[Santiasco] Alerta Ambiental

I did not see the air of Santiago that bad for a long time. 

The mayor of the Santiago declared an "alerta ambiental", which means restrictions on 1/3 of cars without catalytic exhaust pipe, prohibition to burn wood, and advice to avoid physical exercise for all:

It is bad (and indeed according to the standards of North America this is the worst category) but note how this situation is only half way in the scale of categories of pollution alert for Chile:


Last winter (remember that it is Winter in the south  when it is Summer in the north) the pollution went all the way to "pre-emergencia" in Santiago, and this year some cities already went to "pre-emergencia" and "emergencia". 

And we are only end of may, at the beginning of the winter: the worst month is supposed to be August...
