+ 加入清单As we all know, pollution is harmful to living beings. There are many different types of pollutions in this world. For instance, water pollution, air pollution, noise pollution and so on. Water pollution cause many kinds of disease that have negative effects on human beings, sometimes the diseases will take people’s life away. Dirty air will increase the rate of getting lung cancer. While the noise pollution will cause insomnia. People’s health condition will be damaged.
In my humble opinion, people should take measures to control the pollution. Recently, not only the government, but also individual has taken part in the action of protecting the environment. This is a good sign. Rivers are being cleaned, air is purified, and the people come to realize that the importance of protecting the environment.
However, this is not enough, the problems are still exist. Not all of them have been solved. Some factories are still pouring dirty water into the rivers or give off the toxic gas into the sky. We should know that protecting the environment needs everybody’s effort.

+ 加入清单In fact, there are many things that can seriously pollute the environment: litter, spitting, grass and so on. The consequences are severe. But the waste of resources cannot be ignored. The worst is the waste of water.
At present, the reform and development of our country is at a critical juncture, and we should strive to achieve the goal of building a moderately prosperous society in all respects. But there are still some problems -- our living environment is seriously polluted; And the green resources are falling.
We do a lot of what the environment, such as: on one occasion, in a clean small garden, there have been some rubbish, gradually where there are a lot of people throw garbage, there is a garbage dump. It turned out that the trees were green and the flowers and grass were blooming. The bees and the butterflies were there, and there was a smell of enchantment. But now, there was nothing to do with it, and the smell of it was so bad that no one was willing to stay there any longer. Alas! It is a pity that such a beautiful garden is gone. If people notice that they dont pollute the environment, now, by the way, its a kind of escape. And, what a wonderful thing for people to have a rest and take advantage of the cold. But now its a junkyard, and the consequences of polluting the environment are terrible.
And there are a lot of factory waste is also pollute the environment, but the most serious is the pollution of water, I heard of such a story: there was a village, there was a clear pool. There were lotus flowers in the water and the goldfish, and it was so beautiful that visitors to the village would not forget to take a look at the scene. And people in the village wash and cook and drink water and water, so the water is very precious. One day, a businessman opened a factory near the pond, and the factory shut down a lot of waste water and garbage and went into the pond... The result can be imagined: the goldfish died, the water side became the sewage, the tourists no longer came, the people in the village moved away... Alas! The little pond has disappeared. The factory severely polluted the environment and made the environment in the village very bad and affected peoples lives. Its a story, but there are a lot of these things in everyday life, and the results are very serious, not just simple consequences.
In fact, there are many things that can seriously pollute the environment: litter, spitting, grass and so on. The consequences are severe. But the waste of resources cannot be ignored. The worst is the waste of water.
Now, Beijing is a city of severe water shortages, but there are a lot of people in the waste water, such as: there are a lot of people out of the water to wash the dishes and laundry water and reuse. In fact, although can only save a little water, economy is a lot of!
Also, people who sell fish in the market love to put a faucet on the side of the water, and when they use water, they will let the water flow freely. How much water they would waste if they went on like this!
The drink, the wine, etc., are now made with water. Some factories use a lot of water, so some of the water is wasted. Thats a lot of wasted water. This water can do a lot if you save it! You can also avoid a little water.

+ 加入清单Nowadays, with the improvement of the people’s living standard, some people form a habit of raising small or domestic animals as pets. Some raise small dogs or cats as their pets while others raise various birds or fishes as their pets. There are still even some people raising snakes and other unusual animals as their pets.
Does anyone have the same opinion of raising animals as pets? No, some people object to the idea of raising animals as pets. To them, animals have their own right to live a natural life like human beings. On the other hand, the way people raise animals as pets have a negative influence on the surroundings such as dogs’ barking at midnight, dogs’ chasing people on the street and so on. What’s more, some animals will transmit some diseases.
In my opinion, I do not like the idea to raise animals at pets. Animals have their own right to lead a life as they like. We should not deprive them of their natural right. In this way, we will live in a peaceful world in harmony with the other living creatures.
如今,随着人们生活水平的提高,有些人养成了饲养小动物或家畜作为宠物的习惯。一些养小狗或猫作为他们的宠物,而其他人饲养各种鸟类或鱼类作为他们的宠物。甚至还有一些人饲养蛇和其他不寻常的动物作为他们的宠物。
任何人都有相同的意见,饲养动物作为宠物吗?不,有些人反对将动物作为宠物饲养。对他们,动物有他们自己的权利,生活像人类一样自然。另一方面,人们饲养动物作为宠物的方式对环境有负面影响,如狗的叫声在半夜,狗追逐人在街上等。更甚的是,有些动物会传播某些疾病。
在我看来,我不喜欢养宠物。动物有他们自己的权利,过他们喜欢的生活。我们不应该剥夺他们的自然权利。这样,我们将生活在一个和平的世界中,与其他生物和谐相处。

小小的身体里总是蕴含着大力量,这句话形容咱家的“狮子”再合适不过了。别看它身形小,抢夺食物的战斗力,绝不亚于万首之王——老虎。所以,我给它喂食好,便将食物放在饭桌上,以免被他吃光。

它先是掂量似的蹦哒了几下,见够不着,就先往后退了3步,像跳高运动员似的向前冲刺,在临近桌脚的地方奋力一跳,可惜了,还是差一点儿,可它并没有灰心,不知从哪儿找来了糖果盒子。一步一步的拖向桌角旁,它跳上去,摸到了椅子的坐垫,此刻,它多么希望自己能长高点啊!这样就可以跳上椅子,享用美食了,真是太悲哀了。它气鼓鼓的跳下盒子,用幽怨的眼神环视着房间各个角落,跑去搬来了我早已丢弃的眼镜盒。它开心的围着眼镜盒转了几圈飞快地推向了糖果盒并十分费力的将眼镜盒推上去。
它兴奋地站在眼镜盒上,扑向椅子,站在上面的它威风凛凛,时机已到。只见它十分灵巧地跳向猫粮,两颊仿佛泛着红晕,棕色的眼睛里闪出奇异的光芒,体态极其优美像极了专业的芭蕾舞演员,嘴巴微微张起,两只爪臂张大,爪尖上锋利的指甲早已展露出来,四处扭动,身上的每一个细胞都告诉了我们它抢夺的决心,只可惜,天有不测风云,它抓到的不仅仅是猫粮,还有猫粮的包装袋,所以,由于包装袋承受不了如此沉重之物,“嘭”,袋子掉下来了,“喵——喵——喵”我随着猫叫声,走出来,“狮子”只是摔在柔软的椅垫上,地上则一片狼藉。
我十分无奈:你啊你,真是一只活生生的大狮子!

As is often read in the newspaper reports, wild life especially the rare species are threatened with extinction. Human beings are making attempts to hunt wild animals for a big profit, which, of course, results in a sharp decrease in the number of animals.
Therefore, it is high time for us to take quick action to protect them. First of all, it’s quite necessary for every citizen to realize the importance of animal protection. Only by knowing its importance can people develop a sense of responsibility. In addition, the government should pass some laws to forbid any hunting of rare animals.
If I were one of the endangered animals, I would hope that man could be a good friend of mine rather than my enemy.

因此,是时候为我们迅速采取行动来保护他们。首先,它是非常必要的对于每一个公民意识到保护动物的重要性。只有通过了解它的重要性人们可以开发一种责任感。此外,政府应该通过一些法律来禁止任何捕猎珍稀动物。

In this world there are ten million species of creatures, they get along, together in this live on the earth like a sapphire, tens of millions of years, too, will not change. But there is a kind of biological change the world, it is in this world with his proud technology to kill themselves, it is human. Human beings in this world only live for one million years, but it such as brute kills life on earth! In 2009, the Indian da-hong ruined homes of five million people in one hundred; In 2010, the Haitian earthquake left two hundred and thirty thousand people dead, according to estimates that by the year 2050, there will be two hundred and fifty million ecological refugees, we use our knowledge to kill themselves, as a human, I think its ironic.
The earth is in the vast universe, the only planet to harbor life, originally the earth is green hills and water, a piece is abundant, but todays earth after hurricanes, forest fires and drought in high temperature, is about to collapse, the earth began to shout for us, in the 2010 years, the earth has used its roar to kill two hundred and thirty-six thousand people, the earths voice we should hear, or the end of the world will come in advance.
Close to one end of the alarm, have "lungs of the earths forest gradually reduce, the earth began to collapse, there is only one earth, and this one belongs to you, rather than a human, the earth is our refuge, we should find a balance point and the earth coexistence, reduce the anger of the earth, let the human is no longer increase driver disaster, let us have a better living environment, but also for generations to leave some more living space.
我们的世界本来是青山绿水,汪洋的大海是湛蓝的,广阔的天空是蔚蓝的,我们居住的地球有太多美景,让我们不禁要赞叹这世界的美丽。
在这个世界上有千千万万种的生物,它们相处融洽,一起在这如蓝宝石般的地球上生存,过了几千万年也是一样,不会改变。但是有一种生物的出现改变了整个世界,它在这个世界用自己引以为傲的科技杀死自己,它就是人类。人类在这个世界上只生存了百万年,但是它却如猛兽般的杀死地球上的生物!在二零零九年时,印度百年大洪水毁了五百万人的家园;二零一零年,海地大地震让二十三万人死亡,根据估计,到了二零五零年,将会有二亿五千万名的生态难民,我们用我们的知识杀死自己,身为一个人类,我觉得很讽刺。
地球是在浩瀚宇宙之中,唯一能孕育生命的星球,本来的地球是青山绿水,一片盎然,但是现今的地球经过飓风、森林大火和高温干旱等严酷的考验,已经快要崩毁,地球开始对我们怒吼,在二零一零年时,地球已经用它的怒吼害死了二十三万六千人,地球的心声我们应该要听见,否则世界末日将提前来临。
末日的警钟一分一秒的接近,有“地球之肺”的森林逐渐的减少,地球开始崩毁,地球只有一个,而且这一个属于大家,而不是人类的,地球是我们的庇护所,我们应该找到一个和地球共存的平衡点,减少地球的怒气,让人类不再是加重灾难来临的推手,让我们有更好的生活环境,同时也替后代子孙多留一些生存空间。
篇15:写濒临危机动物的英语作文北极熊
全文共 3755 字
+ 加入清单When the Arctic Ocean freezes over in the autumn, polar bears set off in search of their favorite meals: fatty ringed seals and bearded seals. By the summer, the sea ice begins to melt and break apart. Deprived of access to the tasty seals, polar bears spend the summer fasting. At least, thats whats supposed to happen. As the planet warms, the warmer ice-free season is getting longer and longer. So whats a hungry bear to do?
Scientists once thought that polar bears might survive by supplementing their pinniped diet by turning to terrestrial foods like snow geese, their eggs and caribou.
"Weve had this debate in the literature about whether terrestrial foods are nutritionally relevant to polar bears during the on-land season when the ice has melted."
University of Alberta biologist Nick Pilfold.
"And weve known for a long time, going back to research in the early 70s, even going to back to early explorer logs, that polar bears will consume terrestrial based foods. But the debate was always whether those foods actually add up, energetically." In other words, do these substitutes provide enough nutrition to make up for the lost seals?
To find out, Pilfold and his colleagues estimated the weight lost each day by polar bears in the wilds of western Hudson Bay during the ice-free season, when they could ostensibly be chowing down on terrestrial foods. Then they compared that to the weight lost by bears that are temporarily held in Manitobas Polar Bear Alert Program.
While captive, the bears do not eat. They drop about one kilogram each day. But the wild bears, who had access to the Arctic snack bar, lost the same amount of weight each day. The results are in the journal Physiological and Biochemical Zoology.
"Which is really saying that the terrestrial foods do not have dense enough energy to offset the mass loss. So this idea that bears can just switch from eating sea ice–based food to land food and thats going to help supplement against longer ice-free seasons, that really doesnt show up in the data."
The problem is that polar bears evolved to rely on the marine diet.
"The food on land is protein and carbohydrate based, and the food the polar bears really focus on is fat. Fat is the name of the game for these bears; theyre highly adapted to absorbing that fat into their system and putting it onto their body as body mass, so they can fast on it later on. And the only thing thats going to provide them with that type of fat are marine mammals. And they can only access those marine mammals when theres sea ice."
Adult males can go eight months without food. But younger, sub-adult bears, which are no longer nursing and must hunt, cant last as long without sea ice. So as the Arctic warms, younger polar bears will disproportionately die out. Leaving the species survival in doubt.
北冰洋在秋季结冰以后,北极熊就会出发去寻求它们最喜欢的食物:富含脂肪的海豹和胡子海豹。海冰在夏季开始融化断裂。这使北极熊在夏季无法吃到美味的海豹,所以它们进入禁食期。至少,情况应该是这样。但是由于地球变暖,温暖的无冰季节越来越长。那饥饿的北极熊要怎么办?
科学家曾经认为,北极熊可能会转向陆地上的食物来补充它们对鳍足类动物饮食的需求,进而生存下去,这些陆地食物包括雪雁、雪雁蛋和北美驯鹿。
“文献中有过这类辩论,即在寒冷融化时陆地食物是否能满足北极熊的营养需求。”
尼克·皮尔福德是加拿大阿尔伯塔大学的生物学家。
“通过上世纪70年代初的研究,还有早期的探险者日志,我们很早以前就知道,北极熊会以陆地食物为食。但是辩论的焦点在于,这些食物是否能增加北极熊的能量。”换句话说,这些替代食物能否为北极熊提供足够的营养,弥补不能进食海豹带来的损失?
为了解开这个疑惑,皮尔福德及同事对西哈德逊湾荒野地区的北极熊在无冰季期间每天失掉的体重进行了估算,从表面上看,北极熊在这段时间食用了陆地食物。随后,他们将这一数据与通过马尼托巴北极熊预警计划暂时捕得的北极熊所失掉的体重进行了对比。
在被关期间,北极熊不吃东西。它们的体重每天大约下降1公斤。虽然野生北极熊能享用北极“小吃”,但是它们的体重每天也同样会下降1公斤。这一研究结果发表在《生理学和生化动物学》期刊上。
“显然结果表明,陆地食物不能为北极熊提供足以抵消大量损失的能量。所以,北极熊可以从食用海冰下面的食物转向食用陆地食物,并帮助它们对抗日益延长的无冰季这个观点,并没有在这项数据中得到证明。”
问题是,北极熊进化成了依靠海洋食物的动物。
“陆地食物以蛋白质和碳水化合物为基础,而北极熊需要的食物以脂肪为主。脂肪是这些熊真正需要的东西;它们高度适应的情况是,将脂肪吸收进它们的系统中,然后把这些脂肪放在身上以增加体重,这样它们之后就可以依靠这些脂肪来度过禁食期。唯一能提供给北极熊这种脂肪的就是海洋哺乳动物。但是它们只能在有海冰时食用到这些海洋哺乳动物。”
成年北极熊可以8个月不进食。但是小一些的未成年北极熊已经不再被哺育,它们必须要去猎食,可是它们不能在漫长的无冰季期间一直不进食。所以,随着北极地区变暖,较小的北极熊将会大批死亡。这使这些物种的生存成为问题。

环境污染会给生态系统造成直接的破坏和影响,如沙漠化、森林破坏、也会给生态系统和人类社会造成间接的危害,有时这种间接的环境效应的危害比当时造成的直接危害更大,也更难消除。例如,温室效应、酸雨、和臭氧层破坏就是由大气污染衍生出的环境效应。这种由环境污染衍生的环境效应具有滞后性,往往在污染发生的当时不易被察觉或预料到,然而一旦发生就表示环境污染已经发展到相当严重的地步。当然,环境污染的最直接、最容易被人所感受的后果是使人类环境的质量下降,影响人类的生活质量、身体健康和生产活动。例如城市的空气污染造成空气污浊,人们的发病率上升等等;水污染使水环境质量恶化,饮用水源的质量普遍下降,威胁人的身体健康等。严重的污染事件不仅带来健康问题,也造成社会问题。随着污染的加剧和人们环境意识的提高,由于污染引起的人群纠纷和冲突逐年增加。

保护环境英语作文篇3
People like to modernize the building compared to the magnificent, then this embodies a high degree of spiritual civilization and material civilization of the building should stand in what kind of environment? If the sky filled with smoke, the earth vegetation and so on, this is the people of the modern society of it? No, no, it is the irony of history, this is the tragedy of mankind.
People live on earth, to survive, to develop, first of all have to rely on the earth, by mountains and water, there are grassland nature of the forest. But some people mistakenly believe that nature is inexhaustible treasures, so deforestation and species, dried Ze and fishing, and even by the natural punishment and not know. Year after year, the forest into a barren hills, oasis into a desert, resulting in the world every year, 2,000 hectares of farmland was swallowed by the desert. So go after a few years, the earth will be all occupied by the desert green, our children and grandchildren will not survive! A few years ago, the rural package to the household, coax the mountain into the wind, Chinas Wuchuan County, a township of nearly 2,000 acres of fir forest, cut in a week for the ground. Hearing this news, I have a headache, I am angry, the farmers doing so are too ignorant and too selfish. There are a lot of things that are doing the same thing: it is the smoke of the sky, so that the noise of high decibels can stimulate the nerves of the people.
In this regard, we should think deeply. Modern society makes us live better, modern science has also fully revealed the importance of environmental protection. Every honest citizen should have such a historical vision and sense of urgency: to build our country into an ideal modern power, we must do the development of economic and environmental protection simultaneously, to achieve economic development and social benefits of unity.
人们喜欢把现代化比作宏伟的大厦,那么这座凝聚着高度精神文明和物质文明的大厦应矗立在怎样的环境之中呢?如果天空烟雾弥漫,大地草木枯败等等,这是人们心中的现代化社会吗?不,不是,这是历史的讽刺,这是人类的悲剧。
人生活在地球上,要生存,要发展,首先就得靠地球,靠有山有水,有森林有草原的大自然。可是有人误以为大自然是取之不尽,用之不竭的宝库,于是毁林而种,竭泽而渔,连连受到自然的惩罚而不自知。年复一年,森林变成了荒丘,绿洲沦为沙漠,致使世界上每年有2000公顷农田被沙漠吞噬。这样下去经过若干年,地球上的绿地将全部被沙漠侵占,我们的子孙将无法生存!前些年,农村包产到户后,哄砍山林成风,我国务川县一个乡的近2000亩杉木林,在一周之内被砍为平地。听到这个消息,我头疼,我愤怒,这样做的农民太愚昧,太自私。还有很多正在干着类似务川的贻害子孙的事情:任滚滚浓烟弥漫天空,让高分贝的噪音刺激人的神经。
对此,我们应该深思。现代化社会使我们生活得更美好,现代科学也已充分揭示了环境保护的重要性。每个正直的公民,都应具备这样的历史眼光和忧患意识:要把我国建成一个理想的现代化强国,必须做到发展经济与保护环境同步,实现经济发展效益与社会效益的统一。
事实也是这样,几年前,大连污染严重,经过一系列的保护措施后,不仅使市容面目美观了,还带来了良好的经济效益,外商投资,中外合作等等,因此让大连成为现代化的大都市。
让我们伸出自己的双手,来保护自己的家乡,来建设自己的家乡吧。

菜市场里全都是叫卖声,卖白菜喽,卖青菜喽,卖青蛙喽。我一听有青蛙卖,我就拉着妈妈兴奋地去看青蛙。妈妈看见这里的青蛙又肥又大,就说:“你想不想买几只青蛙尝尝?”我点了一点头。妈妈看见我在点头,就对卖青蛙的人说:“老板,给我挑几只大一点的青蛙!”我高高兴兴地买了几只青蛙回家了。
我刚想把青蛙煮了,可是旁边却听见爸爸低沉地说:“孩子,你必需把这些青蛙放掉!”“为什么?”我很不情愿地说。“因为青蛙是益虫,它7月份一共能吃掉害虫20000多只而且还能保护农作物因为不管是飞的爬的,躲在地下的,它们只要一出来活动,就都被青蛙吃掉而且青蛙对人类的益处很大,如果捕杀青蛙就回让害虫大量的繁殖,我们就必需要大量是用农药来杀死害虫,这样不仅破坏了生态平横而且还污让了环境因此严禁捕食青蛙!所以,你必需把这些青蛙放掉!”
我从爸爸斩钉截铁的口气中,我知道我以经再也没有什么可以商量的余地了。我只好跑到河边,把青蛙放掉了。我看这那几只青蛙用四条着强劲又力的大腿往河中央游去。我叹了口气,心想:我这辈子再也买不到这么大的青蛙了。
真的,我从那以后,我再也没有买到过这么大的鱼了。可是那天的情景却一直铭刻在我的记忆里,爸爸坚定的话语也一直回响再我的耳边。

Now, twenty percent of the people on earth every year are killed by drinking contaminated water, and if this continues, will the earth become bare after tens of thousands of years, like the moon?
According to the statistics of scientists, every year, more than 20 percent of the trees are withered by exhaust pollution every year. More than eighty percent of our useful bacteria die, and everyone may feel very exaggerated, but it is true. Followed by contaminated waste water, waste gas and so on. Is human error?
How much I hope that we can cherish every thing around us, every animal, every beneficial bacteria, because it is possible, in tens of thousands of years later today, they are gone.
Animals have warned against humans;
Bacteria have warned against humans;
Every innocent life warned us.
"Human, do not harm yourself, do not kill us again!"
随着科技的不断发展,汽车的不断增多,排放的废气已经造成了严重的污染,或许,几年后的子孙后代、几百年后的大家,或许会因为大气污染而死亡。现在,地球上每一年都有百分之二十的人因为饮用了受到污染的水而死亡,如果这样延续下去,地球在几万年后岂不是变得光秃秃、像月球一样了?
据科学家的统计,每一年,每一月都有百分之二十多的树木因为废气污染而枯萎。百分之八十多对我们有益的细菌死亡,大家或许会觉得很夸张,但这是事实。其次还有受到污染的废水、废气等。人类有错吗?
我多么希望大家能珍惜我们身边的每一个事物,每一只动物,每一只有益的细菌,因为,很有可能,在几万年后的今天,他们都没有了。
动物对人类发起了警告;
细菌对人类发起了警告;
每一条无辜的生命对我们发起了警告。
“人类,不要再害你自己,不要再害死我们了吧!”
