可以为我写一篇,高中生关于海洋生物的英语演讲稿吗

海马 Seahorses Seahorses are a species of fish belonging to the fish family Syngnathidae, which also includes pipefish. The pipefish and seahorse are found in tropical waters all over the Caribean. Seahorses range in size from 16 mm (the recently discovered Hippocampus denise[2]) to 35 cm. Seahorses and pipefishes are notable for being the only species in which males become pregnant.[3] It has a dorsal fin located on the lower body and pectoral fins located on the head near their gills. Some species of seahorse are partly transparent and are rarely seen in pictures. Sea dragons are close relatives of seahorses but have bigger bodies and leaf-like appendages which enable them to hide among floating seaweed or kelp beds. Seahorses and sea dragons feed on larval fishes and amphipods, such as small shrimp-like crustaceans called mysids (sea lice), sucking up their prey with their small mouths. Many of these amphipods feed on red algae that thrives in the shade of the kelp forests where the sea dragons live. Seahorses reproduce in an unusual way: the male becomes pregnant. As stated on The Seahorse Project, The female inserts her ovipositor into the male’s brood pouch, where she deposits her eggs, which the male fertilizes. The fertilized eggs then embed in the pouch wall and become enveloped with tissues. New research indicates the male releases sperm into the surrounding sea water during fertilization, and not directly into the pouch as was previously thought.[4] Most seahorse species' pregnancies lasts approximately two to three weeks. Hatched offspring are independent of their parents. Some spend time developing among the ocean plankton. At times, the male seahorse may try to consume some of the previously released offspring. Other species (H. zosterae) immediately begin life as sea-floor inhabitants (benthos). Seahorses are generally monogamous, though several species (H. abdominalis among them) are highly gregarious. In monogamous pairs, the male and female will greet one another with courtship displays in the morning and sometimes in the evening to reinforce their pair bond. They spend the rest of the day separate from each other hunting for food.

保护海洋动物演讲稿

一场特殊的宣判 在地球刚刚形成时,最先见到是那蔚蓝的大海,生命在此繁殖,不停的演变。

一切都那么井然有序。

成群结队的鱼,五彩斑斓的珊瑚,一切都是那么的美好,鱼儿快乐的游就像一个个跳动的音符。

大海就是无与伦比的五线谱。

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。

关于海洋污染的英语演讲稿~

急急急急~

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 TipsWhenever 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 boat’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. Don’t take your boat out into the water if you don’t need to. Be sure to store and transport gasoline in places where there isn’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 DumpingGarbage 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 1990’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 animal’s neck, causing it to suffocate), and makes the water dirty.

拯救海洋的青年500字演讲稿

看着鸟儿在天空,看着鱼儿在水中遨游.也许你为世界上的动多吧!但你知道,现在的动物不仅不多,而且有的动物已经很稀少,甚至某些动物已经灭绝.根据生物学家估计,几千年来被人类捕杀以致绝种的动物至少有数百种以上.如此一来,那世界上的动物种类越来越少,如果我们不能够及时挽救的话,那么将来世界上的动物就只有我们人类自己了!你别以为我是“危言耸听”,你若不信,我可以告诉你.   就拿印度洋毛里求斯群岛上生活的渡渡鸟来说,由于它身上的肉鲜美无比,所以遭到当时人类的大量捕食,在十七世纪就已告灭绝.但是如果当时人们有动物保护意识的话,就不会造成渡渡鸟的灭绝.再说生活在我国青藏高原的藏羚羊吧,因为它其外层皮毛下面的被称作沙图什的绒毛异常精细,可以用来织成华丽的披肩,而惨遭偷猎者大肆捕杀.因为织出一条女式沙图什披肩便需要300至400克生绒,这意味着要牺牲3只藏羚羊的生命.所以在上世纪90年代初期,藏羚羊的数目只有65000只到72500只之间,要知道这只有100年前藏羚羊总数的十分之一.所幸的是人们意识到了保护这种濒临灭绝的动物.现在北京已有多名志愿者来到可可西里担当起义务看护藏羚羊的活动.同时国际爱护动物基金会从1999年起每年为我国藏羚羊保护捐赠8万至10万美金用以在可可西里、羌塘和阿尔金山三大自然保护区开展反盗猎行动和针对藏羚羊保护的各种宣传活动.我们人类正慢慢将藏羚羊这种可爱的动物从灭绝的边缘拉回来.   朋友们,动物是大自然留给人类的无价之宝,它是我们人类的朋友.它们的生衍死灭与我们人类的生活是密切相关的.动物的大量毁灭对人类将产生严重的不良后果,造成生态严重不平衡,从而使人类的生存环境遭到破坏.让我们从现在做起,从我做起,保护动物,使世界变得更美好吧!   贪欲消灭人类   程啸   白鳍豚原是长江的龙头老大,居于长江水生生物食物链的顶端长达2500万年,在漫长的水域里所向披靡,但是它们最终灭绝了.上世纪80年代初种群数量为400头左右;1986年,300头;1990年,200头;1994年,100头以下;1997年,13头;1999年,5头;2006年,生命之旗已经降落.这位长江的原始主人无声无息地消失了,在一个不为人知的时刻,完成了最后的挣扎,把最后一滴眼泪汇入了奔腾不息的万古长江.这可怕的灾难只有可能来自——人类.   上帝派了个天才来向人类透露它的绝密消息,那个叫做霍金的天才歪歪斜斜地坐在轮椅上,口齿不清地说:最后的日子,就在下个世纪.   霍金说的很对,人类末日不再遥远.   是什么导致人类的灭绝呢?   是欲望!是的,人类贪婪的欲望导致了动物的灭绝,导致了地球的变异,导致了灾难的产生,最终,贪欲将灭绝人类自己.   香格里拉人是外星人遗留在地球上的高智能物种,是他们创造了人类,并且进行了一次清除.东方佛经里所记载的乐园叫香巴拉,西方传说的乐园叫伊甸园.伊甸园中的一对男女最终被欲望驱使而犯错被驱逐出了乐园.香格里拉人制造了人类,但是人类被欲望驱使,最终繁殖过多,被香格里拉人惩罚,将人类所在的大陆沉入水底.西方人说是挪亚方舟拯救了人类,其实,那只是人类为了躲避洪灾而逃到神圣的地球最高峰——喜马拉亚山.据说进入香格里拉世界的通道在布达拉宫的底部,但是,很少有人进入.神圣的香格里拉已经抛弃了人类,这是因为,人类有贪婪的欲望,而这欲望,和传说一样,会导致人类的灭绝,而毁灭人类的工具就是——洪水.   贪婪的欲望本身就是洪水猛兽,最终,洪水猛兽将吞噬人类,吞噬人类的欲望.   你可曾发现?在局部范围,洪水越来越猛烈,不管人类科技如何进步,也无法抵抗?你可曾发现?海啸越来越猛烈,可以瞬间吞噬无数岛屿?你可曾发现?台风越来越猛烈?可以将一切都拦腰折断?你可曾发现?冬天变的如此短暂,气温升的如此快速?你可曾知道?喜马拉雅山的冰川正在融化,北极冰雪将在本世纪内消失,纽约、东京等城市将被上升的海水淹没.   还有更多你所不知道的,那深沉的海底,隐藏着太多史前的古生物,当海水逐渐上升,当城市逐渐被淹没,人类,都将成为海底猛兽的快餐.   人类的末期啊,已近在眼前.是欲望,是贪婪的欲望,最终消灭了人类自己!   地球满足不了人类的贪婪

拯救动物的英语演讲稿非常简单

Many wild animals are facing the danger of extinction, because the environment that they are living in has changed greatly. For example, with the developmet of cities, the using of insecticide and serious pollution, their living areas have become narrowcr and narrower. Many of the wild animals, now are confronted with food crisis. At the same time, man is killing off species just for getting their fur, skin, horns, teeth and meat.  In order to protect our resources of ecology, people should realize that the loss of any species is at least the loss of source of knowledge and a source of natural beauty. There fore, measures of the following should be taken: pollution standards are made to keepdown poisons; killing off certain rare species is prohibited; national parks should be set up as wild life, reserves.  Only if we human beings take some drastic measures can wild animals be preserved许多正面临绝种的危险,因为它们生活的环境发生了极大的变化。

譬如,随着城市的发展,杀虫剂的使用和严重的污染,的生活区域变得越来越狭小。

许多中、国、演、讲、网、目前正面临着食物方面的危机。

同时,为了获取野生动物的毛、皮、角、牙齿和肉,人类正在屠杀野生动物。

  为了保护,人们应当意识到任何物种的缺失,至少意味着知识资源和自然美的缺失。

因此,应采取以下措施:制订污染标准以降低有毒物质;严禁杀害某些;应建立国家公园作为保护区。

  我们只有采取一些有力措施,才能保护野生动物

不用太长。

提示如下。

5月1日上午,天气真好,碧空万里飘着朵朵白云。

我跟随着爸爸乘着公共汽车来到了玉环观光园。

经过了两个小时的跋涉,我们就来到了目的地。

一下车,一阵和旭的春风轻轻从我身上吹过,一路上的疲倦立刻灰飞烟灭,感觉万分的舒坦。

走进观光园,向右一拐,眼前是一个广场,广场上有一座石雕,雕刻的是一个牧童骑在牛背上,那牛是深黄色的,两只黑黑的眼睛盯着我们。

牧童欢快的表情栩栩如生,好象是特意来欢迎我们的。

广场后面有一个舞台,我们在那儿观看了几个有趣节目,有一个七岁的小女孩把椅子一把一把的垒起来站在上面,叠了一个又一个,有七八个椅子,我看最少3米高,而那女孩子却稳稳地站在那里;有一个演员用脚撑起一口三百多斤的大缸,后来又坐上一个大人和两个小孩,三个人大概共有五百多斤,可那口大缸还是纹丝不动。

除这以外还有现代舞、民族舞等各类舞蹈。

随即,我们来到了果园,果园里有粉红的桃花,有雪白的梨花,这里一片,那里一片,好像我们来到了花的海洋。

这里不仅有好看的景观,就连味道都是非常非常的香,好像比蜜的味道还甜许多许多。

最后,我们来到了百鸟园,百鸟园是北京唯一模拟自然环境的鸟类观赏保护中心,百鸟园中有许多种类属于我国一、二类保护动物,如褐马鸡、丹顶鹤、绿孔雀、红腹锦鸡,更有不远万里来北京的黑天鹅、澳洲鸵鸟。

这些珍奇鸟类使我大饱眼福。

时间流逝的真快,一转眼天就黑了,我和父亲依依不舍地离开了玉环观光园。
