中学生英语演讲稿保护大自然2篇 作文怎么写（精选20篇）

以前的地球非常美丽富饶，有湛洁如蓝的天空，有绿草如茵的草地，还有清澈透明的河水，可现在的地球与以前截然不同，天空被浓烟笼罩，草地变成了沙漠，就连河水也变得浑浊不清。这都是由于现在人口素质不高。对生态系统缺乏认识，不了解自然规律，导致近年来全球的自然环境和生态平衡被严重破坏，现在全球每年有600万公顷的土地沦为沙漠，2000万公顷的森林在消失，平均1小时就有一种动物在灭绝，由于臭氧层被破坏，温室效应在加剧，使地球气温不断升高，南极冰冠开始融化，海洋平面将不断升高，世界上许多沿海城市、岛屿和大量土地，将被海水吞没。

此刻，就在我眼前出现了，显现蓬勃生机的绿色，那是一道亮丽的风景，在街上一排排绿色的大树，小溪在歌唱，小鸟在欢叫，这才是属于我们的家园，拥有蓝天、白云、森林。虽然，这一切都是梦，但是我相信，只要我们肯从身边的小事做起，只要我们有着坚定不移的信念就一定会成功，一定会再把地球变成以前的容貌。

让我们一起大手拉小手去创造一个新的地球吧。让地球变回鸟语花香的世界，让浑浊的小溪变得清澈透明，让土地上又长满绿茵茵的草，让地球妈妈变得更加美丽!

The survival of the earth is our home, its like mother, provide us with the resources and conditions of survival. We are the master of the earth, we should like to yourself to protect it.

Who wouldnt want to make their homes more beautiful, more beautiful? However, with the development of science and technology, more and more living garbage all sorts of multifarious, including most waste will cause environmental pollution. For example we commonly used battery, if you dont properly handle after use, it will cause a great environmental pollution. According to research, section button battery waste 600000 litres of water undrinkable. If each throw away a battery, then then, water, and will become a luxury.

So, in order to protect the environment, please put garbage sorting.

On June 1, 2008 in our country implements the "plastic limit order", the practice, to make our country save thirty-seven million barrels of oil a year. Plastic bags, this kind of thing for ordinary family ordinary but again, but you know, plastic bags is one of the main factors pollute the environment. Plastic bags with oil as raw material, not only consumes a large amount of resources, but also need 500 years to be natural decomposition.

So, in order to protect the environment, use less plastic bags, please.

As the owner of the society, to improve the earths environment, it is our duty-bound responsibility and obligation. If the world environmental protection, environmental protection, everyday everyone can create a new, beautiful world!

地球是我们赖以生存的家园，它就像母亲一样，为我们提供着生存的资源和条件。我们是地球的主人，我们要像善待自己一样去保护它。

谁不想让自己的家园变得更美好，更漂亮?然而，随着科学技术的发展，各种五花八门的生活垃圾越来越多，其中大多数垃圾都是会造成环境污染的。比如说我们常用的电池，如果用完后不进行适当的处理，那么将会造成极大的环境污染。据研究，一节废的纽扣电池能使60万升的水不能饮用。如果每人丢弃一颗废电池，那么到了那时，水，将成为奢侈品。

所以，为了保护环境，请将垃圾分类。

我国于2008年6月1日起实行“限塑令”，这一做法，使我国每年节省三千七百万桶石油。塑料袋，这种东西对于普通家庭来说再普通不过了，可是你知道吗，塑料袋却是污染环境的一大因素。塑料袋以石油为原料，不仅消耗了大量资源，而且还需要500年的时间才能被自然分解。

所以，为了保护环境，请减少使用塑料袋。

作为社会的主人，改善地球环境，是我们义不容辞的责任和义务。如果世界人人环保、天天环保，就可以创造一个崭新、美丽的世界!

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.

【参考译文】

许多野生动物正面临灭绝的危险，因为它们生活的环境已经发生了巨大的变化。例如，随着城市的发展，杀虫剂的使用和严重的污染，他们的生活区域变得越来越狭小。许多野生动物现在面临食物危机。同时，人类为了获取皮毛、皮肤、角、牙和肉而捕杀物种。

为了保护我们的生态资源，人们应该意识到任何物种的损失至少是知识的源泉和自然美的源泉。因此，本应采取以下措施：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物，保护区。

只有人类采取一些激烈的措施，野生动物才能被保存下来。

Everybody is responsible for protecting the environment, but in real life, often someone will not comply with this important environment, they often littering, spitting, quality and poor people will still defecate indiscriminately. However, we dont young pioneers in this way, we want to put an end to these bad habits, and destroy them all.

Now, in a lot of greening the ground will have some clues in the form of brand like this: "it is forbidden to practice (on) on the lawn", but these clues than those rich appeal, and impressive clues is a little stiff, rich taste, and can move the clues, like: "dont step on me, Im afraid of pain!" , "in addition to what also dont take away the memory, dont leave nothing but footprints!" "The grass there is life, the first step for green". They has distinguishing feature very much, also very attractive; Resistance is euphemistic and person aftertaste.

I often see on television, many public service ads are saying: everyone as long as we open a window, the world will be more bright.

Today is the Shanghai environmental clean-up day a day a month, two dozen of Shanghai government cadres to work together to protect our environment; The edge of the road, volunteers in picking up trash, pick up a cigarette first, visible from Shanghai how love Labour, love how clean and how love and health!

I sincerely hope that our shaoxing people also want to so love labor! Let us together for the sake of the environment, to act together!

保护环境人人有责，但是在现实生活中，却往往有人会不遵守这条重要的环境，他们经常会乱扔垃圾、随地吐痰，素质再差一点儿的人还会随地大小便。可是，我们少先队员不会这样，我们要杜绝这些坏习惯，把他们全都消灭掉。

现在，在许许多多的绿化地上都会插有这样形式的一些提示语牌子：“严禁践(踩)踏草坪”，只不过这些提示语比起那些富有情趣，又能打动人的提示语比较生硬一点儿，那些富有情趣的，又能打动人的提示语，就像：“别踩我，我怕疼!”、“ 除了记忆什么也别带走，除了脚印什么也别留下!” “小草有生命，足下多留‘青’”。它们就很有特色，也很吸引人;既委婉含蓄，又耐人回味。

我常常在电视上看到，许许多多的公益广告都在说：只要我们每个人都打开一扇窗，世界将会变得更加明亮。

今天，是上海每月一日的环境清洁日，上海二十多名机关干部们携手保护环境;马路边上，志愿者们在捡垃圾，捡香烟头等，可见上海人有多么热爱劳动，有多么爱清洁，多么爱卫生啊!

我真心地希望，我们绍兴县的人也要那么地热爱劳动啊!让我们一起为了环境而努力，一起去付出行动吧!

Ladies and Gentlemen , Good afternoon! I’m very glad to stand here and give you a short speech. today my topic is “youth”. I hope you will like it , and found the importance in your youth so that more cherish it.

First I want to ask you some questions:

1、 Do you know what is youth?

2、 How do you master your youth?

绿色多么宝贵啊！它是生命 ，无数片绿色的叶子给我们制造了氧气；它是希望，绿色代表了生机，它是大自然的本色。

在非常久以前，有非常多参天大树，一棵棵大树组成了茂密的森林，森林下有无数的鲜花、小草、蘑菇、野果，那里生活着无数的小动物。森林旁有一望无际的农田与清澈的小溪，人们在田间劳动时累了就停在大树下休息一会儿，风吹过来树叶沙沙地响，小鸟在头顶上叽叽喳喳地唱歌，小松鼠、小兔子在旁边欢快地跳舞……农民伯伯看着、听着、笑着高兴地合不拢嘴。

城市里人们都提着菜篮子买水灵灵的蔬菜，人们舒心的生活着，上下班步行或骑自行车，城市里到处是树木与花草。后来高压线、电话线、网线等等像蜘蛛网一样架过来，一个又一个工厂占用了大量的土地，一座座高楼拔地而起，原来大片大片的森林和农田消失了，于是美好的乡村和城市没有了，美丽的大自然在消亡，小动物、小鸟失去了家园，鲜花、小草越来越少了，环境变得越来越坏，这里暴雨冲毁了田野与村庄，那边干旱使庄稼全部汗死，一到春天还刮沙尘暴，天空灰蒙蒙的。害虫多了，到处都喷农药。城市里工厂冒着浓烟，排放着污水，汽车多得排起长龙……地球难受的流泪。

我们只有一个地球妈妈，我们该醒悟了，让我们携起手来共同保护环境吧。

亲爱的同学们：

你们好！

我是安阳实验小学的一名小学生，我希望你们能在百忙中抽出一点时间看一下我的建议书。

我们的瑞安是一个物产丰富、风景秀丽的好地方。周边的风景名胜数不胜数。万松山、隆山山上松杉葱郁，山脚鲜花竞相开放，一派生机勃勃的景象。

可是，你们是否有注意身边的一些恶习：洗好手，水龙头还在哗啦啦的流着，而用水人却不知所踪；房间里开着电灯、电视，里面却空无一人；学校教室里的垃圾桶，里面装的不是垃圾而是一些都还可以用的文具，仅用了几页的笔记本、才用了一半的铅笔，橡皮……数不胜数，殊不知现在的水电资源紧缺，贫困山区的孩子们连书都读不起，他们没有教室、书本、铅笔、纸笔……亲爱的同学们，你们是否碰到过类似的现象？你们是否想过大自然的资源是有限的，这些看似生活中的小事，会给人们带来多大的后果？

现在，地球上的森林面积已经减少了一半，就看近几年森林的面积还在大幅度减少。从1990年的40亿平方千米的森林面积到2001年的36亿平方千米，这是一个多么惊人的数据。另外据一则报道：虽然覆盖地球面积的72%是水，但是淡水还不到0。5%，而且70%的淡水都在南极、格陵兰的冰层之中，其余多为土壤水分或深层地下水，不能被人类利用。地球上只有不到1%的淡水，如果再继续浪费我们的水资源，地球上的最后一滴水将是我们自己的眼泪。

亲爱的同学们，珍惜自然资源，要从我做起，从小做起。因此，我要提出以下几点建议：

1、要植树造林，爱护树木，保护森林。通过大力宣传，让植树造林的意识深入人心，增强人们对森林保护的意识，同时减少浪费纸张的现象，从另一角度看，减少纸张浪费也是保护森林的一项重要举措。一张纸我们可以拿来练铅笔字，铅笔字练完了还能练中性笔，中性笔练完了还能练毛笔字……

2、节约用水，人人有责。在公共场地的洗手槽上方贴上标语，减少浪费水的现象。若有看见水龙头在不停流水，我们就要主动上去关掉闸门，为节约用水提供一份自己的力量。在家，还可以建议自己的的爸爸妈妈，淘米的水不要直接倒掉，我们可以拿这个淘米水洗菜，浇花，最后还能用于冲洗马桶呢。一举数得，既节约又环保，又何乐而不为呢？

为了我们的地球母亲能永远微笑，同学们，让我们立刻行动起来吧！保护自然资源从我做起。从身边做起。

今天，天气晴朗，阳光明睸，我和妈妈来到马峦山郊野公园。我们一边上山一边欣赏路边的美景。看，那小溪里的水多么清澈，像玻璃一样透明；那飞溅的瀑布多么壮观，真像从山上垂下来的一块白布。听，鸟儿在树林里叽叽喳喳地唱歌，多么的快乐！

我们登上山顶，继续向大梅沙进发。在路上我看见许多别墅，这些房子虽然很漂亮，但是我并不喜欢，因为它们的建造不知道砍伐了多少树木。

终于，我们走到了大梅沙海滨公园，在栈道上看一望无际的大海，走近可以看见一条条小鱼畅游在蔚蓝的大海中，大海真美啊！看得我都不舍得离开。

但是我总担心有一天鸟儿不再欢乐地歌唱，鱼儿不再欢快地畅游。因为我们正在日益破坏着它们的生存环境，工厂排放出来的污水污染了一片片海洋，过度砍伐树林逼着可爱的鸟儿离开它们的家园。每次想到这些场景都为小动物们感到担忧，我决定长大后要做一个自然保护主义者，向大家提倡是爱护环境，保护大自然。

让我们一起喊出我们的口号：保护自然，从我做起！

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. There are air pollution, acid rain and the ozone layer damage caused is human nature to bring disaster, people cut down many trees, throw plastic bags and disposable chopsticks, which is that people do not respect the nature and cause, no nature, no human beings. This is a big world, plain truth, people just blindly grab the nature, conquer nature, will only bring trouble to oneself, the destruction of the ecological system, humans dilemma. Remember, Protect environment is to protect our own living environment.

我们要保护这个脆弱的的地球，不要让茂密的森林，辽阔的草原和无边无际的海洋成为我们的回忆。

We want to protect this fragile earth, dont let the dense forests, vast grasslands and boundless ocean has become our memories.

现在起，我们应该保护环境，一起捍卫我们的家园。

Now, we should Protect environment, to defend our homeland.

每当妈妈说起他们小时候在河里摸虾、捉鱼，我就羡慕得不得了。硬拉着父母，让他们陪我去摸虾、捉鱼。可到河边的时候才知道，那里早已没了鱼虾的踪影，整个的是条‘抹茶河’。我才知道，原来大自然遭到了破坏，人们啊！请保护大自然！

如今，大自然遭到了破坏。小河不再清澈；鸟儿不再活泼；树木不再茂盛；花儿不再芬芳；草儿不再葱绿……这一切的一切，都是因为我们人类破坏大自然造成的。试想一下，假如没了植物、动物，那我们人类还能生存下去吗？当地球上的生物种类一个一个的灭绝，那么下一个会是人类吗？我们人类虽早已经脱离了大自然，但同时又离不开大自然。保护大自然，是我们每个地球公民的责任，可人类却与之背道而驰。不但不保护大自然，竟然还破坏大自然！

蚂蚁能预知下雨，老鼠能预知地震……这些动物的‘预知未来’的能力为什么我们人类没有呢？如果我们人类能像老鼠一样拥有预知地震的能力，那么在2008年的汶川大地震时，就不会有那么多的人员伤亡，就不会使得多少家庭妻离子散。那为什么我们人类就没有这种‘预知未来’的能力呢？一定是因为我们破坏大自然，导致地球母亲震怒，便剥夺了我们这方面的能力，就是为了让我们保护大自然！融入到大自然当中去。

我们人类应该学会与其他生物共同生活在地球上，应当与地球上的生物携手，一起保护大自然，保护我们的地球母亲，保护我们共同的家园！这样，我们才会更加幸福、美满！

改变一般说的是事物发生显著的差别。改变自己中学生英语作文又该怎么写的呢， 我们来看看。 改变自己中学生英语作文（一）

Things in the world are changing.

People are changing and every creature is changing. Changing is a neutral word. We can’t judge it is good or bad in general, because every coin has two sides. But sometimes we need to change, because it is good for us. Sometimes we will meet some difficult or uncomfortable situation. When we are not able to change it, we need to change ourselves. If both of us refuse to budge, the problem would not be solved. Sometimes we need to change our life attitude; sometimes we need to change our views of seeing things; sometimes we need to tolerant; sometimes we need to be strong.

Changing ourselves according to the specific situation is good for us. 改变自己中学生英语作文（三）

From my point of view, we should change ourselves when the situation can’t be changed any more. Difficulties hide in every corner of our life so we have to face them at times. But the problem is that we sometimes are not able to change the challenging situations at all as our abilities are limited. When it comes, we’d better change our attitude towards these difficulties. Only in this way can we get rid of the tough surroundings and be happy.

Something like that happened to me once. There was a time when I was laughed at by my classmates while I was walking. I was puzzled so I asked them why they laughed at me. One of them told me that the way I walked was very strange and funny. I was sad but I just couldn’t change the way I walked. And the situation of being laughed at by those people didn’t stop. Therefore, I changed my attitude towards the incident. I ignored those comments on me and walked as I used to. The comments soon disappeared and I was so glad to have succeeded in the quiet war.

So in my opinion, we should change ourselves first and then the situation can be changed at last. It is very difficult for us to change our surroundings but much easier to change ourselves. People around us will see our change, after which they may change their attitude toward us.

Protecting the environment and taking care of the earth is something we all should do.

Recently there are a lot of environment has been destroyed, around us there are many people in the destruction of the environment, cut down the trees, the birds were killed, flowers and plants have been burned, it is one thing for our warnings, the forests are disappear in every 375 square kilometers, the desert is evolving, flooded the countless individuals every beautiful homes, precious and there are ancient animals are killed, the panda has now been arrested, and so far only 1000 only, although there are a lot of people have built consciously protection station, but there are still some people for money by hook or by crook the killing of animals, birds no longer common, because being grabbed, trees less, because being cut, please protect them! If you go on like this, again, and the future of the animals we have learned in a book, according to people each with experts observation, day and night, a protective layer in the sky, the ozone hole, is because of the large hole lead to global warming, and the year before become very hot in the summer, many people died in the heat.

All this is because people open super sound emitted by aircraft emissions of waste gas and the car tail gas is left at the trial of toxic substances in the air into the results, if in so doing, the glaciers will melt, make the surface flat area, causing most of the land of the sea submerge.

If you dont stop cutting trees, when the trees were cut down light, desert will evolve, without the tree represents no oxygen, and the air was full of carbon dioxide, make the person cannot breathe, cause a person to cant live.

Please do not cut down trees, let the birds have a home, do not emit waste gas, let us live together in this beautiful earth!

It is important for everyone to keep good eyesight. But do you know how to protect your eyesight? （重要的是，每个人都保持良好的视力。但是你知道如何保护你的视力？）

If you obey the rules above, I think, you may prevent your eyesight from becoming short-sighted.（如果你遵守上述规则，我认为，你可能会阻止你的视力成为短视。）

[保护眼睛初二暑期英语作文

We often say that the earth is our homeland and human society comes from

nature. Therefore, I think our society is a part of nature. People should live

harmoniously with nature. All the materials we need to live with come from

nature, but we should also repay the nature, rather than blindly solicit. For

example, we should plant more trees and take actions to protect the environment.

In addition, we have to control population. Due to excessive population growth,

human beings require much more natural resources than before, which lead to

excessive pressure on nature. In order to long-term development, the population

growth must be controlled. We all come from nature which is our homeland, so we

must try best to protect it.

Boundless sea to look forward to, give people the beauty, give a person warm motherly love.

The sea is like a poem; it jumps; like a picture, rich in meaning; and like a symphony, vast and mighty...... It is like a mirror; sometimes calm, sometimes filled with rage, overwhelming, to sail the boat overturned. In my mind, the sea is blue world, is also the cradle of life. Pregnant with many free and small life. The sea is so mysterious, so charming!

Now the sea has changed. The sea is no longer clear, it becomes muddy and dirty. Washed up on the beach, left is no longer alive and kicking the fish shrimp, instead of the piles of rubbish, but also mixed with a lot of dead fish shrimp, stinking. Why is that? Its all because of us. When people admire the beauty of the seaside, they throw the foul rubbish into the sea. There are also people living on the beach, the toilet drain pipe to the bottom of the sea. Whats worse is that the factory waste water flows into the sea in large stocks, and the sea is dyed in a strange color. Led to the birth of a lot of lack of brains, low IQ infants, our next generation - bright eyes [voice tender], the face of the next generation of red, will never see the beautiful blue sea.

Someone once did an experiment. He compared a basin of water to the ocean, and dropped a drop of ink into the sea. Immediately, the ink slowly spread out, became shallow and disappeared. The sea water was almost as clean as ever. If the ink kept dropping, the color of the sea would be deeper and darker, and eventually it would become a basin of black water. 6 billion people on the earth produce large quantities of living waste water and industrial pollution every day. Like ink, it has been injected into the clear sea water. It has become a polluted lake.

To the health of our human beings, to see the beautiful blue sea for our children and grandchildren. Let us act now, love the ocean as much as we love life, and love the common blue home of mankind.

Saving Water

The world is not only hungry,but also thirsty for water. This may seem strange to you, since nearly 75 % of the earths surface is covered with water. But about 97% of this huge amount is sea water, or salt water. Man can only drink and use the other 3% -- the fresh water that comes from rivers, lakes,underground, and other sources. And we cannot even use all of that, because some of it is in the form of icebergs and glaciers. Even worse, some of it has been polluted.

However, as things stand today, this small amount of fresh water, which is constantly being replaced by rainfall, is still enough for us. But our need for water is increasing rapidly-- almost day by day. Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on. A limited water supply would have a bad effect on agriculture and industry. Let me give you just one small exampie of how necessary water is to industry. Did you know that to produce a single ton of steel, it takes about 91, 000 liters of water?

We all have to learn how to stop wasting our precious water. One of the first steps we should take is to develop ways of reusing it. Experiments have already been done in this field, but only on a small scale. For us, the systems are as important as the spacecraft.

节约用水

我们的世界不仅饥饿，而且因为缺水而干渴。对你来说这可能似乎奇怪：因为我们的地球表面75%由水覆盖着。但是，这巨大的数量中97%是海水、或咸水。只有剩下3%

的来自河流、湖泊、地下，和其他来源的淡水供人们饮用、使用。即使如此，这3%的水源我们也不能够完全使用，因为有些淡水是以冰山或冰河的形式存在。更糟糕的是，一些水源已遭受了污染。

然而，尽管按现状看来，这些少量的淡水即使时常转化成雨水的形式，对我们来说，也仍然够用。可是我们对水的需求却日益迅速增长。我们只有现在采取措施解决这一问

题才能避免未来世界范围内的严重水资源缺乏。限量供水会对农业和工业产生不良的影响。我们举个小小的事例就能证明水对工业的必要性。每生产一吨钢材就要消耗91，000升水，你知道吗?

我们必须杜绝对宝贵水资源的浪费。我们应该采取的第一步就是要发展水再利用的方法。该领域的实验已在进行，但是仅是小规模地进行。水资源再利用系统的重要性

对我们而言，与空间站不相上下。

Contribute to nature reserves and other wilderness areas.Habitat preservation is one of the best ways to help protect animals.You can donate money or volunteer your time helping the nature reserve preserve habitat.

Buy environmentally friendly goods.Choose non-toxic cleaners and lawn care items that wont pollute streams,rivers or oceans.Avoid any products that have been made from threatened or animals.Buy foods and goods that are made from materials that do not harm animals or their habitat.For example,look for organic chocolate,coffee or cotton clothing that is grown without cutting down rainforests or destroying habitat.

Create or restore habitat for animals.You can volunteer to help with projects worldwide designed to reestablish habitat.In your own backyard,plant a butterfly garden,use native plants and trees and let "wild" areas grow to provide habitat and food.

Join a local,national or global conservation organization.Some organizations focus on one particular animal while others focus on broad efforts for all species.You can "adopt" an animal through these organizations,which makes a great gift idea as well.

促进自然保护区和其他荒野地区。栖息地保护的最好方法之一是帮助保护动物。你可以捐款或志愿时间帮助自然保护区保护栖息地。

购买环保商品。选择无毒清洁剂和草坪护理项目,不会污染河流,河流或海洋。避免任何威胁或动物制成的产品。购买食品和产品,是由材料,不伤害动物或它们的栖息地。例如,寻找有机巧克力、咖啡或棉衣服,没有砍伐热带雨林生长或破坏栖息地。

创建或恢复栖息地的动物。你可以志愿帮助全球项目旨在重建的栖息地。在自己的后院,工厂一只蝴蝶花园,使用原生植物和树木,让“野生”地区生长提供栖息地和食物。

加入一个地方、国家或国际保护组织。一些组织专注于一个特定的动物而其他人关注广泛的努力为所有物种。你可以通过这些组织“采用”动物,使一个伟大的礼物的想法。

When I was very small, I lived in my hometown. My grandparents raised two

dogs, and I liked them very much. I watched them grow up from the little animals

to the big dogs. Every time when I leaved home for school, they would follow me

for some distance. When I walked a little far away, they would turn home. When I

went home after school, they would wait for me in the door and swayed their

tails. I knew they were welcoming me home. They were like my family members and

I learned that animals are part of our nature. We should protect them. We can

create a harmonious society.

导语：我们要从我做起爱护环境，保护我们这个赖以生存的家园，做一个保护环境的卫士。下面是yuwenmi小编为大家整理的英语作文，欢迎阅读与借鉴，谢谢!

我为周围环境的恶化而感到心痛，我想：作为未来接班人的青少年，如果不了解人类环境的构成和环境问题的严重性，无视有关环境保护的法律法规，不去增强环境保护意识，自觉履行保护环境的义务的话，我们的生命将毁在自己的手中，老天将对我们作出严厉的惩罚。为此我下定决心要从我做起爱护环境，保护我们这个赖以生存的家园，做一个保护环境的卫士。

With the improvement of peoples living standard, people more and more do not take the protection of the environment, throw rubbish everywhere and spit everywhere.

Whenever I see garbage on the ground, I will be deeply touched, protect the environment, starts from me. Take the a small river near my house, for instance, in the past, the water in the river is very clear, like a bright mirror, can see clearly the many stone in the river; You can see fish free in swimming in the river. There are often many children playing, playing in the river water; The adults in the river to wash the dishes, washing clothes. Gradually, people then throw the garbage into the river, sewage discharge into the river, make the river as well as smelly and dirty, can no longer on the bottom, into a murky waters of the bin. Serious environmental pollution, serious harm peoples health. Yes, only set up the idea of protecting the environment, have a better tomorrow.

On Sunday, I find to my good friend small good, each with a plastic bag, pick up the trash in the river one by one to light, our hands are full of bags, is really "to eat"! Even if we pick up the trash in the river, but you cant stop the garbage in the river, get off there will be, how to do? The most critical or arouse peoples environmental consciousness, we took a plank on the plate is greatly write: please protect the environment, starts from me. We put it in the river, in a prominent place in the task is complete, we are pleased to go home.

In order to protect our own home, in order to protect our own life, for the sake of our own future, in order to our beautiful environment, make the sky bluer, the water cleaner, let mother earth more lovely and more vibrant, let us open hands, a love, out of a force, creating a green environment.

随着人们生活水平的提高，人们越来越不重视保护环境，随地扔垃圾，随地吐痰。

每当我看到地上的垃圾，我就会感慨万千，保护环境，从我做起。就拿我家附近的一条小河来说吧，以前，河里的水十分清澈，像一块明亮的大镜子，可以清清楚楚地看到河底的许多石头;可以看到小鱼在河里自由自在在游来游去。经常有许多小朋友在河里嬉戏、玩水;大人们在河里洗菜，洗衣服。渐渐的，人们于是把垃圾扔到河里，污水排放到河里，使河水变得又臭又脏，再也不能清澈见底，变成了浑浊不清的垃圾箱。严重污染环境，严重危害了人们的身体健康。对，只有树立保护环境的观念，才有美好的明天。

星期天，我找来我的好朋友小好，每人拿一个塑料袋，把河边的垃圾一一捡光了，我们手里都是满满的一塑料袋，真是“满载而归”啊!即使我们把河边的垃圾捡光了，但是河里的垃圾是阻止不了，捞掉了还会有，怎么办好呢?最关键的还是唤起人们的环保意识，我们找来一块木板在板上大大地写上：请保护环境，从我做起。我们把它放在河边最显眼的地方，任务完成，我们高兴地回家了。

为了保护我们自己的家园，为了保护我们自己的生命，为了我们自己的将来，为了我们美好的环境，让蓝天更蓝，让清水更清，让地球妈妈更可爱，更生机勃勃，让我们张开小手，献一份爱，出一份力，共创绿色的环境。
