What' s more, every citizen should realize the seriousness of the problem and make concerted efforts to protect our environment. In addition, planting trees helps improve and beautify the environment.
譯文：保護(hù)環(huán)境
我們生活的世界正變得越來越難以忍受,因為對環(huán)境的破壞. 禽流感和SARS的是兩個典型的例子,對環(huán)境的破壞,可能危及自己的生命. 此外,森林破壞,水和空氣污染導(dǎo)致減少種植業(yè)土地及不愉快的天氣.
嚴(yán)重的問題,看來,我們可以得出一些措施來對付它. 首先,當(dāng)局應(yīng)該采取的政策是"可持續(xù)發(fā)展" , 法律和有關(guān)環(huán)保工作應(yīng)該要付諸實施,執(zhí)法不嚴(yán),正如我國政府一直在做的事.
何況, 每個公民都應(yīng)該明白問題的嚴(yán)重性,并共同努力,為保護(hù)我們的環(huán)境. 此外,植樹有利于改善和美化環(huán)境.
3.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.
