城市绿化
On the earth, whether people or animals, no matter how much you if you want to survive, you must absorb a large number of oxygen, emit large amounts of carbon dioxide at the same time. But the earth is originally stored oxygen is limited, and there are not many, so oxygen should run out in N years ago, oxygen and from where to now? That is about to rely on the green plants.
Green plants can be in the sun for photosynthesis, absorb carbon dioxide to produce oxygen. Research shows that: each plants grow a ton, can produce five tons of oxygen. Absorb one ton of carbon dioxide per hectare of forest land every day, 0.735 tons of oxygen; Grass absorbs 0.9 tonnes of carbon dioxide per day per hectare, produce 0.6 tons of oxygen. So do not have oxygen on earth, as long as there is green in the city can also have the fresh air.
Now, to the rising global temperatures are melting glaciers, frequent floods. Especially in large cities, co2 accumulation is more, the temperature is higher, but if more green belts? , according to the determination of summer temperature of asphalt pavement for 49 degrees Celsius, concrete road surface soil as 46 degrees Celsius, the shade under the road surface to 32 degrees Celsius, the shade under the woods to 28 degrees Celsius. Archaism cloud: Lin deep heat. More green belts can reduce the temperature, heat of heatstroke, prevent pavement thermal expansion, damage to the road.
And big cities noise, dust, green belts and can absorb a lot of dust, purify air, reduce noise, to prevent a variety of disease, create a good living environment.
Green benefits more, not just more generally, for their own, in order to the future of the planet, so why not?
绿化好处多，实在是多，这是妇孺皆知的事情，可它究竟多在哪呢?在地球上，无论人或动物，无论你多厉害你要想生存下去就必须吸收大量的氧气，同时放出大量的二氧化碳。可地球是原本储存的氧气是有限的，而且并不多，这样氧气早该在N年前就用光了，现在的氧气又从哪里来呢?那就要靠绿色植物了。
绿色植物可以在阳光下进行光合作用，吸收二氧化碳，产生氧气。研究表明：植物每生长一吨，可产生五吨氧。每公顷林地每天的吸收一吨二氧化碳，产生0.735吨氧气;每公顷草地每天可吸收0.9吨二氧化碳，产生0.6吨氧气。这样一来地球上不就有氧气了，城市中只要有绿化带也可以有清新的空气了。
现在全球气温都在日渐升高，导致冰川溶化，水旱灾害频繁。尤其在大城市中，二氧化碳积聚较多，气温较高，但如果多绿化带又会如何呢?据测定，酷夏沥青路面温度为49摄氏度，混凝土土路面为46摄氏度，林阴下路面为32摄氏度，林阴下绿阴地为28摄氏度。古语亦云：林深不知暑。绿化带多了便可降低温度，消暑纳凉，防中暑，防止路面受热膨胀，损坏路面。
而且城市的噪音大，粉尘多，绿化带又可以吸收大量的粉尘，净化空气，减少噪音，预防了多种疾病，创造良好的生活环境。
绿化好处多，还不是一般的多，为了自己，为了地球的未来，何乐而不为呢?

Don't look at the trees small, small, its role can be big! A tree the effect is not very big, but the role of forest composed of hundreds of trees is big!
We know that the forest can prevent many natural disasters "violation" of our home, and now many cities because of a lack of trees, from the "dust". "mud", etc. The harm of natural disasters. Know these later, such a thought in my heart: I'm going to plant trees, because it to greening the city and prevent natural disasters "infringement". But another kind of idea that I dismissed this idea: my little force, what do for you? I returned a thought: flowers and plants can also be green city! Why can't I kind of flowers and plants? Think of this, haven't. I pulled out my morning glory seeds surviving, put it into the pot.
Ah! A flower is small. Small, but it's like trees, one little effect, but the role of many strains are big. Let's call number: "I make contributions to the sen, a wonderful new home." And action, and let our slogan into reality!
别看树木小，不起眼，它的作用可大着呢!一棵树虽然作用不是很大，但由千百棵树组成的森林的作用可就大了!
我们知道森林可以防止许多自然灾害“侵犯”我们的家园，而现在许多城市由于缺少树木，受到了“沙尘暴”.“泥石流” 等自然灾害的危害。知道了这些后，我的心里产生了这样一种想法：我要去栽种树木，因为这样既能绿化城市又能防止自然灾害的“侵犯”。但另一种想法使我打消了这种念头：我人小力小，帮得上什么忙呢?我又转念一想：花草也能绿化城市呀!我为什么就不能种花草呢?想到此，我拿出我一直没种的.保存至今的牵牛花种子，把它种到了花盆里。
啊!一株花虽小.虽少，但它和树木一样，一株没多大作用，但许多株的作用可就大了。让我们一起喊出口号：“我为创森作贡献，共建美好新家园。”并行动起来，让我们的口号变成现实吧!

People in order to protect the environment the slogans, such as: "nanning is my home, to protect the environment depends on everybody." "Don't step on me, the grass also hurts" "to protect the environment starts from me, starts from everyone, from small start around you.
Then say: why do you want to protect the environment? Because people don't know to use a lot of cars to protect the environment, too much exhaust damage the ozone layer, the arctic ice will melt, water will cover the whole earth. So, from now on we will protect the environment, save electricity, can 秏 buyers shop to buy a level, or the secondary energy consumption, air conditioning and the snow is not produce ozone.

你知道3月12日是什么节吗?对了，就是植树节。每到这一天，就有很多人去义务植树，为的就是保持生态平衡。人们渐渐有了环保意识，上街买东西都用用布袋装，吃东西不用一次性筷子，上班工作大多数都使用单车或电动车也乘公车，乘公车可减少车尾气的排放。人们为了保护环境插了标语，比如：“南宁是我家，保护环境靠大家。”“别踩我，小草也会疼”“保护环境从我做起，从每个人做起，从身边小事做起。
接下来说一说为什么要保护环境?因为以前人们不懂得保护环境大量使用汽车，造成太多尾气排放破坏了臭氧层，那么北极的冰就会融化，水就会淹没整个地球。所以，从现在开始我们就要保护环境，节约用电，买家店买一级能秏的，或二级能耗，空调加的也是不生产臭氧的雪种。以后，我们要多坐电动车，多坐单车，少坐汽车，减少对地球的危害。
保护环境，从我做起。
