Does human harmed the Earth or make it a better place to live? I believe that the earth is being harmed by human activity even though we live more convenient than before For centuries, people keeping on changing their natural environment to have better life However, all these make great damages to the Earth The most obvious damage is the decreasing of the forests In china, many areas in mountains and are used for farming lands Lots of trees are cut down for building The result is deserts occupy more place in north, while there are more floods in south in summer The second damage is the pollution Specifically in large cities, factories and automobiles make air full of dust and mist Even in midnight I can hear the noise of car running on the way I remember when I was a little girl the river is so clear that we children often jumped into it after class But now it is so dirty that nobody wants to touch it We often miss the blue sky, beautiful river, flourish trees and flowers How pity it is if we can only find them in dreams Some might argue people have made great progresses in the modern society One can travel the entire world in several days by taking airplane Mother can hear her son`s voice by telephone and fell free about his health who worked faraway Yet, natural, the most beautiful and magical thing in the world, is damaged as a cost of all the modern technologies In sum, I concur that we should cherish our environments Changing our life is important, but be care for mountains, lakes, forests where we live with everyday
