Go to the place and see how far you have to walk to throw out your trash. Many places outside of Downtown, there isn’t a public use trash can for several blocks. Trash bags get ripped apart by animals or cheap bags just shred on their own. Additionally, Sanitation is a large contributor. Either loose trash left behind or trash escaping from old trucks with a poor seal. And then there are drivers who throw their food wrappers and drink cups out the window or dump them in a parking lot
