how many
It's interesting, how many trees are cut down in a year on our planet? And how much of them are planted? Only for manufacture of paper or Chinese chopsticks several millions of trees per year are cut down!
Let's take, for example, manufacture and sale of computers. It would seem, the computer should reduce quantity of paper work. But did you face the book-keeping which exists in any company producing accessories for computers? At their transportation, sale - everywhere there is a book-keeping with a heap of paper work.
So we again move not forward, to progress, but to simplification of physical work - and no more. And we still continue to cut down woods. Faster and faster!
