I could have gone with something much more simple, showing my trash-eating Robo-turtles doing their tasks, but the question was how can I show more and make something more than just a scene in the ocean. After many hours of trying to come up with something extensive, I had this story, some people in our new society live on some type of a ferry and guard the oceans and their residents. I know for a fact that was just the thing I was looking for.
