小學六年級英語作文范文：全球變暖
I often see on television, network is now the holes of the earth has been destroyed by human, if we are in different heart to protect it, the destruction of the earth will be completely in the near future. Faster and faster, with the development of human science and technology science and the negative effect gradually manifested, then let me give you a few examples to illustrate why experts predicted that the earth will be gone after so many years.
First of all, global warming is one example, soak in the hot weather in summer air conditioning becomes a new "hobby", but what do people ever thought of air conditioning can bring negative effect? Gas air conditioning to contain large amounts of methane, to the outside is the leading cause of global warming gases, methane and air conditioning will waste a lot of electricity, so try to avoid using the air conditioning or appropriate use.
Another reason is that carbon dioxide, automobile exhaust and factory waste gas containing a large amount of carbon dioxide, and carbon dioxide are most likely to lead to global warming. Cars now, too much exhaust serious affect our nong cough, throat inflammation... . According to concerning sectional statistic China's per capita emissions of carbon dioxide emissions every year 2. 51 tons a year! The changes in the harsh environment around us.
More important reason is that: reduce forest, farmland, water damage and serious water pollution, fresh water supply is a problem, many parts of the draft has become a big problem. Now countries are massive effort, demanding, and costs "of the south-north water diversion project".
In order to save the planet, people all over the world should be: don't open air conditioning, use recycled environmental protection bags, don't use plastic bags, take the bus, don't throw waste batteries... Such as the dribs and drabs in life. In fact, environmental protection is not difficult, as long as you support is the best gift you give earth environmental protection, take action, this is a powerful force!
我在電視上、網(wǎng)絡上經�？吹浆F(xiàn)在的地球已經被人類破壞的千瘡百孔，如果我們在不同心協(xié)力的保護它，地球將在不久的將來徹底的毀滅。隨著人類科技的發(fā)展越來越快，科學隨之產生的負面影響逐漸體現(xiàn)出來，下面我就給大家舉幾個例子來說明為什么專家會預言地球將在多年后不復存在。
首先全球變暖就是一個例子，天氣炎熱在酷暑里泡空調成為一項新的“業(yè)余愛好”，但人們可曾想過空調會帶來什么負面影響呢?空調排出的氣體中含有大量的甲烷，輸送到外面甲烷也是導致全球變暖的氣體，同時空調還會浪費掉大量的電力資源，所以要盡量避免使用空調或適當使用即可。
另一個原因就是：二氧化碳，汽車尾氣與工廠廢氣中含有大量二氧化碳，而二氧化碳最可能導致全球變暖�，F(xiàn)在汽車逐漸增多，太多的尾氣嚴重影響著我們咳嗽、喉噥發(fā)炎……。據(jù)有關部門統(tǒng)計中國每年的二氧化碳排放量人均排放量達到2。51噸每年!我們周圍的環(huán)境在惡劣的變化。
更重要的原因就是：森林減少，農田減少，水資源破壞，水污染嚴重，新鮮的淡水供應成了問題，許多地方吃水已經成了一大問題�，F(xiàn)在國家也在大規(guī)模的搞費力，費神，又費財?shù)?ldquo;南水北調的工程”。
為了拯救地球，全世界的人們都應該做到：不開空調，使用回收環(huán)保紙袋，不用塑料袋，乘坐公交車，廢舊電池不要亂扔……等生活中的點點滴滴。其實環(huán)保并不難，只要大家支持環(huán)保就是你給地球最好的禮物，行動起來吧，這就是一股強大的力量!
