To be a responsible citizen you usually help the environment. For example you would pick up trash or help animals that are hurt or lost. So like after the trash people come and take the trash they would usually drop something. A responsible citizen is one of those people that would go out onto the street and pick up the trash that they left even though it wasn’t yours. Or if there is a lost dog out on the street you would go out get it and take it to the vet. After that you would like put up signs so the owner could find it. That is what responsible citizen is.
