Cars in our cities For a few decades, we have witnessed the increase of the car fleet in our cities. From the organisation Urban Cities we have wanted submit for debate this matter, and we have heard arguments in favour and against it. To start with, some people argue that it is totally necessary to have a car if you have children. Apart from this, they think that walking or riding by bike is not a real alternative because you need to be fit. Opponents of this view say that cars pollute a lot and, as a result, there are a large number of cases of respiratory diseases. Beside, cars are very dangerous for pedestrians. All things considered, we must not forget that we are living in a comfortable society. Any attempt to make a change is interpreted as a direct attack, but another way is possible. For instance, in the Netherlands, a lot of parents take their children to school by bicycle. People of all ages ride their bikes to go anywhere and no matters the weather.
