Sort of a tangent, but i have never experienced so much soot as i do living here. lots of cities have soot, but then lots of cities have emission controls and dont have cars out of a 1950s movie. have you ever seen such old trucks!
Anyway, where i would probably clean soot off a balcony once a week or so back home, i do it daily here. i went to a cafe in my area the other night, one of the smokeless nights, and sat at a cafe. the busses screamed and poured out black smoke, the trucks had tailpipes pointed at the sidewalk, washing us in pollution.
after i ate my sandwich, i touched the papers i had. in that short time, it was coated in soot. my fingers were black. imagine what this is doing to your kids, etc. And it wont get better soon. the mayor owns one of the large bus companies apparently and you dont want to be anywhere near one of his polluting monsters.
The lies change, but argentina stays the same. its not for the health conscious.
