关于保护海洋的英语小作文（实用20篇）

Environmental problems are being more and more serious all over the world。

For example， cars have made the air unhealthy for people to breathe and

poisonous gas is given off by factories。 Trees on the hills have been cut down

and waste water is being poured continuously into rivers。Furthermore， wherever

we go today， we can find rubbish carelessly disposed。 Pollution is， in fact，

threatening our existence。

The earth is our home and we have the duty to take care of it for ourselves

and for our later generations。 Fortunately， more and more people have realized

these problems。 Measures have been taken to cope with these problems by the

government。 Laws have been passed to stop pollution。 I hope the problem will be

solved in the near future and our home will bee better and better。

在一个周六，我和爸爸、妈妈到海边去游玩。远远的，我就闻到一股臭哄哄的味道；看到海水乌黑乌黑的；海中漂着各种包装袋，食品盒……海洋生物身上全是油，不久就会死去。

还记得以前，我来的时候：湛蓝清澈的海水；海鸥在天空自由的飞翔；各种海生物在海洋里快乐的生活着……

而现在为什么都变成这个样子了呢？我查阅资料，才得知有些人想省钱不建污水处理池，直接把污水排进大海，才让大海臭哄哄的；输油管道质量不合格、操作方法不当，造成石油泄漏，海面才黑乎乎的；有些人随便往海里扔垃圾，海中才会都是垃圾……

以后，我们一定要保护大海，把污水排进污水处理池；把垃圾放进垃圾桶；不在海边建大油田、化工厂；适量扑捉海洋生物……

让我们行动起来吧，让大海恢复往日的美丽吧！

以前的海边海水被污染了，小鱼死了被油污的螃蟹想爬到岸上寻找生活空间。

"Bumper harvest, bumper harvest!"!" Cried one of the fishermen, happily jumping up like a child. After a while, the full cabin fish alive and kicking, calm sea filled with coming from all sides of the fishermens laughter.........

Now, like this "fish and shrimp full cabin" scene has been very rare. In todays market, is the most common fish pound at least to dozens of yuan, more serious pollution of the ocean, the ocean resources gradually dried up, seafood production, prices rise, it illustrates this point?

In the ocean of natural calamities and man-made misfortunes emerge in an endless stream today, human pollution is often not from the original intention, but it is caused by the unexpected effect. The British Petroleum oil, because the drilling platform explosion, caused by the oil spill in the Gulf of Mexico, to 9900 square kilometers of sea water is seriously polluted, so that tens of thousands of seabirds soaked in oil to move, die in hunger and misery, makes countless fish poisoning death; and the Japanese earthquake and tsunami triggered a nuclear leak the marine pollution is more serious......

The sea is so vast that it is because the rivers and streams flow into the Yangtze River and then run into the sea. If we do not solve the pollution problem from the source, then no matter how people clean up the sea, there will always be sewage flowing into the sea, and all the efforts will be futile. Now, streams and streams are often seriously polluted, or they become places where people dump rubbish or are loaded with pesticide cans. Finding a clear stream in an inhabited area can be very difficult today!

In any case, the protection of the oceans can not be achieved by individual forces, and the protection of the oceans depends on the joint efforts of all mankind. I do not want one day in the future, our descendants can only imagine the image of the vast and wide sea.

This is not only the wish of a pupil, but also the wish of all mankind, isnt it?

The classmates, you might think a little convenience bag, no pollution, this you are wrong. A small convenience bag can also be water pollution.

In every household in baicheng almost a year in more than 100 convenience bag. If only more than 100 households in baicheng, convenient to use every year about ten thousand bags. We think about lets light has 100 households in baicheng? At school, I have to take a fruit every day. But the fruit of the outer packing is a small plastic bags which convenience bag to the environment pollution is very serious. And we generally just one-time use it. Used the bag into the junkyard. But most have been put into our nature.

I want people to use less some convenience bag to bag and reduce the white pollution, please take good care of our home, save the earth mother to live!

同学们，你们可能都认为一个小小的方便袋，没有什么污染，这你们可就错了。一个再小的方便袋也能污染水源。

在白城市每户人家差不多一年就能用100多个方便袋。白城市要是只有100多户人家，大约每年都要使用一万个方便袋。大家想想咱们白城市光有100户人家吗?在学校上课时，我每天都要随身带一种水果。可是水果的外包装是一种塑料做的小食品袋这种方便袋对环境的污染十分严重。并且我们一般只会一次性使用它。用过的袋子就进了废品收购站。但大部分却被弃入了我们的大自然当中。

我希望人们少用一些方便袋改用一些布袋，减少一些白色污染，请大家爱护我们的家园，救救生存的地球母亲吧!

[保护环境为题目的英语作文

谁都知道我国有960万平方千米的土地，但又有谁知道，隶属我国的海洋面积有多少呢?还是让我来告诉你吧!是300万平方千米。

有人可能会问：既然有这么广阔的土地，那海洋生物也应该很多才对吧!没错，我过的海洋生物数量占世界的10%左右。这些海洋生物就像我们的兄弟姐妹一样。但我们的兄弟姐妹正在慢慢的消失，为什么?因为我们人类。

大家应该知道白鳍豚吧!它是全世界那么多国家，唯独中国才有的稀有动物，生活在长江中下游，由于我们人类所建的化工厂所排出来的废水对长江的水质早成了污染，还有生活垃圾......这些无情垃圾破坏了它们的栖息地，使它们无家可归，适应不了被污染得十分严重的环境，最终，这种国家一级保护动物，这种古老而美丽的动物，有"活化石"之称的白鳍豚的数量不及大熊猫的5%。

藏羚羊是国家一级保护野生动物，全世界99%的藏羚羊生活在我国西部海拔4500米以上的高原上。藏羚绒又轻又软，保暖性强。用它制成的披肩在20世纪90年代成为了西方富人的衣着时尚。然而想要采集这种绒就必须得把藏羚羊杀死。目前，存活的藏羚羊仅有15000--100000只，为100年前十分之一。如果继续残害它们，不采取任何保护措施，20年内藏羚羊将灭绝。

这两种动物虽然不是海洋生物，但我认为如果我们继续破坏环境，捕杀动物的话，海洋生物也会面临生命危机的。比如：海洋生物当中最大、最重的蓝鲸，由于人们的随意捕杀，和人们对环境的毁坏，蓝鲸数量正在急剧减少。

As time goes by, man is making the earth sick. People cut down too many trees and leave rubbish everywhere. Factories let out their waste without doing anything to it . This has caused some serious problems. Such as the land is sandy, the river is dirty, the air is less clean, even the temperature of the earth is rising. What should we do to save the earth ? My suggestion is that we should plant more trees, put rubbish into dusbins and stop factories (from)pouring waste directly into the air or rivers. In all, we have only one earth, we should do our best to protect it, or we will regret.

The national level protection animal giant panda, have you ever seen giant pandas? Come and see! The following is a lovely giant panda, see how delicious it eats! The smile is so lovely.

You said, why so little panda, it is because of the destruction of the human disorderly cut down trees, dont take care of flowers and plants, destruction of the atmosphere, to lead to a drop in the panda, so we have to take care of the panda, the giant panda is herbivorous animals know, likes eating bamboo, but not as the giant pandas in the zoo keepers to feed their fruit. Wild panda anecdotes: in recent years, scientists found hidden cameras, male wild pandas left a breath marks on a tree, will lift a leg, like a male dog, and then the urine to the heights of the tree and. The higher the urine, the higher the social status of the male giant panda. Good play! Just like a dog! This is fun. Ax mountain in north of the city, we established a lush bamboo sea and the forest, form different from downtown chengdu "microclimate", in 1987, formally completed, now has developed into a specialized in endangered wildlife research and breeding, protection of education and education tourism, a nonprofit organization.

Do you know how pandas digest bamboo? Researchers have found that the giant pandas digestive tract is short and simple, and there is no such thing as a long, plant-eating animal with a thin gut and a complex stomach or a developed cecum. In addition, the giant pandas genome sequences announced in 2009, after they found the giant panda to the lack of some help in the digestive tract herbivores digest cellulose and hemicellulose (they are the main components of the fibrous plant diet) enzymes. This is confusing for researchers, and how does the lack of these necessary conditions digest bamboo?

Researchers use of gene sequencing technology, analysis of more than 5000 ribosomal RNA sequences, eventually in the giant panda, found a variety of digestive tract bacteria and some microbes are very similar to grazing animals. These help animals digest cellulose in their bodies, and seven of them are unique to the pandas digestive tract. Bye bye!

Marine biological environment is a complex system including sea water, sea

water, soluble matter and suspended matter, seabed sediments and marine

organisms. The rich biological resources, mineral resources, chemical resources

and power resources in the sea are indispensable human resources treasure

houses, which are closely related to the survival and development of

mankind.

At present, the main objective of marine conservation is to protect marine

biological resources so that they can not be exhausted for sustainable use by

mankind. In particular, priority should be given to the conservation of marine

animals that are valuable and endangered. According to the UN investigation, due

to overfishing, mangrove accidental killing of non target to allow the killing

of marine organisms, the coastal engineering construction, deforestation,

pollution of the marine environment in general, at least 25 of the worlds most

valuable fisheries resources consumed, whales, sea turtles, manatees and many

other marine animal faces the danger of extinction. It is expected that with the

expansion of marine development, it is possible to cause more damage to marine

biological resources.

Marine protection task should first stop on the marine biological resources

excessive use, secondly to protect the marine biological habitat or habitat,

especially their migration, spawning, feeding, avoid Huahai coastline, beaches,

estuaries, coral reefs, to prevent heavy metals, pesticides, oil, organic

produce and eutrophication. Nutrients such as marine pollution. Maintain the

ability of regeneration of marine biological resources and the natural

purification ability of the sea water, maintain the marine ecological balance,

and ensure the sustainable development and utilization of the marine.

Protection of the Environment

Once man did not have to think about the protection of his environment. There were few people on the earth, and natural resources seemed to be unlimited.

Today things are different. The world has become too crowded. We are using up our natural resources,and polluting our environment with dangerous chemicals. If we continue to do this, human life on earth will not survive.

We realize that if too many fish are taken from the sea, there will soon be none left. Yet,with modern fishing methods, more and more fish are caught.We know that if too many trees are cut down, forests will disappear. Yet, we continue to use powerful machines to cut down more and more trees. We see that if rivers are polluted with waste products, we will die. Yet, waste products are

still put into rivers.

We know that if the population continues to rise at the present rate, in a few years, there wont be enough food.What can we do to solve these problems?

If we eat more vegetables and less meat, there will be more food available. Land for crops feeds five times more people than land where animals are kept.

Our natural resources will last longer if we learn to recycie them.

The world population will not rise so quickly if people use modern methods of birth control.

Finally, if we educate people to think about the problems we shall have a better and cleaner planet in the future.

今天，我们读了很多关于保护环境的小短文。我想起曾经在我身边发生的事情。

记得是去年的暑假，我和爸爸一起去鹅湖边散步，走了一段路，我就一个劲的喊口渴，于是，爸爸就在路边的小店给我买了根冰棍。我边吃边走，一会儿就吃完了，随手把冰棍棒往鹅湖里一扔。爸爸看见了，马上提醒我说;“可可，不能乱扔垃圾噢!如果每个人都像你一样往湖里扔垃圾，这美丽的鹅湖不就变成了垃圾湖了。”我羞愧的说：“知道了，我下次一定不乱扔垃圾。”爸爸微笑着抚摸我的头说：“地球也是我们的家，我们应该保护它，爱护它，让天更蓝，水更清，草更绿。”我调皮的说：“噢，那就是大家一直说的，城市是我家，环境清洁靠大家。我明白了。”让从那以后，我再也不乱扔垃圾了。

我想爱护环境与每个人息息相关，所以要从每个人做起!

我国是海陆兼备的国家，我们不仅有960万平方千米的陆地，而且还有300万平方千米的海洋。

海洋的面积虽然只有陆地的1/3，但它却是一个宝库，像一个聚宝盆似的。里面有无数的奇珍异宝，海洋是生命的起源，也可以说是生命的母亲，可有些人却对生命的母亲一而再，再而三的伤害她。

海洋里有许许多多的鱼类和植物类，而它们却在慢慢地消失，好像蒸发一样，变得无影无踪。它们大多数并不是因为大自然的伤害而亡，而是一直声称爱它们的人类所亡，人类为了他们自已的利益，为了满足彵们的虚荣心，竟然杀害自已的朋友-----鱼儿。为了表现他们高尚的品质，他们把海洋里的植物移栽到陆地上，如果这些人们不去买这些海洋里的动植物，那就不会有人去捕捉戓杀害海洋里的动植物，就不会害得海底一片狼坝。还有一些人更可恶，他们为了图个方便，竟然把工厂排出的废水废料全部倒进海洋中，害得我们蓝色的国土，生命的母亲，身上到处都是病。她在呼救。

像关于吃鲨鱼翅就有这样一个的故事，一位成功的领导者，上层人士，为了吃鱼翅，不远万里来到海边，却没有吃成。回到家后，那边的人费了九牛二虎之力终于抓到了一条鲨鱼，便空运给彵，他乐滋滋的尝着那美味的鱼翅，可他没有想过那是一条鲨鱼换来的。唉!

海洋有时也会发脾气，但全是因为那些没有公德心的人害的，据人统计，每个世纪，在海上出事的船大约为2700艇。但人们并没有因为海洋的睥全而停正伤害她，反而愈演愈烈了，又因为出事的轮船上有许多的值钱的物品，一些人便开始下海找这些宝藏，人们无意中发现海洋里有石油，天然气，多金属结核，金红石等宝臧，这些珍贵的宝藏使人们开始更加疯抂的挖掘，海洋因此变得千疮百孔。也许她让这些货船出事故，就是在警告我们別在伤害她了。

Animals are friends of human beings, everybody is responsible for animal protection, we should take good care of them. Because, there are a lot of insects are beneficial to human. For example: the bee, it is industrious, very early in the morning to go out honey, again and again. In the dark, after the bite honey, non-stop to adopt to carry on the processing of honey. The appearance of the bees and ordinary, life is very short, only about 3 months, Can it all his life not rest, work diligently, and them nothing in humans, but for people to make sweet and delicious, nutritious, honey can cure sickness.

And the frog, the frog is covered with green clothes, two big eyes, like two stars glittering and translucent and transparent glass ball, it hid in the field, only eat insects, protect crops. Two a push with its back when it catch insects, a jump, nimbly hind legs up, jump up high, long tongue out, like a vacuum cleaner quickly eat insects to the stomach. But we humans can use them as delicious food on the table.

There are many lovely animals, my favorite is the giant panda. The giant panda is our precious animals, my mother told me that the giant panda is a national treasure of our country! Long giant pandas are cute, chubby, plump, start to counteract a, particularly funny. Its head and body are white, only the rim of the eye, ear, and the shoulder is dark brown. Especially that a pair of black rim of the eye, long in white face, like wearing a pair of sunglasses, plus the clumsiness and start to look in all directions, looks like a little gentleman.

You look! They are adorable, they are our humans good friends, how are we going to have the heart to hurt them?

动物是人类的朋友，保护动物人人有责，我们应该爱护它们。因为，有很多昆虫都对人类有益。比如说：蜜蜂，它很勤劳，每天早上很早就出去采蜜，一次又一次。到了天黑，吃几口蜜糖后，就马不停蹄地对采来的蜜进行加工。蜜蜂的外形并不起眼，生命也很短暂，只有3个月左右;可它一生都不休息，勤勤恳恳地工作，它们对人类毫无所求，却为人们酿造了甘甜可口、营养丰富、可医治病痛的蜂蜜。

还有青蛙，青蛙披着碧绿的衣裳，两只大眼睛，像两颗晶莹透明的玻璃球，它藏在田里，专吃害虫，保护庄稼。它捉害虫的时候两条后腿一蹬，一纵身，敏捷地将后腿一蜷，跳起老高，长长的舌头一伸，就像一个吸尘器一样转眼就把害虫吃到肚子里去了。可是，我们人类却把它们当成美味佳肴摆在餐桌上。

还有许多可爱的动物，我最喜欢的是大熊猫。大熊猫是我国珍贵的动物，妈妈告诉我大熊猫还是我们国家的国宝呢!大熊猫长的很可爱，胖乎乎、圆滚滚的，走起路来一摇一晃的，特别逗人。它的头部和身体都是白色的，只有眼圈、耳朵和肩部是黑褐色的。特别是那一对黑黑的眼圈，长在白白的脸上，像是戴着一副墨镜，加上那笨拙的动作和走起路来东张西望的神情，显得像个小绅士。

你瞧!它们多么可爱，它们是我们人类的好朋友，我们怎么忍心伤害它们呢?

Animals are natural resources that people have wasted all through our history.Animals have been killed for their fur and feathers， for food， for sport， and simply because they were in the way.Thousands of kinds of animals have disappeared from the earth forever.Hundreds more are on the danger list today.About 170 kinds in the United States aloneare considered in danger。

Why should people care? Because we need animals， and because once they are gone， there will never be any more。Animals are more than just beautiful or interesting.They are more than just a source of food.Every animal has its place in the balance of nature.Destroying one kind of animal can create many problems.For example， when farmers killed large numbers of hawks， the farmers stores of corn and grain were destroyed by rats and mice.Why? Because hawks eat rats and mice， with no hawks to keep down their numbers， the rats and mice multiplied quickly。

Luckily， some people are working to help save the animals.Some groups raise money to let people know about the problem.And they try to get the governments to pass laws protecting animals in danger.Quite a few countries have passed laws.These laws forbid the killing of any animal or planton the danger list.Slowly， the number of some animals in danger is growing。
