Thursday on RadioWest we’re talking about northern Utah’s perennially poor air quality. While people have no control over the weather and geography that team up to trap nasty air in the valleys, they can influence one very important factor: how much air pollution they put out. So here are some questions: Who’s responsible for our mucky air? What, realistically, can be done about it? And what can we learn from other cities that have cleaned up their air? We want to hear from you, so we hope you’ll join us.
