Living in Vietnam, I concur. It is literally the culture to throw stuff everywhere and not care about it. Someone else will pick it up. Except someone else doesn't and there is no way deal with that since there is so much trash.
Outside my apartment, there is a river. It used to be more of an open sewer. Eventually the government started sending a barge with two guys on it down the river multiple times a day to pick up the trash. The barge gets maybe about 5% of the trash it passes since the river is much wider than the barge. Because there is a daily tide, all the water in the river flows out to the larger Saigon river... which heads to the oceans.
I wish I could post pictures here easily... I have lots of them. It is everywhere in this country. It is sad.
Well, I imagine a significant portion of how you get to be a 1% contributor" is via things like that. If people don't care, you end up like Vietnam (as mentioned in a sibling comment, I don't have any personal experience in that country.) You may as well ask "why are we constantly running media blitzes to get more money for breast cancer care and research? They already have plenty!"
