An uninhabited island in the South Pacific, Henderson Island, has been found to be full of trash, mostly plastic:
38 million pieces of plastic waste found on uninhabited South Pacific island
I suppose if it was a destination for tourists, everything would have been cleaned up.
Supposedly a lot of the ocean fish have plastic in their organism:

More plastic than fish in oceans by 2050
I know India has banned plastic bags, although I don't know how strongly that is enforced. It's good that you can get paper bags in most large grocery stores in the US. A total ban might help somewhat, although as seen in the first article, various plastic items are the source of pollution.
Yep, I heard about this last week.
Actually though the island is uninhabited, it does have an owner. A collective one. All those morons who deliberately toss their recyclables into a trash can when there's a recycle bin right there next to it, just to be ignorant. They own the place. And they should go clean it up.
Mind you, they don't own the island as in the land mass. Just the plastic on it.
