In recent years, many nations have bee more aware of the environmental issues each nation faces, such as air and water pollution。 The question is, are the environmental issues a national problem or an international problem? It is my belief that the environmental issues have grown to the point of being an international problem needing international cooperation to resolve。

Because of the differences in environmental policies, resources and technology, international cooperation could provide quicker results and have a greater impact on bringing resolution to environmental problems for nations of differing environmental policies and of lesser resources and technology。 By pooling international resources and technology to address the environmental problems, the disadvantaged nations are provided the assistance needed。 Otherwise their environmental conditions deteriorate ultimately affecting the resources and environment of the world as a whole。

One of the difficulities to an international resolution to environmental issues is the difference in individual nations view and policies toward environmental protection。 In order for international cooperation to occur and succeed, the nations of the world must submit themselved to international standards and supervision by an international mission elected by the participating nations of the world。 All members must agree to abide by the standards established。

The environmental issues facing each country are not unrelated to the well being of the rest of the world。 The impact is long term and international in scope。 Without international cooperation and agreement to address such environmental issues as glacial melting at the South Pole, depletion of the ozone layer, water pollution, air polution, etc。, the environmental conditions of the world will deteriorate to the detriment of every nation, not just those that ignore or lack the resources and technology to resolve their individual environmental problems。

As part of the same planet, it is the responsibility of each individual and nation to protect the global environment。 Only international cooperation will provide the timely solutions and the effectiveness needed to stop the deteriorating global environment。

今天下午,我和妈妈去广场,我们看到满地的垃圾,有塑料瓶、塑料袋和一些零食袋子,这个时候我想起了老师给我们布置的作业,就是拍一些破坏环境的一些照片。

所以我们就把这些拍了几张。我们又看到有人把抽的烟,火还没有灭,就扔在小草上面。我们把这些拍下来,又把烟踩灭之后劝告那个人:抽完烟以后要灭掉扔进垃圾桶里。

然后,我们回家了。又在四小旁边看到有人在烧东西,破坏空气。所以也拍了下来。

我们回了家从这三张里选一张,我就选了在四小旁边烧东西的照片,发给了老师。

我们要是不保护环境,地球爷爷就会很难受。

We can do a lot in our daily life to achieve the goal of living low carbon life.

一个星期五的下午,海洋学院的大姐给我们上了一堂“保护地球,保护环境”的班会课。

先是一个胖乎乎的大姐姐给我们讲了非常完美的寓言故事,讲的是因为人类不保护环境,大海里的小鱼都死了,我想:我们应该保护环境,不乱扔垃圾,看到别人不保护环境要劝告。我们都听得津津有味。

这时,另一个大姐带我们去操场上画画。我是第一组的,所以由我们先画。我想:保护环境就是让花儿开得更艳,让鸟儿飞得更高。于是,我兴致勃勃地拿起画笔,在画布上画了美丽的花朵和几只小鸟,我由衷地祝愿:让小鸟在蔚蓝的天空中自由自在地翱翔吧!其他小朋友也在认真地想,仔细地观察、,动情地画。不一会,一幅五光十色、绚丽多彩的画出现在我们眼前。

最后,我们用画当作背景,拍了一张美丽的照片。

下课铃声响了,我依依不舍地跑进教室。我对这节班会课真是记忆犹新啊!

现在我们的环境真是越来越糟糕了。

在过去,我们的环境那是非常舒适的,森林郁郁葱葱,河水清澈见底,空气清新甜润,地上垃圾也是非常少。马路上,没有汽车行驶排出的尾气,两旁都种着许多花草树木,蜻蜓和蝴蝶在草丛中嬉戏玩耍,真是一片美好!

可是现在,人们为了让这个世界变得更加方便,于是人们制造了汽车,汽车排出的尾气不仅污染了地球,还会造成对人们身体的伤害。一年又一年汽车越来越多,树木越来越少,环境也是越来越差,以前的美好环境都消失了。

我真希望人们能认识到自己所犯的错误,我希望十年后的家乡是这样的。清早起来空气清新,天空湛蓝深远。烟囱、汽车不再排放废气,河水不再浑浊,清澈的可以看见水里的沉淀的泥沙和水草,甚至我们都能在里面游泳了。家乡的环境又变美丽了。

为了保护我们的地球,我们应该从点点滴滴做起,从生活中的小事做起,让我们都行动起来,一起来保护我们共同的家园。

我们此刻的环境太差了:垃圾到处都这样,人们随地吐痰,随地大小便。在我们周围,空气不清新了,水变的不清澈了,沙尘暴越来越多了。

有一天,走在大街上看见形形色色的人,他们一个个戴着口罩,包着脑蛋行色匆匆,从他们的眼光中看出了对环境的无奈。他们为什么都这样这样的打扮呢?因为这都这样可怕的沙尘暴使人们生活在层层包裹之中。沙尘暴来袭这样令人可怕的,大风夹杂着尘土和沙砾肆无忌惮的刮风向人们生存的土地,哪怕这样小小的缝隙也不放过,沙尘刮向农田尘土附着在刚出生的小苗上能够导致农作物不能够进行正常的光合作用,最终导致农作物因营养不良使产量下降,沙尘也这样一些疾病的“传播者”尘土吸入人们的口腔中会造成许多呼吸道疾下方这样一个真实的例子。

黄河流域自古这样我们中华民族的摇篮,也这样世界古代礼貌的发扬地之一。黄河,作为中华民族的摇篮和母亲河,不仅仅传承着几千年的历史礼貌,而且也养育着祖国8。1%的人口。然而,目前黄河流域的生态危机正在日益加剧,并且面临着土地荒漠化,水资源短缺,水土流失面积增大,水污染严重,断流加剧,生存环境恶化等诸多问题交织的严峻形势,给我们发出了严重的警示。

仅仅这样一个例子,就这样这样的令人可怕,这一切都这样因为人类贪梦的向大自然过度的索取造成的,如果人类继续这样执迷不悟下去,那么,我们赖以生存的环境将一去不复返,到那个时候,这个世界除了钢筋混凝土将再也看不到一丝绿色。

所以,要让环境变好,就要从小事做起,植树造林、持续水土、防止污染、倡导和树立绿色礼貌意识,为国家的生态环境建设做自我的一点贡献,这样我们每个公民意不容辞的职责。

我相信,在不久的将来,地球会变的十分美丽,到处这样参天大树,绿油油的草地和芳香的鲜花。气候温暖、湿润、空气清新。小鱼儿在清澈的河水里自由自在的游着,小鸟在枝头唱着欢乐的歌,无颜六色的蝴蝶在花丛中飞来飞去。

我认为完美的东西人人都很向往,所以我对地球的未来充满期望,让我们携手共同创造绿色、环保、和谐的人类大家园。

"In the sound of firecrackers, the spring breeze warms Tu su." In the sound

of firecrackers again and again, we have successfully entered 2020, but in this

year, something unexpected happened - the discovery of a new type of coronavirus

in China. Now, more than 10000 people have been infected with the virus, which

has eclipsed Asian lions

But the virus didnt make us shrink back: when we learned that the epidemic

in Wuhan was extremely bad, many angels in white immediately gave up their

holidays and asked for their orders to go to Wuhan and choose to be a rebel.

Zhong Nanshan was one of them. In 2003, he was ordered to fight against SARS, 17

years later. In 2020, he came to the front again to fight against the new type

of pneumonia. He is 84 years old. He should have enjoyed life at home happily,

but he still sticks to the front line of anti epidemic. Like him, other doctors

and nurses give up the time of reunion with their relatives, fight against the

disease, eat the simplest instant noodles, and fall asleep when they are tired

at any place. They are all the most beautiful reversers. As the saying goes, no

matter what time is quiet, only someone is carrying a load.

Besides them, of course, volunteers have also made great contributions.

Many capable people donate money to Wuhan, such as masks and protective

clothing. A large number of rescue teams went to Wuhan to fight against the new

pneumonia. It is said that if one side is in trouble, all sides should support

it. On January 24, a non-woven fabric enterprise in a town had bright lights,

and the enterprise was putting full power into the production of masks. In order

to meet the needs of the epidemic, the workers who should have taken the leave

gave up the Spring Festival holiday and resolutely returned to work. The factory

director said the workers returned to work three times their wages, ensuring

240000 masks a day and providing materials for medical staff.

“那为什么会这样呢?”我问妈妈。妈妈答道:“应该是环境被破坏了吧!”“那是谁破坏了呢?”我追问道。“大多是我们人类吧!”然后,我想了想,又刨根问底地问:“是哪些地方造成的呢?”妈妈说:“是工厂排污水、森林被伐、乱扔垃圾,这些造成的。”

依稀记得以前某一年的一天,奶奶带着我和堂弟去老舅舅家。途中,必须要经过一条河。那条河很长很宽。但是,却很臭,就连河水也是黑色的,在途中。奶奶告诉我们姐弟俩说那条河以前的河水很清,味道也不是那么难闻。还听奶奶说那里有很多条小鱼,他还在那里面捞鱼,游泳呢,可是不知道怎么会演变成那样子可见我们人类当时是怎么对待那条河的。这条河之所以变成现在这个样子,也是由于我们人类破坏生态环境所引起的。我一边去往老舅家,一边在想为什么有关部门不来处理这个问题呢?为什么还要维持现状呢?实在是太不负责任了!

再次去老舅家,在途中必须要经过的那条臭水河居然变得那样清澈,也没有那样难闻的味道了!听奶奶说是因为有关部门把那条河的污染治理了,才会变成现如今的样子。再次想想,他们还是有保护生态环境的意识嘛!可是,我却还是没有看到有小鱼在水里面自由自在地游。看来,我们还是要多多保护生态环境。

现如今,我们能做的,就是不再随便像以前一样什么东西也往河里面扔了。记得有句话几乎人人都知道:保护环境,人人有责。

如果我们不保护生态环境,也会危及我们人类自身的生存。所以我们一定要记住那句我们几乎人人都知道的:保护环境,人人有责。一定要切记,切记。

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。

生活中,垃圾有我们吃剩的果皮壳、纸屑、零食包装袋······

我们吃完这些零食、水果,剩下的垃圾我们会把它丢进垃圾袋里,再把垃圾袋扔近楼下的垃圾箱里,可是大家知道那些垃圾是怎么消失在世界上的?

原来我们会把这些垃圾人往菜园子里一倒,可现在,饮料罐、废纸、玻璃瓶·····这些很难腐烂,但还有种解决方案,那就是重复利用,这些垃圾是无毒无害的,扔掉它就等于扔掉了自己手中的宝贵资源,如果重复使用,污染程度可以大幅下降,而可以腐烂的的垃圾倒在菜园子里可以当肥料,但要注意,重复使用要注意消毒,否则第一次使用留下的病菌就会吸收再我们身体内。

{saxue_innerad}

我会把家里的生活垃圾进行分类,如:家里的厨房垃圾装进一个垃圾袋,生活垃圾装进一个垃圾袋,可以重复使用的垃圾装进一个垃圾袋,楼下的垃圾箱也从原先的一个变成了三个,每个垃圾桶上面都有标志,我把三个垃圾袋按上面的分类丢进不同的垃圾箱。每天早上和晚上都会有专门的回收垃圾的人员来回收的垃圾,他会按照我们分类丢的垃圾来解决。按照这种分类,杭州的空气质量越来越好,污染程度越来越低。

当然,我们也在分类垃圾中遇到了问题,如:在丢垃圾中丢错了垃圾箱:厨房垃圾的垃圾袋破掉了,导致我们在丢垃圾的过程中垃圾袋中的汤汁滴漏在马路上,这点细致问题我们要在丢垃圾前检查一下垃圾袋有没有破,破了的话在套一个垃圾袋,这样就可以避免这样类似的问题。

希望我们能继续保持下去,这样杭州的空气环境可以变得更好!

尊敬的市长伯伯: 您好,非常激动能够给您写

您最近身体是否很健康?工作是否顺利?最近雾霾天气相当严重,您别忘了出门前要及时戴上口罩,以免影响您的身体健康。

为什么最近雾霾天气会如此频繁呢?原因有以下三点:

1.在水平方向静风现象增多。城市里大楼越建越高,阻挡和摩擦作用使风流经城区时明显减弱。静风现象增多,不利于大气中悬浮微粒的扩散稀释,容易在城区和近郊区周边积累。

2.垂直方向上出现逆温。逆温层好比一个锅盖覆盖在城市上空,这种高空的气温比低空气温更高的逆温现象,使得大气层低空的空气垂直运动受到限制,空气中悬浮微粒难以向高空飘散而被阻滞在低空和近地面。

3.空气中悬浮颗粒物的增加。随着城市人口的增长和工业发展、机动车辆猛增,污染物排放和悬浮物大量增加,直接导致了能见度降低。

我想,这三点因素一定就是雾霾产生的原因了。我们小学生不仅要知道雾霾产生的原因,还要注意自我防护,像:雾霾天气少开窗、外出戴口罩、多喝桐桔梗茶、适量补充维生素D、

饮食清淡多喝水等。

让我非常惊讶的是,石家庄在中国空气质量指数排行榜仅仅排名第97位。这令我十分难过,没想到从小生活的城市空气质量那么差!不过更惊讶的是首都北京竟然是排名“倒数第三”,太可怕了。

我认为,地球三大生命要素是:空气、水、土壤。只要这三种少了一种,人类就会灭绝。所以保护环境是非常重要的。环境是人们所在的周围地方与有关事物,一般分为自然环境与人文环境。人文环境保护好了,自然环境就会好。

我们目前是小学生,虽然我们还没有办法保护祖国的环境,但是我们有能力保护好校园的环境、社区的环境以及街道的环境。

从小做起,从我做起。保护环境,人人有责!在这里,我提议:

1. 利用电视台向全国人民发起倡议,在自己生日当天种下一颗树。

2. 提倡汽车单双号出行,可以严重减少尾气排放、

3. 工厂搬出市区。

4. 拆掉小锅炉,采取集中供暖。

希望以上几点能够给您一些建议!

再次祝市长伯伯身体健康、万事如意!

此致

敬礼

绿色,是生命的颜色,是充满活力的颜色,清纯而又可爱。说到这儿,我不禁产生了无限的暇想,仿佛回到了父辈儿时生活的地方,看到了那美丽的景色:在一片丛林中,四周静悄悄的,调皮的风儿不时把树叶吹得“沙沙”作响,如果闭上眼静静地听,就犹如有一位温婉的女子在弹奏着小夜曲,是那么的温柔,令人陶醉。四周飘拂着湿漉漉的露水和着泥土的芳香,这时整个人会觉得神清气爽、心旷神怡。仰起头,和煦的阳光透过树林照射下来,那如同蓝宝石一般的天空飘拂着朵朵白云,小鸟尽情地舒展开翅膀快乐地飞翔。再向深处走去,一条清澈见底的小溪穿林而过,鱼儿自由自在,欢快地玩起了捉迷藏……啊!这儿真的好美好美!“嘟——”一阵刺耳的汽笛声在我耳畔响起,把我从美丽的仙境拉回了现实。我定了定神,这才发现刚刚不过是南柯一梦。来到窗边,朝外眺望:天空灰蒙蒙的,像是笼罩了一层青纱,天空中见不到小鸟灵巧的声影,远处只看得见鳞次栉比的楼房和正在冒烟的工厂。树林变得稀少了,不再是那么生机勃勃、郁郁葱葱的一片,河水变脏了,还不时散发着阵阵恶臭。我呼吸不到那么清新的空气了……我们赖以生存的地球现在怎么会变得这样惨不忍睹?原来,是我们这些地球的主人在作怪。

你瞧,路上的汽车越来越多,在城市几乎每家每户至少一辆,在带给我们快捷方便的生活的同时,它们每天都排放着二氧化碳等有毒有害气体,每年排放的数量多得惊人,使清新的空气变得浑浊了,让蔚蓝的天空变得灰暗了。而有些做恶多端的工厂呢,每天偷排大量的污水流向那清澈的小河,使其变得肮脏,散发着阵阵臭气,人们再也见不着那活泼可爱的小鱼儿。还有些人为了自己的利益,不顾对大自然的危害,直接滥砍滥伐那些参天大树,远远望去,只剩下一个个粗壮的树桩,就像一只只在流着泪的大眼睛……

为了营造安全健康舒适的生存空间,保护人类赖以生存的家园,创造人与自然和谐共处的环境。那么,作为一个小学生,我认为要从自我做起,从身边的小事做起,从现在做起。在日常生活中历行节约,例如:不浪费任何粮食,珍惜水资源,电资源。在植树节栽下一棵小树苗,捡起地上一片纸屑,勇于阻止别人不随地吐痰……只要我们时时刻刻都这么做,我坚信在美好的未来,一定会有一个我们携手共创的绿色、环保、和谐的大家园。

“叮铃叮铃……”我毫不情愿地关上了“值班”的闹钟。“真是的,这么早呢!今天不上学呀!”说着,翻了一个身,又进入了梦乡!

“起床了,起床了!”这是星期五,奶奶又开始叫我起床了!奶奶每天这么辛苦,我也不能赖床呀,接着便立马穿好衣服,一骨碌地溜下了床!

迷迷糊糊地摸索着走进卫生间,习惯性地打开水龙头,拿着牙杯对着出水的口子。半天了,怎么连个滴水的声音都没有呀!我开始清醒了,反反复复地开了又开,咦!怎么还是没有!哦,一定是今天小区停水了。我毫不在意,自言自语道:“反正才这么一天!不管了!”说完就抛下了牙杯,来到了早餐面前。说真的,没有刷牙就吃早饭,感觉还真挺别扭呀!不管了,豁出去了!

“奶奶,这是什么呀!今天早上怎么吃这个呀!我最爱的呢?”我不满地望着早餐。今天的早餐是:面包,牛奶。“今天没有水了,奶奶不能煮稀饭了,先凑合着吃啊!明天奶奶一定给你煮!”换了一顿早餐,我怎么吃都不舒服,仔细瞧瞧时间,糟了,过了半小时了,要迟到了!说完,我连忙背起书包,飞快地跑到了学校。

来到校门前,便听见同学们嘀嘀咕咕地在七嘴八舌:“我家今天没有水了呀!我都不知道怎么洗脸了!真倒霉。”“这么巧,我家也没有水,我连早餐都没有吃呢!”“对呀,厕所的马桶都不能冲呀!”“……”不会吧!大家的家里都停水了,这么邪门。

是不是我们不爱惜水资源,让水资源都消失了。回不来了?我开始反思了。整个上午都没有心思上课,唯独上我最讨厌的科学课,我竟然聚精会神地听着老师讲。明白了不少,更明白到了水的重要性。

放学了,我回到家。还是习惯性地走到厨房,打开水龙头。噢!忘记了,没有水了!真是麻烦,没有水,我要怎么吃东西呀,不洗手吃东西是很脏的。我愤怒极了。漫不经心地打开了电视机。

“据最新消息报道,近几天由于水资源的缺少,可能都没有水,希望人民们注意了!”新闻上的导播正在报导着:“昨日,几位专家检测到。地球上的水资源已经消耗完毕,据说,可能要几年之后……河里,海里,地面上,大多数动物都因没有水奄奄一息。树木的生命也危在旦夕……”我看着这个新闻,整个目瞪口呆--没有水了,还怎么活呀!多少无辜的生命消失了呀!

接着脑海里变冒出了莫名其妙的场面:已经几天没有吃东西的我,脸色苍白。走路都懒地走了。望着窗外,“荒”无人烟。我好渴,好饿。我需要水……

“砰”的一声,我掉下了床。啊!原来是做梦呀,太好了。只是虚惊一场!

这个梦,让我明白了水的珍贵,水是不可缺少的,没有水,哪来的生命。海洋里,所有的动物需要水;小河里,小鱼儿们要靠水生活;森林里,大树小树都需要水资源才可成长;草坪上,鲜花们靠水才可婀娜多姿;而我们人呢,水是我们不可缺少的物质,我们生命的一大部分。

请珍惜水资源吧!为了以后的幸福生活,节约用水吧!
