I think that progress is not always good. Having acquired many benefits from progress, we should still notice that it sometimes leads to severe side effects. For example, industrial revolution, the most prominent progress in human history, has totally changed lives of people, who live in a convenient modern society now. When factories were built up in series, the harm to environment was also drastic and almost hard to imagine. Moreover, human was so proud of their great achievement that they overlooked the negative effects caused by progress. When people realized that they should stop their pace and try doing something to save their mistakes, it was too late. From the above example, we can realize that progress do not always bring positive results. But, on the other hand, we should also notice that progress is an essential trend in human history. It can almost be viewed as human nature. The most vital thing is not to cease the trend of progression. Instead, we should pay more attention to the possible negative results while enjoying the benefits from progress. -- I haven't practiced English writing for a long time. Please give me some advice.
