As countries develop, more and more people buy and use their own cars. Do the advantages for individuals outweigh the disadvantages for the environment?
(Word count： 298)
The past fifty years have seen a significant increase in the popularity of private cars. While it is argued by many that using own cars may be beneficial in terms of their time-saving and convenience, yet there still remain some arguments that using own cars results in severe pollution for the environment. Overall, my personal view is that the disadvantages of using private cars are far outweigh their benefit.
When it comes to the advantages, many people choose to use their own cars for the sake of more freedom and fast speed. While it is admitted that public transport provides us with much more economical means of transport, it limits our journey by stations and bus stop. Using own cars, however, give us convenience irrespective of the length of the journey. Take the case of traveling to work by private car as a salient example. You may not need to walk for a long way to your office in case it is far from the bus stop or the station.
On the downside, however, excessive use of private cars may be responsible for serious pollution. Moreover, no matter how comfortable private cars are, they lead to major traffic jams and the shortage of fuel energy. Smoke leaking form vehicles causes extremely bad air that is responsible lots of respitory ailments in human. On top of that, excessive using fuel energy for organising cars may contribute to exploiting coals and fuel to excess, which is incredibly detrimental to environment particularly alternation in climate and weather.
By ways of conclusion, people buying and using their own cars is either beneficial or detrimental to individuals and society at large. Although it cannot be denied that private cars are extremely convenient, the adverse impact they may have on environment is highly severe.
