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 people
would use them instead
of driving. For example

from having a car
by making it more expensive. Today many people

owners, many of them would avoid buying a car
