This document is a sort of humoristic picture to make the public aware of the way they act. It is said that dropping litters make you looking like dirty pigs.
Dirtypigs.org is the name of this organisation (if it does exist !) who is fighting against littering anything everywhere . The main target is youngs and food you can eat walking, as junk food, and they don't manage to throw the boxes in garbages cans. This picture wants to make people realize that keeping Britain tidy isn't so difficult.
j'espère que ce n'est pas trop court et que cela t'aidera à te mettre sur la piste
