Colorful flat illustration depicting a river carrying litter from a town and bridge into the sea, where a factory and ships also contribute to pollution.

An educational illustration showing where marine litter comes from in one scene. In the top left there is a green mountain, with a clean river flowing down through a town with houses and a bridge, and then into the sea on the right. Along the river there are trees and bushes. Around the houses and on the bridge, everyday trash such as plastic bottles, plastic bags and cans has been littered, and the rain is washing it into the river. On the coastline to the right there is a factory with chimneys, and in the sea there is a large cargo ship. In the waves you can see plastic waste that has flowed from the river, and some garbage coming from the ship and the factory area. The overall style is a colorful, friendly flat illustration for Japanese school textbooks, with slightly simplified, cute shapes, bold outlines, no text or arrows, 16:9 horizontal layout, shown from a slightly top-down perspective.
