Everything seems a one stop shop for you though wittonite? All comes back to immigrants.
Size of the population as a whole is an issue. All of 'you' who have bred have increased the population, damn (sic) you. Just lazy pointing at one facet. You are part of the problem down south after-all... you should go back to where you came from! (I think you know me long enough to know I'm being tongue in cheek - to an extent - and that you probably agree many of the locals would agree!
But it isn't 'that lot' pumping crap into our rivers and streams, destroying lakes in our national treasure of the Lake District (and other areas) or the lack of balls from the government (and/or governments ) to bow down to profits, instead of doing proper planning, forcing brown field sites to be used first, proper drain-aways for new estates, or letting the rail system go to rack and ruin, the rape of our beautiful ancient forests and the murder of trees centuries old for a failing rail project which is now only going to go half the way it was meant and to the place it wasn't needed and so on and so forth. It is big business - who have many an mp in their pockets - allowing so much destruction and the current government for not jumping on the green economy to be a world leader far, far, sooner. And this before I get onto the destruction of the seas which is also not just down to those darn immigrants.
