Of course it is selfish behavior, people everywhere know that littering is against the law, harmful for animals and an eyesore. It clogs up storm drains and depending on what it is can leach chemicals into the water. You have to be under 5 years of age not to know all of this ! So for people to continue doing this type of thing and not to mention-failing to come back and clean it up later- they have to be only thinking of what they 'want'. And that is selfish.
