Cities are no longer cars' territory and our biological clock

Nowdays there are many kinds of pollution, but air pollution is the one that has the greatest impact on us. With the big number of vehicles on the road we are heading towards smoggy skies and dirty air if we do nothing to stop it.

How does pollution affect us? There are a large variety of effects, for example: there is a higher risk of heart diseases, cancer, asthma and other respiratory diseases. Plants and water are being contaminated, which are eaten and drunk by animals. The pollution then ends up in our food chain and finally gets to us.

The list of cities with a low air quality has increased over the years, due to this reason, more and more city centres, such as Sevilla (Spain), Norwich (Britain) and Paris (France), are pedestrians’ territory.

To conclude, I reckon that we have to raise awareness and try to do something for changing these alarming problems, since it's our responsability and by the time we are old we will be able to say that we have looked after the planet.
