My bank has been in touch to tell us that from now on, in order to save paper, more important information will be sent by email, not post. But I bet I'm not the only customer who, on receiving any important email, promptly prints a copy and keeps it safe in a file. So from now on with each email, the bank will save a sheet of paper but I will print a sheet of paper. And thus shall we save the planet . . .
Incidentally, if you prefer to save all your documents digitally rather than on paper, that is entirely your right. As we saw last week, computers never go wrong.
