有关环境变化的英语作文【最新20篇】

我的家乡以前是一个山清水秀，鸟语花香的城市，可现在却......唉!

现在人们的环保意识太差了，乱砍树木。山上光秃秃的，害得小鸟无家可归。汽车排出来的尾气和工厂里排出来的废气，浓烟滚滚，天空也常常变得灰蒙蒙的。

还有人乱丢果皮纸屑，走在街上到处见到垃圾，甚至原来青青的小草，也被人们弄的灰色的了。我多么希望我的家乡能够变回原来的面貌啊!

晚上，我做了一个梦，梦见了我的家乡回到了以前那样，小鸟在树上"叽叽喳喳"地叫着，我正想着要仔细地看一下时，"咣"的一声，原来我碰到床头了家乡的环境(小学三年级习作)。

我相信，只要我们保护环境，从我做起、从大家做起，总有一天，我的家乡还会变成原来的样子的。

请珍惜绿树蓝天，那是我们的家园!

十年后每个垃圾桶都变得亮，街上的垃圾也没了，那十年脏脏的垃圾街上的垃圾都变了，变成了美丽的街道，变成了我们亮亮的垃圾桶，公园里、江滨公园里的健身器变美丽了，没有了一丁点儿被乱画过，可漂亮了。在去看看公园的日草坪，那绿绿的小草在快速的长高了，不像以前一样，小草上都是垃圾，小草都长不高了，可现在不一样，整个家乡都不一样了，相比起来现在在可美多了。

公园里的江水上没垃圾也有垃圾也没有了洗衣服的泡沫，水上只有一二棵水葫芦，每到夏天，有许多大人和老人或小孩在公园的大树下乘凉，看到大自然里的水葫芦，心情可愉快了。树上还有小鸟叽叽的叫着，仿佛在给人们唱着美丽动听的歌曲。

十年后可真美呀﹗要是我再加油，一定可以变得更美丽﹗

我扑向三月的乡村,披着柔情的春光,让略带甜意的和风从身边掠过.清澈的溪水、甜美的空气、芬芳的花朵让我浮想联翩.一阵婉转的鸟鸣,把我拉回了现实.看着眼前的美景,我不禁陷入了沉思：这儿什么时候变得这么美了?我还真没想到啊!

这不,我正惬意地躺在绿茵茵的草滩上闭眼沉思这个问题,不由得想起了这儿过去的样子.

从前,这里堆满建造房屋的砖头瓦块,以及一堆又一堆的沙子.风一吹,沙子随风卷起,漫天飞舞,行人不敢睁眼.更可恶的是,身上也粘上了沙子和尘土,拍打好一阵子也拍不净.这里还危险着呢!建造房子的吊车“咬”住一块块水泥板从行人头顶掠过,摇摇欲坠,小孩子都不敢走这里,就连大人看着也胆战心惊!这吊车要是“咬”松了,可就出大事了!还有,以前这里的溪水上面漂浮着垃圾,苍蝇在上面飞,看着都恶心,是名副其实的臭水沟.人们乱伐树木,小鸟没有了家,成了流浪儿……那时的环境真是不堪回首!

现在呢?这里焕然一新,变化可大了!简直就是天壤之别.树木随处可见,绿树成荫.小鸟有了安全的家,每天清晨站在枝头欢快地唱歌.婉转的歌声唤醒了太阳公公,唤醒了上班的工人,唤醒了耕种的农民,唤醒了上学的孩子.数不胜数的野花,点缀在这块绿毯之中,又平添了优雅之气.看,那儿还有野草莓呢!听,小溪唱着歌儿流向远方.还有,活蹦乱跳的小鱼在溪水里玩耍……我陶醉在这仙境般的地方,任由快乐在这美景里驰骋翱翔.

这意想不到的变化,让我欣喜若狂,感慨不已.珍惜自然,保护环境,美化家园,共营生命绿色,让这出乎意料的惊喜持续下去吧!

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.

N?o havia harmonia entre poderes e o equilíbrio constitucional （政宪平衡）do país estava em perigo com a luta entre o Parlamento e a Regência. O enfraquecimento das reservas em ouro preocupava o comércio e a diminui??o de nossa capacidade produtiva inquietava a todos.

As revolu??es do Rio Grande do Sul e do Pará amea?avam a integridade do Império. A nacionalidade mergulhava num ambiente de dúvida e de incerteza. As revoltas que se faziam para restaurar a normalidade acabavam por agravar os males, em círculo vicioso.

A sociedade debatia-se entre doutrinas mal assimiladas, sem encontrar interpreta??es certas, e radicalizava-se em partidos, fac??es e grupos. Sob o influxo das idéias da revolu??o que derrubara o Rei Carlos X da Fran?a, em 1830, e do federalismo americano, formavam-se grupos e aprofundavam-se diferen?as entre os homens. A fidelidade（忠诚） à Coroa, como nos dias da Independência, era um penhor da manuten??o da integridade nacional.

[关于国家环境的英语作文

社会发达了，谁不想有钱？但是，现在社会上有些人光想着挣钱，却把周围的环境给破坏了，我的家乡——阿勒泰，正是如此。

有一天，我来到桦林公园的后面的山上，长的茂盛的小草，有高有大的白桦树一棵棵挺立在山坡上，还有那又宽又长的河，清澈见底，一下子就可以看见小鱼在河里游来游去。

可是现在，山上的树木不断减少。河底的沙子被挖土机一个有一个大洞的，小草被人们践踏，草地上的草都没了……

君子爱财，取之有道。不要以破坏环境为成本，来制造财富。都醒醒吧，人们！我们要付出一切代价保护我们的家园吧！

Today the quality of our natural environment has become an important issue. The world population is rising so quickly that the world has become too

crowded. We are using up our natural resources and at the same time polluting our environment with dangerous chemicals. If we continue to do this, life on earth cannot survive.

Concerned people have made some progress in environmental protection. Governments of many countries have established laws to protect the air, forests and sea resources and to stop environmental pollution.

Still more measures should be taken to solve environmental problems. People should be further educated to recognize the importance of the problems, to use modern methods of birth control, to conserve(保存) our natural resources and recycle(再循环) our products. We are sure that we can have a better and cleaner place in the future.

今天,自然环境质量已成为一个重要议题。世界人口增长如此之快以至于世界已经变得太拥挤了。我们正在用尽自然资源,同时,用化学危险品污染环境。如果我们继续这样做,地球上的生命将无法继续存活。

Harmony with the environment is that we live in on Earth, who is a natural son, and not only to natural persons as the conqueror, as we all know, there is only one earth and the mountains on Earth, the animals. Plant human cells, if it damaged, destroyed nature organizations, to the eradication of mankind. Therefore, the environment must be linked with social ethics, character education and practice acts as an important elent of it. Everyone must fulfil its responsibilities and obligations to protect the environment.

【参考译文】

人与环境是和谐相处的,我们生存在地球上,人是自然之子,而不能仅把人看作自然的征服者,大家都知道,人类只有一个地球,地球上的山山水水、动物。植物是人类的细胞,如果我们把它损坏了,破坏了大自然的组织,等于消灭人类。因此,环境要与社会公德联系起来,与实践行为作为人格教育的一项重要内容来抓。每个人都要履行保护环境的责任和义务。

今天是星期六,妈妈说:"我们到奶奶家去吧."我一听,高兴得一蹦三尺高.奶奶家在乡下,那里可美了.

村子前有一条清澈见底的小溪.小溪里有一些可爱的鱼群在那里嬉戏、玩耍.有时,我还从小溪里捉几条小鱼来玩呢!小溪边还有几棵高大挺拔的柳树.柳树在微风的吹拂下,嫩绿色的"小辫子"飘起来,美丽极了!柳树下,一片小草坪像绿色的地毯.地毯上长着几朵小花,花的颜色真多,有红如火、白如雪、紫如茄……后面还有一片片竹林.那里是鸟雀的天堂、蝉虫的歌台.天空的空气清新甜润,还有小鸟呢!

可是现在,人们盖起了楼房、工厂房顶烟囱林立.人们随地乱扔垃圾,风一吹,垃圾腾空而起,在天空张牙舞爪.天上的小鸟一只也没有了.发出了难闻的气味.以前的花也不香了、枯萎了.小溪里的鱼都死了,水上还漂浮着小甲虫的尸体,可怕极了.人们把污水直排放到小溪,而且把垃圾扔进去了.

看了这样的情景,我希望家乡的人们赶快行动起来保护好周围的环境;多希望家乡高山常青,绿水常流……

Save the Wild Animals

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.

保护野生动物

许多野生动物正面临绝种的危险，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，野生动物的生活区域变得越来越狭小。许多野生动物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。

为了保护生态资源，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;严禁杀害某些稀有物种;应建立国家公园作为野生动植物保护区。

我们只有采取一些有力措施，才能保护野生动物。

环境污染是当今世界上最大的问题。请根据提示，用自己的话说说怎样保护我们的水资源。

(1) 生命离不开水资源 (2) 饮用水在减少 (3) 水污染严重(4) 应该保护和再利用水

We cant live without water, but now the water was polluted. It is the biggest problem. It influences our daily life. So we should find a way to solve this problem. Water is important resources. In our daily life, we often leave the tap on after cleaning hands. Sometimes we often drop litter in the river. So the water was polluted by us. I think we could use a bottle of water two or three times. We have to turn off the tap after cleaning hands.

Lets try to form a good habit and save things around us. Lets do it from now on!

Water is very important to us. We cant live without water. But the drinking water is less and less. Because we waste a lot of water in our daily life. And some of us often throw rubbish into the rivers. So the rivers are polluted seriously.

Its our duty to save water, we must do something to save water. For example, we shouldnt pour waste water into the rivers and we should pick up litter around us.

If we dont save water, the last drop of water will be our tear.

Fish cant live without water. Plants cant live without water. People cant live without water, either. As you can see, the water is very important to us. But now drinking water is less and less. The water was polluted seriously.

So we would act quickly in order to save the water, But what must we do now? I think we can plant trees, clean the banks of the river, water the plants by using used water. Turn off the shower while we are washing hair. And we shouldnt drop litter into the river and so on.

Its our duty to try our best to protect and save water. And dont forget that if we dont save water, the last drop of water will be our tear.；

If we dont save water, the last drop of water will be our tear. What a frightful announcement!

Water is very important for people, animals and plants. Water is needed to many things in daily life, like taking a shower, drinking, washing clothes, making meals and so on. We cant live without water. But now water has become less and less because people waste water and pollute water. If we continue to do things like this, we shall destroy ourselves. So we should take action to improve the environment quickly. We shouldnt throw rubbish into the rivers. We should pay attention to environmental protection. We can use less water when we wash something. In a word, we should save water.

Take action quickly, there will be hope!

Water is very important. Without water, there can be no life on earth. People and animals need water. We need it to drink, to clean ourselves and to cook. What we need is fresh water, but most of the water on earth is sea water. The drinking water is becoming less and less because water was polluted by people. What should we do? I think we should save water. For example, when we brush our teeth, we should turf off the tap. We shouldnt pollute the fresh water. If we dont save water, the last drop of water will be our tear. If we continue to pollute water, we will live in a thirsty world.

Pollution is becoming more and more serious all over the world. The factory eject the dirty water, as a result , the water has becoming polluted and many fish species are dying out. We cant live without water. The earth is our only home and we should make it comfortable for ourselves. We should save water in our daily life. For instance, turn off the shower while you are washing your hair. We should recycle water. Dont let our tear become the last drop of water!

The most serious problem in the world is pollution. Water is the source of life. We cant live without water. But now some of the drinking water has become polluted and is diminishing. Something must be done to stop the pollution. Its our duty to save water. We should stop factories from pouring waste water into the river. We should plant trees in order to keep soil. If we dont save water, the last drop of water will be our tear.

The most important question in the world is pollution, but we know water, like air is very important to living things because all animals and plants need water. We, like fish cant live without water. We need it to drink, cook, and clean ourselves. We need clean fresh water, but we are polluting the lakes and rivers. Our drinking water is becoming less and less. If we continue to do things like this, we shall destroy ourselves.

I think we should follow the rules. Dont throw food away. We try to make a good habit. I know its our duty to save water. So we should save water and protect eh environment.

Now water pollution is the most serious problem. We cant live without water. Water is life. So I think we should do something go save and protect water.

One: turn off the shower while you are washing your hair.

Two: we can use the water that has washed vegetables to water plants

Three: When you see someone is wasting water, come over and stop him.

Four: Dont pour the rubbish into the river.

Though these are small things to protect water, I still thin theyre important.

good environment can make people feel happy and fit . to improve the environment means to improve our life.

we should plant more trees and flowers around us . we shouldn’t cut them down . we should stop factories from pouring waste water into the river and waste gas into the air.

whenever we see litter on the ground , we should pick it up and throw it into dusbins. never spit in public. don’t draw on public walls. it’s our duty to protect the environment.

随着现代工业的发展和人口的不断增长，水的污染日趋严重。工业污水和生活污水中的有毒有害物质，经过多种途径污染着地面水和地下水，而农药和工业废气、废渣中的有害物质，经雨水的冲刷溶解，也污染了水源。少年儿童饮用了污水后，会引起急性或慢性中毒，以致影响身体发育。饮水中氟含量大时，会得氟骨症、牙齿松脱症。电镀废水中含有很多有毒物质，如未经处理就排入水中，它的危害性极大。饮用水被肠道致

病菌污染后，会引起霍乱、伤寒、肝炎等疾病的流行。

噪声对少年儿童的健康危害极大。生活在城市里，喇叭声、撞击声、轰鸣声、爆裂声、吵闹声以及电视机、收录机等家用电器发出的噪音都会影响孩子们的身体健康。噪音在当今世界上的很多国家，都已成为公害之首。噪音可以使人头痛、昏晕、智力衰退。受噪音影响的时间长了，还可能引起心血管系统的疾病，有时会使血压升高，甚至使人发疯。

据调查，在美国洛杉矶国际机场附近上小学的儿童，每天都听到喷气式飞机起飞和降落的噪音，因而普遍患有持续的高血压症。

我国的环境专家曾对居住在某铁路边的青少年进行过心脏和脑神经健康状况的检查，然后通过电子计算机进行分析，证明噪音会损伤心脏，噪音也会影响儿童的智力发育，吵闹区的儿童智力比安静区低20%，长期生活在铁路旁受噪音影响的青少年儿童健康的危害已经引起全社会的关注。

在城市的快速发展中，污染的越来越大。到处都是垃圾，对人有极大影响。

我想说：“大家只要同出一份力，人人尊守规则，只要多走一步，就不会这样。在城市里，有很多的环卫工人，他们那么辛苦，为我们能有一个好的环境，付出了许多，我们应该想想她们，想想她们为我们的做的一切，我们要体量她们，不要破坏她们的劳动成果。”

在暑假里，我在外面做了一些好事。例如：检垃圾、扫地等等。我也为人们做了事。想到这，我很开心。

一天，我在马路上。我正在捡垃圾，想到这么多的垃圾多终于捡完了，我很欣慰。这时，我正在高兴，突然，看一个阿姨从车上扔了一碗面下来。我气死了。我当时就说：“你怎么这样啊!我好不容易弄好的，就被你弄坏了。”她头都不回一下，只管自己走了。我叹到，这世上的人要都跟她一样，岂不糟蹋了这美好的世界。嘿!世间如此美妙，你却如此污染。嘿!

城市与水有着密不可分的关系，城市离不开水，人就更离不开。我宣告：世人要给后代留下一个美好的环境，请好好保护环境，我了自己，也为了炎黄子孙和后代。

我的家乡在芜湖市的一个小县城里。在最近的几年里，那儿发生了一些变化，而看到这些变化，使我感到十分的自豪，因为我的家乡变得发达了，家乡里的人变得勤劳，变得文明了。

以前，要转好几个大弯子才能到家，都把我的头给转晕了，可现在修了一条宽阔的大马路，使交通方便了许多，路也既好认，由省时;以前的路都是用石子铺成的，十分的简陋，一路上都能把人给颠死，而现在都是用柏油铺成的，十分地平稳;以前的人大多数都是以自行车为交通工具的，买不起那三轮车、货车……而现在的人们都十分勤劳，个个都认真、仔细地干活，努力挣钱，有许多许多人家都有了三轮车和货车;以前的人们出口成“脏”，可现在的人们文明多了，天天“谢谢”、“没关系”、“请”……文明用语挂在嘴边……

虽然我的家乡出现了许多新的面貌，可有一点却十分的不好，就是赌博。就拿我的爷爷说吧，他整天跑到外面去赌博，有时赌得连饭都不回来吃，他赌就赌吧，但他经常输钱，搞得后来拖了一屁股的债没还，还经常被姑爹他们骂，真是自讨苦吃。

我希望下一次回家乡时，又能看见一些新的面貌。

我来到了美丽小康河，被这里的景色迷住了。想想以前的小康河是一条臭的让人害怕的臭水沟，沟边上杂草丛生，沟底到处都是易拉罐、塑料袋、果皮、纸屑等生活垃圾，发出的腐烂臭味使经过这里的人们不得不掩鼻而过。

如今的小康河河水清澈见底，小鱼在河水里自由自在地嬉戏，好像世界上只有它们最快乐。河中的喷泉更是让人流连忘返。对面有一座石壁，上面画着许多画，石壁的上面还有一些形态各异的石头，远远望去石壁显的格外的壮观。

夜晚上的小康河景色更加美丽，河水缓缓地流动着，岸边的霓虹灯照射在水面上，河水立刻变的五光十色，真是美丽极了!不论是白天，还是夜晚人们依然喜欢这么美丽的小康河。

要不是市委，市政府，还有我们劳动人民的辛勤的劳动和智慧，我们怎么能看见这么美丽又壮观的小康河呀!

小康河是凤凰城中的一条和谐之河，是高密建设的一个精品的景观工程，从改造、规划到设计，处处体现着高密决策人的魄力与决心，处处体现着建设者的精巧和智慧

小康河从计划2至3年完工，到仅用11个月顺利完成，是效益与质量的榜样。小康河的建设为高密政府的决策提供了宝贵的经验。这是一个让民众认可而赢得民心的优良工程。小康河的建设为高密的城市拆迁、南湖公园的建设、文体中心的建设提供了样板。小康河的建设产生了高密的“小康河精神”。从政府到群众，在小康河综合改造建设的过程中，那种干事创业的雷厉风行的工作作风，那种真抓实干的工作干劲，那种攻坚破难的工作韧性，增添了小康河精神的内涵。所以说作为高密的小康河，不仅仅是简单的一条小河，而是高密精神的一种体现，一个很好的载体。小康河精神必将影响着高密人今后的决策、今后的创业。

小康河是一条文化之河。一个城市的建设不仅仅是钢筋混凝土、高楼大厦，一个城市的真正品位是它的文化内涵。我们想到北京就想到四合院，想到苏州就想到园林建筑成了文化的载体，建设改造小康河也是在做文化。我们的“三贤四宝”，我们的“高密八景”等蕴含其中，我们是在做高密自己的文化。小康河小康河是一条和谐之河。小康河竣工以后，成了我们高密人休闲、娱乐、商贸、文化交流的重要场所。是高密城市中心人气最旺的场所之一。是高密城市精神的写照，是高密城市品味的彰显，看高密必看小康河。小康河是政府与群众交流的平台，是政府与民众搭建的桥梁，康河之水流到了百姓的心田。小康河精神蕴涵在高密精神之中，为我们提炼高密精神打下基础。高密精神的表述应该考虑用“高密元素”来表达。例如：“凤凰城”、“大禹”、“三贤四宝”、“红高粱”、“小康河”等等政治、经济、人文的词语。应该有我们的地方、地域的个性特色。因为越是民族的，越是世界的。高密精神的提炼要体现于时俱进，要有历史的继承、还要有发展的指引。能够使我们想到我们的过去，还能够使我们展望到高密的未来。

必将留在我们高密人的记忆之中，因为小康河里流过我们高密人奋斗的汗水，小康河是我们高密城市变迁的历史见证。

小康河是我们中国人的骄傲，我们不应该在小康河上乱扔果皮、纸屑，而应该保护小康河，不让它伤心、难过，它最希望的是自己的身体健康。

让我们行动起来吧，保护小康河，保护我们的家园。

[小河环境变化的作文

我们面对的一个五彩缤纷的世界，这个世界日新月异，瞬息万变，当今的社会更是在不断发展，我们应该适应这个日新月异的社会，让我们去感受一下身边的变化吧！

现在，正值农忙时节，田野里一片丰收的景象。农民伯伯脸上漾出了丰收的喜悦。他们忙碌了一年，终于把这丰收的时刻盼来了，心里能不高兴吗？只见麦地中有一个小巨人似的东西在前进，一开始我以为这是自动的；仔细一看原来是有人在驾驭着它呢！通过了解，我知道了他可是农民伯伯的“好帮手”。

为什么这样说呢？记得当初没有它的时候，农民伯伯只能在太阳的炙热下一刀一刀的割，这给叫镰刀的工具好像在故意和他们作对，一点都不听话。农民伯伯们辛辛苦苦的工作着，不知工作了多少个日日夜夜，最后才能转变为想雪白的面粉。“我想他们真是太辛苦了！我真想帮帮他们呀！可是我又能帮他们做什么呢？现在，农民伯伯有了这么一个好帮手，真是太幸运！他们不用像以前那样劳累了，大约十分钟就能把事情全方面做好！小巨人可只是他们的好帮手啊！

21世纪是科技飞速发展的时代，即使我身处农村，却也能感受到迅猛发展的冲击！

未来的环境早晨，我走在上学的路上，听到一声声呼唤：“救救我啊!救命啊!” “是谁在喊救命？”我问道。“是我地球妈妈。”我说：“有什么事吗？”地球妈妈说：“你跟我到未来世界一下。” 就这样我来到了未来世界，本以为未来世界是一个很美很美的世界，可是······ 在这里看不见蓝蓝的天空，看不见白白的云朵，看不见美丽的花草树木。只能看见一层层乌云和垃圾，汽车排气管里吐出的黑烟，还有一阵阵沙尘暴。这里的人类用的都是一次性筷子，白色塑料袋。这里的环境太不好了！一点也不如现在的世界。谁都不愿意在那个世界吧！那就让我们一起保护我们的家园，我们不乱吐痰，不随手乱扔垃圾，不砍伐树木，做一个文明、爱护环境的好公民吧！

可看看现在的南京，是一个多么繁华、美丽的城市！如今的道路早已是一条条宽阔平整的柏油大道，道路两旁怒放的鲜花与高大的香樟点缀着大路。一排排高楼大厦都拔地而起，家家都开起了小汽车，人民群众的生活条件越来越好了。南京的夜晚，华灯初上，霓虹灯在不断闪烁着，疾驰的小轿车呼啸而去，南京的地标性建筑，紫峰大厦，此刻像一个伟大的巨人，高傲地俯瞰着这片土地。一旁星罗棋布的大楼，正散发出柔和的光线，无不在彰显着这个生我养我的城市之繁荣昌盛！

随着时间的前进，时代也不断进步，我看到的，不仅仅只是家乡的变化，更是我们祖国的变化，我中华民族的变化！

翻开中华民族的沉厚史册，从古至今，蜡黄的史页中折射出清晰的答案，从古至今，每一次的时代进步，都是我华夏儿女用汗水与智慧所取得的结晶！

我为家乡的新变化而欢欣鼓舞，我为祖国的成长，而骄傲！

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 bee 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。

过去，人们不必担心保护环境的问题。因为那时地球上人口稀少，自然资源似乎取之不尽。如今，一切都改变了。世界变得拥挤异常。我们正在耗尽我们的自然资源，有毒化学制品的使用也正污染着环境。如果我们继续这样下去，地球上的生命将不复存在。我们都明白如果从海里捕捉太多的鱼，海里就不会再有鱼了。可是，现代化的捕鱼技术使得捕鱼量越来越大。我们都明白如果砍伐太多的树木，森林就会消失。可是，我们仍旧使用强大的机械砍伐越来越多的树木。我们都明白如果河水被废弃物污染的话，我们仅有死路一条。可是废弃物仍然源源不断地进入河里。

We know that if the population continues to rise at the present rate， in a few years， there won＇t 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。

我们明白，人口继续照此刻这个速度增长的话，不出几年，就会发生食物短缺。我们该如何解决这些问题呢?如果我们多吃蔬菜，少吃肉类的话，我们就会有更多的食物。因为同样大小的土地如果种庄稼的话会比养殖动物多养活五倍多的人。如果我们学会再利用的话，自然资源就能持续更久。如果人们使用现代化的生育控制方法，世界人口就不会增长如此迅猛。

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

最终，如果我们能够教育人们都意识到这些问题的话，未来我们就会有一个更好、更洁净的星球。
