I always fear for that day when our air will no longer be so pure and what it will do is make us sick, maybe I exaggerate, but those figures of 4 million a year just because of air pollution, it is scary. And my other fear is water, we have to take care of it, one day I fear that the next wars will be over this vital liquid.

I understand that in Japan there are stations to breathe clean air through masks. I don't know how true it is, but I wouldn't be surprised, Japan is a very industrialized country, as well as China.

Thank you for bringing us this valuable and thoughtful information.
