Yes gilly "The Messengers" need to make sure whilst they are delivering "The Message" if they want to be taken seriously, that they are not leaving conspicuous amounts of waste, don't travel unnecessarily, don't drive diesel cars (yeah thanks for that advice Gordon Brown) so detrimental to youngsters, especially those who live or are schooled near busy roads, not to mention mothers carrying unborn children, only drive electric cars, get rid of their wood burning stoves if they have those, whilst delivering the message, to admonish those such as festival goers and travellers who leave piles and piles of crap in their wake, why is it ever okay to think others will clear up your detritus, to give up on flying anywhere. I think we are all fed up with grandstanding celebrities and politicians and their "don't do as I do, do as I say message"
I'll leave it there.
