With the development of world, many kinds of new industry factories come out. And they bring people a lot of new objects that can improve our lives. But any of these invention hardly can avoid bring environment pollution except solar energy system. Even new technology cannot cleanse the earth, how about human activities? The answer is obviously not. I don’t agree the opinion that human activities can make the earth a better place to live.
In the history of earth, there is no organism have destroy the earth like human being. For instance, in order to win the war, many country started researching nuclear weapons that have ruin the environment of some places on earth, like Hiroshima, at the same time, the firestorm that leveled Hiroshima after the atomic blast.
People cannot leave electricity nowadays. But as we all know, electrical equipment can produce carbon dioxide. The more electrical equipments, the more carbon dioxide. The more carbon dioxide, the higher of temperature. That can bring greenhouse effect. And Melting glaciers will followed with the effect. So our earth would be ruined by ourselves and we don’t recognize it. People can leave more pollution in the future. We cannot deny that we keep making pollution everyone, including sewage, life rubbish, and car exhaust. And we don’t stop doing this even the energy of earth is running out. We cannot make a solution to the pollution, the exhaustion of earth. That would accelerate our deaths. If we really wanted it, we can improve the quality of life, if we really wanted it, we can let earth be better. 这次字数还稍微查差一些,主要分论点里面想不出来好的例子,希望改的同学多提点意见; 也有些句子中式了,见谅~ |
