星期天,我在爸爸的帮助下,上网查了一下西安三月份前半个月的空气质量,一查,让我大吃一惊,我发现其中国重度污染有六天,轻度污染有两天,中度污染有七天。
原来我们生活在这样的环境下,我问爸爸:“雾霾和沙尘对人体有什么危害吗?”爸爸和我查阅了一下网上的资料,原来,雾霾和沙尘的危害非常大,雾霾会导致传染病扩散和多种疾病发生,给人体健康带来较大的危害。沙尘也会危害到人们的身体健康,还给人类出行带来很大的不便。
我又查了一下造成雾霾和沙尘的原因,原来大气空气气压低,空气不流动是主要因素,空气不流动是空气中的微小颗粒聚集在一起,漂浮在空中,由于地面灰尘大,空气温度低,地面的人和车辆是灰尘搅动起来……沙尘是一种风雨沙的相互作用的危害性天气现象,它的形成与地球温室效应、植被破坏、物种灭绝、气候异常等有着不可分割的关系。他还分为沙尘暴、浮尘、强沙尘……
我想我们不应该无节制开采自然资源,不应该随意砍伐树木,有车的人尽量少开车,多做公交车和骑自行车,绿色出行。灯泡尽量用节能灯,少开空调,大家要给街道多洒水。不随地乱扔垃圾,多植树造林,保护我们的地球。
手机是我们随时不可离身的重要物品,但是它的危害又有谁真正的注意过?
第一,手机辐射会危害到人的工作与睡眠。打个比方,你正在开会,忽然一个电话打断了正在讲重点的老总,你觉得他会认为你是一个专注工作的好员工吗?很有可能这个电话会断送了你的前程!很多人会在手机上下载一些游戏,更有的人为了玩那些所谓的游戏熬到3、4点还不睡觉;导致第二天精神不足,你觉得你还有精力做好工作吗?
第二,开车讲电话容易发生事故。据调查发生事故的几率是平常的两倍,这已经危害到了人的生命!人的生命是宝贵的,不该将它置于危险的边缘不是吗?
第三,公共场合打电话干扰了别人。例如,图书馆应该是安安静静的场合,如果这时一个电话铃声响起,你不会觉得不好意思吗?打扰他人学习是可耻的!尤其是在图书馆这种本该安静的地方!以及,课堂上老师正在授课,而你的手机铃声响了,你觉得老师会觉得他受到了他应有的尊重了吗?
第四,真假手机短信的泛滥造成了社会的安定动荡!色情短信的肆意转发,虚假短信的泛滥,造成了青少年的健康威胁以及社会的安定!
第五,手机的不断‘‘升级’’导致了攀比风的加重!明明承受不了还非要打肿脸充胖子!为家庭带了不必要的负担;更有的人为了不属于自己的虚荣卖器官,毁健康来买自己‘‘所需’’的东西!
第六,现在的孩子们都是小小年纪的就玩手机;我有一个5岁的小表妹,一天来我家做客,拿起妈妈的手机就要玩,这是一个习惯还是一种社会风气?引人深思!
以上种种危害都是现实中,我们身边都有的,而我们却不能及时制止!导致越来越多的大人、孩子都带上了眼镜!成了‘‘小四眼’’!
我在这里呼吁‘‘低头族’’:请你们收起手机去看看大自然的美丽,去关怀一下你身边的亲人,去关心一下自己的孩子收获亲情!
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
