TUCSON - Wednesday was the 50th Earth Day we have celebrated and we are seeing pollution at their lowest levels in that span, but a lot of that has to do with the stay-at-home orders.With less people driving cars and going to work we are seeing air pollution clear up quickly around the world, but will it last?
