人類和環(huán)境 Man and His Environment
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 reserviors 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
縱觀歷史，人類改變了自己的自然環(huán)境，以改善自己的生活方式。隨著技術(shù)的工具，他改變了地球的許多自然特征。
他將林地和草原改造成農(nóng)田和河流湖泊和水庫，用于灌溉和水力發(fā)電。人類還通過排水、穿過群山、修建公路和鐵路來改造地球的表面。然而，人類對自然環(huán)境的改變并不總是有有益的結(jié)果。今天，空氣和水的污染對地球的健康是一個越來越大的危險。每一天，成千上萬噸廢氣機(jī)動車輛的排氣管排出。工廠釋放的煙霧污染了工業(yè)區(qū)的空氣和周圍鄉(xiāng)村。水的污染是同樣有害的'。海洋的整個生態(tài)平衡正在改變，工業(yè)廢物已經(jīng)使許多河流沒有生命�，F(xiàn)在的環(huán)境保護(hù)比以往任何時候都更加緊迫。正如我們所知道的，大規(guī)模的破壞環(huán)境帶來了負(fù)面影響，甚至對人類的生存造成了巨大的威脅。
對這些問題漠不關(guān)心將意味著自殺。因此，必須采取有效的措施，并通過法律保護(hù)環(huán)境。否則，人一定會遭受這種缺乏對他的生活環(huán)境的關(guān)心所造成的嚴(yán)重后果。
