 Yeah, so there are patches in the ocean. Within each of the oceans, there's an enormous kind of circular current in the middle, which they call a gyre, and they kind of spiral inwards, and they take lots of the plastic that's floating in the ocean and ends up in them. So you go out into the middle of the Pacific, and there's one in the north and there's one in the south, and they call them the garbage patches, and there's this huge amount of plastic out there.
