保护濒危动物的英语作文八十字左右【推荐20篇】

In the past, there have been many endangered animals. Now they are extinct. Does it matter? Has our environment been affected by their absence? Has the quality of our own life been changed? The answer to these questions is "Yes."

Yes. It does matter if we destroy an endangered species habitat to develop more farmland, housing or industrial parks. There is a delicate balance of nature. If one small part is removed, it will effect all the other parts. For example, if certain trees are cut down, bats will have no place to roost. If they cannot roost, they cannot breed. If there are no bats, there will be no animal, or bird to eat certain insects that plague our crops.

Yes. Our environment has been affected by the absence of certain animals. Certain flowers are pollinated by butterflies, which migrate from Canada to Mexico. Some of the breeding grounds of these butterflies were destroyed. Now these flowers are disappearing from certain areas. We will no longer be able to enjoy their beauty.

Yes. The quality of our life has been changed America used to be covered with giant trees. Now we have to visit them in one small park. Rain forests around the world are being cut down to make room for humans. We will never be able to see or study this fragile ecosystem.

I would encourage us humans to look for other alternatives for our farmlands, housing, and industries. We have alternatives; the animals do not.

在过去,有许多濒危动物。现在他们正在灭绝。关系呢?我们的环境已经受到他们的缺席?我们的生活质量已经改变了吗?这些问题的答案是“是的。”

是的。没关系如果我们摧毁一个濒危物种栖息地开发更多的农田,房屋或工业园区。有一个微妙的平衡。如果一小部分被删除,它将影响所有其他部分。例如,如果某些树木砍伐,蝙蝠没有栖息的地方。如果他们不能,他们不能繁殖。如果没有蝙蝠,不会有动物或鸟吃某些破坏庄稼的昆虫。

是的。我们的环境已经受到缺乏某些动物。某些花授粉的蝴蝶,从加拿大到墨西哥迁移。一些这些蝴蝶被毁的繁殖地。现在这些花从某些地区消失。我们将不再能享受他们的美丽。

是的。我们的生活质量已经改变了美国曾经覆盖着大树。现在我们要拜访他们在一个小公园。世界各地的热带雨林被砍伐,为人类。我们将永远无法看到或学习这个脆弱的生态系统。

我将鼓励我们人类去寻找其他替代品对于我们的农田,住房,和行业。我们选择;动物不会。

Protect environmental health and build a good home -- speech

The teachers! The classmates! Everybody is good! My topic today is "protecting the sanitation of the environment and building a beautiful homeland."

We live on earth, and the earths environment is protected by everyone. Head is LanYingYing day, is at the foot of green land, the majestic beauty of high mountain, the flow of water on the bottom, the tall green trees, the bright beautiful flowers, the earths favor of human is so beautiful environment, we can feel life here is very comfortable and happy, some people, however, not only protect the environment, also damage the environment, this is what a shameful act.

Currently, yichang is creating a national health city. There is no national health city in hubei province, but there are national health cities in the underdeveloped areas of the west. The city of yichang province, the world three gorges dam and ge zhou dam are located in yichang, the golden three gorges, the silver dam, the green yichang. The beauty of the mountain.

In the second half of last year, we started the "triple town" campaign and should start from me. Now the streets are littered with litter, spitting and scribbling. The dustmen tore up the rubbish ads, the people secretly taped up, and the people scrawled on the walls with paint, called the "psoriasis" of the street. These dirty and messy phenomena and to be governed.

The three orders of the state have led to the prevention and reduction of pollution and pollution, and the protection of air and environment. Now there are more and more cars, and the emissions are getting worse and worse. There are factories, sewage, pollution and water quality that directly harm crops and live life.

What is the benefit of this environmental destruction, and the destruction of the environment? Teachers, students, and to strengthen the awareness of environmental protection, improve their quality of civilization, actively join the "tri-cities lianchuang" activities, must start from me, starts from the minor matter, do a civilized, townsfolk hand in hand to build better homes!

My Views on Environmetal Protection

Nowadays, the world we live in is becoming more and more intolerable because of environmental destruction. Each day thousands of tons of gases come out of the exhausts of motor vehicles. Smoke from factories pollutes the air of industrialized areas and the surrounding areas of the countryside. Recently,haze weather has become a usual phenomenon here in large part of China. People are forced to wear the mask to avoid breathing poisonous air. Some people think it is impossible to solve the problem,however,from my opinion,if we find out the reason and take effective measures the environment can be better.

If we trace the cause for haze weather,the main points are as follows,first,our countrys air quality standards are rather lax and evaluation factors are limited,so you will see that current air appraisal system has defects. Second,some people just go for economic interests instead of turning out products according to relevant law and regulations. They tend to use obsolete equipment in which they are more likely to emit a great deal of wasted air. Third,across our society,the awareness of protecting the environment has not built up so that people havent formed a habit of using green product and saving energy as much as possible. If we dont take action to show respect to the environment, we will have to face an increasingly awful situation.

Therefore, effective measures should be taken and laws passed to conserve the environment. In my opinion, to protect the environment, the government must take even more concrete measures. First, people should be educated to recognize the importance of the problems, to use modern methods of birth control, to conserve our natural resources and recycle our products. Second, much more efforts should be made to put the policy of population into practice, because more people mean more pollution. Finally,laws concerning environmental protection should be put into effect and enforce strictly just as our government has been doing. To sum up,if we work together to take out such measures,our environment will get better and better and haze weather will vanish completely.

The earth is our home. We must protect it, do not polluted it. To attain low carbon life, actually very simple.

地球是我们的家。我们必须保护它，不要污染它。达到低碳生活，其实很简单。

The scientists found that at least 100 kinds of environmental harm atmospheric pollutants, including so2, nitric oxide, carbon monoxide and hydrogen fluorine hydrocarbon etc on human body has great harm. Industrial production and transportation exhaust gas and dust is the main way if atmospheric pollution. Industrial waste gas of the dust particles would adsorption many poisonous and harmful substances, these pollutants in the atmosphere will produce all sorts of chemical reaction, generate more contaminants, second pollution formed. Atmospheric pollutants in the air accumulated in air quality declining, directly harmful to human health, and make ozonosphere being damaged, cause global warming. Environmental problem has become a global problem, even influenced the survival and development of mankind. Latest research shows that when people in Nineveh is virtuous orchid climate mutation of extinction.

科学家发现，至少有100种不同的环境危害大气污染物，包括二氧化硫，一氧化氮，一氧化碳和氢氟烃等对人体有很大的危害。工业生产和交通尾气烟尘是造成大气污染的主要途径。工业废气的尘埃会吸附许多有毒有害物质，这些污染物在大气中会产生各种各样的化学反应，产生更多的污染物，形成二次污染。在空气中积累在空气质量下降的大气污染物，直接危害人类健康，使臭氧层受到破坏，导致了全球变暖。环境问题已成为全球性的问题，甚至影响到人类的生存与发展。最新研究表明，当人们在尼尼微是尼德兰气候突变的灭绝。

It is known to everyone that the unrestrained slaughter of wild animals has diminished the number of some endangered species. More and more species are being driven to extinction every year. It is terrible to think that magnificent animals are being sacrificed to human vanity

There are already laws enacted to prevent the importation of rare animals and the products made from their flesh, skin and bones.

These laws must be strictly enforced. Violators of these laws must be severely punished .Moreover, the public must be informed about the natural treasures we stand to lose .If we don’t take immediate action, we will be depriving future generations of our most precious heritage.

In Taiwan, because most people do not understand the importance of wildlife, the wildlife is in a poor situation. We Chinese are fond of eating anything delicious, so there are many animals killed by hunters. People enjoy eating tigers, bears, birds, and lions, so there are fewer and fewer birds flying in the sky and fewer and fewer bears running here and there in the forest. Instead, we often see them for sale at the market. How poor they are! And how cruel we are!

In my opinion, we should try every possible way to preserve wildlife. First, no one is allowed to hurt any wild animal. Second, the authorities concerned should punish those who kill any wild animal. Third, we should pay more attention to those endangered species to protect them from being eaten. If we can do so, nature must become very beautiful.

The existence of the oceans allowed the first life to form, grow, and reproduce. T he oceans create atmosphere, weather, and climate. They supply the world with an abundance of life, much of which sup plies humans, among others, with transp ortation, food, medicines, and recreation . While other species may enjoy the ben efits of the oceans, humans have becom e so wide spread and detached from the world around them that they have effect ively brought the oceans to the brink of extinction in a very short time (Woodard, 2000). While the oceans count time in th e billions of years, humans count time in years or decades. In the last fifteen deca des, human activity has decimated a sig nificant portion of the ocean, creating "d ead zones" where there is no oxygen to support life. The ocean chemistry is beco ming dangerously acidic due to the burni ng of fossil fuels and the dumping of was te in the oceans, and may trigger a non-r eversible chain reaction of extinction, sa y before the end of this century (Global warming, 2006). The goal is to motivate, educate, and offer possible solutions to t he problem, however it will not work unt il people across the globe work together.

dolphins are very clever. people often train them so that they can give a dolphin show which brings people a lot of happiness and joy.

unluckily, the number of dolphins is getting smaller and smaller. because of water pollution, there is less and less space for dolphins. many people make money by hunting dolphins. if we don’t protect them, maybe we’ll lose our good friends one day. as a student, i hope more and more people should take action

s to protect dolphins.

在有益小动物中，我最喜欢的动物是：青蛙、小鸟、蜜蜂等。

青蛙眼睛大大的，又亮晶晶的，绿色的皮肤是它的保护色，不注意看时就跟田里的庄稼一样，四条腿强壮有力又很灵活，游得时候飞快，据说人类的蛙泳，就是仿照青蛙的游泳姿势，是不是可以说青蛙是人类游泳的“导师”呢！

最近，我在书上看到一个叔叔在吃青蛙肉！那时，我真的吓坏了，青蛙是抓害虫的能手，它会用长舌头吃各种田里的害虫，很厉害的，是帮助人类的呀！如果，没有了青蛙，田里的害虫会越来越多，庄稼收成也少了，而且人们用手去抓虫子废时又废力。妈妈还说：有些虫子有毒的，可能还会受伤。

因此保护有益小动物，是我们每个人都义不容辞的责任。

世界上有很多很多的有益小动物需要我们保护。

有益的小动物有哪些呢？比如：青蛙、猫头鹰、壁虎等等。就说蚯蚓吧，蚯蚓可以给树苗松土，让树苗健健康康地成长，让我们人类得到更多的氧气，让空气变得更新鲜，所以我们不能伤害它。想知道我是如何知道它的功能的？请读者继续往下看吧！

有一次，我在爷爷家的后院帮爷爷浇花的时候，忽然，我看到一个红色的东西，吓得猛叫。爷爷还以为出了什么事，急忙跑过来，一看，原来是一条蚯蚓！爷爷告诉我它可以松土。这就是我如何知道的。因为它黏黏的滑滑的，一节一节的，看上去很恶心，所以我不敢摸。

虽然看着蚯蚓恶心，但是它真的是有益的小动物，我们不能伤害它。

亲爱的市民朋友们：

今年是《广东省野生动物保护条例》实施五周年。为大力倡导文明、健康、科学的生活方式，进一步增强市民保护野生动物的意识，在全社会形成拒食野生动物的良好风尚，促进人与自然的和谐，广州市林业局、广州市文明办联合向全市发出以下倡议：

一、关爱动物，保护森林，让茂密的森林成为野生动物的栖息庇护场所;

二、从我做起，不滥食野生动物，树立饮食文明新风尚，不乱捕、不猎杀野生动物，做文明、守法的好公民;

三、各饲养、运输和餐饮企业不非法经营、贩运、加工、制作、销售野生动物及其制品，做绿色、环保、守法的经营者;

四、人人行动起来，积极劝说阻止、举报各类破坏森林、伤害野生动物的行为，做保护生态环境的模范。

让我们携起手来共同努力，把广州建设成为处处鸟语花香、人与自然和谐的美丽花城!

广大村民朋友及社会各界人士：

野生动物资源是自然生态系统的重要组成部分，对维护生态平衡，建设生态文明具有十分重要的意义。我镇及周边地区由于良好的森林植被，成为候鸟迁徙途中的重要停歇地，每年春、秋二季，大批候鸟在此栖息觅食，种类有6大类120多种。常见的杜鹃、山雀、黄椿、花鸡、猫头鹰等等。保护野生鸟类，对于保护生物多样性，特别是对预防和控制高致病性禽流感疫病的传播，保护人民身体健康具有十分重要意义。

《中华人民共和国野生动物保护法》、《中华人民共和国陆生野生动物保护实施条例》、《浙江省陆生野生动物保护条例》等法律法规，明确规定野生动物资源受国家法律保护，任何单位和个人不得非法猎捕、杀害、出售、收购、邮寄、运输、携带、经营、驯养野生鸟类和其它野生动物。禁止任何单位、个人在山上、沿海滩涂、内陆湿地等处张网捕鸟和进行其它破坏野生鸟类资源的行为，对非法捕杀、经营野生鸟类的单位和个人，将依法进行严肃处理，非法捕杀国家一级保护鸟类1只及以上或国家二级保护鸟类3只及以上或国家三级保护鸟类20只及以上，以及窝藏一般鸟类50只及以上的行为，将依法追究刑事责任。

野生鸟类保护工作是一项社会性很强的工作，离不开社会各界的大力支持，更离不开全体公民的积极参与。在此，希望全体村民和社会各界，从我做起、从现在做起，积极参与、支持野生动物保护工作，不破坏野生动物繁殖区及其栖息地，不乱砍滥伐林木，不捕杀野生动物，拒食野生动物，对非法捕杀、经营野生鸟类的行为主动阻止并及时向林业主管部门或市场监管、公安部门检举和控告(举报电话：12316、12119、12315、110)。

二〇xx年十月

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。

Mistreat your animals and someone might take them from you.

Allen （not his real name） is driving north out of Virginia in the middle of the night， with stolen property in the back of his van. But Allen isn‘t a criminal – in fact he normally would never dream of breaking the law.

The “property” he stole is a dog he calls Flash. Allen doesn‘t particularly want Flash – in fact， in a few hours he‘ll drop him off at a stranger‘s house and never see him again. “I couldn‘t just stand by and do nothing，” he explains. “The owner was plainly neglecting the dog， but the police wouldn‘t do anything about it.”

For over a year， Flash had been tied to a tree in front of someone‘s house. “He was sick and malnourished，” says Allen. “More than once I saw [the owner] kick him for no reason at all.” Allen had repeatedly tried to get the owner to take better care of the animal， or to give it away to someone who would. Finally， he took matters into his own hands – in the dead of night， he took Flash off his chain and drove away with him.

Within an hour， Flash had a new license tag and was being treated by a veterinarian who knew better than to ask questions. Pictures of the dog were put up on animal rescue websites， asking for someone to adopt the dog. A couple in New York offered to take the dog， and animal lovers in states along the way agreed to provide transportation.

Nobody can say for sure how many animals like Flash are ‘rescued‘ every year – receiving stolen property is a crime， so rescuers tend to stay in the shadows. But a growing number of empty collars attests to their work as more and more animals find their way to loving homes.

Animals are people friends,they believe that human not to hurt people.But people are constantly harm to them.

We shouldnt do it.We are now protected animal,make it not hurt,to serious blow the killing animals.Because -- we are animals ah,senior animals.If we were to slaughter,and our family?It is the same with animals!

Because we are a family,so please everyone together to protect animal!

Cats are cute animals,they are very special as well.

It has pointy ears, round eyes,little claws,and short but soft fur.Cats like eating fish and mice.They like to keep themselves clean, they do that by licking their fur.Also they are nocturnal animals, they sleep in the daytime and do most of their movements at night.

We should love cat, because cats are our friends,too.

濒危动物是指所有由于物种自身的原因或受到人类活动或自然灾害的影响，而有灭绝危险的野生动物物种。从广义上讲，濒危动物泛指珍贵、濒危或稀有的野生动物。

保护濒危动物的作文400字（一）

我们不应该去破坏他们安详和谐的生活，我们也无权去破坏他们的生活，当然，更没有理由去指责伤害他们。

每当我们的饭桌旁摆上一道道香喷喷的菜，比如：蛇、青蛙、等动物。我们是不是应该想一想，我们每吃一种动物，就等于放走了多少对农民对庄家有害的虫。我们更是不是也应该换位思考一下，它们都在齐心协力的抓害虫，可人类不但不领情，反而把它们当做他们的食物，当作我们人类每天赚钱的东西，他们是多么可恶呀！

如今，地球上的许多生物已经很罕见了，甚至有的已经濒临灭绝了！如果地球上没有了动物，地球将会变成什么样，人类又将会变成什么样？

我想，是我们人类好好反省的时候了，如果再这样下去的话，我们将会成为动物们的敌人了，更别谈什么“与狼共舞”

人类，快点醒醒吧！保护野生动物，现在开始，还来得及！

保护濒危动物的作文400字（二）

动物是人类的朋友。动物离不开人类，同样，人类也离不开动物。

很久很久以前，动物和人类是一对好朋友。他们互相帮助、互相依靠、和睦相处，谁也离不开谁。但是，随着时间的推移，由于人类自身的原因，造成了动物与人类的关系恶化，而且有越来越严重的趋势。

首先，人类对动物的肆意捕杀，一方面造成了动物的大量减少，另一方面也造成了动物对人类的敌意不断增强，一定程度上破坏了动物与人类的友好关系。事实上，一直以来，人类残害动物的行为一直没有停息过，吃孔雀、吃猫头鹰、吃猴脑、吃丹顶鹤、吸熊胆，真是到了“万物皆入口”的地步！您想，这样怎么能不引起动物的愤怒呢？怎么能让动物不挺身而出、奋起反击呢？这也是造成了动物攻击人类、甚至伤害人类生命的重要原因。

其次，随着人类社会的不断进步，人类自身的一些不良行为，不仅破坏了地球环境，也破坏到了动物的生存环境。工厂的污水、汽车的尾气、对森林的过度砍伐等不良行为，都对大自然造成了严重的破坏，同时也对生存在大自然的动物造成了直接的伤害，使动物生存艰难，种类、数量越来越少，破坏了整个生态系统的平衡，最终使人类走向灭亡。

可见，动物与人类的关系已经到了严重恶化的地步，同时，也威胁到了人类自身的生存。人类难道还能这样执迷不悟、不知悔改吗？！我想，人类应该及时改变自身的不良习惯，爱护动物，保护地球环境。

作为一名小学生，我们应该从我做起，从现在做起，爱护我们的大自然，保护我们周围的动物。

让我们大家一起行动起来，爱护动物，善待动物，成为动物的好朋友，为改善动物与人类的关系做出自己应有的贡献吧！

保护濒危动物的作文400字（三）

当你品尝着一盘盘山珍海味时，你是否想过动物们正在一批批的减少？当你捕杀着一只只动物时，你是否听到动物在哭泣呢？美食家们，你们是否能让死去的动物一一复活？捕猎者，你是否能让动物死而复生回归大自然吗？

众所周知现在产于中国的野生动物越来越少了。野马 、高鼻羚羊、糜鹿等10余种动物已经完全绝迹，而大熊猫、长臂猴、老虎、野象、白鳍豚等十几种野生动物正面临灭绝的趋势！由于一小部分的人的无知，贪婪，愚昧，到处捕杀动物使得地球生态不平衡，造成了不可估量的损失！

自然界的变化和人类的人为活动也是有关系的，如战争、资源开发、人口增长及农村城市化等，造成了生存环境恶化，使得动物资源又一次遭到严重的破坏，濒危的野生动物日益减少。人们随意破坏生态平衡，大量捕杀动物，把捕到的猎物一一卖给饭店、宾馆、酒楼等，然后做成菜，再已高价卖给食客进行食用。饭店、宾馆、酒楼就为了钱杀死了这么多无辜的生命，满足某些人的嗜好。人们啊，醒醒吧！保护动物也就是保护我们自己。杜绝乱捕乱杀，让我们和动物生活在同一片蓝天下。

让我们从小做起，保护野生动物，关心野生动物，让更多人都能投到保护野生动物的行动中来。

我们人类生活在地球上，地球上有许多东西需要我们保护，但是我们却没有在意。

We live on the earth, the earth there are many things we need protection, but we didnt care.

有些人不珍惜地球赐予我们的一切，例如人们乱砍乱伐，大量使用一次性筷子和乱扔塑料袋，制造白色垃圾等已经给大自然带来了许多环境问题，严重影响了我们的生活。还有大气污染，酸雨和臭氧层等带来的危害都是大自然给人类带来的灾害，人们乱砍乱伐，乱扔塑料袋和使用一次性筷子等，这些就是人们不尊重大自然而造成的，没有自然，便没有人类。这是世界一大朴素的真理，人们只会一味的抢夺自然，征服自然，只会破坏生态系统，咎由自取，使人类濒于困境。切记，保护环境就等于保护我们自己生存的环境。

Some people do not cherish the earth gives us all, for example, people cut down many trees, the extensive use of disposable chopsticks and throw plastic bags, producing white garbage has to nature brought many environmental problems, a serious impact on our lives.
