In Mexico City at least, even if the environmental policies limiting cars are in place, and factories are starting to idle because of COVID-19, our air is still shitty because we’re starting to see a slew of forest fires.
Alike last year, the smoke fills the Mexican valley giving Mexico City a strange fog and burnt smell. I don't really have a memory of this ever happening before 2019... When we cut our forest maintenance budget in like 70%(?) I think.... But I can't really say for sure because early spring is always a bad air season here.
