I (this is something I do) suggest keeping a trash bag and a pair of rubber gloves with you at all times, so when your out and about and see litter pick it up. Also, if you see someone littering yell ((((((EARTH MURDERER))))))), while you jump up nd down pointing an accusing finger, hahaha. Ok, maybe that's a bit melodramatic, but I know if I were the "EARTH MURDERER CULPRIT" I would be UTTERLY EMBARASSED to be in this humiliating spotlight. What if the punishment fitted the crime? that is what exactly happens in this Belgium PSA.
