(Projoy) It's true that trees fix carbon rather than letting it float free as CO2 but the number needed to make any difference is impractically large particularly considering the rate the Amazon jungle and other areas are being chopped down. Trees are nice but have become sacred, which is just silly. They undermine buildings, obscure the sky and the view, drop leaves on the railway line and are even allowed to obscure signals. The biodiversity of tree-free railway cuttings was incredible. Down with trees! BTW I don't quite understand your aversion to printed paper. I get cards all the time from my nieces in addition to all the emails, which is nice, and far better than when they were young teenagers and sent me electronic Christmas cards. Sod that.
[Rosie] Well, I suppose it's a personal preference, but I just find dealing with paper irritating these days. It becomes clutter very quickly. You can't miniaturise it and file it conveniently in a sensible folder system on a HDD. Cards and the like seldom express sentiments profound enough to be worth keeping, and for the most part are ritualistic and purposeless. Almost anything that could be said in a conventional letter could be said in an email, which is far more keepable these days.
