Car and Air PollutionToo 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.
