Make Our Cities Green
With industries and business developing quickly, the number of trees in many big cities has dramatically reduces. Efforts are being made to prevent people from cutting more trees. But a lot of trees are being destroyed by people who have never thought of the importance of green plants.
Making cities greener has many advantages. First, it can make our air cleaner. Some researchers have proved that trees can reduce the amount of carbon dioxide in the atmosphere through absorption. Second, it can make our cities more beautiful. With trees and flowers everywhere, living conditions can be improved. Finally, it can produce timber----an effective way to solve the problems of limited supply of natural resources.
Making our cities greener requires nationwide efforts. People in every field should not only know about the importance of keeping the quality of urban environment, but also take common action to plant more trees and flowers so as to improve our living conditions.
創建綠色城市
與工業和商業發展迅速,樹木的數量在許多大城市已大大減少。正在努力阻止人們削減更多的樹木。但是很多樹木被摧毀的人從來沒有想到綠色植物的重要性。
使城市更環保也有很多優點。首先,它可以使我們的空氣更清潔。一些研究人員已經證明,樹木可以減少大氣中二氧化碳的.吸收。第二,它可以使我們的城市更美麗。到處都是花草樹木,可以改善生活條件。最後,它可以產生木材——一個有效的方法來解決問題的有限的自然資源。
使我們的城市更環保要求全國的努力。人們在各個領域不僅應該知道保持城市環境質量的重要性,也採取共同行動,以種植更多的樹和花,以便改善我們的生活條件。
