中学生英语演讲稿保护大自然2篇 作文怎么写(精彩20篇)

In fact, there are many things that can seriously pollute the environment: litter, spitting, grass and so on. The consequences are severe. But the waste of resources cannot be ignored. The worst is the waste of water.

At present, the reform and development of our country is at a critical juncture, and we should strive to achieve the goal of building a moderately prosperous society in all respects. But there are still some problems -- our living environment is seriously polluted; And the green resources are falling.

We do a lot of what the environment, such as: on one occasion, in a clean small garden, there have been some rubbish, gradually where there are a lot of people throw garbage, there is a garbage dump. It turned out that the trees were green and the flowers and grass were blooming. The bees and the butterflies were there, and there was a smell of enchantment. But now, there was nothing to do with it, and the smell of it was so bad that no one was willing to stay there any longer. Alas! It is a pity that such a beautiful garden is gone. If people notice that they dont pollute the environment, now, by the way, its a kind of escape. And, what a wonderful thing for people to have a rest and take advantage of the cold. But now its a junkyard, and the consequences of polluting the environment are terrible.

And there are a lot of factory waste is also pollute the environment, but the most serious is the pollution of water, I heard of such a story: there was a village, there was a clear pool. There were lotus flowers in the water and the goldfish, and it was so beautiful that visitors to the village would not forget to take a look at the scene. And people in the village wash and cook and drink water and water, so the water is very precious. One day, a businessman opened a factory near the pond, and the factory shut down a lot of waste water and garbage and went into the pond... The result can be imagined: the goldfish died, the water side became the sewage, the tourists no longer came, the people in the village moved away... Alas! The little pond has disappeared. The factory severely polluted the environment and made the environment in the village very bad and affected peoples lives. Its a story, but there are a lot of these things in everyday life, and the results are very serious, not just simple consequences.

In fact, there are many things that can seriously pollute the environment: litter, spitting, grass and so on. The consequences are severe. But the waste of resources cannot be ignored. The worst is the waste of water.

Now, Beijing is a city of severe water shortages, but there are a lot of people in the waste water, such as: there are a lot of people out of the water to wash the dishes and laundry water and reuse. In fact, although can only save a little water, economy is a lot of!

Also, people who sell fish in the market love to put a faucet on the side of the water, and when they use water, they will let the water flow freely. How much water they would waste if they went on like this!

The drink, the wine, etc., are now made with water. Some factories use a lot of water, so some of the water is wasted. Thats a lot of wasted water. This water can do a lot if you save it! You can also avoid a little water.

不知从何时起，“雾霾”、“PM2.5”这些可怕的单词频繁地出现在我们的日常生活里，尾气排放、噪音等伴随着我们艰难地成长，生活在城市里的我们，很难再看到夜晚星空的璀璨，很难再聆听百灵鸟清脆的歌声，好怀念那些青山悠悠、绿水长流的日子，那份古朴的气息直到现在依然还刻划在我们每个人的心里。有机会离开渲嚣热闹的城市，我们义无反顾地投入了大自然母亲的怀抱，像迷失方向的孩子终于找到了妈妈，忍不住钻进她的怀里撒起娇来。

看，柳芽儿摇曳着曼妙的身段，小花儿羞羞答答地露出了粉红的脸蛋，春风拂过脸颊留下了一丝暖意，掠过了轻柔的长发，“阳春布德泽，万物生光辉”，那是春的明媚和温暖。

当一楼斜阳慵懒地照射进庭院，当知了发出了扰人的鸣叫，当荷花绽放出了别样的丰采，当天空开始像小娃娃一般毫无征兆地时而哭时而笑时，我们知道，那是夏的炽热和壮丽。

满城的稻谷吐露出金黄色的芬芳，翻滚着煞是好看的千层波浪，瓜果飘香，争奇斗艳，丰收的喜悦就在眼前，但绝不妖娆，绝不霸道，秋水共长天一色，那是秋的含蓄和大气。

清洌的空气中传来了爆竹声声，白雪皑皑像是给大地盖了上一层厚厚的雪毯，薄薄的层雾中吹起了袅袅炊烟，让人仿佛置身于人间仙境，冰清玉洁的梅花傲然独立，喧香远溢，那是冬的淡泊和迷人。

如此这般美丽的大自然，我们怎忍心让她受伤?古人云：“竭泽而渔，岂不得鱼，而明年无鱼。”作为现代人的我们，更应该懂得如何去保护我们的大自然，保护我们周边的环境，不要一味地乱砍乱伐，节约我们有限的水资源，保护可爱的动物们......大自然的生命需要我们悉心地延续，为了让我们能头顶一片纯净的蓝天，脚踩一个富有神韵的大地，让我们携手“亲近自然，保护环境”，记住：没有自然就没有人类!莫“竭泽而渔”!

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!

In recent years, drought has prevailed in northern parts of our country. There is no or only little rain in spring and summer in the noth and northeast of China. The same is true of snow in winter.

Consequently, big cities such as Beijing and Tianjin are short of water every year, which affects the life of the urban people and the production of factories. And the drought is most felt by crops in rural areas, of course. It is said the drought has much to do with the "green house effect" and the "greenhouse effect" is caused by the pollution of the atmosphere. In the final analysis, it is brought about by ourselves.

Faced with the terrible drought, we should stop polluting the air right away. We should try all means to decrease the amount of poisonous gases which our factories and cars give off. Besides, we should take measures to protect the forests and plant as many trees as possible.

大自然的环保是地球上所有人应做到的事，可是现在市民的生活水平有所提高，所以对我们的地球卫生不太重视了。

当我们路过小渠边，看到渠边的垃圾，由此我们便猜想到如果我们是绿树是小草是鲜花，鲜花是人小草是人绿树是人，如果他们把我们掩埋在垃圾下面，那我们会是什么样的感受，可以转化一下思想，如果植物会说话，它们一定会劝告人们不要破坏环境，其实我们也是这其中的一员，大家应该彼此关爱，彼此帮助，关爱植物等于是关爱人类自己一样，所以从现在开始我们应该保护环境，做一个环保者。

尊重有些人看不起捡垃圾的人，说他们不讲卫生，其实我认为，捡垃圾的人有一种内在的品质，因为他们知道他们所收集的垃圾对他们有两个有利的地方：一是可以卖一些垃圾赚钱，二是可以保护环境卫生。其实清洁工也想让人们每天能够呼吸新鲜空气，让人们有一个好身体。所以我们应该感谢捡垃圾的人，他们不但给我们带来了健康的好身体，还让我们呼吸大自然的气息。

环保生活中的点点滴滴存在着环保，我们应该从我们身边的小事做起，保护保护地球保护家！

In the past, there have been many endangered animals. Now they are extinct. Does it matterHas our environment been affected by their absenceHas the quality of our own life been changedThe answer to these questions is “Yes.”

It does matter if we destroy an endangered species habitat to develop more farmland, housing or industrial parks.It will effect all the other creature.

For example, if certain trees are cut down, birds and bats will have no place to roost.They cannot roost, they cannot breed. If there are no bats or brids, there will be no animal to eat certain insects that plague our crops.

Jungle around the world are being cut down to make room for humans. We will never be able to see or study this fragile ecosystem.

Human beings should be responsible for their own acts of nature. The promulgation of laws to maintain ecological balance, to make more space and natural. Conservation biology, Protect environment, protection of natural.

My house have a garden downstairs, where flowers bloom all the year round, is the main place to neighbors leisure entertainment. The children often play there, I also liked to play there.

Homework today, I came to visit my good friends in the garden, flowers, they found flowers side there are a lot of rubbish. Think of "the teacher said to protect the environment is the responsibility of each one of us", I immediately ran over to pick up all the rubbish into the dustbin, at this moment, the other side of the garden came the cries of children: Peng Linqian, come and play! I cant help but stopped, the in the mind like two little quarrelling, pick up, afraid of see after children, said I was picking up litter. Dont pick up, let the garbage lying there quietly? Because of this problem, let me in a quandary. Pick up or not pick up? Ask mom and dad to say again!

Mom and dad is walking toward the side, and the father said, "of course it is important to environmental protection, you should start from around things, do not litter. If you see a garbage on the ground, should pick it up, so that you do to protect the environment." Mom said so.

Mom and dad gave me courage. Environmental protection is more important than face, they would say I am picking up litter and let them say! I dont care now. If a man pick up a garbage, more people will be able to pick up more junk. Earth must be the earth more than it is now clean and more beautiful.

Without hesitation, I run past, all the trash in the underground (bin) back to their home. Then, the people around to me to approval.

我家楼下有一个花园，那里一年四季都有鲜花盛开，是邻居们休闲娱乐的主要场所。小朋友们也经常在那里嬉戏，我也特别喜欢到那里玩。

今天做完作业，我又来到花园里看望我的那些好朋友——花，却发现花儿的身边有很多垃圾。想到老师说的"保护环境是我们每一个人应尽的责任"，我立刻跑过去准备把垃圾都捡起来送进垃圾箱，这时，花园的另一边传来小朋友的喊声：彭林茜，快来玩!我不禁停住了脚步，心里像有两个小人在吵架，捡，怕小朋友看见后，说我是捡垃圾的。不捡，就让垃圾静静的躺在那儿?就因为这个问题，让我左右为难。捡还是不捡?问问爸爸妈妈再说吧!

爸爸妈妈正好也朝这边走来，爸爸说："那当然是环保重要，你要从身边的小事做起，不要乱扔垃圾。如果看到地上有垃圾，当然应该捡起来，这样你就为保护环境做了贡献。"妈妈也这么说。

爸爸妈妈的话给了我勇气。环保比面子更重要，他们要说我是捡垃圾的就让他们去说吧!我现在不在乎了。要是一人捡一次垃圾，更多的人就能捡更多的垃圾。那时候的地球一定比现在的地球更干净，更美丽。

我毫不犹豫地跑过去，把地下的垃圾全部送回了他们的家(垃圾箱)。这时，周围的人们向我投来赞许的目光。

Do you know of any endangered animals? Why are they in danger? I think there are many endangered animals in the world, such as tigers and pandas. When farmers cut down trees, tigers can no longer hide and hunt. Many tigers are killed by people who want to sell their fur for money. And there are few places where pandas can live. We are not alone in the world. We human beings could not live without all the plants and animals around us. So protecting wildlife animals are very important. We must take measures to keep plants from being destroyed and stop animals from being killed. If each of us can plant a tree and build a birdhouse, the world will be more beautiful. It is very easy but useful.

你知道任何濒危动物吗?他们为什么处于危险中?我认为世界上有许多濒危动物,如老虎和熊猫。当农民砍伐树木,老虎再也无法隐藏和狩猎。很多老虎都被那些想要出售他们的毛皮。,很少有熊猫生活的地方。世界上我们并不孤单。我们人类离不开我们周围所有的植物和动物。所以保护野生动物是非常重要的。我们必须采取措施防止植物被破坏,阻止动物被杀。如果我们每个人都可以种一棵树和建立一个禽舍,世界将会更美丽。它非常容易,但很有用。

Many people simply regard Pride and Prejudice as a love story, but in my opinion, this book is an illustration of the society at that time. She perfectly reflected the relation between money and marriage at her time and gave the people in her works vivid characters.

许多人认为这只是一个爱情故事傲慢与偏见，但在我看来，这本书是对当时社会的例证。她完美地体现了金钱与婚姻关系时，给她的时间在她的作品生动的人物形象的人。

The characters have their own personalities. Mrs. Bennet is a woman who makes great efforts to marry off her daughters. Mr. Bingley is a friendly young man, but his friend, Mr. Darcy, is a very proud man who seems to always feel superior. Even the five daughters in Bennet family are very different. Jane is simple, innocent and never speaks evil of others. Elizabeth is a clever girl who always has her own opinion. Mary likes reading classic books. (Actually she is a pedant.) Kitty doesn’t have her own opinion but likes to follow her sister, Lydia. Lydia is a girl who follows exotic things, handsome man, and is somehow a little profligate. When I read the book, I can always find the same personalities in the society now. That is why I think this book is indeed the representative of the society in Britain in the 18th century.

书中的人物有自己的个性。班纳特太太是一个女人谁使大力女儿嫁出去。彬格莱先生是位很友好的年轻人，但他的朋友，达西先生，是一个非常骄傲的人谁似乎总是感觉优越。即使是班纳特家的五个女儿有很大的不同。简是简单，天真，从不说别人的恶。伊丽莎白是一个聪明的女孩谁总是有她自己的意见。玛丽喜欢阅读古典书籍。 (其实她是一个学究。)小鹰没有她自己的意见，而是喜欢跟她的妹妹，莉迪亚。莉迪亚是一个女孩谁如下异国情调的东西，英俊的男子，并在某种程度上有点挥霍。当我读的书，我总能在社会上找到相同的人物了。这就是为什么我觉得这本书确实是在英国社会在18世纪的代表。

The family of gentleman in the countryside is Jane Austen’s favourite topic. But this little topic can reflect big problems. It concludes the stratum situation and economic relationships in Britain in her century. You can find these from the very beginning of this book.

The first sentence in this book is impressive. It reads: “It is a truth well known to all the world that an unmarried man in possession of a large fortune must be in need of a wife”. The undertone is very clear: the foundation of the marriage at that time is not emotion but possession.

在农村家庭是简奥斯汀先生最喜欢的话题。但是，这个小问题都可以反映大的问题。它总结了地层情况和英国的经济关系，她的世纪。你可以找到从一开始这本书。

在这本书的第一句话让人印象深刻。它写道：“这是众所周知的，在世界上的一大笔财富占有未婚男子必须在妻子需要一个真相“。该底色是非常明确的：当时的婚姻的基础是感情，但不占有。

People always think that Austen was an expert at telling love stories. In fact, the marriage in her book is not the result of love, but the result of economic needs. After reading this book, I know the truth is that a poor woman must be in need of a husband, a wealthy man.

I couldn’t forget how eager Mrs. Bennet wants to marry off her daughters. If you want to know why she is so crazy about these things, I must mention the situation in Britain at that time. Only the eldest son had the privilege of inheriting his father’s possessions. Younger sons and daughters who are used to luxurious lives have no choice but marry a man or woman in possession of a large fortune to continue their comfortable lives. Thus, we can see that getting married is a way to become wealthier, particularly for women without many possessions. Jane Austen told us that money and possession determined everything, including marriage and love in her century.

读书认字、看图赏画、看人物、欣赏美景等都要用到眼睛。 所以我们要保护好自己的眼睛。

生态文明是人类文明的新发展，它与物质文明、精神文明和政治文明具有同样重要的地位 。环境和人类与大自然的和谐是密切相关的，生态环境得到改善，就能推动整个社会走上生活富裕、良好的文明高速路。

工业文明给人类带来了巨大的收获，但生态文明却一步一步的离开人们，可人们还是不把生态放在眼中。直到近几年全球气候变暖，人们才意识到生态环境的重要性，大规模的宣传“保护环境，人人有责”，可地球早已被他们破坏的千疮百孔。地球在近几年受伤害的数字令人瞠目结舌。例如，目前地球上的动植物大约每天有100个物种从地球上消失。在第三世界由水污染引起的疾病平均每天导致的死亡人数达2.5万人。或许大家以为这些都是外国的灾难，但今年我国北京、天津、上海等地多次发生的历史上罕见的沙尘暴天气，使得中国人感受到了环境破坏程度之深和距离之近。

生态文明具有丰富的内容。就其内涵而言，主要包括生态意识文明、生态制度文明和生态行为文明三个方面。改革开放以来，党一直强调生态文明。党的十七大报告在阐述实现全面建设小康社会奋斗目标的新要求时，第一次明确提出建设生态文明，搞好生态文明建设。国家领导人对生态的问题一次次的进行讨论和研究，最终得出我国生态污染严重超标的结果。

生态灾害最直接的恶果就是经济，据说我国每年要拿出2000亿人民币来用于受生态灾难影响的地区的补偿。生态已经与人类的生死存亡息息相关了，人类才开始珍惜它，未免有些太迟了。

曾记否，我们的前人生活环境是那样的美好：花在草地上展开笑脸，鸟儿在天空中无忧无虑地飞着，鱼在水中游来游去……如今，面对满目疮痍的地球，我们是否应该深深地反思：时代要进步，文明要发展，人类向大自然一味掠夺式的索取生活方式不可取。我们人类作为高等动物，却连低等动物保护家园的意识也没有，是不是太不配了?

生态文明教育是一种把人的问题提到一个新的高度，我们小学生更应该受这种教育。我们应该知道，地球上的资源是有限的，而如今人类的乱砍滥伐，使原本美丽的地球变得不堪一击。我们一定要更加珍惜生态，不让它在我们手中化成碎片。我们要提高生态文明意识，从身边的一点一滴做起，尽量少用一次性物品，节约一滴水、一度电，不乱扔白色垃圾、废电池，形成自觉的行动，不浪费身边的资源，做到真正的低碳生活。

我们作为小学生，在抓紧教育的今天，更应该知道生态文明的重要性，我们应该将它作为一种不可估量的财富，珍惜它，爱护它。我们应该吸取上一辈人的经验，珍惜资源，把地球变成一个更加灿烂与辉煌的星球!

在一次又一次工业革命的推动下，人们的生活一次比一次便捷，一次比一次美满，物质生活也一次比一次丰富，但人们在享受这种肉体的满足时，似乎忘记了我们从哪来，是谁一直哺育我们。而我们却仿佛理所当然，一次又一次的去破坏它，从而去满足我们。

“足不出门知天下事。”打开电脑，轻点鼠标，我们可以知道上下五千年的历史文化，知道生物的纲目属种，知道一天内的最新新闻。还可以利用社交软件跨洋进行视频聊天，但我们似乎都忘记了，你可以上知五千年的历史文化，却感受不出五千年的文化乐趣，你如白科全书一般知道生物的纲目属种，却无法嗅到花果清香、丛林气息，你知道一天内发生的所有事情，可以与远在他乡的人们进行聊天，却不知静观云卷风舒和朋友相会的乐趣。我们一次又一次的享受工业革命带来的成果，一次又一次的破坏我们共同的家“自然”。自然给我们带来了生命，给我们带来了知识，我们却不懂回报，一次又一次的伤害着自然，孰不知，我们在远离着自然。

我们坐在家中，吹着空调带来的阵阵舒适，人们一次又一次的开垦树林，把一幢幢高楼建在自然一块块伤疤上去，自然尽管在默许你们的开垦，但自私的人们却不知，我们正在自取灭亡。我们必须保护大自然，不能将自然离我们越来越远。

爱因斯坦说过：“我一生中最后悔的事情便是将核导弹带到这个世界上来。”爱迪生也将死后所有财产设立了一个闻名的奖，其中也有一项和平奖，因为和平减少了战争，同时也保护了自然。自然是我们共同的家园，我们必须去保护它，去爱护它，而不是去破坏它，远离它。我们国家也在倡导绿色GDP，发展绿色的、健康的产品，仿佛这个世纪都离不开保护自然。同时也要多去感受自然，去捕捉大自然的一点一滴，这样有利于我们自身的健康成长，有利于提高我们的修养。

我在书在看到过一句名言：“世界上最无私的东西便是太阳，无论你地位高低，无论你财富的多与少，它都会无私的照亮在每个人的身上。”同样，大然自也无非是这样，我们要多去亲近自然。

蓝蓝的天空白云飘动，清清的水中鱼儿畅游：翠绿的森林染遍原野，欢快的鸟儿处处鸣唱。大自然赐给我们一个清纯的家，这就是人类世代生存的环境。

不知从什么时候开始，山不再那么绿，水也不再那么清，垃圾废物堆成山，连透明的空气也变得灰蒙蒙。

下面是我经过详细调查发现的原因：

一、当森林火灾、工业废气和汽车排出来的尾气等有害的气体和尘埃进入空气时，空气自然就会被污染，天空也就变得灰蒙蒙。

二、我们的生命离不开水，其中生活污水、工业污水、农业污水这三种污染较为常见。农业污水的污染范围最大，主要是因为过量的施用化肥和农药引起的。化肥和农药随着农田排水和雨水流入江河湖泊。

三、现代大多数的人都有一个坏习惯，那就是乱扔垃圾。许多人贪图方便，随手把手中的果皮、塑料袋等垃圾扔掉，造成满地垃圾。

我在这里呼吁大家一定要保护好大自然，热爱地球，因为这是我们共同生存的家。如果随意破坏环境，那就等于加速环境恶化，也就是在缩短自己的寿命。让我们携手创一个干净温馨的家，愿我们的天更蓝，水更清！让生命之花继续生机勃勃地生长下去。

我热爱地球，热爱我们赖以生存的大自然。爱他的花草树木，爱她的碧水蓝天，爱她的硕果飘香……在硕果飘香的花丛中，蜜蜂和蝴蝶一起嬉戏，欢笑;在郁郁葱葱的树下，我与伙伴一起追逐，歌唱;清晨，我迈着轻盈的步履去学校上课。阳光明媚，如同给大地披上了金色的纱衣，光线照在树叶上，熠熠发光。我允吸着花草的芳香，欣享着阳光的沐浴，我被这美丽的景色陶醉了。夜晚，我坐在楼下，仰望着璀璨的星空，倾听着无数星星的诉说，仿佛置身于一个童话般的王国。曾经，人们乱砍乱伐，使美丽的大自然遭到破坏。沙丘吞噬了万顷良田，洪水冲毁了我们可爱的家园，大自然的惩罚让人类悔不当初。梅水溪曾说过：“没有自然，便没有人类。”这是世界的真理。一味的掠夺自然，征服自然，只会破坏生态系统，咎由自取，使人类陷入困境。这句话说的一点也不错，人不给自然留面子，自然当然也不会给人留后路。曾经，战争的爆发，使我们赖以生存的地球变成残山剩水，炮火对植物的破坏，对生命的摧残，由此可见，和平是全人类绿色环保的重要前提。真不敢想象，如果我们再这样继续下去，这个世界将会是一副怎样的惨景呢?地上寸草不生，天空沙尘弥漫，人类将在魔鬼般的尖叫声中变化成堆堆白骨。到那时我们只能说，人类曾经属于地球，但地球将永远不属于人类了。地球母亲对我们发出劝告：“河湖，草原是你们赖以生存的基本条件。破坏自然环境等于自己毁灭自己。希望你们赶快行动起来，保护环境。只有这样，我才会重新焕发青春，使你们人类生活的更美好。”希望地球母亲的幻想能变成现实。让我们一起扞卫我们美好的家园吧!

The Marine life environment is a complex system including seawater, sea water content and suspension, seabed sediment and Marine life.The abundant biological resources, mineral resources, chemical resources and power resources of the sea are the indispensable resources of human beings, which are closely related to the survival and development of human beings.

The main objective of Marine conservation is to protect Marine life resources so that they are not depleted for sustainable use.Special priority should be given to protecting Marine life that is valuable and endangered.According to the relevant departments of the investigation, due to overfishing, accidental killing of non-target to allow hunting of Marine, coastal tidal flats in the engineering construction, mangrove deforestation, widespread Marine pollution, at least 25 in the worlds most valuable fisheries resources exhausted, whales, turtles, manatees and many other Marine animals are in danger of extinction.With the expansion of Marine development, the potential for greater damage to Marine biological resources is expected.

The trickle of water was crystal clear, accompanied by the sound of the "ding dong" of the spring. The undulating mountain stands erect, majestic and overwhelming; The green trees, towering above the tops of the mountains, are not afraid to be afraid; The wild flowers, which are in the top of the mountain, are full of beauty and beauty, and the fresh flowers are pleasing to the soul. But that was all have become memories, is facing a murky water, batteries, plastic bags have polluted the land, industrial waste gas, automobile exhaust pollution the air, trees and flowers are hard to meet again, only can see is just a weak looking trees flowers and plants, all everything has disappeared, the earth on a red alert. The presidents of all countries have been together for three days and three nights... "The whole people moved to the moon," they were consulted, and they issued such an order. According to the scientists observed earth damage is too severe, human will not far from the end of the world, if you dont leave the earth, mankind had to count the days such as dead. The present moon, which has been constructed by human ancestors and modern humans, has been transformed.

The lush woods, the crystal clear water, the blue sky, and the various shapes of flowers and animals. "Wow! This is like a new earth, and it brings us back to the old days." people dont sigh. Yes, the moon has now and once the earth is almost the same as the air around the moon, the moons gravity, and thick atmosphere around the moon, everything seemed to go back to the once upon a time, people are living down here... "Wow! There are so many trees here! ", "wow! There are so many rivers here!" Greed once again led the human hand into the abyss...

For a long time, the moon returned to the earth and the earth was devastated, and everything on the moon was dead. All the pollution to the moon, the atmosphere became thin almost close to zero, tragedy staged again, once upon a certain day a diameter of 40 kilometers meteorite broke into the moon, because the moons atmosphere is too thin, almost no resistance, is this meteorite is easy to break into the moon, because there is almost no resistance, meteorite impact force is very big, hit ground surface cracked a big hole, the hot, liquid mass of molten rock from cracks in shock... Facing death of that a moment, human beings finally wake up, but the wake up, now is just unable to struggle, ridiculous human this time really redeemed himself again. The world has been destroyed, mankind has perished.

The quality of human life has improved greatly over the past few centuries, but Earth is being harmed more and more by human activity. As we develop our technology, we demand more from our planet. Eventually, this will harm people as well.

Our planet gives us everything we need, but natural resources are not endless. Strip mining devastates whole regions, leaving bare and useless ground. Deforestation removes old growth trees that cant be replaced. Too much fishing may harm fish populations to the point where they cant recover. We are too careless in taking what we want without giving anything back.

There are more people than ever, living longer that ever. So is it any surprise that many areas suffer from too much development? Anyone living in or near a city has experienced "urban sprawl". There is a new shopping area on every corner and new houses, townhouses and apartments everywhere. Traffic gets worse and worse because planners cant keep up with growth. Keeping up with human demand is hard enough. Environmental concerns come in last.

With growth comes pollution. Companies and communities dump waste into water. Landfills are full of trash. Emissions from factories pollute the air. Barrels of industrial waste and worse, radioactive waste, have no safe place to go. If were not careful, we can harm our planet beyond repair.

People need to respect the Earth and try to preserve it. If we dont, what kind of future will we have?

Dear Bill,

I’m glad to receive your letter,thank you for your caring for the weather and my health.Now I’d like to tell you something about the smog.

Since the winter last year,the smog has occurred a lot of times.it has done great harm to our daily life.many traffic accidents happened just because of the heavy smog weather,more and more people have to go to see the doctor because the serious disease caused by the smog,quite a lot of flights have to be put off,a great number of people have to stay at home for fear of the poisonous air caused by the smog.

People have realized the great harm caused by the smog and the importance of protecting the environment.people all over the country are taking measures to reduce the smog weather.the government suggests people go to work or school with the public traffic, such as the bus and the underground.Also we should plant more trees.

According to me, I will go to school by bike or on foot, and I won’t throw the waste anywhere.in addition, I will tell the people I meet to protect the environment as possible as they can.would you like to tell me some good ideas?i’m looking forward to your reply.
