It's a shame that the portobello pupils seem to be undoing a lot of good that is done in the Figgate Park.
It might prove benefical if the Environmemtal Warden,[I think that's what they are called] popped into the park at lunchtimes now and again and had a word with the offenders or just let the pupils see that someone cares about this area.
I'll certainly have a word with any kid or adult I see dropping litter in this area.
It's something the local PTA could look at and encourage most of the kids at school to look after the park and such like in their area.
