一次性筷子的坏处-从健康与环保的角度看起

全文共 2093 字

+ 加入清单

筷子是中国人的主要餐具,是中国饮食文化的重要体现,但近年来,当古老的传统遇到现代社会“快速、便捷、卫生”的价值观时,国人对这项餐具的耗费让人触目惊心。随着人们的生活节奏大大加快,忙着上班,忙着上学,忙着赚钱,忙着休闲……在忙碌中,“一次性”用品越来越受到青睐。在中国大多数的餐馆,无论档次高低,一次性筷子早已成了必不可少的餐具。一次性筷子又称“卫生筷”、“方便筷”,是人类社会生活节奏加快和社会服务发到一定阶段的产物,曾被视为一种文明标志。然而,现实表明,其所谓“卫生”和“方便”不过是人们一种虚幻的心理期望,它的使用与“折枝为筷”本质相同,与每餐清洗消毒、不需要众多生产基地和繁琐运送过程的多次筷子比,即不卫生也不方便。它的生产,是一种野蛮的掠夺行为,它的储运中伴随着难于避免的污染,而其作用,显然是不清洁和浪费。一次性筷子给我们带来的无穷后患:1, 一次性筷子给人们的生活的确带来方便,然而,从环保角度看,在这方便、快捷的背后是大量资源的浪费与垃圾的堆积。据统计,中国每年消耗一次性木筷子800亿双,首尾相接,可以从地球往返月球21次, 可以铺满363个天安门广场。每回收3双一次性筷子,就可以生产一张A4纸。按50人的公司的用纸量计算,做出的纸大概可以使用55万年。每年为生产一次性筷子要耗费木材166万立方米,需要砍伐大约2500万棵大树,减少森林面积200万立方米。而一棵生长了20年的大树,仅能制成3000-4000双筷子。山西首府太原市有近万家大大小小的饭店,以半数使用一次木筷且平均每天每个饭店接待100位客人的保守估算,全市一天也要用掉50万双一次性木筷!

就是说,仅太原一个城市,人们每天就餐的同时也吞噬下相等于125至170棵大树!

以中国宽广的森林定义和世界首位的人工林面积,其森林覆盖率也仅为18。21%,居世界第130位。当中还存在森林质量不高,如林种单一、树龄低等问题。中国长期以来的农业、经济发展,人口持续增加已对中国的森林造成了无法弥补的破坏。因为十三亿人每日就餐的需要也要吃进去那么多的树木,这种不必要的浪费既让人痛心又无比荒唐。在中国,一次性筷子在使用后是不进行回收的。这与一次性筷子在日本被回收造纸的情况差别很大。中国政府也已经认识到相关的木材浪费问题。2004年取消一次性木筷出口退税(13%)并征收17%的增值税;2006年4月1日对一次性筷子增收5%消费税;2006年11月1日又征收10%出口关税。一次性筷子大概已成为我国流转税负最重的农林产品之一。一次性筷子还有可能产生“温室效应”。因为恶性循环的关系,树少了,二氧化碳会增多,大气层会加厚,热量难以散开,就产生了“温室效应”。2,从健康角度来看,选择一次性筷子就等于放弃健康。正规的一次性筷子所用的原料都是质地比较好的木材,不需要特殊加工。但是现在很多小作坊为了降低成本,使用的都是劣质木材,看上去“肤色”较黑,这不太美的颜色当然无法受到食用者的青睐。因此,小作坊生产者经加工处理后的一次性筷子,马上就会“改头换面”,堂而皇之地登上了人们的餐桌。一次性筷子有两种制作方法,固态的制作方式是通过硫磺的熏蒸漂白。经过硫磺气体漂白的筷子,其二氧化硫会严重超标,而二氧化硫的特性之一就是遇冷会凝固。因此,人们用这种筷子进餐时,二氧化硫随着空气的流动很容易凝固至呼吸道,咳嗽、哮喘等呼吸道疾病便随之而来。除此以外,硫磺中含有重金属,例如:铅、汞等……重金属在人体内部是可以堆积的,长时间的累积会造成铅中毒或汞中毒。 液态加工的筷子的方法是通过氯气或者双氧水漂白,特别是氯气,它不仅容易造成人体内的胆结石,而且含有曾经让人们谈之色变的二恶英。至于竹筷子,为了去除筷子的毛刺,令其看起来光滑。白皙,制作者将其放入滑石粉中,通过摩擦对筷子进行加工。但滑石粉容易增加人体患胆结石的机率。尽管不正规厂家生产的一次性筷子危害性很大,但到目前为止,我国对一次性筷子仍没有出台具体的卫生检验的标准。因此,一次性筷子隐藏三大危害: 损害呼吸功能:一次性筷子制作过程中须经过硫磺熏蒸,所以在使用过程中遇热会释放SO2,侵蚀呼吸黏膜;损害消化功能:一次性筷子在制作过程中用双氧水漂白,双氧水具有强烈的腐蚀性,对口腔、食道,甚至肠胃造成腐蚀,打磨过程中使用滑石粉,消除不干净,在人体内慢慢累积,会使人患上胆结石; 病菌感染:经过消毒的一次性筷子保质期最长为4个月,一旦过了保质期则很可能带上黄色葡萄菌。大肠杆菌及肝炎等。 3,从人类心理的角度来看,长期使用一次性的用品不利于青少年好心态的养成。现在不仅有一次性碗筷,还有一次性饮料杯、一次性内衣、一次性相机等等,一次性的用品队列越来越长,使用这些一次性用品的另一个危害就是让我们养成了用了就扔的坏习惯,这绝对是不利用青少年心态健康成长的,这也是与倡导永续地球相违背的。这几年自备环保筷的观念也渐渐在国内传播开来。国内许多城市就有由许多志愿者发动的“筷行动“,除了宣导民众自行携带环保筷,也开始倡议餐饮业者提供环保消毒筷,以达到环保、健康的目的。让我们也加入他们的行列吧!

在我们生活的现实世界以外,有一个神奇的网络世界,你知道吗?这个世界可是太有趣了。不信你就随着我的笔墨到网络世界去转一转。

应该承认,网络上也有许多不好的东西。有的人通过网络发布一些黄色、淫秽等不健康的东西,诱惑青少年;有的人在网上设置病毒程序,使许多人的电脑资料丢失、电脑死机。还有的人通过网络散布反动的东西,就象邪教“xx”一样,它们通过网络发布信息,鼓动它的信徒聚众闹事,同政府相对抗。这些都是我们这些小朋友需要引起警觉的,我们现在还缺少分辨是非的能力,对这些东西有时候还可能感到好奇,这就需要我们多向大人们请教、学习,知道那些东西是我们应该看的,那些是需要回避的。有的小朋友因为玩网上游戏,耽误了学习,这都是需要我们每一个小朋友引起警觉的。

总之,网络对我们的影响是巨大的。我们今天生活的时代就是一个网络的时代,网络影响着我们的生活,改变着人们对世界的看法。作为新时代的少年,必须学会使用网络,使网络能够为我们的学习服务,同时要避免迷恋于网络。

qq的好处与坏处

qq,一说到这两个字母,大概我们的脑海里面就会出现一只可爱的小企鹅在晃来晃去。在信息时代的今天,功能强大、用途广泛的qq,已逐渐普及到人们的生活和工作中,有些人甚至以离不开qq。

在当今的时代中,人们的沟通方式太多了,不在局限于面对面的聊天,qq就是一个很好的工具,它可以让你和朋友聊天,当然如果你想看到画面和听到声音,可以通过视频功能来实现,又或是你的朋友不在线,你也可以给他(她)留言,还可以发送离线文件。她还可以让我们认识五彩缤纷的世界。

qq带来的不仅有好处,而且也有坏处。也有很多人被qq所吸引了。例如,打牌,打麻将。妈妈给我讲过一个故事,故事是这样的:一天清晨,当人们从睡梦中醒来,面对新的一天和新的生活时,一个坐在电脑前玩了一整夜qq游戏的少年也想站起来活动一下筋骨,他刚从椅子上站起来,就突然栽倒了,在一旁的伙伴很快地去扶他,却怎么也扶不起来,一个年轻的生命就这样永远地消逝了。我问妈妈这个少年为什么会突然死亡呢?妈妈回答说:是长时间上网加之无充足的食物能量补给引起的极度疲劳造成的死亡。我感到很震惊,我想为了自己的身体健康,我以后一定要严格控制自己上网的时间和次数,不能长时间的玩游戏、看电视等。

有一次,我还问过邻居家的医生:长时间上网对身体有什么不好的影响?医生告诉我,长时间盯着电脑屏幕容易造成头痛、视力下降和免疫系统受损;长时间敲打键盘,会对手指、手腕、肩部、颈部造成损伤;长时间坐着,可能造成腰部的不适。另外,电脑辐射也是不能忽视的。

随着社会的不断发展,网络在我们的生活中已经变得不可或缺,qq功能强大、用途广泛,我们小学生们都在使用它,希望大家能用qq多做有益的事情,取之长,避之短,让qq和网络真正为我们的生活和学习服务。

大家都有qq,我们都用它来聊天,玩游戏……可我对qq有很多笑容和泪水,下面就让我讲一讲吧!

故事发生在二年级的时候,那时候,全班基本上都有qq,就我没有,我就请求爸爸给我申请一个,可爸爸却说,玩这个不仅对学习不好,还毁眼睛,就没答应。我那么的恳请爸爸,爸爸却说:“等你考试考了双百分,就给你申请一个。”听了这句话,我从那时候起,就一直认真复习,认真考试,终于期末考试时,取得了双百分的好成绩。爸爸就高兴地申请了一个,昵称叫:雪精灵。那一天,我笑得是那么开心。

从我有了qq后,以后什么不会的题呀和小伙伴们讨论作文呀,都可以通过聊天解决,周末写完作业后很无聊,小伙伴们也不在线,就可以玩一玩上面的游戏,不过,也要有时间控制哟!

但是,那一天,下午放了学后回到家,写完作业后就去玩qq了,爸爸妈妈看到了,大声叫道:“冯欣,写完作业了?就去玩电脑?”我随意地说了一句:“写完了。”他们就没再吭声,过了一会儿,爸爸又叫道:“冯欣,吃饭了,别玩了。”我却说了一句“知道了。”可还是一直在玩。爸爸过去就把电脑给关了,严肃地说:“叫你吃饭了没有,整天就知道玩,看以后你的学习怎么办?”我哇一地一声爬在床上哭了起来,泪水浸湿了一大片被子。就这样,我哭着进入了梦乡。

还有那一次,语文作业上有一项是做一张老师发的卷子,可是卷子上有很多题都不太会,有的都不理解什么意思。于是就通过qq上面的聊天发给我的好友,就这样,我们通过聊天模式讨论,我就把所有不会的题都写出来了,不太理解的也懂是什么意思了。那一天,我笑得好开心,心情大好。

通过这几件事情,我的感悟是:qq原是一个方便的项目,我们要合理安排。不要让它变成不好的。

Oh! What you said is right. It has lots of advantages. But do you know the internet rumors. I think if everyone can publish news on the internet .there will be more rumors. Let me introduce the harm about it to you.The spread of the Internet rumors should be based on three conditions: Firstly, the Internet has the widespread availability and convenience. Compared with other channels of transmission, the Internet has fast speed and wide extent. And spreader can lower the cost of distributing rumors. Secondly, there are many ill-intentioned people existing on the Internet, as snakes in the grass. These people are always hopping to draw others attention or even disturb public orders via rumors. They are selfish. Thirdly, the anonymity of the Internet enables some spreaders to avoid being punished for their evildoings.

So we need to limit some speaking rights of people to avoid troubles for society.

Staying up late will be detrimental to human health, because the adrenal cortex hormone and growth hormone are all secreted during the night when people are sleeping. The former is secreted before dawn, which can promote the metabolism of carbohydrate in human body, and protect the development of muscle; while the latter is produced only after sleep, which can not only promote the growth and development of young people, but also can delay the aging process of the elderly. As a result, staying up late will cause a variety of harms to human body.

Do you always work or study until midnight?

Do you often hang out or spend much time in pubs at late night?

If you answered yes to either of these questions, you are unfortunately one of the large groups of people who always stay up late. Because of the fierce competition in the society, it seems that everyone has endless work to do and twenty-four hours per day is not enough. Therefore, an increasing number of people stay up late in order to finish the mountainous work. Besides, lots of young people enjoy entertaining at late night. However, many of them are still not aware of the bad effects of staying up late. In fact, it does severe harm to us in three aspects, namely physical health, work efficiency and mental stress.

In the first place, staying up late badly impacts on our physical health condition. The human adrenal cortex hormone and growth hormone, which are vital substances for human body, only secrete at night. The former secretes before the dawn facilitating the carbohydrate metabolism and protecting the development of muscle function. The latter only secretes after sleeping. It can improve the growth of the young and slow down the aging of the elderly. However, if people often stay up late, the secretion of these two substances will be gravely impacted. Finally, our health condition will be degraded. It can cause a variety of harms to human body. Normally, frequent staying up late will lead to fatigue and degraded immunity. People may easily get sick when the weather gets a little bit colder or hotter. In addition, it can also cause headache. People may feel heavy in the brain and dizzy for a whole day. Besides, the fertility of both male and female will be impacted. For women, it will affect the secretion of female hormones and the quality of ova. It also tends to affect the menstrual cycle. For men, both the quality and quantity of sperm will be impacted. What is more, staying up late can also damage people’s eyesight, skin and memory capacity, and cause black eyes as well.

Furthermore, it negatively impacts on the work efficiency. On the one hand, owing to the discomfort of your health as mentioned above, you may feel distracted from the work. On the other hand, because of the decrease of the memory capacity, your work efficiency will be lower, which means that you may not complete the things as you want. Assume that you are a university student and you plan to review for your psychology examination next week after tomorrow’s class. Nevertheless, you stayed up late yesterday for some reason. Therefore, you probably be late for tomorrow’s class or even skip it. Thus, you must find other time to compensate for it. Afterwards, when preparing your examination, you may feel headache and cannot concentrate on it, thus having difficulty memorizing and understanding the psychological terms and principles. Therefore, your schedule for reviewing chapter 2 and chapter3 will be changed. You can only review chapter 2 and may not finish chapter 3. However, in order to finish reviewing on time, you are more than likely to stay up late again. Then, you will be in the vicious cycle and your work efficiency will be lower and lower.

What is also noticeable is that staying up late can bring about mental stress. Since your work efficiency is lower, you probably doubt yourself whether you are a capable person or not. You may think you are not so smart as others and even fear yourself that you can hardly get a good grade in your psychology examination, which makes you feel more anxious and upset. Besides, if you frequently stay up late, you definitely look tired and in low spirits. Therefore, when working on a group project, maybe nobody wants to be in the same group with you, a low-efficient and anxious person. Thus, you will feel separated from others, which possibly makes you more stressed and upset.

In conclusion, although we have a lot of work to do and various activities to participate in, staying up late is by no means a good choice for us. It badly impacts on our physical health, lowers our work efficiency and makes us stressed and anxious. Faced with too much work, we should make good arrangements in advance and maintain a healthy lifestyle.

随着科学技术的进步,互联网的发展速度越来越快,网上的信息也越来越丰富。对于上网的态度我是既赞成上网又反对上网。我赞成上网的原因是因为网上的资源很丰富我们可以利用网络找到与我们学习工作相关的资料,还可以在网上进行购物、看电影、听歌等等,为我们的生活带来无穷的快乐。

记得有一次我拿着刚刚买的电脑学习机,想去下载一些资料,于是,我拿着学习机来到舅舅家里用舅舅的电脑通过互联网从网站上下载到了我要下载的资料。听舅舅说他用QQ在网上结交了很多网友。

我反对上网的原因是因为现在互联网上的信息很丰富也很复杂,有许多的不良信息,而我们大部分是未成年人,很容易受到那些不良信息的诱惑,所以我们在上网的时候应该加强自己的自律能力,不要浏览不健康的网站!

网络是把双刃剑,我们应该利用它有利的一面,避免它不利的一面。让互联网为我们的学习和生活服务,使我们的学习和生活变得更加精彩!

陀螺的坏处小学生作文

陀螺虽然很好玩,可是也有坏处,它不但有坏处,而且还非常得贵,一个中等大小都要45-50块钱,一个比较好的大的都要80-90块钱。

陀螺的坏处有:陀螺的攻击环会把手给割伤,还有时会引起误会。比如:一个人不小心踢了别人的陀螺,然后那个人就会踹上一脚还击,然后两个人就会为了自己心爱的陀螺争吵打架。我们班的那些人几乎都有这个坏毛病。

星期四的时候,夏子乔借给我一个陀螺,我和黄鸿杰PK。我用的陀螺要撞到墙了,我用绳子想移动它的方向,突然黄鸿杰的陀螺冲了过来,把我的手给割了一下,因为他的陀螺攻击环太锋利,把我的手给割出了一条伤痕,先是有点痛,然后就是流血,然后张怡叫我去洗手。她拿来绷带把我的手包扎起来。

上课的时候,我解开绷带,绷带上有一堆血,看来割得不轻。手还是那么痛。

回到辅导班,手才不那么痛了,我发现伤口结了一个小疤,陀螺真是危险啊!

老师,请你不要让我们班玩那些危险的陀螺,割到人是非常痛的。要玩也可以,就是要小心一点,玩的时候要注意安全,玩的空间要小一点,因为每一次上课都会被挡住, 走中间又怕碰到他们的陀螺,然后被他们说,真是为难啊!

我们出生一个互联网的世界,所有人的生活逐渐碎片化了。生活像是在排队,而着排队的目的就是——死亡,有人无聊唱了一首歌成了歌唱家,有人无聊画了一副画成了画家。而这互联网像是插队,许多人太依赖互联网,其实离死亡更进一步了。

当然互联网也有很大的优点,比如购物,以前没有互联网的时候,商家和消费者之间的交易信息不对称,有了互联网以后,商家通过互联网的大数据了解客户的需求,消费者通过互联网了解的更多的商品和价格信息。也比如逛街,以前没有互联网的时候,出门逛街要不带着厚厚的一叠钱,要不带着五彩缤纷的银行卡,有了互联网,我们只要带个手机,用上面的支付宝,微信支付就可以了。

在古代时,人们用飞鸽传书、驿站、烽火塔来传递信息,后来19世纪,人们开始用电话来传递信息,现在只有“滴滴”三秒搞定。

但是,本是天使的互联网用多了就会成为黑暗的魔鬼吞噬你的生命,太依赖互联网的人,一天要用至少6小时以上,占一天的四分之一时间,占醒着的七分之三!所以不要过度的使用互联网。

互联网有好有坏,我们应该合理的用好互联网,不要沉迷其中!沉迷虚拟世界!为了你的生命,请少用互联网吧!

碎片化带来的坏处作文1000字

如今的时代是碎片化的时代,如今的生活是碎片化的生活。一切的一切都被冠以碎片化。

的确,从字面上看,我们的一切确实被碎片化了。诸如上学在车上,我们拿出碎片化的工具——-手机,上面镶嵌着玲琅满目的软件,我可能会在QQ与微信两大主战场之间来回奔波,在歇战期打开知乎与阅读软件读上片刻书,最后翻一翻日历,看一下今天要完成的事。可以说,我们有限的时间被进一步拆分,并竭尽所能使这每一个部分都充满了意义。

但从实质来说,我并不认为我们的生活是被碎片化了,而是一种充满节奏韵律的连贯。它将来给我们更多样的生活,并且它的到来也是必然的。

如今的社会是比原来发达太多的社会,如今的社会也是更加快速的社会。但唯有时间是不变的。一切行为都会产生信息,在这个更加快速而时间永恒的时代,这一切的结果便是我们每时每刻将面对并处理更多的信息。为此,人们创造了飞机,汽车等交通工具,人们还创造了信件,邮箱,电话。这一切的重要驱动力便是人们对更快节奏生活的适应。因而,碎片化是可喜可贺的,也是人类进步的必然起因与必然结果。同时,对于更早时代的人们来说,后时代人们的生活永远是碎片化的,但其实质也只是信息量的骤增与人们的不适应,将这种代表进步的快速化命名为碎片化。

而在碎片化带给生活的实际影响方面,诚然,起初的不适应会让人们措手不及,打乱了计划,怠慢了生活。许多人为此而焦躁不安,指出碎片化分散了注意力,使人们在做每一件事时都不能全神贯注,最终效果不佳。也有人指出如今碎片化的生活极大地影响了人们的生活质量,无暇分心他顾,去寻求属于自己的生活。为此,城市中在快节奏的“沉闷”活出现了倡导慢节奏的声音。在因为快节奏需求催生的网商书店的攻势下急剧锐减的实体书店又因此焕发了第二春,成为了以“慢节奏”体验经营为特色的新兴书店。顺应快节奏需求的移动单车也福至心灵般地给自行车行业开辟了一片最亮丽的广阔天地。

因此,碎片化初期的不适应仅为阵痛,之后的世界也将变得更加广阔而多元。碎片化并不是人类社会发展的毒瘤,而是进步的缘起与永恒的伴随者。碎片化也并不是分散注意力,降低生活质量的毒药,而是一种极有节奏韵律,使人们更能培养自身注意力的良方。碎片化的生活也并不是消亡与毁灭,而是给我们已然平淡的生活注入新的活力,使我们拥有更多的选择。

遇上碎片化,为何不真心展露自己的笑颜?

手机的好处和坏处作文500字

全文共 504 字

+ 加入清单

手机好处也有坏处!就像天使与恶魔!是统一体。

手机有许多的坏处。生活中有不少。我妈妈吧,就很爱玩手机,不分日夜。早上5点妈妈本来还在睡觉,可是我发现她手上多了一个麦芒手机。妈妈入迷地看着,什么淘宝抢购什么的。我爸爸也是最爱手机,爱打QQ斗地主。我也爱发博客,我同学聊聊微信QQ。妈妈和爸爸还喜欢看书和小说,有时连上厕所都在看,有时晚上12点了还在玩手机。真是“精神可嘉”呀!

还有一次我要去上学,在一个十字路口,正好是绿灯,可是妈妈包里的电话却响了起来。妈妈接起电话:“喂,你好,嗯,好的好的……”5分钟过去了,我急的叫起来,可是这时妈妈又听到了微信的声音,于是又是不停的发微信。好不容易发好了,可是这时候马路上的绿灯又转红灯了。我急的快要哭出来了,在这点上我爸爸还是做的很好的。

手机当然也有不少好处。它有着前所未有的方便,和朋友联系只要按下语音就可以了,有任何问题疑问只要百度一下就可以了,另外购物也方便了不少,不用外出购买,只要在家里点点手机就行了。另外还有外卖,只要在家里等着,东西就送到了你的身边。

手机就像天使又像恶魔!我们要正确对待使用手机,要使用它的好处而不是它的坏处。那它会给人们带来更多的方便!
