Milestones

Los Angeles just ranked number one for air pollution again, and it has officially surpassed the four million mark in terms of population.

Pollution

I've heard that the smog levels in Los Angeles have significantly improved over the last couple of decades. Having no earlier point of comparison, I can't really gauge the pollution level. Most days consist of clear blue skies, but some days, like the last two, are hazier and there seems to be a filmy coating in my mouth. But perhaps that is my imagination.
