人類和環境 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境，以改善自己的生活方式。隨著技術的工具，他改變了地球的許多自然特征。
他將林地和草原改造成農田和河流湖泊和水庫，用于灌溉和水力發電。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，人類對自然環境的改變并不總是有有益的結果。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，成千上萬噸廢氣機動車輛的排氣管排出。工廠釋放的煙霧污染了工業區的空氣和周圍鄉村。水的污染是同樣有害的。海洋的整個生態平衡正在改變，工業廢物已經使許多河流沒有生命。現在的環境保護比以往任何時候都更加緊迫。正如我們所知道的，大規模的破壞環境帶來了負面影響，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，并通過法律保護環境。否則，人一定會遭受這種缺乏對他的生活環境的關心所造成的嚴重后果。
