well, all rivers eventually lead to the ocean somehow. so, the litter flows along, and it goes into the ocean, then sea animals think the litter is some type of food, eat it, and die. or, like those popcan holders, birds and other sea animals get stuck in those and get even more tangled trying to get out of them. so that's how litter in the rivers impact the ocean. hope that helps ya out!
