I meant to add in the Williamstown post about pigs. The pigs who litter. Daniel recently mentioned somewhere where people had just left rubbish everywhere. I see this happen on the lawns outside the State Library often. The grass outside St Pauls suffers badly, and the small area of grass at the City Square. These are all locations where there are plenty of bins.
But credit where it is due. The good burghers of Williamstown do not litter their beach side park, and nor do their visitors either. Not a wrapper, not a butt, nothing. While I have seen older people litter, it seems to be mostly young people who do the damage. Might I also suggest it is socio-economic too?
