Nowadays,cars have become a very common vehicle in our life.As the most important transport,cars have improved our modern life in many ways.However,cars also bring about so many problems for people,which should be given more attention than any time before.

    Cars give people the ability to travel to any place they like.Many people begin to travel frequently.This helps people connect with each other better than before.A more obvious influence from cars is the large number of jobs that they create.Jobs in several fields open up thanks to cars,such as jobs in car factories,gas stations and highways. This is a huge positive influence on society because they greatly reduce the unemployment rate.

    At the same time,the problems that cars cause seem to be more and more serious.A mass use of cars is bound to have some negative consequences.The widespread use of cars has led to serious traffic jams in cities.They have resulted in a reduction in the use of public transportation in many cities.The need to use and develop public transportation has been much discussed and confirmed.And also,car accidents create a number of injuries and deaths. There are hundreds of thousands of them worldwide every year.Gas let out from the engines of cars pollutes the air in cities around the world.Air pollution creates serious health problems and causes many people to die from it.It has become one of the most serious problems today.Efforts to develop pollution-free engines may be the final solution to this problem.

    In conclusion,people should not only enjoy the benefits of cars,but also aim to deal with the problems cars have created.At the same time,the government should improve city traffic systems,encourage people to use public transportation,make efforts to improve road safety and encourage the usage of fuels that are low in pollutants.Only in these ways can the benefits of cars outweigh their harmfulness.
