第一篇: Environmental problems are becoming more and more serious all over the world. With the development of industry and agriculture, cars make great noises and give off poisonous gas. Trees on the hills have been cut down,and waste water is being poured continuously into rivers. Furthermore,wherever we go today carelessly disposed. The whole ecological balance of the earth is changing. Massive destruction of environment has brought about negative effects and even poses a great threat to man's existence. We must face the situation that exists and take actions to solve our environmental problems. For instance, new laws must be passed to place strict control over industrial pollution, the pub!ic must receive the education about the hazard of pollution and so on. We hope that all these measures. 第二篇: With the improvement of our living standard, more and more people can afford a car. As a result, our roads are more often than not crammed with cars. However, with more and more waste gas being discharged by the cars, the problem of air pollution becomes even more serious. So nowadays we advocate to lead a low-carbon life. My suggestion is we should ride bikes more often instead of driving cars.By riding a bike, we can not only exercise our body but also protect our environment. Why not have a try, my dear friends? 與我們的生活水平的提高,越來(lái)越多的人都買得起汽車的..因此,道路往往沒(méi)有堆滿了汽車.然而,隨著越來(lái)越多的廢氣排放是汽車、空氣污染問(wèn)題變得更加嚴(yán)重.所以現(xiàn)在我們提倡過(guò)低碳的生活. 我的建議是我們應(yīng)該更經(jīng)常騎自行車而不是開(kāi)車騎一輛自行車,我們不僅能鍛煉身體,也能保護(hù)我們的環(huán)境.為什么不試試,我親愛(ài)的朋友?
