be over 100 days, so they are very relaxed. live it? to four "sea" as their home, think of where to sleep on where to sleep, carefree.

then, you visit the royal palace, park ... ... must have felt very grand, magnificent it! perhaps you worry about, so many people living in the seabed, the environment will not occur the problem? not. harbour achieved without factory, but there are production. and no worse than the production of the land, because we row down the waste land, water, through the "decontamination robot" "pass" "make the robot" for processing, making available all kinds of things ... ... strange, wonderful sea world tour finished, how? i am sure you will feel the power of science is so magical.

敬爱的老师，亲爱的同学们：

大家好!

那无边无尽的汪洋大海是曾今所养育我们的摇篮，大海是地球的母亲，是生命的起源。里面有取之不尽用之不完的石油，为人类提供了宝贵的资源。为人类体供鲜美无比的海鲜……

海里有珊瑚礁，有鲨鱼群，有企鹅，有世界上最大的动物—蓝鲸。以前海洋是湛蓝湛蓝的。可现在海洋不在蓝了开始变黑了，开始变浑浊了。大海妈妈开始生气了，它渐渐的感到后悔，她亲手造就了一班来决定让它变得越来越黑，越来越浑浊的人类。使至今在它怀抱里的宝宝一个个离她远去。比如蓝鲸，根据资料的显示，近年来不知道多少蓝鲸遭受人类的戳杀。为什么呢?就因为人类的贪婪金钱的欲望，人类的残暴。让无辜的蓝鲸遭受如此巨大危险。

捕鱼是可以进行的，人需要营养所以大海妈妈将自己的乳汁给了我们。它那些充满着营养的乳汁开始传到世界各地，每天都可以看见新鲜的鱼从港口运来。大海妈妈看到自己的孩子得到了营养心里欣慰，但人类却恩将仇报，使海洋受到污染，使海洋里的生物难以生存。

现在的.人为了金钱甚至会不惜代价。一些捕鱼的人开始滥捕，许多鱼在市场卖不出去。便被人们扔进了垃圾桶。此时，大海妈妈在那里不停的哭泣。而人类却一点也没体会到大海妈妈的伤心，不会设身处地的为大妈妈着想。

现在地球环境越来越差，人们开始不段排放有毒污水，让海里的鱼逐渐面临死亡。这种鱼一但被人类吃了，后果不堪设想。真是聪明反被聪明误，自食其果。

垃圾越来越多，似乎人类把大海妈妈当作了世界上最大的垃圾桶。越来越多的垃圾沉积在海底，使大海妈妈越来越脏越来越黑。大海妈妈能不再一次伤心吗?

在钱塘江每年都有壮观的潮水，使得世界各地的人前来观看。可近年来似乎跟以往有所不同变得严重了，那可能是大海妈妈对人类的所作所为感到伤心。开始落下一滴又一滴的眼泪。

大海妈妈的伤心和生气原自哪里呢?原自人类，只要人人做好环境保护让更多的垃圾进垃圾它自己的家—垃圾桶。不要为了金钱损人利己，让大海妈妈再一次展现它柔美、发自内心的微笑吧!让大海妈妈觉得人类值得让大海妈妈骄傲。让大海妈妈觉得人类在好好的孝顺它。人类是爱它的。
