In Twenty years, there will be fewer cars in use than there are today.

First of all, nowadays, air pollution is crisis issue involved all the world. This problem seems very serious and if it does not stop it lead to significant disaster. Car pollution is one of the major reason of air pollution thus I strongly agree with the prediction of fewer car will be exist in towns, the gases and the pollutes that emitted from car engines cause heart and lung problems, various form of cancers even, It leads to born infants with genetic disorders.

Secondly, the problem of traffic is a today headache. Cars are convenient vehicle to travel in the city or out of it. On the other hand, the roads have not enough capacity to cover all of cars and vehicles thus anyone is the witness of sticking in traffic jam and get nervous. People react this uncomfortable situation by shouting, put the others drivers in rage or holding hand on horn so cause sound pollution instead. people tend to use their cars instead of public transportation, this leads to enormous car factory producing , they benefit from this business in spite of revise or promoting fuel burning or some alteration that inhibit air and sound pollutions.

Finally, the resource of the fuel energy in the world is restricted, gas and petroleum are expensive. Excavation of this fuel is hard and time consuming, many scientists invent new fuel for vehicles such as sun energy and atomic energy but they have not been efficient till now and I do not think it will work for fewer twenty years.

To wrap it up, in my opinion in twenty years, the car will gradually vanish and another vehicle such as airplane or some innovative one will be replaced, in addition governments encourage people to use from public transporter instead of private vehicles. I hope promising future for all people in the world to have more convenient and safe transportation.
