I don't need a study to understand the benefit of what I can observe with my own eyes. I have lived in places in the U.S. where trash accumulates on and around the streets. The plastic trash just sits there. It doesn't degrade under heavy rainfall or years of neglect, it just continues to accumulate. Not every place in the West (or even the U.S.) has ideal sanitation services.
