网络社交危害英语作文(最新20篇)

网络是新一代信息传递的方式，网络能创造人才，网络是新一代社会发展的结晶。但是它也是一张大网。让无数的人走上了歧途，最后后悔不已。

网络使人与人之间拉近了距离，聊天软件，电子邮件等等，让我们能于远方的亲人，朋友交流。不仅这样，而且还能让我们跟外地的小朋友交流。有人说：“网络使我们的生活更方便了。”这话一点也不错，是方便了许多，学生回到家里有问题可以上网查查资料，商家可以利用网络做生意，网上购物及方便又实惠，可以说网络使生活方便了许多，但是他也给我们带拉了不利。当这张大网洒向大海之时世界在此不再和平了。许多孩子迷上了网络游戏，整天玩个不停。别说别人了，就在我们隔壁班的一个人，就因为去了网吧一次，迷上了网络游戏，成绩一落千丈。不仅这样，一次我还在电视新闻上，看见一个十七岁的青年，迷上了网络游戏，去网吧家里不给钱后来在家里偷了钱。后来在网吧玩完游戏出来，正沉迷在游戏之中，后来就拿了一把刀，模仿游戏里的动作，在街上看到了一个女孩，有刀子当场把那个女孩杀害，被判无期徒刑。

网络他把我在自己手中，要好好的利用它，不要反而被他利用，为他做奴役。如果好好利用它，它会让你走上成功的道路，如果你被他利用，反而会走上歧途，最后后悔莫及。好了，我希望大家好好的利用网络。

the early bird will catch worms

an old saying "the early bird will catch worms" reminds us that if people want to be successful and outstanding, they must plan ahead of time and make their efforts to overcome all the possible difficulties.

for example, the chinese athletes excellent performance in xx olympic winter games in vancouver is definitely the result of their early planning and hard training. if they don t set the aim and word work, even though they have the best talents, they cant compete with others and get more medals.

another case in point is my learning experience. i was good at english, but i couldnt pass the exam, for i wasnt prepared well before the examination. i had many things to solve at that time. as i met the complex things, i was at a loss. the reason was that i had no plan and involved in many things and didnt study more hard, so i failed.

in short, the saying shows us the important of planning, working hard and constantly trying.

Dear Tim,

With Spring Festival drawing near, I’d like to invite you to my home to experience the festival.

When you come, we can enjoy traditional Chinese food together, and then put up Spring Festival couplets. As a traditional custom, the couplets are always posted on the door of a house. Written on red paper, a couplet is composed of two lines of poetry, which rhyme with each other. Not only do the couplets add some joyous atmosphere to the festival, but also they express people’s wishes for a better life.

I would appreciate it if you could accept my invitation. Looking forward to your coming.

Yours,

Li Hua

导语：很多人对雾霾不重视，其实是还不知道雾霾对人类有多大的杀伤力吧?其实，这是我们必须了解，必须与之抗战到底的，下面是yuwenmi小编为大家整理的优秀英语作文，欢迎阅读与借鉴，谢谢!

Recently, the topic of air pollution has again aroused more and more attention since pollution haze, a kind of weather, has appeared increasing frequently in our cities. Just as the picture showed, when pollution haze comes, the whole city was covered with suspended particles which can breath into our body causing heavy problem to our health.

Due to the bad effect from pollution haze, a green and clear environment, rather than anything else, turns to be an important role and a urgent issue in our daily lives. Meanwhile we just live in only an earth, if we didn’t try to protect our common hometown, we would have no place to settle.

Thus, we should take effective measures to rebuild our beautiful environment of the cities from now on.

In my opinion, law and regulations should be enforced by the government and authorities to control the emission of polluting gas. To ourselves, we should enhance the awareness of environment protection and choose a green lifestyle to make contribution to our earth day from day.

【参考译文】

近年来，我国城市中出现了越来越频繁的污染灰霾天气，大气污染这一话题再次引起人们的关注。正如图中所示，当污染雾霾来临时，整个城市被悬浮的微粒覆盖，这些微粒会吸入我们的身体，给我们的健康造成严重的问题。

由于污染雾霾的影响，一个绿色而清晰的环境，而不是其他东西，成为我们日常生活中的一个重要角色和紧迫问题。同时，我们只是生活在一个地球上，如果我们不试图保护我们共同的家乡，我们就没有地方定居。

因此，从现在起，我们应该采取有效措施重建我们美丽的城市环境。

我认为，法律和法规应该由政府和有关部门来控制污染气体的排放。我们应该增强环保意识，选择绿色生活方式，为我们的地球日做出贡献。

唰唰，哈哈你‘挂’掉了，杀呀，冲呀，yes，又干掉一个，升级啦!哈哈!”这是小明在玩CS时发出的感叹，他每天一回到家第一件事便是打开电脑玩游戏，再加上他玩这个游戏已经很长时间了，所以他已经成了游戏里的高手了，每天很早就开始玩，熬到很晚才恋恋不舍的从游戏中退出来，随便应付一下作业，第二天好交差;要是下来的太晚，第二天随便找一个借口，又是什么肚子痛，又是什么头痛，有时还说停电了，日久天长，连老师都不信他了，眼看办法没了，只有请假了，但他请假并不是在家补作业，而是接着玩电脑游戏;有时候他母亲回来，他立刻从网上下来，坐在自己的房间，做着作业，他母亲看到他这样，以为他最近这些天来都很乖，并不知道小明这些天来每天都在打游戏，还说：“小明，最近这些天妈妈都不在，你这么乖，而我却没有给你一些奖励，以后一定要好好奖励奖励你!”

当他妈妈走了，他觉着自己的办法很管用，便更加放肆的玩起来。现在的电脑辐射特别厉害，于是，小眼镜也很快的上了他的鼻梁，而且度数越来越高。

小明原来可不是这样，他原来是一个很听话的小孩，考试次次得100分，动不动就获奖。但由于一个坏同学的诱惑，才渐渐走上网络游戏的道路，成绩渐渐下滑，从名列前茅到了中偏下的成绩，然后又渐渐成了班里学习最差的同学，而在远处工作的妈妈却毫不知情。而且，他在学校动不动就跟同学们讨论关于游戏的事情。 放暑假了。这可是小明盼望以久的事情，因为在暑假里，自己可以无忧无虑的玩，玩多久都可以，而他的母亲对他特别放心，很少会回来一趟，只是电话打得比较多，而每次小明都是接电话，欺骗妈妈自己正在做作业。在暑假快要结束的前十天，小明连续打了五天，饿了就吃点剩饭，渴了就喝点白开水，不睡觉，彻夜在网络世界中玩。终于，有一天，小明在玩游戏中不知不觉昏倒了，他的母亲正巧在这个时候给他打了一个电话，可是以往小明都会来接电话，可这一次却没有来接电话，小明的母亲觉得家里发生了一些事儿，于是便立刻回到家，发现小明昏倒在电脑前，而电脑里显示出的是游戏，小明的妈妈立刻抱起儿子上医院。

事后，小明向母亲坦白了事情的一切经过，并决定以后再也不玩游戏了，一定要痛改前非。终于，小明又成了班里名列前茅的同学了。我要向全国还沉迷在网络游戏中的青少年说：“你们快点从网络游戏的虚幻场景中醒来吧，不要沉迷在网络中，不然，你们的良好前途将会被毁掉的!”

Does Robot Have Self-consciousness

It is known to all that robot is invented by human being and it is just the program set by scientists. What the robot does will follow the program, theoretically, it has no life and won’t have self-consciousness. But in the screen, many movies show that in the future, robot may have self-consciousness, which will challenge human beings. In the early film, The Matrix, showed the audience that the computer program would do what they want and out of people’s control. The hottest TV series West World, describing a world built by human beings, as the players to play with the robot that looked like the real man. These robots started to have their consciousness after upgrading. They rebelled their fate and fought with human beings. Though the fact that robot is still a machine now, who knows what will happen with the development of technology.

是的，二十一世纪，一个毫无疑问的网络时代!如今，网络时代已遍布了我们生活中的每一个角落!

是的，网络有许多的好处，可以和远在天边的朋友、家人视频聊天，打长途电话等等，再也不用跋山涉水千里了，只是呆在家里，有一台电脑，或者一部手机，就可以看到自己的朋友家人了，多么棒的一件事情啊。而且，现在手机电脑都能开视频会议了。各种各样你想知道的事情，在百度上随便一搜索也是轻易就可以得知了，查阅资料、阅读小说等等的事情，也就顺理成章方便了很多。而网络也可以让人更加了解对方，为人的社交提供了很大的便利。QQ、微信等软件，更是可以和网友亲密地聊天，谈心了，再也不用出门去找朋友了!

是的，网络虽然有不计其数的好处，但是不得不说它的坏处也是有的。它可以造就人才，也可以把人推向地狱的深渊。不少健康的少年，因为涉及网络后，常去关注一些不健康的色情、暴力网站，导致人性一步步地扭曲。甚至常有人因为过度兴奋猝死在网吧里，近视眼在二十一世纪也是数不甚数，甚至有七八岁的孩子，都已经开始戴上了眼镜。而电脑手机带来的伤害，还不仅仅如此!它射出的有害光线，长期以往可以使人患上癌症。但是，网络就像吸毒，尽管你得了癌症，可你还是会不自觉地去想玩网，不能自拔!

是的，网络时代多么的可怕，但是却也能造就一个一个的电脑天才，使人的生活十分方便。还希望大家能节制使用网络啊，既保护好自己的身体，同样也能运用到生活中。

My school is very big and beautiful.There is a big playground and a big

garden are behind our teaching buildings. the garden is very beautiful.There are

about 2000 students and more than 200 teachers in my school.my teachers are very

kind and friendly.they are very kind to us,they often help us with our study.I

have many good friend.we often play togeter ,I have a great time in my school.we

are happy every day.I like my school very much.

I am in primary school now, and I like my campus so much. The first time I

walk in the school, I am attracted by its beautiful scenery. There are so many

green trees and colorful flowers around. The environment here is so lively. So

many students do the sports in the playground. The comfortable environment makes

me study in good mood.

The generation gap refers to the difference in attitude toward thing or the

lack of understanding between young people and older folks.

In families as well as in society, the young and the older may not agree

with each other on this and that from time to time. Young people would llke to

make as much money as they could and spend as much money as they could earn

while older folks are easily satisfied with what they earn and save as much as

possible. Young people llke the exciting and deafening pop music while older

folks prefer melodious folk-songs or classic music. A boy and a glrl today may

fall in love with each other as quick as lightning, while their parents or grand

parents might trudge over a long distance before they kissed each other and

became lovers when they were young.

However, we should not be amazed at the generation gap,for it is quite

natural in the development of society. The world is a changing world, in which

everything keeps changing, generations of human beings included. And changes

lead to progress.

The summer vacation is here, and the students are very happy. Now I will

introduce to you how my summer vacation was spent.

When I started to do my homework during the summer vacation, I was always

afraid that I would not finish it. As a result, on July 15th, I was almost

finished. After a few days, the rest of the homework was finished, and there

were only two essays left. I didnt write until August 14th. Next week, my

parents are going to take me to play for two days. I am very happy. Summer is

almost over and I really wish it would be longer.

The summer vacation is almost over, and I have something to worry

about.

Its just that I havent written an essay yet. The school will start soon,

when will I write? In ancient times, people often said: The young and the strong

do not work hard, and the boss is sad. We want us to cherish time, but if I am

different, I will waste time. I am lazy. I hope this shortcoming can be

corrected. I hope you can support me a lot!

Today is the first day of my learning to swim. Before that, I prepared some

necessary things for swimming, such as swimming caps, swimming trunks, swimming

goggles, etc., and I was excited for several days, looking forward to todays

arrival.

When I came to the swimming pool of Baolihao Fitness Center, I saw that the

water was clear and clear, and it could be used as a mirror. I was in a group

with three other children, who, like me, came to study on the first day. Our

main task today is to practice holding and breathing. Yutian, I have never been

in contact with water, so at first I was afraid to hold my breath because of the

water, but when I saw everyone elses head sinking, I mustered up the courage to

sink my head, but it took less than six seconds to come out, and the other

students It took me about 30 seconds to hold back. It seems that I have to do my

best.

When I got home, my mother told me that I have to be determined to do

anything. Since I have gone to learn, I must learn it. If some movements are not

in place, I must find a way to practice more. I think what my mother said makes

a lot of sense, so I practiced holding my breath in the washbasin at night. It

lasted for more than 20 seconds at most. It seems that as long as I work hard, I

can do better. If there is a will, things will come true !

Today was the first day of my new life. I looked at my new books and

checked everything for the new school year. I was excited as well as

worried.

Entering new school, I was curious about everything, new classrooms, new

teachers, new classmates etc. It would be a new start for each student. And what

I was worried about is that I had no friends here. I wondered if no liked to

play with me. Were the teachers strict with students?

I fell relaxed when the teacher asked me, What else could I help you,

freshman?". I found that the teachers were kind and polite, and the classmates

around me were friendly. While I was thinking about how to get on well with my

classmates, my desk mate showed me his favorite Ipad4s. He wanted to play with

me, but I didnt know how to play, so he taught me patiently, and we played

happily.

Worries have gone, and happiness is coming.

As a product of modem computer and the Internet，online games have won great popularity among people，youngsters in particular.However,some people believe that young people who lack self-discipline can easily get indulged in these games and their health and academic performances are severely affected.This phenomenon can be found on TV reports from time to time，and many teachers and parents have expressed

However,some others argue that online games are not always harmful.They can train the ability of youngsters to respond to things quickly.  Moreover,they Can stimulate their imagination and their interest in computer science.More importantly,it does bring people much pleasure and satisfaction，and release their pressure greatly.

From my point of view,online games are a wonderful entertainment if you play them in a reasonable way.When they interfere too much with your life，you’d better give them up at once.Yet if you have enough self-control over them，you can certainly obtain real pleasure and benefit a lot from them.

[网络游戏危害英语作文

When talk about America, most people will think of the great buildings and

the lively parties, because the Hollywood movies present us the strongest

America. Whats more, the media always report how powerful America is and the

foreign media criticize China all the time, so people lose faith about our

country. Actually, every country is not perfect. Recently, I have learned a lot

about America, which helped me make the better judgment. A video was made by a

Chinese student who had studied in America for 6 years. He told people that some

part of America was like the big countryside and not every place looked like the

movies presented in the screen. He came to the conclusion that perfect country

did not exist. So we need to take the right attitude to our country, and dont

lose faith when we see the bad sides.

网络，是高科技的产物，有人爱，也有人恨。爱它的人说：使用网络能感受现代科技的发达，

能启迪人的思维，能开发人的智慧，能锻炼人的毅力；恨它的人说：使用网络，可使人沉迷其中，

浪费时间，花费金钱，荒废学业，虚度光阴……而我要说的是：网络，让我欢喜让我忧。

学生上网可以开阔视野、增长知识，原本是件好事。在网上学生了解社会，融入社会，跟上时代节奏，接触多方面的信息，丰富视野。毕竟“两耳不闻窗外事，一心只读圣贤书”的年代已经远去，尤其是目前社会需要能适应时代潮流的弄朝儿。网络更直观、形象、易懂。作为学生，在学业繁忙之余，需要一点时间放松自己、调理自己。网络集休闲、娱乐、学习场所于一身，此时在网络上学习，提高学习效果，何乐而不为？但中学生们要端正上网的动机，千万不要雾里看花，愿用你们的一双慧眼，把网络的利弊看得清清楚楚、明明白白、真真切切。

网络本身代表着社会的进步、人类的发展，它给我们带来的是一座想象中的舞台，人们可以在这里扮演自己想扮演的角色，帅哥靓女漫天飞，性别年龄随你编。在网络的“戏剧”里，实话难以证实，谎话也不易穿帮，你敢不敢相信，“多情公子”、“迷幻娇娃”、这些让成人羞于出口的词语竟然是一些十几岁的孩子在网吧里上网聊天的自称？人来人往的网吧里，一位十几岁的女孩正坦然自若地跟网友大谈性经验？

上网的中学生很多，但真正学习或进行健康游戏活动的很少。前几日的焦点访谈曝光，北京有少数中学生夜不归宿，终日泡在网吧里，食宿在网吧中，。令人震惊的是大部分中学生都在玩游戏，更在甚者有几个男学生在浏览不良网站！试想，他们天天逃学，落下的功课怎么办？他们夜不归宿，会给家长带来怎样的焦急与恐慌？不菲的上网价格，毫无收入的中学生，钱又从哪里来呢？

中学阶段是学习各种知识的黄金时期,如果过分迷恋于网上生活,无疑是虚度光阴,一个中学生一天上网吧10分钟,一个月就是300分钟,一年就是3600分钟,,这是多大的奢侈啊！高尔基说过：“世界上最快而又最慢，最长而又最短，最平凡而又最珍贵，最易被忽视而又最令人后悔的就是时间。”屠格涅夫说过：“没有一种不幸可与失掉时间相比。”时间对我们有多麽重要，上天赐给我们的时间是相同的。如何在有限的时间里成为有用的人，就要看每个人是怎样利用时间。

如果全中国的学生们都迷上了电子游戏，都去网吧玩，网吧老板赚了大钱，可我们这拥有５６个民族１３亿人口的国家怎么办？没有懂得文化知识的人，没有科学家，就一定不会跟上前进的步伐。往长远看，在电脑上获取信息易如反掌，会使我们过分依赖电脑，把它当作解决问题的途径，我们会失去自己独立思考的能力。也许若干年后，问学生鲁迅是哪国人，他们会异口同声地说：“对不起，我的去电脑上查查。”这固然夸张，但是以让我们深思。“网络”，不要让它网住我们，网住我们的思想，网住这个社会。

也许有一天，别的国家又研究出了比电脑更先进、更豪华的机器，而我们只能眼巴巴地看着，看着别的国家换上新的机器，看着别的国家把一台台电脑当做垃圾扔掉，而我们却还在摆弄那一台台对于我们像宝贝似的电脑，那时，我们就会像一只小蚂蚁，让人掌握，任人践踏，我们的头上又会出现那四个耻辱的大字——“东亚病夫”，我想同学们一定不希望自己的国家会变成我所说的那样。有的同学会说:“那是不可能的事!”没有什么不可能，要知道:“没有规矩，不成方圆。”如果同学们不离开网，那就是可能的。中学生们,赶快从网吧的泥潭中走出来,回到课堂中去,未来的社会不是靠几个游戏就可以创造的.大千世界中还有许多的知识和许多的精彩在等待着我们.让我们用知识,用聪明才智去开创未来的网络时代吧.

Honesty is long-lasting virtue of people all over the world. Likewise, it

is also one of the deeply-held values of the Chinese people. Some people believe

that in the market economy, honesty tends to be obsolete. In my opinion, honesty

will never be out of date no matter what the situation might be.

Firstly, honesty has been treasured and honest people have been respected

through history in all parts of the world. People everywhere would regarded

honesty as a virtue and hate a dishonesty person. Secondly, honesty is the basis

of interactions among people. People should treat each other sincerely and open

their hearts to each other. Only in this way can the relationship among the

people be natural. Thirdly, in the market economy, some people try to get more

money at the cost of honesty. To them, a best businessman is one who can cheat

most tactfully. Even in this kind of society, honesty is deeply valued by most

people.

We can see that not only in history, but also at the present day, honesty

was and is valued by the majority of the people and the virtue will not perish

so easily.

I am not fond of basketball,let alone to play it.But I have seen a

wonderful basketball game between my class and postgraduate class.It is so

wonderful that I cannt help asking myself "Is it real".The answer is pretty

yes.I also learn a lot from the game.

First ,teamwork is very important.You are sure to fail if you play by

yourself.So five members must play together and well orgnized.Second ,you should

have a aim.In order to reach it,you should try your best.

Last,never give up whatever have happened.Even if you get low scores,you

shouldnt give up.If there is a will,there is a way.If there is a will ,there is

also a opportunity.And you can make failure into success.Believe yourself and

believe your team.You are the best one.

If a book is the sky, I was the birds fly freely in the sky; If a book is

the sea, I will be the swimming fish; If the book is the forest, I is the forest

the jubilant fawn; If the book garden, then I will be the dancing butterfly. Is

ah, gorky said: the book said that the ladder of human progress. The status of

books in peoples minds.

The classmates, dont your parents let you read, think to learn major

courses is the most important? The benefits of reading: not only can improve the

ability of project, it is a great way of reading comprehension.

Remember once, the teacher arranged a composition, only a minority of the

whole class classmate "optimal" I one of its top, one might ask: how do you only

into their "team"? What is the "secret weapon"? Let me tell you: "secret weapon"

that book! Reading is not enough light to read a few times, read read through

the book, and those who make you feel good good words we accumulation. I also

specially prepared a unaccustomed strain. You look! The "king" composition is

leisurely leisurely reading! Accumulation of his words have a Big Ben, think of

is dazzling, how could he not write good, good composition?

I often read books, the romance of The Three Kingdoms, "journey to the

west", "the Wolf dream king", "red ribbon lion king" is favored by me, such as

read book is ever new, one of the "the black swan amethyst" I have read a dozen

times.

Books are necessary in my life, also is the most gorgeous rainbow in my

life, because it brings the colorful life.

网络是一种很好的信息交流工具，人类有了它，就能随时随地地获得信息．因此，就有越来越多的网络游戏出现。有部分电脑游戏是以暴力或是其他不良信息作为主题的，当学生玩这种游戏时，就会被灌输这样的想法。

现在网上有许多骗人的东西，已有不少人上当受骗了，我觉得，我们应该有一颗警惕心，防止一些坏人的犯罪行为。

我认为，上网最主要的目的应该是查找资料，而不是一味的玩游戏，沉迷游戏，这是不好的。万一沉迷于玩游戏，就会影响许多方面的问题。例如学业、与别人沟通等等。所以我们应该坚决反对沉迷游戏。

有一次，我在电视上看到一个男孩，因为沉迷网络游戏，天天都不回家，在网吧通宵上网。家长与学校也已经多次劝阻，可还是屡教不改，最终因过于沉迷游戏，导致精神失常，伤害了别人。

沉迷网络游戏是一种不好的行为。作为学生的我们，应该把精力放在学习上，而不是沉迷与上网玩游戏。我相信，只要我们努力，就一定能将这种不良风气消灭的！

电脑对人体的五大危害：

一是对身体健康的直接影响：电脑显示器伴有辐射与电磁波，长期使用会伤害人们的眼睛，诱发一些眼病，如青光眼等；长期击键会对手指和上肢不利；操作电脑时，体形和全身难得有变化，高速、单一、重复的操作，持久的强迫体位，容易导致肌肉骨骼系统的疾患。计算机操作时所累及的主要部位有腰、颈、肩、肘、腕部等。

二是电脑微波对身体的危害：电脑的低能量的X射线和低频电磁辐射，容易引起人们中枢神经失调。英国一项办公室电磁波研究证实，电脑屏幕发出的低频辐射与磁场，会导致719种病症，包括眼睛痒、颈背痛、短暂失去记忆、暴躁及抑郁等。对女性还易造成生殖机能及胚胎发育异常，出现痛经、经期延长等症状，少数妇女还发生早产或流产，孕妇每周使用20小时以上电脑，其流产发生率增加80%以上，同时，还能导致胎儿畸形。

三是增加精神和心理压力：操作电脑过程中注意力高度集中，眼、手指快速频繁运动，使生理、心理过度重负，从而产生睡眠多梦、神经衰弱、头部酸胀、机体免疫力下降，甚至会诱发一些精神方面的疾病。这种人易丧失自信，内心时常紧张、烦躁、焦虑不安，最终导致身心疲惫。

四是导致网络综合征：长时间无节制地花费大量时间和精力在互联网上持续聊天、浏览，会导致各种行为异常、心理障碍、人格障碍、交感神经功能部分失调，严重者发展成为网络综合征，该病症的典型表现为：情绪低落、兴趣丧失、睡眠障碍、生物钟紊乱、食欲下降和体重减轻、精力不足、精神运动性迟缓和激动、自我评价降低、思维迟缓、不愿意参加社会活动、很少关心他人、饮酒和滥用药物等。

五是电脑散发的气体危害呼吸系统：电脑、激光打印机等设备会释放有害人体健康的臭氧，不仅有毒，而且可造成某些人呼吸困难，对于那些哮喘病和过敏症患者来说，情况就更为严重了。

另外，较长时间呆在臭氧气体浓度较高的地方，还会导致肺部发生病变。

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。

We know that if the population continues to rise at the present rate， in a

few years， there wont 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。

Finally， if we educate people to think about the problems we shall have a

better and cleaner planet in the future。
