he waste products released from artificial substances, industrialproduction and increased consumption of goods. Bedsides, the use of chemical substancesin agriculture also causes environmental pollution. Look at the sky, you can see that dense smoke is being released from the high and big chimneys。 those dirty and poisonous substances are flowing into the rivers that we use for drinking water and millions of tons of waste products are heaping around to change this condition? More and more countries are trying to work out some effective means to bring it under control, but no great success has been made.一旦沒有人想對他的環(huán)境的保護。有幾個人在地球上,自然資源,這大概是無限的。 現(xiàn)在,一切都不同。世界已經變得過于擁堵。我們正在利用我們的自然資源,并提出我們的水坑與危險化學品的環(huán)境。假設我們接著如此下去,地球上的生命將無法生存。 我們認識到,假設有太多的魚從海中,不久將會都不剩了。但是,現(xiàn)代化的捕魚方法,森林就會消失。但是,我們仍舊使用強大的機械砍伐越來越多的樹木。我們都明白假設河水被廢棄物污染的話,我們只有死路一條。然而,廢物產品配置放入河流。我們明白,假設對目前的速度崛起在人口接著,在幾年內,?假設我們多吃蔬菜,少吃肉類,將會有更多的食物。飼料作物用地的5倍多的人建議,土地上的動物將被保存。我們的天然資源,才可以長久,假設我們學會recycie主題。世界人口就不會增長如此之快,假設人們使用現(xiàn)代化的生育操縱方法。最后,假設我們可以人們去考慮的征詢題,我們有毒品和香農在今后更干凈的星球城市的環(huán)境The Surroundings in CitiesWe have to admit that, paratively speaking, our cities are not so clean and green as those in the developed countries.There are not adequate trees, lawns and flowerbeds in such big cities as Beijing, Tianjin and Shanghai.
