Litter and dog mess abound. Stop it, it's infantile and costs money to pick and clear up. In these times of austerity we need to save as much money as possible and picking up litter must cost the council (The tax payer really) a lot of money. Plus it's not very aesthetic.
I agree about all the litter lying around but not everyone leaves their dog mess where it drops! I clean up every single time after my dog - if only more people were as responsible then there wouldn't be as much of it for people to step in to
