If you have ever been to Salt Lake City, Utah in the winter, you know to expect cold weather and snow, but poor air quality is also synonymous with a Salt Lake winter. As natives of Salt Lake know, we are stricken every year with a nasty inversion that traps all of the valley’s pollutants. In other words, all the fumes and gases from cars, factories, smoke stacks, etc. get trapped in the Salt Lake Valley, causing thick haze and dangerous air. When I say that the air is dangerous, I mean that it is so polluted that breathing it for a prolonged time is comparable to smoking cigarettes.
