描寫霧霾的危害英語作文100字

　　Everybody watches the winter haze weather, the fog haze harm is bigger, there are several city already in it, so we should strengthen the environmental management efforts, no longer let haze weather.

　　Must have a lot of people know the cause of the haze, fog, fog and haze, of course, is made of, fog is the main cause of a large number of small water droplets or ice crystals suspended in the ground the air system, composed of aerosols is a product of condensed water in the air near the ground layer. Fog is mainly will reduce visibility, can cause traffic hidden trouble, but not harm to people.

　　Haze is made up of the dust in the air, harmful material such as sulfuric acid, nitric acid, it can make the atmospheric turbidity, blurry vision and leads to reduced visibility, and can cause great harm to human body. So fog and haze two brothers together, this irrelevant to unprecedented damage caused by the atmosphere, some city's air quality has come to the point where moderate pollution, some cities has reached high levels of pollution, more terrible.

　　The dangers of smog is quite large, it will for highway, railway, aviation, power supply system, affect crop growth. Also easy to cause the spread of infectious diseases and a variety of diseases.

　　Our precautions should be in place, in haze weather, we should stop morning exercise and outdoor activities. This just isn't good enough, I think this is the main reason of the bad weather in automobile exhaust emissions and industrial emissions, so the country should policy instructions as soon as possible to manage and control the harmful gas emissions, more tree and grass planting, purify our environment. I think, if everyone is mobilized, haze weather should flew away.

　　In a word, I hope you can take action, a variety of grass flowers, how to protect the environment, for our future generations to build a green, natural environment.

　　這個冬天霧霾天氣備受大家的關(guān)注，霧霾危害較大，有好幾個城市已經(jīng)中了它的招，所以我們應(yīng)該增強(qiáng)環(huán)境管理的力度，不再讓霧霾天氣橫行。

　　霧霾的成因想必有不少人知道，霧霾嗎，當(dāng)然是由霧和霾組成的，霧的主要成因是大量懸浮在地面空氣中的微小水滴或冰晶組成的氣溶膠系統(tǒng)，是近地面層空氣中水凝結(jié)的產(chǎn)物。霧主要會使能見度降低，會造成交通隱患，但對人的危害不大。

　　霾是由空氣中的灰塵、硫酸、硝酸等有害物質(zhì)組成，它會使大氣渾濁，視野模糊并導(dǎo)致能見度降低，并且會對人體造成較大的傷害。這樣一來霧和霾兩個本不相干的兄弟聚到了一起，對大氣造成空前的破壞，有些城市的空氣質(zhì)量已經(jīng)到了中度污染的地步，更有些城市已經(jīng)達(dá)到了重度污染，非常可怕。

　　霧霾的危害相當(dāng)大，它會對公路、鐵路、航空、供電系統(tǒng)、農(nóng)作物生長造成影響。還易導(dǎo)致傳染病擴(kuò)散和多種疾病發(fā)生。危害人的健康。并且會導(dǎo)致空氣中污染物不易擴(kuò)散，增強(qiáng)有害物質(zhì)的毒性，嚴(yán)重的，還可能會導(dǎo)致毒霧發(fā)生。并且會對人造成巨大傷害，特別是對呼吸系統(tǒng)影響很大。有報道稱，這個冬天呼吸系統(tǒng)發(fā)病的人比上個冬天增加了%30---%40。這是一個多么驚人的數(shù)字，值得我們深思。所以防治霧霾天氣刻不容緩。

　　我們的防范措施應(yīng)該到位，在霧霾天氣時，我們應(yīng)該停止晨練和戶外運動。只是這樣還不夠，我認(rèn)為造成這種惡劣天氣的主要原因是汽車尾氣的排放和工業(yè)生產(chǎn)廢氣的排放，所以國家應(yīng)該盡快下達(dá)政策來管理和控制有害氣體的排放，多植樹種草，凈化我們的環(huán)境。我想，如果大家都動員起來，霧霾天氣就應(yīng)該灰溜溜的逃跑了吧。

　　總之，我希望大家可以行動起來，多種草種花，多保護(hù)環(huán)境，為我們的子孫后代營造一個綠色，天然的環(huán)境。
