Unless you have pinaciphobia, the fear of lists, MNN has just about everything to suit your "listicle" needs. We've compiled the best of the best and the worst of the worst, from the best green skin-care products to the U.S. cities with the highest pollution levels. We've got top 5 and top 10 lists for just about anything you can think of, and we add a new list almost every day, so check back frequently — you might just learn something. (Photo: Flickr)

 

If you love lists, you're probably also an infographic fan, and we've got plenty of those, too!
