Why do people throw chicken bones on the ground?

I know some of it is animals pulling stuff out the trash but also some of it is people throwing shit on the ground. I’ve seen people throw whole boxes of wings out their car window. What is the psychology of someone who would do that? What about the social contract? What about mores? Do we even live in a society?

It isn’t even all about dogs eating them it’s just who would wanna see trash everywhere. This is stuff is expect in like New York or somewhere with no laws or morals like New Orleans sorry New Orleans

edit: if you’re gonna be racist take it to the other DC sub
