Car and Air Pollution
Too many cars have created a lot of serious problems in our

world. Besides congestion, accidents and fast fuel consumption,

cars are responsible for a good part of air pollution in big

cities. All the time, they are pumping huge amounts of waste

gases into the atmosphere. These gases are very harmful, causing

disease and even death.
One possible solution is to design and develop clean cars and

clean fuels. In Shanghai, some of the public buses begin to run

on natural gas, which does not give off as much carbon dioxide as

the petrol. But it may take decades for the new models of clean

cars completely replace the traditional ones.
Another solution is to develop modern public transportation

systems and restrict the use of private cars. If the price of

petrol rises constantly and the public vehicles are efficient and

convenient enough, most people will not buy private cars. And the

total number of cars in big cities will reduce greatly.
On the whole, the elimination of air pollution needs the

collective efforts from the government, the public and the

environmentalists.
