Pollution

Nowadays we have important problems of pollution, especially in big cities like Madrid, Sevilla or Barcelona. That cities and others form all around the world have pollution problems and it is really difficult to solucionate them. 

It is true that there are many policies, national and international, that try to solucionate these big problems, but in my opinion, is is insufficient and inadequate. Many days, if you live in a big city like Barcelona and you try to look  the clouds in the sky, you can't. Normally the sky is covered by a smoke cloud. However, situations like that are presents in many cities around the world. When you go for a walk in the streets of a big city you will see always a lot of traffic and that is the principal cause of the smoke cloud. 

There are many options to solucionate pollution problems. The first one and the most easy to do is to take public transport (train or bus) to go at work and not to take the own car, But there are many people who don't try to do the effort. 

However, some cities try to do something in their own, like a bycicle day or a public transport day. The only problemof these initiatives is that it is only one day a year, and it should be all the year. For example, in Barcelona, had got success the initiative of 'Bicing', and now there are many people who uses the bycicle and not the car. 

I know that these are poor solucions in front of a big problem. All the society should aware about this, because it is our world and our responsability to take care of it.
