Recently, there have been many letters regarding poor air. Everybody seems to have the perfect solution, but the air isn't getting better.
Sure, synchronizing stoplights or moving expensive oil refineries will help, but take matters into your own hands. If you really care about reducing the inversion, don't drive any place you are able to walk to. If it's not completely necessary to make the trip, don't.
We all know that driving less will help our air, but so far, not enough people have acted on that knowledge. Everybody thinks that one more car on the road won't make a difference; the honest truth is that if you have driven somewhere unnecessary, you are personally responsible for the inversion.
