初中一年級(jí)環(huán)保英語(yǔ)作文
Throughout history man has changed his physical environment in order to improve his way of life. With the tools of technology he has altered many physical features of the earth. He has transformed woodlands and prairies into farms and made lakes and reservoirs out of rivers for irrigation purposes or hydroelectric power. Man has also modified the face of the earth by draining marshes and cutting through mountains to build roads and railways.
However, man's changes to the physical environment have not always had beneficial results. Today, pollution of the air and water is an increasing danger to the health of the planet. Each day thousands of tons of gases come out of the exhausts of motor vehicles. Smoke from factories pollutes the air of industrialized areas and the surrounding areas of the countryside. The pollution of water is equally harmful. The whole ecological balance of the sea is being changed and industrial wastes have already made many rivers lifeless.
Now environmental protection is more pressing than ever before. As we know, massive destruction of environment has brought about negative effects and even poses a great threat to man's existence. Indifference to these problems will mean committing suicide. Therefore, effective measures should be taken and laws passed to conserve environment. Otherwise, man is certain to suffer from the serious consequences caused by this lack of care for his living surroundings
歷史上的人改變了他的物理環(huán)境,以改善自己的生活方式。借助技術(shù)工具改變了地球的許多自然特征。他將林地和草原改造成為農(nóng)田,使江河變成湖泊和水庫(kù),用于灌溉或用于水力發(fā)電。男人也修改了地球表面由高山沼澤和切斷山區(qū)修建公路和鐵路。
然而,人的物理環(huán)境的變化并不總是有有益的結(jié)果。今天,空氣和水的污染是越來(lái)越危害地球的健康。每天成千上萬(wàn)噸的機(jī)動(dòng)車輛的排氣管排出的氣體排放出來(lái)。工廠釋放的煙霧污染了空氣工業(yè)化地區(qū)和周邊地區(qū)的農(nóng)村。水的污染也同樣有害。海洋的整個(gè)生態(tài)平衡正在改變,工業(yè)廢物已經(jīng)使許多河流毫無(wú)生氣。
現(xiàn)在,環(huán)境保護(hù)比以往任何時(shí)候都更為緊迫。正如我們所知,環(huán)境的巨大破壞已帶來(lái)負(fù)面影響,甚至對(duì)人類造成巨大威脅的存在。對(duì)這些問(wèn)題漠不關(guān)心將意味著自殺。因此,應(yīng)采取有效措施并通過(guò)法律來(lái)保護(hù)環(huán)境。不然的話,人類勢(shì)必遭受缺乏所造成的嚴(yán)重后果關(guān)心生存環(huán)境
