People in major cities suffer from high levels of air pollution that causes health problems for many. Explain possible reasons for this problem and suggest some solutions.

for years, and some develop dangerous illnesses like asthma and lung cancer. In order to reduce the use of private vehicles, the government should introduce two main policies. The most obvious way to reduce
air
pollution
would be to reduce the number of
cars
on the streets. One way to limit the number of private vehicles is to improve public transport. If buses and trains were comfortable and fast, many

would use them

of driving.

from having a
car
by making it more expensive. Today many
people
can afford to get a small, old

owners, many of them would avoid buying a

. In conclusion, huge numbers of
cars
on the streets of big
cities
seem to be the main source of
air

. In order to decrease
car
ownership, the government should use a combination of policies: to increase the cost of having one and to develop reliable public transport systems that city residents could use
