保护树木很重要英语作文精选20篇

森林是孕育人类的母亲，没有树木就没有森林。树木能保护土壤，树木能涵养水源，树木能调节气候，制造氧气……树木对人类的好处可大了，我们要保护树木。接下来，我为大家讲一个故事，希望大家能够 更好得保护我们的母亲：

李爷爷的生活条件一直不好，总想改善改善。一天，他四处走动，想着赚钱的法子，他来到了一块草地里，一棵棵大树挺拨地站在他面前。他眼前忽然一亮，对了，卖树！这真是一个好主意，他兴 奋地想着。他立刻到集市里买了一把斧子，准备明天就开工。

第二天到了，李爷爷拿着斧子来砍树，砍呀砍，半小时过去了，李爷爷还在砍树，他累得气喘吁吁，才砍了两棵树，他休息了一会儿，又拿起斧子继续砍树，就这样，日复一日，两个星期过去了， 这块草地上的树已被砍光了，李爷爷又在这块草地的边界设了一块木牌子，上面写着“出售圆木”几个大字；半年过去了，李爷爷的树木全卖完了，由于没有树木的阻挡，草坪上的草也枯死了，而且还 有大部分的沙尘暴向这里袭来。经过时间的消磨，这儿的沙子已经堆积起来了，形成一座小山。李爷爷的儿子没有工作，也想以卖树为生，可当他来到草坪上，正想砍树，可是他连一棵树也没有看着， 只看到了堆积如山的细沙，于是，他立了一块“出售细沙”的牌子，卖起了这儿的沙来……

这是一个令人发省的故事，有的人为了自己的利益，不惜一切代价砍伐树木。现在我国有些地区都因树木资源枯竭而沙漠化，污染了我们的环境，这些为了自己的利益的人难道不觉得可耻吗？

树木故有地球之肺之称，是因为树木大量地吸收二氧化碳，制造人类和其他生物所需的氧气，树木是氧气的制造场，是粉尘过滤器，树木还是天然蓄水库和天然空调，希望我们都来保护树木，不要 再滥砍滥伐了，树也是有生命的。让我们好好保护树木吧！让它们更好得造福于人类！

在以前有个美好的国度，简直就是人间仙境。

那里的花草树木也很好。树木密密麻麻的，你要是到树林里去一定会迷路的。那里的花也有很多，有兰花、杜鹃花等等。那里的草也有很多，到处都是，草丛里有许多虫子，仿佛是在玩捉迷藏呢！你要是踩到草丛里，准会被虫子咬得哇哇大叫。

现在的河里有许多垃圾，有泡漠，塑料袋、易拉罐、菜叶等生活垃圾。

现在的花草树木很少了。有的已经被人们踩成了一条路，有的甚至被人们砍下，制造成了一栋栋房子、各式各样的工具、应有尽有的家具。

破坏后果是很严重的。听不到鸟儿歌唱，看不到百花盛开，不再有河流存在，也没有各种动物，整个世界就是一片荒无人烟的沙漠。可以肯定地说：如果我们人类不对自己的生存环境进行肖邮票有效的保护，甚至还恣意破坏，那么，迟早要受到大自然的惩罚。

我希望每个人都能保护树林、保护树木，让都市的生活添一分绿色！

a country maid was walking along with a can of milk upon her head,when she fell into the following train of reflections."the money for which i shall sell this milk will enable me to increase my stock of eggs to three hundred,these eggs,allowing for what may prove addle,and what may be destroyed by vermin,will produce at least two hundred and fifty chickens.the chickens will be fit to carry to market just at the time when poultry is always dear;so that by the new year i cannot fail of having money enough to purchase a new gown.green-let me consider-yes,green becomes my complexion best .and green it shall be, in this dress i will go to the fair,where all young fellows will strive to have me for a parter;but no-i shall refuse every one of them,and with a disdainful toss turn from them."

transported with this idea,she could not forbear acting with her head the thought that passed in her mind,when down came the can of milk!and all her imaginary happiness vanished in a moment.

Protecting birds is part of our jobs of protecting our own living environment. Imagine you live in a place with green trees and colourful flowers. The little birds are flying around and singing happily. Its such a wonderful place to live. On the contrary, if we damaged the nature, chopped all the trees and kill all birds, we will live in a desert where has no living creatures. What a boring live would be! Therefore, we should protect birds as we protect our childern and ourselves future.

一年一度的世界防止荒漠化和干旱即将临近，我们开始纷纷保护树林和树木。一大半的人认为只有在植树节才要保护树林和树木，我的观点却恰恰相反，我们不能只在植树节保护树林和树木，应该无时不刻的保护着树林和树木。

几亿年前，地球归动物所拥有的时候植物繁茂，到处生机勃勃，充满了绿色，但是，智商远远高出其他动物的人类出现后，植物像被施了魔法一样的急剧减少。那是因为，人类为了建造房屋，砍伐树木所造成的。有的是因为商业需要，大批大批的砍伐树林留出空地，用来建造大楼。正因为许多人擅自砍伐树林和树木，所以大自然被破坏。

砍伐树木的坏处很多。大家都知道树木可以循环二氧化碳，如果大量砍伐树木，树木的数量就会急剧减少，我们呼出的二氧化碳无法得到循环。茂密的树木可以阻挡沙尘暴，前两年北京遭遇沙尘暴，整个城市被沙子所笼罩这也是因为缺少树木的保护所造成的。

大家都知道中原两湾城吧!以前，那里破烂不堪，那些平房的瓦是东一个洞，西一个洞，门是一块木板做的，街道里堆满了垃圾，脏及了。现在中原两湾城建起了公寓、大厦，河水清澈见底，河边杨柳随着微风轻轻摆动,这就是人们意识到了尊重自然，保护环境的重要性。

我希望每个人都能保护树林、保护树木，让都市的生活添一分绿色!

今天天是3月12日植树节，我在家拿了一把铁锹，提了一桶水去植树了，我来到公园的的小树林边，这时，我发现有两个小同学正在打架，我忙走到他们面前了解情况。

“你们怎能么了?”他们才静下来。一听事情是这样的：一个叫金希的说：“我今天早晨带着足球来玩我看见一棵大树，这可以成为我天然的标耙，我就踢了起来。

可这小子来了以后就跟我抢树，常续说：“我看见树上有个横着的树枝，正好可以拿它当秋千玩，是我先看见的。听完之后，我对他们说：你们都错了，你们应该好好对待树才是。

树有好多的好处：可以净化空气，可以美化环境，还可以防止水土流失，避免沙尘暴，这是一石四鸟啊他们这才知道错了，为了弥补错误我就让他们和我一起植树。还立了个牌子。“爱护树木，人人有责。”

人类和树木都是大自然的一部分，种树给人类许多的好处，如果哪一天没有了树木，那么就可能是人类的末日了，所以大家一定要爱护树木。

提示词；1.save water, the source of life , protect drinking water, stop polluting, make full use of it；2.save electricity, crucial, turn off, other electric machines；3. save forests, useful ,stop cutting down；4.recycle useful rubbish, save resources

参考作文：

Although the world develops much faster and better, the resources on the earth get fewer and fewer.In order to protect them,something must be done.

Save water. Water is the source of life. No water, no life. So its very important for us to do so.Not only should we protect drinking water and stop polluting it, but also make full use of it.

Save electricity. It is crucial. We cant imagine what the life will be like without it.Everyone should do his best to save electricity. Dont forget to turn off lights or other electric machines when we finish working.

Save forests. They are useful .Please stop cutting them down and use recycled paper instead. Make our world a green one to live in.

Recycle useful rubbish. Plenty of rubbish can be recycled like cans,paper, bottles, and so on. We can save resources in this way.

What kind of environment should be? Ought to be beautiful, but also should

be to let people feast for the eyes, but now all of you take a look at the

environment, beautiful? Let people feast for the eyes? The answer is no.

So what should we do? Today, Ill give you some advice to protect the

environment, the content is as follows:

We live earth is deteriorating rapidly, did we have to pay attention to

their own living environment cause harm to nature, you must not throw sundry,

especially those serious pollution of garbage, waste batteries, for example,

because the section waste batteries contain heavy metals, if flow to clean the

water, it is very much pollution, then try to save trees made items such as

paper, pencils, because waste these things is the destruction of the forest.

Also try to use less disposable lunch box, chopsticks and plastic bags and other

items, so as to avoid unnecessary waste and reduce waste.

There are some tips: walking to closing the master switch, in order to

avoid electrical appliances overheating explosion, a waste of money and waste of

electricity, save water, to shut the tap when brushing your teeth, wash dish

water to rice, rice water to water the flowers, wash water can sweep the floor,

so we can reduce some waste. 12 dont hunt wild animals, animal protection is

absolutely cant kill, but dont kill the common animals such as frogs, because

frogs eat 15000 bugs for us, and most are pests. Some people often dont think

that is, the stubborn still, so we should try to eat less wild animals, lead to

wild animals, the drop in sales no longer killing of wild animals.

Our forest is called oxygen plant, so to take good care of flowers and

plants, not to destroy the city greening, and actively participate in. But also

to cut down trees less, dont waste wood items, because waste these things is to

destroy the forest, so be used sparingly, to protect the forests of less and

less.

Use energy saving lamps to replace the ordinary light bulb, although some

expensive but can use less electricity. I appeal to you: in our daily actions to

protect earths environment, let our children and grandchildren live in a

beautiful environment!

Now in the era of rapid development, drive a car at work, waste water and electricity, such as timber has been used to it. And is this a series of moves, people are destroying the scar to the earth, environmental protection has been forgotten by the people.

I saw advertised in the country for a year only food waste is equivalent to pour out the ration of two hundred million people a year, this is an astounding number, thus we can see the waste is huge. Moreover, Chinas waste is not a little, we do not pay attention to the automobile exhaust, the harm of battery is buried in the soil... Thus China has become a "waste of power.

How can I be eco-friendly? This is a simple and complex problems. I think "starts from the minor matter" is the answer to this question, never throw rubbish casually, from shopping after all bring their own shopping bag, start from go out by bus more, since to use less disposable chopsticks, lunch box... Environmental protection needs to be done? Eat less animals, with environmental protection batteries, use less air conditioning, water reuse, conveniently turn off the faucet, will waste paper recycling and so on many ways, as long as it contributes to the environmental protection way, is environmentally friendly.

Environmental how many, how much your moral, environmental protection, how much you love how many, how many green, you how many character. From now on will do a green, understand environmental protection, people to protect the environment! Make the earth a better place, let the life become more beautiful, make people more beautiful!

Let the green, everywhere!

在时代飞速发展的现在，上班时开汽车，浪费水电、木材等已经习以为常了。而就是人们的这一系列举动，正在摧毁着伤痕累累的地球，环保已被人们遗忘在脑后。

我在广告上看见全国一年仅餐饮浪费就相当于倒掉了两亿人一年的口粮，这是一个惊人的数字，由此可以看出我们的浪费是巨大的。而且，中国的浪费不是一点点，我们从不注意汽车排放的尾气、电池埋在土里的危害……由此中国成了一个“浪费大国”。

怎么才能做到环保?这是一个有简单又复杂的问题。我觉得“从小事做起”才是这道题的答案，从不把垃圾随便一扔做起，从以后购物都自带购物袋做起，从出门多乘公交车做起，从少用一次性筷子、餐盒起……环保需要做什么?少吃动物、用环保电池、少用空调、把水重复使用、随手关水龙头，将废纸再次利用等许许多多的方式，只要对环境保护有贡献的方式，都算是环保。

环保有多少，你的道德就有多少，环保有多少，你的爱心就有多少，环保有多少，你的人品就有多少。从现在起做一个会环保，懂环保，做环保的人吧!让地球变得更美好，让生活变得更美好，让人们变得更美好!

让环保，无处不在!

ver 70% of the Earth’s surface is water; water is obviously the most precious natural resource that exists on our planet. Without water, life on Earth would be non-existent. Water is the lifeblood of the environment, essential to the survival of all living things-plants, animals, and human. Although we recognize this fact, we disregard it by polluting our rivers, lakes, and streams. Afterward, we are slowly but surely harming our planet to the point where organisms are dying at a very alarming rate, and our drinking water has become greatly affected. In order to fight against water pollution, we must understand the problems and become part of the solution; we also need to do everything possible to maintain its quality for today and the future.The government alone cannot solve the entire problem; it’s up to us when it comes to the problems we face with our water. In your home, correctly dispose dangerous household products. Keep paints, used oil, cleaning solvents, pool chemicals, and other dangerous household chemicals out of drains, sinks, and toilets because many of these products contain harmful substances. In your yard, recycle used motor oil. Avoid pouring waste oil and resist the temptation to dump wastes onto the ground.These are just a few of the many ways in which we, as human have the ability to combat water pollution. If these measures are not taken and water pollution continues, life on Earth will suffer severely.

Let’s Do Something to Save Our Environment

It is recently reported that some rivers and lakes have dried up in South China. A lot of fishes died. The bottoms of the rivers and lakes have become grass land. The water is becoming less and less because of the bad weather.

So everyone should do something to save our environment. First, we should save every drop of water, such as turning off the taps after using it and recycling the water. For example, we can water the plants and clean the rest room with our used water. Second, we should save energy, such as less turning on the lights and turning off the lights when we leave;Do more walking, more bicycling and less driving and so on. Third, we should ask our government to control the pollution from the factories.

Let’s act now from everything to save our environment. Don’t let our tears be the last drop of water in the world!

The population of the earth is increasing very fast. Humans must make the earth support the increasing population. This has made it necessary for agriculture and industry to develop rapidly.

Such a rapid development produces more and more waste, which goes into the water, the soil and the air. Some of it is made harmless. However, where there is too much of it, the poisonous waste may do great harm to the things around the people.

When farmers add fertilizer to the soil to make plants grow better, or use poison to kill pests, poison is sent into the air, the water and the soil. When birds, fish and people eat the grain, drink the water or breath the air, harm will be done to their health.

The air in big cities is often made very dirty by cars and factories. Millions of tons of waste and poisonous gases are sent into the air with the smoke. In some places, little is done to make the smoke clean before it goes into the air.

Fortunately, people are beginning to realize just how serious the whole situation is. In many countries, laws have been made to stop factories from sending out poisonous gases.

The most important thing is to improve people s knowledge of animal care.

Let us join hands in creating a harmonious coexistence of human and animal beautiful homes!
