one of the most harmful technological innovations of all time is the automobile With the development of the science and technology, more and more technological innovations were used in the real life and they have changed our life a lot. At the same time, technological innovations took us not only confident and benefits, but also some harmful consequents. The most harmful technological innovation is the automobile. As We all know, automobile as the main transportation vehicle has brought lots of convenience for our life. We can reach the destination more quickly. Nowadays people use automobile everyday and cannot leave the automobile’s help in our daily life. It enhances our working efficiency; it can as well create a greater economic efficiency for the society. However, the automobile has also brought much harm for us. First of all, automobile production requires a lot of steel, during the producing process it can lead to a massive pollution, destroyed the ecology seriously. As we know, London was known for its dense fog, this is the evil consequences of the environmental destruction. Meanwhile automobile production also leads to energy shortage. Recently petroleum price rises once more, there were tight supplies of oil in many places, with the increasing number of the private cars, more and more energy was needed. and the fact precisely resulted in the energy shortage. Third, the automobile discharges lot of waste gas. It not only seriously polluted our living environment, but also caused the greenhouse effect .what’s more, because of this air pollution, many citizen have been suffering from bronchial disease. Fourth, the issue of traffic accident has been brought public attention, because of the drunk driving the traffic accident occur frequently, simultaneously, traffic jams has also become the most serious problem in many big cities, which was already serious interferes with people's normal life. in my opinion, people become more lazy because of the automobile, so we should not be too dependent on automobiles. We can use bicycle instead of it to protect our living environment. That’s all thank you.
