Has automobiles improved modern life or caused problems? In my opinion, automobile has caused serious problems in our society Because the prevailing use of automobile brings us a lot of environmental harm, traffic accidents, and traffic congestion First of all, one of the main reasons why our atmosphere is being polluted is the using of great amount of automobiles It is quite obvious that the exhausted air which is emitted by automobiles is very dangerous and harmful to human`s health As people drive more and more automobiles, our health is being threatened day by day Furthermore, it is reported that the traffic accident kills more and more people everyday in all around the world Many people also lost their legs, arms permanently during car accidents Many kids lost their parents because of car accidents when they were young Traffic accidents cause many tragedies which occur in our life Traffic accidents bring us a serious social problem In addition to those above, traffic congestion is also a important adverse element which is brought by automobiles Many people have the same experience that they had to wait hours in their cars during a rush hour Traffic jam wastes our lots of time Admittedly, automobile gives us many advantages in our life However, it has more disadvantages It has caused serious problems in terms of environmental harm, traffic jams, and traffic accidents
