I do, because it's pretty easy and/or forced on me. Things like composting I do 'cos I quite like gardening and this is part of it. These gestures have bugger all effect on the potential environmantal catastrophe approaching so, having light bulbs that are crap and not getting freebags at shops so that politicians, retailers, Brussells and smug greenlites can say they are doing their bit whilst they jet off round the world, eat out of seasons food at home and in restaurants etc gets on my tits. It's futile gesture, I'd rather go down with the band playing.
