Should be cars banned in the centres of the cities?

Nowadays, most people have their own car. In a survey that was carried out here in Spain, most of those who were asked said that they couldn’t live without a car. It would be too difficult for us them to go to anywhere because of the madding crowd.

It's true that cars are a must in people's life but at the same they are a major factor of pollution. What people haven't tho0ught about is that one car pollutes the air less than twenty cars. So, it is more convenient to use public transport instead of their own car, if you think about nature and the air you breathe every second.

Another problem are the frequent traffic jams that happen mostly because of careless drivers of the rush hours. No one would like to be in the centre of Barcelona at 8p.m.

People should use public transport more than their own car. First of all because it would be cheaper. Secondly, because it would reduce the pollution rate by approximately 80% and the city would be also less noisy. All these improvements would make our life much easier, because unpolluted air makes our bodies healthier and we can do as much physical effort as usual, but with less energy consumed.
