作文,汽车会在20年后比现在更少

Nowadays,there is an increasing number of people begin to buy cars to make their outdoor activities more convenience.Cars,indeed make our life more comfortable,but do they realize that those cars may also add an element of sickness on our bodies?Despite some people make the statement that there will be more cars in future,I firmly believe that there will be fewer cars in use in twenty years.

Firstly,cars can produce waste gas,which will cause a series of consequences,namely,the green house that make more radiation attend Earth from the sun,cause more people have unhealth lungs.Nowadays,pollution have been seriously impact we human beings' health,about 30 persent of which is produces by cars.Even worse,cars accidents happened more frequently recently not only due to the rapid accumulative number of cars but also because of the cause of foggy whether by produce certain gas,which made a huge potensal danger to our security.

Secondly,people will be guided by goverment to take the bus instead of buying cars.Because petrol can be soon used up if we continue consume it by using cars,and petrol may perform another important way to be used to do research.There is a trend that we come to realize that cars are not the only way for us to go elsewhere.In twenty years,our traffic management will be more efficient for us to travel,for instance,subway will be more fast and extand to a far destination,we need not to travel by car because it is not as fast as the subway does.

Admittedly,cars enable us to do many things in a efficient and valid way than we ride a bike or take the trains.Such phenomenon,however,will not happen in twenty years,as the rapid-developed technology .

Judged by the reams of evidences make above,we can safely conclude that there will be less car in twenty years.
