沧海横流，方显出英雄本色！建设一个强大的海洋中国是我们每个人的神圣使命。中国人的发展观、中国人的'强国梦从未间断。暴风雪可以阻断归程，但扑不灭强国的热情；地震可以翻覆天地，但震不垮民族的精神。中华民族遇强则强，越挫越勇。我们，新时代的青少年，我们的青春需要用知识来挥洒，我们的大脑需要用科技来武装，我们的双手需要用力量来舞动。我们的祖国、我们的民族需要我们成为栋梁。我们无权沉默，因为我们知道未来就在我们身边，就在我们手中。我们可以这样扪心自问：1840年，我们的国家没有火轮船，那么，21世纪的我们能不能给自己的国家提供领先于世界的xx？

祖国期待着我们的回答，更期待着我们的行动。我们没有理由不努力，不脚踏实地、不勇敢的承担起支撑共和国大厦的责任。我们，不仅要在960万平方公里的国土上播种未来，更要在300多万平方公里的海疆上收获希望。祖国，今天，我们为您而骄傲；明天，您一定因我们而荣光。

现在，地球陆地上的资源日益开始枯竭，海洋成了人类持续发展的最后空间。渤海、黄海、东海和南海，这蓝色的土地下，资源丰富，开发潜力巨大。其中，海洋生物2万多种，海洋鱼类3000多种；海洋石油资源量约240亿吨，天然气量14万亿立方米。可以说，海洋就是一个巨大的宝库，这个宝库的大门，正在向我们徐徐敞开。而日本、越南、菲律宾、印度尼西亚等几个小国，为了扩大自己的海域，竟把魔爪探向了中国！伸向了我们宝贵的海域！面对这些周边国家的无礼要求和无耻行径，我们怎能不愤慨？追溯历史，我国在西汉时期就已经把南海纳入自己的国土。对此，我们有充分的历史和法律依据，南海是我们的，中国的海域是不容侵犯的！

少年智则国智，少年强则国强，作为新世纪的少年，让我们走向海洋，保护海洋，保护我国的蓝色领土！

海洋演讲稿篇2

尊敬的老师，同学们：

大家上午好

小时候的我，住在小山城里，从没见过海，那时候经常听周围的人提起海，听他们在旅游时候怎么在沙滩上玩耍，怎么在海边游泳嬉戏，再加上电视里播放的各种海的美景，一颗期待着能亲眼看见海洋的心的种子便开始悄悄发芽了。

16岁的我，终于有机会能走出山城去看海了，那时候，当车窗里的一角开始出现海洋的轮廓的时候，我的内心开始翻腾，从初见的惊喜瞬间变成了意外的失望，是的，是失望。为什么会失望——因为海没有它本该有的模样，它的颜色，不是电视里那灿烂的碧蓝，深邃的深蓝，而是死气沉沉的灰蓝;它的边缘，铺满了人类留下的垃圾，和肚皮朝上的死鱼。

我很想知道，是什么让它变成了这副模样?

海洋，孕育了地球的生命，也蕴藏了丰厚的资源。地球71%都是海洋，至今仍有80%的动植物生活在海洋中，可见，海洋对于我们来说，是多么的重要。

但是，很多人认为，海洋就像是我们日常生活里的一部分，是街边的马路，是聚会结束的不需要收拾的会场;小小的塑料袋，扔在海边好像没有什么太大关系，工厂里的废水，排到海里也似乎不会有什么问题，人们的小小举动，就在这么看似不短的时间里，为海洋留下了难以恢复的伤疤。

当然，也有很多人认为，海洋里的资源那么丰富，取之不尽，用之不竭，我们为何要担心鱼群的灭绝和资源的用尽呢?我们曾经认为的吃也吃不完的蓝旗金枪鱼，由于人类对美食的追求和对利益的贪婪，已经在濒危物种列表上榜上有名了，最为人们广泛流传的，还是央视的拒绝吃鱼翅的广告，无辜的鲨鱼，活生生地被人类抓捕，被肆意地割下它们的双翅，然后绝望地沉落在寂静的海里，它们也不知道自己做错了什么，自己的鲜血还引来了同伴的杀生。

而我们，又能为它们做些什么?

怀着这份好奇，我意识到，海洋保护已经刻不容缓。

我们的生活，离不开水，跟离不开海洋，如果我们没有水，或者说如果我们没有干净的水，那么我们的生活又会是怎样子的——百姓对政府怨声载道，原本可以作为平时观赏的海现在已经难以入眼，原本以海洋为经济支撑的产业也开始经济萧条;那或者说如果金枪鱼消失了，中华鲟鱼和鲨鱼也消失了，我们又会有怎样的担忧，怎样的悲痛?

有些人，他们深深爱着海洋，他们是海的儿女;有些人，他们深深敬畏着海洋，被海洋无穷的力量征服。海洋的魅力，我们都能目睹，如果你亲眼看见美丽的海洋，就不会想让她受到伤害，就像是自己曾经去过的让自己流连忘返的美景，如果它哪一天变得不再漂亮，已经没有了自己的本色，那么此时的自己，又会是怎样的心情呢?

我真诚的希望，海洋的保护能得到大家的足够重视，希望真的有那么一天，海还是以前的那个美丽的海，海里的生物还是像以前那样自由自在不用担心自己的种群是否会在地球上消失，那时候人与海洋和谐共处，那时候海洋与我们同在。

谢谢大家!

大家好!

海洋，占了全球百分之七十一的面积，我们对它再熟悉不过了。可是，目前海洋在被不停地吞噬着。我们要下决心保护海洋，希望在这不久的将来能实现。海洋对于人类是十分重要的。它有着十六余万种的海洋生物。极为丰富的天然气和石油。几千种陆地上微乎其乎的微量元素、矿物，几百种陆地上稀有的金属。海洋每年为人类提供三十亿吨的鱼。在四万一千立方米的水中，有着两百亿吨的盐。

然而，可悲的是这样对人类有益的海洋，人类在享受的同时却肆意的去破坏它!人类将生活垃圾、废水成批成批的倒入海洋中，放肆地采摘海洋中的植物，使大海以每秒一平方米的下降趋势慢慢减少。鱼、虾、蟹、贝等慢慢减少，海水开始变得浑浊、肮脏，甚至发臭。总有一天，大海会变成一个大垃圾场，臭味逼人。大海的脾气随着人类的破坏程度，也发生了改变。原本心平气和的大海开始变得狂躁不安。

随着人类的破坏，海洋多次发生海啸，漩涡和风暴潮。就拿20__年印尼的海啸来说吧。愤怒的大海就像脱了缰的野马，狂暴的野兽，刹那间形成了数十米高的水墙，珍贵的生命、高大的楼房，坚硬的汽车等等，都被海水吞噬掉了。想想它的破坏程度，造成的损失，多少的家离子散。

大家是否记忆犹新呢?但是，竟然有些厚颜无耻的人还说是天意。让我们所有的人都行动起来吧!保护我们可爱的海洋!

谢谢大家!

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.

海洋演讲稿篇5

the simplest water pollution definition would be any contamination of water bodies with some pollutant(s) that changes physical,biological,and chemical conditions of any body of water making this water harmful for environment and surrounding ecosystems.

water pollution occurs once too much pollutants (mostly in form of different waste) are discharged directly or indirectly into water bodies.water pollution does not only cause great environmental damage but is also the leading worldwide cause of deaths and diseases responsible for the deaths of more than 14,000 people each day,mostly in developing countries.

many people are not aware that water pollution is serious problem in almost all parts of the world,and not just in third world countries like some choose to believe.in fact many experts will tell you that reality is completely different than the common belief,and that actually water pollution problem is already out of control.

water pollution problem is in most cases connected with the careless handling of chemical agents,toxins introduced into our water through industrial dumping,and farm runoff.all these factors make our water unsafe to drink.

for instance,the chlorine that is widely used to disinfect our water is believed by many to be carcinogenic,and therefore a major health issue that significantly contributed to worldwide rise of cancer rates.

basically chlorine is present in every glass of water we draw from our tap,and although some studies have confirmed that chlorine can indeed be one of the cancer risk factors we simply cannot do without it because by removing chlorine from our water we would open the door to many waterborne diseases that would kill millions of people around the globe.

so how to protect yourself from water pollution?the best option available to us is to install a multi-layered home water filtering system in your home.the best option is multi media block system that has an activated granular carbon filter,a sub micron filter,and an ion exchange.this system is capable to prevent up to 99.99% of all of the harmful contaminants present in our water from entering your home.

high quality home water filtering system is really your best ally against water pollution.
