Although this news piece may be two months old, I still found this to be very intriguing. According to a news piece on KSEE 24, our valley air quaility is the best it has been in the last thirty years, which I personally think is amazing considering that we do live in the Central Valley where a lot of the pollution settles. According to this article ozone violations have gone down almost in half since 2002. I think that this kind of news gives those who live in this area some hope that our air quality can and will improve even more in the years to come. What do you think? What do you think has caused this improvement of air quality?
