Protecting the environment is not a thing, we need to insist every day, and anywhere to put into action. As long as we each action, and we will be able to save our survival homeland - the earth.
Save electricity, protect resources, reduce pollution.
Electricity is our each pupil come into contact with every day, and also we learn every day life is inseparable from, but now consumes. When electricity so every move, will start from saving.
In our country, power generation mainly rely on coal, and coal is limited on the earth. According to the present rate of consumption of global consumption of coal will be 250 years. By then, we will have no any coal left to our offspring.
Save electricity, is to save coal, is also directly contribute to reduce air pollution. Because of acid rain is formed due to coal burning, it can strong corrosion buildings, and can make the water and soil acidification, lead to food production, vegetation fish died. According to the calculation, only in our country southwest, south China economic damage due to acid rain was 14 billion yuan a year.
Save electricity, to slow down global warming. Due to large amounts of coal combustion emissions of carbon dioxide, as a cover to block the heat of the ground outside sends out to the sky, and the greenhouse effect, if the earth's temperature rise, will cause drought or flood, will cause the melting ice. If the earth on the iceberg melt, lower altitude countries and islands will disappear.
Live in today, we are bound to enter the next century, many of them are for global warming, and fragile. German vowed to let 192 schools of 192 children in the community in which he lived the harmful gas of greenhouse effect reduced by 10%. They put on energy saving lamps, refused to use air conditioning, abandoned cars, choose the bicycle. After seven months of hard work, they have reached the goal.
Twinkling of an eye, we have run into beautiful June again, it's tree planting and afforestation opportunity of the country, in order to create a good green home, protect the ecological environment, I suggest the students:
Love nature, love flowers and plants trees, protection of endangered species, plant trees to protect the green activities.
Actively promote environmental protection, the environmental protection consciousness to bring home.
保護(hù)環(huán)境不是一時(shí)的事,需要我們每天堅(jiān)持,并隨時(shí)隨地付諸實(shí)際行動(dòng)。只要我們每個(gè)人都行動(dòng)起來(lái),就一定能拯救我們生存的家園——地球。
節(jié)約用電,保護(hù)資源,減少污染。
電是我們每一位小學(xué)生每天都會(huì)接觸到的,也是我們每天學(xué)習(xí)生活都離不開(kāi)的,但是現(xiàn)在消耗驚人。所以用電時(shí)的一舉一動(dòng),都要從節(jié)約出發(fā)。
在我國(guó),發(fā)電主要靠燃煤,而地球上的煤是有限的。按現(xiàn)在的耗用速度,全球的煤將在250年內(nèi)消耗。到那之后,我們將無(wú)任何煤留給我們的后代。
節(jié)約用電,就是節(jié)約煤,也更是直接為減少大氣污染做貢獻(xiàn)。因?yàn)樗嵊晔且蛎禾咳紵纬傻,它能?qiáng)烈的腐蝕建筑物,并能使土壤和水質(zhì)酸化,導(dǎo)致糧食減產(chǎn),草木魚(yú)蝦死亡。據(jù)計(jì)算,我國(guó)僅西南,華南酸雨造成的經(jīng)濟(jì)損失,每年就達(dá)140億萬(wàn)元。
節(jié)約用電,能夠減緩地球變暖。由于煤碳燃燒排放的大量二氧化碳,像一個(gè)罩子一樣阻隔地面的熱量向天空外散發(fā),產(chǎn)生了溫室效應(yīng),如果地球溫度升高,會(huì)引起干旱或洪水,還會(huì)使冰山融化。如果地球上的冰山全部融化,海拔較低的國(guó)家和島嶼就會(huì)消失。
生活在今天的我們,是肯定要邁入下一個(gè)世紀(jì)的,他們很多都為全球日益變暖而脆弱。德國(guó)192所學(xué)校的萬(wàn)兒童發(fā)誓要讓自己所居住的社區(qū)中造成溫室效應(yīng)的有害氣體減少10%。他們換上節(jié)能燈,拒絕用空調(diào),放棄用汽車,選用自行車。經(jīng)過(guò)7個(gè)月的努力,他們已達(dá)到了目標(biāo)。
轉(zhuǎn)眼間,我們又快要進(jìn)入美麗的六月了,這是植樹(shù)造林,綠化國(guó)家的大好時(shí)機(jī),為了創(chuàng)造良好的綠色家園,保護(hù)好生態(tài)環(huán)境,我建議同學(xué)們:
熱愛(ài)大自然,愛(ài)護(hù)花草樹(shù)木,保護(hù)珍惜動(dòng)物,開(kāi)展植樹(shù)護(hù)綠活動(dòng)。
積極宣傳環(huán)保,把環(huán)保意識(shí)帶給千家萬(wàn)戶。
