I think he was trying to say this guy's trash gets blown into the neighbors' yards, all of whom put effort into making their homes look good only to have this one's trash tossed into it. I think he may have been asking for advice on how to deal with this neighbor.
Anything that makes the neighborhood look bad, you can at least try to bring it up with the city, there may be ordinances regarding it (like in some areas it's plain illegal to have a car on blocks in front of the house, in other areas it's not). First though, several of the neighbors (especially the ones right next door) should get together and either write a letter to this person asking that he clean up his act, or go to his house as a group or select someone to represent the group and go with a letter signed by everyone asking him to clean up.
Naturally he'll laugh in your face, but you can say you made a good faith effort. At that point, the neighbors on each side just build really high wooden fences. 🙂
